Factors impacting community living outcomes among former long-term nursing home residents using the interdependence-Human Activity Assistive Technology (i-HAAT) model.

Despite an increased application of social theory in assistive technology (AT) outcomes research, there continues to be a gap in integrating AT conceptual models in research design, data analysis, and results interpretation. This paper merged two preexisting AT models, the Human Activity Assistive Technology model (HAAT) and the interdependence frame for AT into a novel framework, the interdependence-HAAT model (i-HAAT). This model was used to examine the outcomes of former long-term nursing home residents using AT. The model was also used as a framework to facilitate quantitative variable identification and categorization, emphasize the interconnectivity between domain variables, and explore the infrastructural supports necessary for the successful community reintegration of deinstitutionalized AT users. Meaningful integration of theory into practice is the essential next step in generating socially responsive research that addresses AT consumer needs and moves the field forward.

Perceptions and experiences of first mobility aid provision for young children with cerebral palsy in the United States: a mixed-methods study.

PURPOSE: The purpose of this study was to establish and understand the provision process and impacts of first mobility aids for children with cerebral palsy (CP) in the United States - specifically orthoses, walkers and gait-trainers. METHODS: We performed a mixed-methods study including surveys and semi-structured interviews of caregivers of young children with CP (n = 10) and clinicians who work with young children with CP (n = 29). We used content analysis for the surveys and inductive coding for the interviews. RESULTS: Four themes emerged: (1) first mobility aids have mixed impacts and use patterns, (2) there is varied caregiver education and understanding about mobility aids, (3) clinician knowledge, consistency and connection impact care and (4) numerous access barriers exist for families, and there are still opportunities for improvement across all domains. CONCLUSIONS: This research provides insights into the lived experiences of clinicians and caregivers of young children with CP regarding the prescription, provision, use and impact of first mobility aids, specifically ankle foot orthoses and walkers/gait trainers. This study not only provides researchers and clinicians with an understanding of the current status of the prescription and provision process in the United States, but also offers suggestions for improvements of the process and mobility aids themselves. These results have implications for future research, mobility aid, design and the provision process of first mobility aids.

Implications for rehabilitationMore detailed education and training during the prescription and early use process of first mobility aids has been highlighted as an unmet need by many families.The current timeline for participants receiving first mobility aids after prescription such as ankle-foot orthoses and walkers ranges from 2 to 9 months, which may delay access to on-time mobility for young children.Clinicians and caregivers highlight benefits of ankle-foot orthoses such as improved gait and standing alignment but also point out these aids can be uncomfortable and inhibit functional floor mobility. Clinicians highlight benefits of walkers such as supporting upright mobility and independence, but also point out challenges with physical barriers in the community and contributions to poor postural habits. Open discussion of these pros and cons with caregivers may be an important part of the provision process.Understanding the impact of different types and levels of clinician education and training regarding first mobility aids on confidence and decision-making during provision processes is valuable to improve practice and device design.

Caregiver perspectives on powered mobility devices and participation for children with cerebral palsy in Gross Motor Function Classification System level V.

AIM: To describe caregiver experiences, perceptions, and device preferences between a modified ride-on car (MROC) and an Explorer Mini, including perceived changes in participation, barriers, and benefits for young children with cerebral palsy (CP) classified in Gross Motor Function Classification System (GMFCS) level V. METHOD: A subset of data were analyzed from a larger multisite study. Semi-structured interviews were conducted with 10 caregivers of children with CP in GMFCS level V across a 16-week trial with two mobility devices. Each interview was audio-recorded, transcribed verbatim, and analysed using constant comparison methods. RESULTS: Seven of 10 caregivers preferred the Explorer Mini over the MROC. Four themes emerged. One related to the perceived benefits and barriers of each device (ease and convenience is essential) and three related to perceived changes in participation: (1) autonomy enacted through mobility; (2) belonging and being present; and (3) participation recognized as an area of growth. INTERPRETATION: Despite limited consideration of powered mobility for this population, caregivers of children in GMFCS level V reported similar benefits and barriers compared to children in other GMFCS levels shown in the literature. Particularly, caregivers perceived positive changes in their child's participation and recognized the ability for continued improvements in participation when using powered mobility. WHAT THIS PAPER ADDS: Children with cerebral palsy classified in Gross Motor Function Classification System level V are often excluded from powered mobility use and research. Despite this, caregivers reported positive experiences for their children. Caregivers felt that participation in powered mobility led to increased autonomy and overall sense of inclusion and belonging for their children. Most caregivers preferred the Explorer Mini over the modified ride-on car but recognized that both devices had benefits and barriers to use.

Ready, Set, Move! Tracking Children's Modified Ride-On Car Use With a Custom Data Logger.

PURPOSE: To create and implement a next-generation, custom data logger to automatically track modified ride-on car (MROC) use in home and community settings, establish feasibility of long-term remote collection of community MROC use data, describe trends of MROC use, and explore parent perception of the MROC. METHODS: In this descriptive study, a custom data logger was constructed and integrated into MROCs using an Arduino Pro-Mini microprocessor to capture real-time use data remotely. RESULTS: It is feasible to automatically track MROC use in home and community settings. On average, MROC use trends appear consistent with caregiver reports and show higher initial use with steadily decreasing frequency over time, and varying bout duration and play session length, despite favorable caregiver perceptions of the cars. CONCLUSIONS: Remote tracking of MROC use may decrease burden on busy families and provide clinicians with valuable technology use data.

Off to the park: a geospatial investigation of adapted ride-on car usage.

PURPOSE: Adapted ride-on cars (ROC) are an affordable, power mobility training tool for young children with disabilities. Previous qualitative research has identified environmental factors, such as weather and adequate drive space, as barriers to families' adoption of their ROC. However, we do not currently know the relationship between the built environment and ROC usage. MATERIALS AND METHODS: In our current study, we quantified the driving patterns of 14 children (2.5 ± 1.45 years old, 8 male: 6 female) using ROCs outside and inside of their homes over the course of a year using a custom datalogger and geospatial data. To measure environmental accessibility, we used the AccessScore from Project Sidewalk, an open-source accessibility mapping initiative, and the Walk Score, a measure of neighborhood pedestrian-friendliness. RESULTS: The number of play sessions with the ROC ranged from 1 to 76; 4 participants used it less than 10 times and 4 participants used it more than 50 times. Our findings indicate that more play sessions took place indoors, within the participants' homes. However, when the ROC was used outside the home, children engaged in longer play sessions, actively drove for a larger portion of the session, and covered greater distances. Most children tended to drive their ROCs in close proximity to their homes, with an average maximum distance from home of 181 meters. Most notably, we found that children drove more in pedestrian-friendly neighborhoods and when in proximity to accessible paths. CONCLUSIONS: The accessibility of the built environment is paramount when providing any form of mobility device to a child. Providing an accessible place for a child to move, play, and explore is critical in helping a child and family adopt the mobility device into their daily life.

IMPLICATIONS FOR REHABILITATION: GPS OF ROC USAGERide-on cars provided a novel means for young children with disabilities to explore their home and community environments.Children drove their adapted ride-on cars for longer periods of time outside than inside, and in close proximity to their homes.The identification of an accessible route increased driving frequency and drive session duration. Recommending accessible routes and play locations where families can use their adapted ride-on car may be an important aspect of increasing mobility technology use.Because there were a higher number of play sessions inside, it is important to consider indoor accessibility when designing and implementing mobility technology for young children.

Supportive mobility devices across the lifespan in Cerebral Palsy: a modified Delphi study to establish stakeholder research priorities.

PURPOSE: The aim of this study was to co-develop research priorities and identify meaningful research questions with a diverse group of stakeholders representing the CP community for implementation in subsequent research activities. The overarching aim of this research was to 1) Understand the mobility experiences, supported mobility device (SMD) use, and desired participation outcomes of people with cerebral palsy (CP) across the lifespan; and 2) Describe how perspectives of rehabilitation care and professional resources may influence mobility decision-making processes and outcomes. MATERIALS AND METHODS: A three-round modified Delphi consensus study was conducted with a stakeholder advisory panel consisting of three adults with CP, two parents of children with CP, and four SMD providers. RESULTS: The advisory panel identified 11 unique topical categories focused on SMD selection and use, stratified by age group and stakeholder role. Questions or statements within each category were ranked, and top consensus and concordance statements were retained, reviewed, and refined for use in a co-developed focus group guide. Priorities were identified in three main groupings: (1) Age/GMFCS level/Environment-related; (2) Individual with CP/Caregiver need-related; and (3) Clinician/provider partnership-related. DISCUSSION: A modified Delphi process was a useful tool for stakeholders in co-developing research priorities related to SMD use across the lifespan. Drawing on the lived expertise of stakeholders is important in facilitating improved research translation in the CP community.

IMPLICATIONS FOR REHABILITATIONRoutine incorporation of stakeholder voices in research and clinical practice can critically inform teams without lived experience of cerebral palsy to co-create meaningful priorities and focus areas for supportive mobility device provision and use from a lived perspective.Stakeholders identified that access to trial equipment, device adaptability, provider knowledge and training, and a focus on the presence or absence of shared decision-making are among the top research priorities when engaging with individuals with cerebral palsy who use supportive mobility devices.Given the heterogeneous nature of cerebral palsy and evolving mobility needs for individuals across different Gross Motor Function Classification System levels, a lifespan perspective and future-oriented approach to supportive mobility device research and clinical practice are crucial to address device design and implementation as well as barriers to quality provision practices.

Powered Mobility Device Use and Developmental Change of Young Children with Cerebral Palsy.

Mobility is a fundamental human right and is supported by the United Nations and the ON Time Mobility framework. The purpose of this study was to understand the effect of a powered mobility intervention on developmental changes of children with cerebral palsy (CP). This study was a randomized, crossover clinical trial involving 24 children (12-36 months) diagnosed with CP or with high probability of future CP diagnosis based on birth history and current developmental status. Children received the Explorer Mini and a modified ride-on car in randomized order, each for 8 weeks. The Bayley Scales of Infant and Toddler Development-4th Edition was administered at baseline, mid-study, and end-of-study. Raw change scores were used for analysis. Total minutes of use per device was categorized as low or high use for analysis based on caregiver-reported driving diaries. Explorer Mini: The high use group exhibited significantly greater positive change scores compared to the low use group on receptive communication, expressive communication, and gross motor subscales (p < 0.05). Modified ride-on car: No significant differences between low and high use groups. Regardless of device, low use was associated with no significant developmental change and high use was associated with positive developmental changes. Mobility access is critical to maximize the development of children with CP and may be augmented by using powered mobility devices. Results may have implications for the development of evidence-based guidelines on dosage for powered mobility use.

"Kind of empowered": Perceptions of socio-emotional development in children driving ride-on cars.

PURPOSE/OBJECTIVE: Early powered mobility (PM) experiences can be essential facilitators of self-initiated mobility, socialization, and exploration for young children with disabilities. Cerebral palsy (CP) and developmental delay are two of the most common diagnoses associated with motor disability in young children with 1 in 345 children diagnosed with CP and 1 in 6 with developmental delay in the US. The purpose of this study was to explore the longitudinal experiences and caregiver perceptions of socio-emotional development in particular, in young children with disabilities during modified ride-on car (ROC) use. RESEARCH METHOD/DESIGN: A qualitative, grounded theory approach was used. Semi-structured interviews were conducted with 15 families (children ages 1-4 with CP or developmental delay) at baseline, 6 months (as able due to COVID), and 1 year following ROC introduction. Data were coded independently by three researchers using constant comparison until data saturation occurred and themes emerged. RESULTS: Four themes emerged from the data: "Leveling the Playing Field," "Breaking Down Barriers," "Fun and Work: ROC as Toy and Therapy Device," and "Mobility is a Pathway to Autonomy." Conclusions/Implication: Children and caregivers viewed ROCs as both fun and therapeutic, consistently identifying perceived benefits for children's socio-emotional development. This qualitative study provides a better understanding of the complexities and impact of ROCs on children and their families in the socio-emotional domain and may help facilitate clinical decision-making when introducing PM to young children with disabilities as part of a multimodal approach to early intervention.

"That's frustrating": Perceptions of ankle foot orthosis provision, use, and needs among people with cerebral palsy and caregivers.

BACKGROUND: Cerebral palsy (CP) affects roughly 3 per 1000 births in the United States and is the most common pediatric developmental motor disability. Ankle foot orthoses (AFOs) are commonly prescribed to provide support and improve function for individuals with CP. OBJECTIVES: The study objective was to evaluate the lived experiences of individuals with CP and their caregivers regarding AFO access, use, and priorities. We examined experiences around the perceived purpose of AFOs, provision process, current barriers to use, and ideas for future AFO design. STUDY DESIGN: Secondary qualitative data analysis. METHODS: Secondary data analysis was performed on semistructured focus groups that included 68 individuals with CP and 74 caregivers. Of the focus group participants, 66 mentioned AFOs (16 individuals with CP and 50 caregivers). Deidentified transcripts were analyzed using inductive coding, and the codes were consolidated into themes. RESULTS: Four themes emerged: 1) AFO provision is a confusing and lengthy process, 2) participants want more information during AFO provision, 3) AFOs are uncomfortable and difficult to use, and 4) AFOs can benefit mobility and independence. Caregivers and individuals with CP recommended ideas such as 3D printing orthoses and education for caregivers on design choices to improve AFO design and provision. CONCLUSIONS: Individuals with CP and their caregivers found the AFO provision process frustrating but highlight that AFOs support mobility and participation. Further opportunities exist to support function and participation of people with CP by streamlining AFO provision processes, creating educational materials, and improving AFO design for comfort and ease of use.

Infusing disability equity within rehabilitation education and practice: A qualitative study of lived experiences of ableism, allyship, and healthcare partnership.

Background: Addressing issues of diversity, equity, and inclusion (DEI) has become central in implementing inclusive and socially responsible rehabilitation education and clinical practice. Yet, the constructs of disability and d/Deaf identity and culture, as well as ableism and allyship are often overlooked. Or, these concepts are approached using outdated philosophical perspectives that pathologize disability and fail to prioritize the lived experiences, expertise, intersectionality, and self-identified needs of people with disabilities. A Critical Disability Studies (CDS) framework may provide a background for better understanding and responding to these issues through allyship. Purpose: This study employed a CDS framework to understand the lived experiences of ableism and allyship from faculty, staff, and students on University of Washington (UW) campuses who identify as d/Deaf, disabled/with a disability, or as having a chronic health condition. Methods: During 2020-2021, we conducted in-depth, semi-structured interviews and focus groups with 22 diverse undergraduate and graduate students, faculty, and staff with disabilities, one third who also identified as people of color. Encounters were audio-recorded, transcribed verbatim, and coded using constant comparison until themes emerged. Results: Four major themes that emerged from the data are: (1) Ever-present ableism in healthcare, (2) Ableism at the intersections, (3) COVID: Surfacing ableism and expanding access, and (4) Disability allyship and healthcare partnership building. Experiences of ableism and allyship were identified at individual, group/unit, and institutional/systemic levels, though participants reported significantly fewer instances of allyship compared to experiences of ableism. Participants identified intersections between disability and other marginalized identities and juxtaposed the benefits of widespread adoption of many access-increasing practices and technologies due to the COVID-19 pandemic, while also highlighting ways in which the pandemic created new obstacles to inclusion. Conclusions: This analysis provides insights into ways of implementing inclusive practices in rehabilitation education, practice, and beyond. Rehabilitation students, faculty, and staff may not be aware of how ableism affects their disabled peers or underpins their professional education. It is important to cultivate opportunities within professional education and clinical training to explicitly address our collective role in creating inclusive and accessible academic and healthcare experiences for our diverse community post COVID-19. Drawing on a CDS framework, the research team devised the mnemonic TRAC, which includes Training, Recognition and Representation, Attendance and Action, and Calling to account as strategic guidelines for operationalizing such opportunities.

In the Driver's Seat: A Randomized, Crossover Clinical Trial Protocol Comparing Home and Community Use of the Permobil Explorer Mini and a Modified Ride-On Car by Children With Cerebral Palsy.

OBJECTIVE: The aims of this study are 2-fold: (1) to evaluate a powered mobility intervention to promote developmental, activity, and participation outcomes of young children aged 12 to 36 months who have cerebral palsy; and (2) to compare the use patterns (frequency, duration, environment) of 2 different powered mobility options. METHODS: This study is a multisite, mixed-methods, doubly counterbalanced, randomized, crossover clinical trial, where intervention A is the Permobil Explorer Mini and intervention B is a modified ride-on toy car. The study will take place in rural and urban home and community settings surrounding 3 sites (Washington, Oregon, and Michigan). There will be 24 child-caregiver dyads in the study (8 dyads per site). Primary outcome measures include the Bayley Scale of Infant and Toddler Development, the Youth and Children's Participation and Environment Measure, the Assessment for Learning Power mobility use, automated device use tracking logs, caregiver semistructured interviews, and the Acceptability, Feasibility, and Intervention Appropriateness Measures. Secondary measures include the Child Engagement in Daily Life and caregiver diaries. IMPACT: The use of powered mobility devices for young children with cerebral palsy has gained traction, with evidence that the use of powered mobility at young ages complements (rather than detracts from) other interventions focused on more traditional mobility skills such as crawling and walking. However, research is limited, and often comprised of low-level evidence. Given the clearance of the first powered mobility device for infants, the Permobil Explorer Mini, and the recent popularity of modified ride-on toy cars as an alternative for powered mobility for young children with disabilities, this study will contribute to rigorous examination of the developmental outcomes, use patterns, and caregiver perceptions of these novel devices.

Understanding Acceptability, Barriers, and Facilitators to Clinical Implementation of the on Track Developmental Monitoring System for Children with Cerebral Palsy: A Qualitative Study.

AIMS: On Track Developmental Monitoring System (DMS) is a novel series of tools to assist in shared-decision making, guide rehabilitation intervention based on functional ability levels, and promote episodic care service models. Further understanding of the acceptability, feasibility, and appropriateness of On Track DMS in clinical settings is critical. The purpose of this study was to understand clinician perspectives of the acceptability of On Track DMS and to identify potential implementation barriers and facilitators within pediatric physical therapist practice. METHODS: Three, day-long training workshops were conducted with 32 pediatric physical therapists across the US. Focus groups with 21 workshop participants were conducted following training. Results were audio recorded, transcribed verbatim, and coded into themes. RESULTS: Three themes emerged from the data: (1) Valuing the On Track Approach to Intervention; (2) Setting-Specific Needs and Challenges to Implementation; and (3) Training Material/Tool Strengths and Limitations. CONCLUSIONS: On Track DMS appears to have initial value and acceptability for pediatric physical therapists across practice settings. Perceived benefits include facilitation of data-driven practice and therapist/family collaboration to improve health outcomes for children with CP. Using this data to understand and assess barriers and facilitators to knowledge use are first steps in successfully implementing On Track DMS.

Supportive mobility device use across the life span by individuals with cerebral palsy: A qualitative study.

AIM: To understand the mobility experiences, supportive mobility device (SMD) use, and desired participation outcomes of individuals with cerebral palsy (CP) across the life span, and describe how perspectives of rehabilitation care and professional resources may influence mobility decision-making processes and outcomes. METHOD: In the second phase of an overarching study, focus groups were conducted with 164 participants (68 individuals with CP; 32 females, 36 males; mean age 17y 8mo, SD 11y 11mo, range 3-68y), 74 caregivers (50 females, 24 males), and 22 healthcare providers (14 females, eight males) across four US cities. Sessions were audio-recorded, transcribed, and analysed using constant comparison. RESULTS: Six themes emerged. Five presented across all stakeholder groups: (1) the system is broken; (2) equipment is simultaneously liberating and restricting; (3) adaptation across the life span; (4) designed for transport, not for living; and (5) sharing our stories and sharing resources. One theme (theme 6) was specific to healthcare providers: caught in the middle. INTERPRETATION: This qualitative study underscores the simultaneous value and frustration associated with SMDs as described by the community with CP, and recognition among all stakeholders of the need to improve connections and resource networks within the community with CP to improve SMD design and provision processes across device types and across the life span for individuals with CP. WHAT THIS PAPER ADDS: Supportive mobility devices (SMDs) were most often equated with freedom, participation, and independence. Frustration with SMDs across the life span persisted with regard to design, function, cost, and maintenance. Stakeholders in the community with cerebral palsy are seeking greater networking and resource sharing to enhance SMD provision processes. Access to appropriate SMDs across the life span and the need for system improvement are critical.

OBJETIVO: Compreender as experiências de mobilidade, o uso de dispositivos de mobilidade de apoio e os resultados de participação desejados de pessoas com paralisia cerebral (PC) ao longo da vida e descrever como as perspectivas de cuidados de reabilitação e recursos profissionais podem influenciar os processos de tomada de decisão de mobilidade e resultados. MÉTODO: Na segunda fase de um estudo abrangente, foram realizados grupos focais com 164 participantes (68 pessoas com PC; 32 mulheres, 36 homens; idade média de 17 anos e 8 meses, DP 11 anos e 11 meses, faixa de 3 a 68 anos), 74 cuidadores (50 mulheres, 24 homens) e 22 profissionais de saúde (14 mulheres, oito homens) em quatro cidades dos EUA. As sessões foram gravadas em áudio, transcritas e analisadas por meio de comparação constante. RESULTADOS: Emergiram seis temas. Cinco apresentados em todos os grupos de partes interessadas: (1) o sistema está quebrado; (2) o equipamento está simultaneamente liberando e restringindo; (3) adaptação ao longo da vida; (4) projetado para transporte, não para a vida; e (5) compartilhar nossas histórias e recursos. Um tema (tema 6) era específico para os profissionais de saúde: "pego no meio". INTERPRETAÇÃO: Este estudo qualitativo ressalta o valor e a frustração simultâneos associados aos dispositivos de mobilidade de apoio, conforme descrito pela comunidade com CP, e o reconhecimento entre todas as partes interessadas da necessidade de melhorar as conexões e redes de recursos dentro da comunidade com CP para melhorar os processos de projeto e fornecimento de SMD em todos os dispositivos tipos e ao longo da vida para pessoas com PC.

Item development, internal consistency, and known-groups validity of the Self-Directed Mobility Scale.

PURPOSE: The aims of the current study include to: (1) describe the item development; and (2) begin the process of establishing the internal consistency and known-groups validity of the Self-Directed Mobility Scale. The purpose of the scale is to assess paediatric physical and occupational therapists' views towards self-directed mobility and their perceived ability and intentions to advocate for children's access to self-directed mobility. METHODS: Three individuals with expertise in kinesiology, psychology, paediatric rehabilitation, and disability studies served as the expert panel for item development. Four samples were included to determine internal consistency and known-groups validity: 350 physical therapists, 89 occupational therapists, 279 kinesiology undergraduate students, and 528 health and wellness undergraduate students. RESULTS: The internal consistency was above the acceptable level of 0.70 (range = 0.72-0.77) for all samples when two items regarding promoting other motor skills prior to powered mobility use and the temporary use of a mobility device were removed. Known-groups validity was established between all samples. CONCLUSIONS: The Self-Directed Mobility Scale appears to be a valid tool for assessing views of self-directed mobility and mobility advocacy intentions in paediatric physical and occupational therapists, as well as undergraduate students. Future work should examine the internal consistency based on study sample to ensure the (> 0.70) acceptable Cronbach's alpha level is met.Implications for rehabilitationThe Self-Directed Mobility Scale is a viable measurement tool to assess views of self-directed mobility and mobility advocacy intentions of pediatric physical and occupational therapists.In combination with other measures, the Self-Directed Mobility Scale may be used in future rehabilitation research to evaluate factors associated with provision of mobility technology to children with disabilities.

Explicit and implicit disability attitudes of occupational and physical therapy assistants.

BACKGROUND: Reduction of explicit and implicit bias in healthcare providers is a critical issue faced by our society in moving toward more equitable and culturally appropriate health and rehabilitation care. Because resources for OT and PT services are limited and shortages in these professions exist, direct care provision by occupational and physical therapist assistants (OTA/PTA) is on the rise and valued in comprehensive rehabilitation practice. It is important to consider attitudes and biases of OTA/PTA, as they are directly involved in provision of rehabilitation services for people with disabilities. OBJECTIVE: This study examined the explicit and implicit disability attitudes of a large cross-section of OTA/PTA. METHODS: Secondary data analysis was completed using data from 6113 OTA/PTA from the Project Implicit Disability Attitudes Implicit Association Test. Implicit attitudes were calculated and OTA/PTA explicit and implicit disability attitudes were compared. Results were further categorized using an adapted version of Son Hing et al.'s two-dimensional model of prejudice. RESULTS: Findings revealed the majority of OTA/PTA reported having no explicit preference for people with disabilities or nondisabled people. However, the majority of OTA/PTA were aversive ableists, indicating low explicit and high implicit bias. CONCLUSIONS: Though explicit bias is lower in OTA/PTA, implicit bias is strong, indicating that people with disabilities face bias that may influence clinical interactions, and may be reproduced in professional education, practice, and policy. Concrete action must be taken to recognize and address disability bias to reduce health disparities in people with disabilities.

Clinical Use of Surface Electromyography to Track Acute Upper Extremity Muscle Recovery after Stroke: A Descriptive Case Study of a Single Patient.

Arm recovery varies greatly among stroke survivors. Wearable surface electromyography (sEMG) sensors have been used to track recovery in research; however, sEMG is rarely used within acute and subacute clinical settings. The purpose of this case study was to describe the use of wireless sEMG sensors to examine changes in muscle activity during acute and subacute phases of stroke recovery, and understand the participant's perceptions of sEMG monitoring. Beginning three days post-stroke, one stroke survivor wore five wireless sEMG sensors on his involved arm for three to four hours, every one to three days. Muscle activity was tracked during routine care in the acute setting through discharge from inpatient rehabilitation. Three- and eight-month follow-up sessions were completed in the community. Activity logs were completed each session, and a semi-structured interview occurred at the final session. The longitudinal monitoring of muscle and movement recovery in the clinic and community was feasible using sEMG sensors. The participant and medical team felt monitoring was unobtrusive, interesting, and motivating for recovery, but desired greater in-session feedback to inform rehabilitation. While barriers in equipment and signal quality still exist, capitalizing on wearable sensing technology in the clinic holds promise for enabling personalized stroke recovery.

Electromyography Recordings Detect Muscle Activity Before Observable Contractions in Acute Stroke Care.

OBJECTIVE: To evaluate muscle activity in the arms of adult stroke survivors with limited or no arm movement during acute care. DESIGN: Prospective observational study. SETTING: Acute care regional stroke center. PARTICIPANTS: We recruited adults (N=21) who had a stroke within the previous 5 days who were admitted to a level 1 trauma hospital and had a National Institutes of Health Stroke Scale score >1 for arm function at the time of recruitment. A total of 21 adults (13 men, 8 women) with an average age of 60±15 years were recruited an average of 3±1 days after their stroke. Eleven (7 men, 4 women; age, 56±11y) had no observable or palpable arm muscle activity (Manual Muscle Test [MMT]=0) and 10 (6 men, 4 women; age, 64±1y) had detectable activity (MMT>0). INTERVENTIONS: Dual mode sensors (electromyography and accelerometry) were placed on the anterior deltoid, biceps, triceps, wrist extensors, and wrist flexors of the impaired arm. MAIN OUTCOME MEASURES: The number of muscle contractions, as well as average duration, amplitude, and co-contraction patterns were evaluated for each participant. RESULTS: Muscle contractions were observed in all 5 muscles for all participants using electromyography (EMG) recordings. Contractions were easily identified from 30 minutes of monitoring for participants with an MMT >0, but up to 3 hours of monitoring was required for participants with an MMT=0 to detect contractions in all 5 muscles during standard care. Only the wrist extensors demonstrated significantly larger amplitude contractions for participants with an MMT>0 than those with an MMT=0. Co-contraction was rare, involving less than 10% of contractions. Co-contraction of 2 muscles most commonly aligned with the flexor synergy pattern commonly observed after stroke. For participants with an MMT=0, the number of contractions and maximum amplitude were moderately correlated with MMT scores at follow-up. CONCLUSIONS: Muscle activity was detected with surface EMG recordings during standard acute care, even for individuals with no observable activity by clinical examination. Wearable sensors may be useful for monitoring early muscle activity and movement after stroke.

Evaluation of a passive pediatric leg exoskeleton during gait.

BACKGROUND: Children with hemiparesis are commonly prescribed ankle foot orthoses to help improve gait; however, these orthoses often result in only small and variable changes in gait. Research with adult stroke survivors has suggested that orthoses that extend beyond the ankle using long, passive tendon-like structures (i.e. exotendons) can improve walking. OBJECTIVES: The aim of this study was to quantify the impact of an exotendon-based exoskeleton on pediatric gait. STUDY DESIGN: Repeated-measures study. METHODS: Two typically-developing children and two children with hemiparesis completed a gait analysis, walking without and with the exoskeleton. The exotendon was tested at three stiffness levels. RESULTS: All children were able to walk comfortably with the exoskeleton, with minimal changes in step width. Walking speed increased and lower limb joint symmetry improved for the children with hemiparesis with the exoskeleton. Each participant had changes in muscle activity while walking with the exoskeleton, although the impact on specific muscles and response to exotendon stiffness varied. CONCLUSION: Exotendon-based exoskeletons may provide an alternative solution for optimizing gait in therapy and in the community for children with hemiparesis. Determining the optimal stiffness and configuration for each child is an important area of future research.

Muscle Activity After Stroke: Perspectives on Deploying Surface Electromyography in Acute Care.

After a stroke, clinicians and patients struggle to determine if and when muscle activity and movement will return. Surface electromyography (EMG) provides a non-invasive window into the nervous system that can be used to monitor muscle activity, but is rarely used in acute care. In this perspective paper, we share our experiences deploying EMG in the clinic to monitor stroke survivors. Our experiences have demonstrated that deploying EMG in acute care is both feasible and useful. We found that current technology can be used to comfortably and non-obtrusively monitor muscle activity, even for patients with no detectable muscle activity by traditional clinical assessments. Monitoring with EMG may help clinicians quantify muscle activity, track recovery, and inform rehabilitation. With further research, we perceive opportunities in using EMG to inform prognosis, enable biofeedback training, and provide metrics necessary for supporting and justifying care. To leverage these opportunities, we have identified important technical challenges and clinical barriers that need to be addressed. Affordable wireless EMG system that can provide high-quality data with comfortable, secure interfaces that can be worn for extended periods are needed. Data from these systems need to be quickly and automatically processed to create round-ready results that can be easily interpreted and used by the clinical team. We believe these challenges can be addressed by integrating and improving current methods and technology. Deploying EMG in the clinic can open new pathways to understanding and improving muscle activity and recovery for individuals with neurologic injury in acute care and beyond.

"It's All Sort of Cool and Interesting but What Do I Do With It?" A Qualitative Study of Stroke Survivors' Perceptions of Surface Electromyography.

Background: Stroke is one of the most common neurologic injuries worldwide. Over decades, evidence-based neurorehabilitation research and advancements in wireless, wearable sensor design have supported the deployment of technologies to facilitate recovery after stroke. Surface electromyography (sEMG) is one such technology, however, clinical application remains limited. To understand this translational practice gap and improve clinical uptake, it is essential to include stakeholder voices in an analysis of neurorehabilitation practice, the acceptability of current sEMG technologies, and facilitators and barriers to sEMG use in the clinic and the community. The purpose of this study was to foreground the perspectives of stroke survivors to gain a better understanding of their experiences in neurorehabilitation, the technologies they have used during their recovery, and their opinions of lab-designed and commercially-available sEMG systems. Methods: A qualitative, phenomenological study was completed. In-depth, semi-structured interviews were conducted with eight stroke survivors (age range 49-78 years, 6 months to 12 years post-stroke) and two caregivers from a large metropolitan region. A demonstration of four sEMG systems was provided to gather perceptions of sensor design, features and function, and user interface. Interviews were audio-recorded, transcribed verbatim, and coded for analysis using constant comparison until data saturation was reached. Results: Three themes emerged from the data: (1) "Surface EMG has potential….but…" highlights the recognition of sEMG as a valuable tool but reveals a lack of understanding and need for clear meaning from the data; (2) "Tracking incremental progress over days or years is important" highlights the persistence of hope and potential benefit of sEMG in detecting small changes that may inform neurorehabilitation practice and policy; and (3) "Neurorehabilitation technology is cumbersome" highlights the tension between optimizing therapy time and trying new technologies, managing cost, logistics and set-up, and desired technology features. Conclusion: Further translation of sEMG technology for neurorehabilitation holds promise for stroke survivors, but sEMG system design and user interface needs refinement. The process of using sEMG technology and products must be simple and provide meaningful insight to recovery. Including stroke survivors directly in translational efforts is essential to improve uptake in clinical environments.
