An Evaluation of a Clinic-Based Low Vision Device Lending Library.

As the efficacy of low vision service provision is facilitated by clients' access to and proper use of low vision devices, the objective of this study was to evaluate an outpatient clinic-based low vision device lending library program and the functional and psychosocial impact that device use had upon clients. Twenty individuals borrowed portable video magnifiers during the study period. Line items from the Revised-Self-Report Assessment of Functional Visual Performance and the Reading Behavior Inventory were analyzed before and after device loan at two months. The Psychosocial Impact of Assistive Devices Scale-10 and a semi-structured interview were also completed at two months. Reported improvements in reading performance and satisfaction levels on the Reading Behavior Inventory were significant (p<.001). The Revised-Self-Report Assessment of Functional Visual Performance indicated improved independence in reading medications, bills and labels. Higher scores in happiness, independence, sense of control and adaptability on the Psychosocial Impact of Assistive Devices Scale-10 indicated device retention at two months. Qualitative themes included improved independence, time needed to acclimate to the device, personal appraisal impacting motivation and challenges specific to low vision. This article provides occupational therapists a model to facilitate access, person-device fit and successful use of low vision devices to promote therapy outcomes.

On the way home: a BCI-FES hand therapy self-managed by sub-acute SCI participants and their caregivers: a usability study.

BACKGROUND: Regaining hand function is the top priority for people with tetraplegia, however access to specialised therapy outwith clinics is limited. Here we present a system for hand therapy based on brain-computer interface (BCI) which uses a consumer grade electroencephalography (EEG) device combined with functional electrical stimulation (FES), and evaluate its usability among occupational therapists (OTs) and people with spinal cord injury (SCI) and their family members. METHODS: Users: Eight people with sub-acute SCI (6 M, 2F, age 55.4 ± 15.6) and their caregivers (3 M, 5F, age 45.3 ± 14.3); four OTs (4F, age 42.3 ± 9.8). User Activity: Researchers trained OTs; OTs subsequently taught caregivers to set up the system for the people with SCI to perform hand therapy. Hand therapy consisted of attempted movement (AM) of one hand to lower the power of EEG sensory-motor rhythm in the 8-12 Hz band and thereby activate FES which induced wrist flexion and extension. Technology: Consumer grade wearable EEG, multichannel FES, custom made BCI application. LOCATION: Research space within hospital. Evaluation: donning times, BCI accuracy, BCI and FES parameter repeatability, questionnaires, focus groups and interviews. RESULTS: Effectiveness: The BCI accuracy was 70-90%. Efficiency: Median donning times decreased from 40.5 min for initial session to 27 min during last training session (N = 7), dropping to 14 min on the last self-managed session (N = 3). BCI and FES parameters were stable from session to session. Satisfaction: Mean satisfaction with the system among SCI users and caregivers was 3.68 ± 0.81 (max 5) as measured by QUEST questionnaire. Main facilitators for implementing BCI-FES technology were "seeing hand moving", "doing something useful for the loved ones", good level of computer literacy (people with SCI and caregivers), "active engagement in therapy" (OT), while main barriers were technical complexity of setup (all groups) and "lack of clinical evidence" (OT). CONCLUSION: BCI-FES has potential to be used as at home hand therapy by people with SCI or stroke, provided it is easy to use and support is provided. Transfer of knowledge of operating BCI is possible from researchers to therapists to users and caregivers.

Can occupational therapy manpower be replaced with social robots in a singing group during COVID-19?

BACKGROUND: Prior to the COVID-19 global health emergency, reducing direct contacts between therapists and patients is an important issue, and could be achieved by using robots to perform certain caring activities. OBJECTIVE: This study compares therapeutic factors of singing group activities directed by social robots and by occupational therapists at elderly care centers during this COVID-19 outbreak. METHODS: This project has a quasi-experimental research design, based on a pilot study of 14 subjects aged above 65 years. They received eight sessions of singing group therapy given by a social robot or an occupational therapist. Completed copies of a therapeutic-factor questionnaire were then collected. RESULTS: At the 4th week, the scores for 8 therapeutic factors were higher in sessions with the occupational therapist than the robot-directed sessions, reaching a statistically significant level; at the 8th week, the scores for 3 therapeutic factors, including imparting of information, were higher in sessions with the occupational therapist than in sessions with the robot. The top scoring therapeutic factor in the robot sessions was group cohesiveness. CONCLUSIONS: Social robots may be good companion tools for elderly care during this COVID-19 outbreak, but group therapy sessions supervised by real-person therapists still have higher therapeutic factor scores than those conducted by robots. The number of subjects needs to be increased to enhance the validity of future study results.

The fourier M2 robotic machine combined with occupational therapy on post-stroke upper limb function and independence-related quality of life: A randomized clinical trial.

Most post-stroke patients experience upper limb functionality challenges. Emergent therapies using upper limb-based robot machines present opportunities to resolve the limitations inherent in Occupational therapy such as increased therapist-patient exhaustion, monotonous methods, and so forth. The aim of this parallel trial was to compare the effects of the upper limb robotic training with matched Occupational therapy training on upper limb function and independence-related quality of life in post-stroke patients within the Brunnstrom arm motor recovery stages 1 to 4. During one-year (2018-2019), 50 post-stroke patients were enrolled and randomly assigned to 2 groups; robot and Occupational therapy (n = 25) and Occupational therapy (n = 25). Both groups were trained for 50-70 minutes per day, 5 days a week for 6 weeks. The Chinese-adapted Fugl-Meyer Assessment-Upper Extremity (FMA-UE) was the primary outcome measure. The secondary outcome measures were the Brunnstrom Recovery Stages Scale (BRS) and the Chinese-adapted Barthel Index (BI). The treatment effect sizes of both groups were large in the following variables; transfers (1), BI total score (2.2), FMA-UE upper limb (1.1), wrist (1.8), elbow (1), fingers (0.9), and FMA-UE total scores (1.4). The treatment group in comparison to the control group had larger BRS changes, significant improvements in upper limb function, and partial independence in activities of daily living during the baseline to post-treatment period. Robotic-assisted training with occupational therapy may improve the upper limb movement foundation blocks; however, it does not translate into complete functional independence and improved quality of life. This study has been registered at the ISRCTN registry, https://doi.org/10.1186/ISRCTN84804731.

Was a global pandemic needed to adopt the use of telehealth in occupational therapy?

BACKGROUND: An analysis of data from an international survey was undertaken to determine the impact of the COVID-19 pandemic on telehealth practice in occupational therapy worldwide, in addition to facilitators and barriers in utilising this form of service delivery. METHOD: The global online survey was circulated in the occupational therapy community by the World Federation of Occupational Therapists (WFOT) between April and July 2020, collecting responses to closed-ended questions, in addition to free-text comments. Descriptive statistics and bivariate analyses were used to assess relationships between respondent characteristics and the utilisation of telehealth. Thematic statement analysis provided further insight regarding factors impacting telehealth use. RESULTS: Findings revealed a significant increase in the use of telehealth strategies with the onset of the pandemic among survey respondents, with many reported benefits. Bivariate analyses indicated telehealth users were more likely to score higher feelings of safety and positive work morale, as well as perceive employer expectations to be reasonable. Restricted access to technology, limitations of remote practice, funding issues and slow pace of change were identified as barriers for some respondents to utilising telehealth. Facilitators included availability of supportive policy, guidelines and strategies, in addition to education and training. CONCLUSION: This study advances the understanding of the current scope of occupational therapy telehealth practice in the context of the ongoing COVID-19 pandemic. Although results suggest long-term potential for telehealth use as an adjunct to traditional service provision, important considerations were identified regarding factors influencing integration of such strategies.

OBJECTIVE: We aimed to analyze the use of virtual reality among occupational therapists working with neurological patients. Methods. A descriptive cross-sectional study was conducted on occupational therapists working in neurorehabilitation centers in the Alicante province between February and May 2017. The information was collected using an online questionnaire made up of 36 questions. RESULTS: Of the 23 participants, the majority of them were women (82.6%) with an average age of 31.4 years (SD: 4.1). Approximately half of them (52.2%) used virtual reality as a treatment tool, mainly with adults aged 46-65 (75.0%) affected by acquired brain damage (75.0%) and with cognitive alterations (91.7%). The intervention areas targeted were: attention (83.3%), vision (75.0%), upper limb mobility (75.0%), verbal communication (66.7%), eating (50.0%), shopping (41.7%), and social participation with friends (41.7%). The most used virtual reality systems in occupational therapy treatments were the NeuronUp platform (50.0%) and Xbox Kinect (R) / Nintendo Wii (R) (33.3%) used with a computer or a tablet. CONCLUSIONS: Only half of the occupational therapists in the study used virtual reality as a complementary tool for conventional treatment. Further studies exploring the use of these techniques in occupational therapy with people affected by neurological conditions are required

Impact of smart force feedback rehabilitation robot training on upper limb motor function in the subacute stage of stroke.

OBJECTIVE: To explore the impact of rehabilitation robot training (RRT) on upper limb motor function and daily activity ability in patients with stroke. METHODS: Forty patients meeting the inclusion criteria were randomly divided into the treatment group (TRE) and the control group (CON). Group TRE was trained with an upper limb rehabilitation robot and group CON was trained with traditional occupational therapy. The training time was six weeks, and the upper limb function and daily activities were then assessed. RESULTS: (1) There was no statistical significance in the Fugl-Meyer (FM) score, Wolf Motor Function Test (WMFT) score, and Modified Barthel Index (MBI) score between the two groups before treatment (P > 0.05). (2) After treatment, the FM score, WMFT score, and MBI score were significantly higher than before treatment (P < 0.01). (3) There was no significant significance between the two groups after treatment (P > 0.05). CONCLUSIONS: Both RRT and traditional occupational therapy training are useful for the recovery of upper limb motor function and daily life ability in the sub-acute stage of stroke.

The use of safe patient handling and mobility equipment in rehabilitation.

BACKGROUND: Increasingly, occupational and physical therapists are using safe patient handling and mobility (SPHM) equipment, such as mechanical lifts, in rehabilitation. However, there is little guidance in the literature on how SPHM equipment can be used to assist patients to reach rehabilitation goals. The purpose of this projectwas to document and categorize common and innovative ways rehabilitation therapists use SPHM equipment in their clinical practice. OBJECTIVE: This article investigates common and innovative uses of SPHM equipment in rehabilitation practice. METHODS: Occupational, physical and kinesio therapist employed at the Veterans Health Administration wrote narratives and took photos describing rehabilitation therapy activities where they used SPHM equipment in their clinical practice. The authors used a systematic process to review and categorize the narratives and subsequent photos by using the World Health Organization's International Classification of Functioning, Disability and Health (ICF). RESULTS: Thirty narratives (13 innovative and 17 common) were coded into four categories on the ICF section of mobility. The most common category was "changing and maintaining basic body position"(21) followed by "walking and moving" (5). The category "carrying, moving and handling objects" garnered two narratives and there were no narratives for "using transportation." CONCLUSIONS: Project findings may serve as a guide for therapists who would like to enhance their use of SPHM equipment in rehabilitation. Additional research is needed to expand the use of SPHM in rehabilitation practice and evaluate the impact on patient rehabilitation outcomes and therapist safety outcomes.

Adaptive Eating Device: Performance and Satisfaction of a Person with Parkinson's Disease.

BACKGROUND.: Individuals with Parkinson's disease (PD) can experience motor impairments related to their hand-use that restrict participation in daily activities. Feeding is one activity impacted by this health condition. The use of adapted utensils can improve performance and independence in this activity. PURPOSE.: To investigate if a locally designed and made eating-adaptive device helps a person with PD to improve their feeding performance. METHOD.: Single-case ABC-type experimental design. Performance and satisfaction of a 60-year-old man with PD were assessed during feeding tasks in 70 sequential days in three phases. Celeration Line, Two-Standard Deviation Band, and Visual Analysis were the methods used for data analysis. FINDINGS.: Performance and satisfaction increased significantly after the introduction of the adaptive eating device. The addition of weight also contributed to the increase in the participant's performance. IMPLICATIONS.: Adaptive eating device with low production costs and possibility of customized adjustments improves performance of people with PD.

Design and development of a sensored glove for home-based rehabilitation.

STUDY DESIGN: Descriptive. INTRODUCTION: Rehabilitation programs that focus on motor recovery of the upper limb require long-term commitment from the clinicians/therapists, require one-to-one caring, and are usually labor-intensive. PURPOSE OF THE STUDY: To contribute to this area, we have developed a sensored hand glove integrated with a computer game (Flappy Bird) to engage patients playing a game where the subject's single/multiple fingers are involved, representing fine motor skill occupational therapeutic exercises. METHODS: We described the sensored rehab glove, its hardware design, electrical and electronic design and instrumentation, software design, and pilot testing results. RESULTS: Experimental results supported that the developed rehab glove system can be effectively used to engage a patient playing a computer game (or a mobile phone game) that can record the data (ie, game score, finger flexion/extension angle, time spent in a therapeutic session, etc.) and put it in a format that could be easily read by a therapist or displayed to the therapists/patients in different graph formats. CONCLUSIONS: We introduced a sensored rehab glove for home-based therapy. The exercise training using the glove is repetitious, functional, and easy to follow and comply with.

Effects of pressure garment on spasticity and function of the arm in the early stages after stroke: a randomized controlled trial.

OBJECTIVE: To investigate the effects of pressure (Lycra) garment on the spasticity and function of the arm in the early stages after stroke. DESIGN: A randomized controlled trial. SETTING: Occupational therapy unit of a public hospital. SUBJECTS: A total of 46 adults with stroke. INTERVENTION: After random assignment, for six weeks, both intervention group and control group received a 2 hour/week conventional occupational therapy program, with the intervention group receiving an extra 6 hour/day pressure garment application (long glove). MAIN MEASURES: Modified Modified Ashworth Scale, Disabilities of Arm, Shoulder and Hand Outcome Measure, and Jebsen-Taylor Hand Function Test. Eligibility measures: Mini Mental State Examination and Modified Modified Ashworth Scale. Assessments were performed at baseline and six weeks postintervention. RESULTS: There were 21 participants with the mean age of 51.19 (8.28) years in the intervention group and 22 participants with the mean (SD) age of 52.82 (8.71) years in the control group. The intervention group had median (interquartile range (IQR)) post-stroke duration of 1 (1) month, while for the control group, they were 2 (2) months. There was no difference in spasticity, and both perceived and actual arm functions between the groups at six weeks after baseline. CONCLUSION: Wearing a pressure garment on the arm for 6 hours daily had no effect in controlling spasticity or on improving arm function in the early stages after stroke.

Enhancing function after radial nerve injury with a high-profile orthosis and a bio-occupational orthotic framework.

STUDY DESIGN: Case report. INTRODUCTION: Radial nerve injury can cause severe functional impairment due to paralysis of wrist and digit extensors. Various orthotic designs have been described, including static, dynamic, and tenodesis. All provide wrist stabilization or extension assistance. Some, but not all, also provide extension assistance to the wrist, thumb, and fingers. PURPOSE AND METHODS: This article tells the story of Max, a 27-year-old male university student, who sustained a radial nerve injury after a left humeral shaft fracture. He was treated at a Brazilian tertiary hospital, where the choice of thermoplastics and dynamic components resulted in limited options for orthotic fabrication. Max was provided with custom-molded static wrist orthosis and a bulky, older style, high-profile dynamic forearm-based wrist-finger-thumb assistive-extension orthosis. RESULTS AND DISCUSSION: Grip strength and functional status improved, and Max was completely satisfied because with the dynamic orthosis, he could play the guitar again, which was his favorite activity. CONCLUSION: Max's story illustrates that a convenient functionally oriented orthotic intervention can be performed even in resource-limited environments by following the client-centered bio-occupational orthotic framework proposed by McKee and Rivard. This framework addresses the client's biological needs (addressing paralyzed muscles and maintaining length of soft tissues) and occupational/functional needs.

Clinical Utility of the Canadian Occupational Performance Measure in Older Adult Rehabilitation and Nursing Homes: Perceptions among Occupational Therapists and Physiotherapists in Spain.

INTRODUCTION: Scientific evidence that supports the psychometric properties of the COPM as a tool to enable personalized care has been repeatedly shown. However, there is a lack of studies about its utility within the Spanish research community. AIM: This qualitative study seeks to ascertain the perceptions of professionals from social health centers, nursing homes, and Spanish rehabilitation services about the clinical utility of the COPM as a standardized instrument. METHODS: Thirty occupational therapists and physiotherapists in four focus groups discussed the experience of applying the COPM. The interpretative phenomenological analysis (IPA) incorporated a multidimensional model of clinical utility based on the components of acceptable, appropriate, accessible, and practicable by the clients, professionals, and institutions. Results and Discussion. The results of the utility study showed that the COPM helped professionals and clients to gain significant involvement in the treatment process. The COPM contributed to the process of further goal setting, occupation-based, and client-centered, thus achieving considerable satisfaction from the clients that had treatment. The professional training and adaptation to the geriatric population were vital to this process. CONCLUSION: The COPM is a useful and viable tool for the institutions that are supportive of a client-centered approach in the Spanish context.

Does occupational therapy delay or reduce the proportion of patients that receives thumb carpometacarpal joint surgery? A multicentre randomised controlled trial.

Objectives: To evaluate whether occupational therapy, provided in the period between referral and surgical consultation, might delay or reduce the need of surgery in thumb carpometacarpal joint (CMCJ) osteoarthritis and to explore predictors for CMCJ surgery. Methods: This multicentre randomised controlled trial included patients referred for surgical consultation due to CMCJ osteoarthritis. An occupational therapy group received hand osteoarthritis education, assistive devices, CMCJ orthoses and exercises. A control group received only hand osteoarthritis information. Primary outcome was the proportion of patients that had received CMCJ surgery after 2 years. We examined the primary outcome and predictors for surgery with regression models, and time to surgery with the log-rank test and cox regression analyses. Results: Of 221 patients screened for eligibility, 180 were randomised. Information on the primary outcome was collected from medical records for all included patients. Surgery was performed on 22 patients (24%) that had received occupational therapy and 29 (32%) control patients (OR 0.56, 95% CI 0.26 to 1.21; p=0.14). Median time to surgery was 350 days (IQR 210-540) in the occupational therapy group and 296 days (IQR 188-428) in the control group (p=0.13). Previous non-pharmacological treatment (OR 2.72, 95% CI 1.14 to 6.50) and higher motivation for surgery (OR 1.25, 95% CI 1.09 to 1.43) were significant predictors for CMCJ surgery. Conclusions: Occupational therapy showed a small non-significant tendency to delay and reduce the need for surgery in CMCJ osteoarthritis. Previous non-pharmacological treatment and higher motivation for surgery were significant predictors for surgery.

Construct validity, test-retest reliability, and the ability to detect change of the Canadian Occupational Performance Measure in a spinal cord injury population.

Study design: Cross-sectional study. Objectives: To examine the construct validity and the ability to detect change, of the Italian version of the Canadian Occupational Performance Measure (COPM) in a spinal cord injury (SCI) population. Settings: Rehabilitation service of the Paraplegic Center of Ostia, Italy. Methods: Thirty-nine spinal cord injury participants were recruited. The clinimetric properties of the measure were assessed following international guidelines. Cronbach's alpha and the intraclass correlation coefficient were assessed for internal consistency and test-retest reliability, respectively. Construct validity was evaluated, by calculating correlation between COPM and the Spinal Cord Independence Measure (SCIM) through Pearson's correlation coefficient and Spearman's Rho. The ability to detect change was evaluated on the overall sample. Results: The COPM was shown to be reliable in a spinal cord injury sample with positive and statistically significant results for Cronbach's alpha (0.89) and ICC (0.99 for the performance subtest and 0.98 for the satisfaction subtest). Correlation coefficients did not show a correlation between the COPM total score and the SCIM. The COPM scores improved significantly during in-patient rehabilitation, moreover the mean change between the start of treatment and the end of the therapy as evaluated with the Wilcoxon signed-rank test was -4.25 points for the performance score and -2.96 points for the satisfaction score. Conclusions: This study showed that the COPM is a reliable tool for assessing SCI clients' perceived performance of daily activities and their satisfaction with their performance.

Spanish Transcultural Adaptation of the Activity Card Sort.

The Activity Card Sort (ACS) measures the level of participation, as perceived by each person which, unlike other scales, makes it both personal and significant. However, there is a limitation to applying the ACS to Spanish older adults as it is restricted to culturally relevant activities solely in the United States. Therefore, the aim of this study was to select activity items that reflected Spanish older adults' lifestyles in order to develop the Activity Card Sort-Spain Version (ACS-SP). Frequently, activities performed in Spain (n = 103) were listed in an initial draft. The Likert scale was administrated to a large group of Spanish nationals over the age of 60 years (n = 98) to establish which type of activities will be eventually included in the Spanish version. The final version was drawn up comprising 79 activities distributed between four performance areas. In addition, other activities that were not previously included by other assessment tools were considered and have been listed in this review, such as taking a nap, going out for a drink or "tapas," or searching for a job. The gradual adaptation to ACS for Spaniards will make it possible to measure the level of an individual's participation within a community. However, further work on psychometric properties is needed.

PEXO - A Pediatric Whole Hand Exoskeleton for Grasping Assistance in Task-Oriented Training.

Children with hand motor impairment due to cerebral palsy, traumatic brain injury, or pediatric stroke are considerably affected in their independence, development, and quality of life. Treatment conventionally includes task-oriented training in occupational therapy. While dose and intensity of hand therapy can be promoted through technology, these approaches are mostly limited to large stationary robotic devices for non-task-oriented training, or passive wearable devices for children with mild impairments. Here we present PEXO, a fully wearable actuated pediatric hand exoskeleton to cover the special needs of children (6 to 12 years of age) with strong impairments in hand function. Through three degrees of freedom, PEXO provides assistance in various grasp types needed for the execution of functional tasks. It is lightweight, water proof, and inherently interacts safely with the user. It meets mechanical requirements such as force, fast closing movement, and battery lifetime derived from literature and discussions with clinicians. Appealing appearance, user-friendly design, and intuitive control with visual feedback of forearm muscle activity should keep the user motivated during training in the clinic or at home. A pilot test with a 6-years old child with stroke showed that PEXO can provide assistance in grasping various objects weighing up to 0.5 kg. These are promising first results on the way to make hand exoskeletons accessible for children with neuromotor disorders.

Robotic-assisted therapy with bilateral practice improves task and motor performance in the upper extremities of chronic stroke patients: A randomised controlled trial.

BACKGROUND/AIM: Task-specific repetitive training, a usual care in occupational therapy practice, and robotic-aided rehabilitation with bilateral practice are used to improve upper limb motor and task performance. The difference in effects of two strategies requires exploration. This study compared the impact of robotic-assisted therapy with bilateral practice (RTBP) and usual task-specific training facilitated by therapists on task and motor performance for stroke survivors. METHODS: Forty-three community-dwelling stroke survivors (20 males; 23 females; 53.3 ± 13.1 years; post-stroke duration 14.2 ± 10.9 months) were randomised into RTBP and usual care. All participants received a 10-minute per-protocol sensorimotor stimulation session prior to interventions as part of usual care. Primary outcome was different in the amount of use (AOU) and quality of movement (QOM) on the Motor Activity Log (MAL) scale at endpoint. Secondary outcomes were AOU and QOM scores at follow-up, and pre-post and follow-up score differences on the Fugl-Meyer Assessment (FMA) and surface electromyography (sEMG). Friedman and Mann-Whitney U tests were used to calculate difference. RESULTS: There were no baseline differences between groups. Both conditions demonstrated significant within-group improvements in AOU-MAL and FMA scores following treatment (P < 0.05) and improvements in FMA scores at follow-up (P < 0.05). The training-induced improvement in AOU (30.0%) following treatment was greater than the minimal detectable change (16.8%) in the RTBP group. RTBP demonstrated better outcomes in FMA wrist score (P = 0.003) and sEMG of wrist extensor (P = 0.043) following treatment and in AOU (P < 0.001), FMA total score (P = 0.006), FMA wrist score (P < 0.001) and sEMG of wrist extensor (P = 0.017) at follow-up compared to the control group. Control group boost more beneficial effects on FMA hand score (P = 0.049) following treatment. CONCLUSIONS: RTBP demonstrated superior upper limb motor and task performance outcomes compared to therapists-facilitated task training when both were preceded by a 10-minute sensorimotor stimulation session.
