RESUMO
AIM: To evaluate available evidence examining safety and efficacy of non-invasive brain stimulation (NIBS) on upper extremity outcomes in children with cerebral palsy (CP). METHOD: We electronically searched 12 sources up to May 2023 using JBI and Cochrane guidelines. Two reviewers selected articles with predetermined eligibility criteria, conducted data extraction, and assessed risk of bias using the Cochrane Risk of Bias criteria. RESULTS: Nineteen studies were included: eight using repetitive transcranial magnetic stimulation (rTMS) and 11 using transcranial direct current stimulation (tDCS). Moderate certainty evidence supports the safety of rTMS and tDCS for children with CP. Very low to moderate certainty evidence suggests that rTMS and tDCS result in little to no difference in upper extremity outcomes. INTERPRETATION: Evidence indicates that NIBS is a safe and feasible intervention to target upper extremity outcomes in children with CP, although it also indicates little to no significant impact on upper extremity outcomes. These findings are discussed in relation to the heterogeneous participants' characteristics and stimulation parameters. Larger studies of high methodological quality are required to inform future research and protocols for NIBS.

AIM: The purpose of this case series was to describe physical activity (PA) amount and intensity in the home and school environment. Accelerometers and heart rate (HR) monitors are reliable and valid measures of PA in children with cerebral palsy (CP) who can walk. There is limited research on PA measures in children with CP who cannot walk. METHODS: Three 9-year-old boys with CP, Gross Motor Function Classification System levels IV and V, participated in a 1-week measurement period wearing waist- and wrist-worn triaxial accelerometers to measure PA counts and a wrist-worn HR monitor to measure PA intensity. PA intensity was calculated using an estimated HR max. Accelerometer counts were reported. Parents and school staff completed activity and eating journals. RESULTS: Six days of PA and HR data were analyzed. Two participants spent more time in moderate/vigorous PA intensity during school compared to at home. Activities with greatest PA intensity included oral eating, communication, and social engagement. Higher activity counts were recorded from the wrist compared with the waist accelerometers. PA and eating journal adherence were high in both settings. CONCLUSION: The findings provide preliminary data to evaluate PA amount and intensity in children with CP who have little walking ability. It is important to consider PA levels in daily activity for youth with CP when designing plans of care.

Smartphone sensors are used increasingly in the assessment of ataxias. To date, there is no specific consensus guidance regarding a priority set of smartphone sensor measurements, or standard assessment criteria that are appropriate for clinical trials. As part of the Ataxia Global Initiative Digital-Motor Biomarkers Working Group (AGI WG4), aimed at evaluating key ataxia clinical domains (gait/posture, upper limb, speech and oculomotor assessments), we provide consensus guidance for use of internal smartphone sensors to assess key domains. Guidance was developed by means of a literature review and a two stage Delphi study conducted by an Expert panel, which surveyed members of AGI WG4, representing clinical, research, industry and patient-led experts, and consensus meetings by the Expert panel to agree on standard criteria and map current literature to these criteria. Seven publications were identified that investigated ataxias using internal smartphone sensors. The Delphi 1 survey ascertained current practice, and systems in use or under development. Wide variations in smartphones sensor use for assessing ataxia were identified. The Delphi 2 survey identified seven measures that were strongly endorsed as priorities in assessing 3/4 domains, namely gait/posture, upper limb, and speech performance. The Expert panel recommended 15 standard criteria to be fulfilled in studies. Evaluation of current literature revealed that none of the studies met all criteria, with most being early-phase validation studies. Our guidance highlights the importance of consensus, identifies priority measures and standard criteria, and will encourage further research into the use of internal smartphone sensors to measure ataxia digital-motor biomarkers.
RESUMO
OBJECTIVE: To investigate physical activity levels of individuals with ataxia and correlate fitness to ataxia severity. DESIGN: An observational study SETTING: An outpatient ataxia clinic in a large, tertiary, urban hospital in the US. PARTICIPANTS: Individuals with cerebellar ataxia (N=42). INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Participants were classified as sedentary or physically active using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Maximal oxygen consumption (VÌo2max) as an indicator of fitness level was measured, and ataxia severity was determined by the Scale for the Assessment and Rating of Ataxia (SARA). Mixed effect models were used to correlate ataxia severity to fitness levels. RESULTS: Most participants (28 out of 42) lived sedentary lifestyles, and these individuals had poor fitness levels (only 67.3% of their predicted measure). The main barriers to physical activity included lack of energy, lack of time, and fear of falling. There were no differences in age, sex, disease type, disease duration, ataxia severity, fatigue level, and medication use between sedentary and active groups. Measures of VÌo2max, maximal work, maximal heart rate, and anerobic threshold demonstrated statistically significant differences between groups whereas maximal respiratory rate and expired ventilation/carbon dioxide production were similar between groups. When adjusting for age, sex, functional mobility status, and disease duration, ataxia severity was inversely correlated with fitness level in the sedentary group. There was no relationship between ataxia severity and fitness level in the 14 individuals who were physically active. CONCLUSIONS: Lower fitness levels were associated with more ataxia symptoms in the sedentary group. This relationship was not seen in individuals who were more active. Given the poor health outcomes associated with low fitness, physical activity should be encouraged in this population.

BACKGROUND AND PURPOSE: Physical activity (PA) has many known benefits for people with Parkinson disease (PD); however, many people do not meet recommended levels of frequency or intensity. We designed Engage-PD, a PA coaching program delivered via telehealth and grounded in self-determination theory to promote PA uptake and facilitate exercise self-efficacy in people with Parkinson disease. This study aimed to determine the feasibility and preliminary efficacy of Engage-PD, and to explore whether baseline characteristics were associated with outcomes. METHODS: A single cohort of people with PD (n = 62, Hoehn and Yahr I-III) participated in the 3-month Engage-PD program, which consisted of up to 5 telehealth coaching sessions delivered by physical therapists. Feasibility was evaluated based on recruitment and retention rates, along with participants' feedback. Planned and unplanned PA, exercise self-efficacy (ESE), and individualized goals were assessed pre- and post-intervention. Relationships between baseline characteristics and changes in planned PA and ESE were also evaluated. RESULTS: Recruitment (62%) and retention (85%) rates were high, and the intervention was well accepted and perceived by the participants. From pre- to postintervention, participants increased planned PA (d = 0.33), ESE (d = 1.20), and individualized goal performance (d = 1.63) and satisfaction (d = 1.70). Participants with lower baseline planned PA experienced greater improvements in planned PA, and those with lower baseline ESE experienced greater improvements in ESE. DISCUSSION AND CONCLUSIONS: A telehealth PA coaching program for people with PD was feasible and potentially efficacious. Physical therapist-led coaching may be an important component of a consultative model of care starting early in the disease process.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A393).

BACKGROUND: Individuals with hemiparesis post-stroke often have difficulty with tasks requiring upper extremity (UE) intra- and interlimb use, yet methods to quantify both are limited. OBJECTIVE: To develop a quantitative yet sensitive method to identify distinct features of UE intra- and interlimb use during task performance. METHODS: Twenty adults post-stroke and 20 controls wore five inertial sensors (wrists, upper arms, sternum) during 12 seated UE tasks. Three sensor modalities (acceleration, angular rate of change, orientation) were examined for three metrics (peak to peak amplitude, time, and frequency). To allow for comparison between sensor data, the resultant values were combined into one motion parameter, per sensor pair, using a novel algorithm. This motion parameter was compared in a group-by-task analysis of variance as a similarity score (0-1) between key sensor pairs: sternum to wrist, wrist to wrist, and wrist to upper arm. A use ratio (paretic/non-paretic arm) was calculated in persons post-stroke from wrist sensor data for each modality and compared to scores from the Adult Assisting Hand Assessment (Ad-AHA Stroke) and UE Fugl-Meyer (UEFM). RESULTS: A significant group × task interaction in the similarity score was found for all key sensor pairs. Post-hoc tests between task type revealed significant differences in similarity for sensor pairs in 8/9 comparisons for controls and 3/9 comparisons for persons post stroke. The use ratio was significantly predictive of the Ad-AHA Stroke and UEFM scores for each modality. CONCLUSIONS: Our algorithm and sensor data analyses distinguished task type within and between groups and were predictive of clinical scores. Future work will assess reliability and validity of this novel metric to allow development of an easy-to-use app for clinicians.

BACKGROUND AND PURPOSE: Gait asymmetries are common after stroke, and often persist despite conventional rehabilitation. Robots provide training at a greater practice frequency than conventional approaches. However, prior studies of have found the transfer of learned skills outside of the device to be inadequate. The tethered pelvic assist device (TPAD) promotes weight shifting, yet allows users to independently navigate spatiotemporal aspects of gait. The purpose of this study was to evaluate feasibility and preliminary efficacy of a 5-day intervention combining TPAD training with visual feedback and task-specific overground training to promote improved force and stance symmetry in individuals after stroke. METHODS: After baseline assessments, 11 participants chronically after stroke received 1 hour of practice for 5 consecutive days. Training sessions included visual feedback during TPAD treadmill training followed by overground gait training. Safety, perceived exertion, and adherence were recorded as measures of feasibility. Load and stance symmetry were reassessed after the intervention (posttraining) and again 1 week later. RESULTS: No adverse events were reported. Mean (SD) perceived exertion (3.61 (0.23)) was low and did not significantly change throughout the intervention. Overall adherence was 96.4%. Load asymmetry was not significantly reduced on the treadmill from baseline to posttraining (P = 0.075). Overground stance symmetry significantly improved on posttraining (F = 8.498, P = 0.002), but was not sustained at follow-up. (See the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A311, which summarizes the study background, methods, and results.) DISCUSSION AND CONCLUSIONS:: Results demonstrate this combined interventional approach was feasible and improved stance symmetry overground, yet further work should consider increasing training intensity and/or duration to induce gains lasting through follow-up.

INTRODUCTION: Goal setting is an important component of school-based physical therapy; however, evidence suggests that therapists may not consistently write goals that are relevant, context specific, and measurable. The aims of this knowledge translation study were to evaluate implementation of a goal-setting method for school-based therapists. METHOD: This study was created to align with the Knowledge to Action framework and included 1-day training and follow-up mentorship. Goals were assessed pre- and posttraining, and questionnaires assessed barriers and facilitators. RESULTS: Twenty-two physical therapists participated. Nineteen participants (90%) strongly agreed/agreed that the training helped change their perspectives about goal setting in the school environment. There was a statistically significant difference in goal quality pre- and posttraining. Therapists identified barriers and facilitators to implementation of effective goal setting in practice. DISCUSSION: Results indicate that this method may be effective at improving goal writing that is relevant, context specific, and measurable in school settings.

The compromise of quality of life in Huntington's disease is a major issue, both for individuals with the disease as well as for their caregivers. The International Parkinson and Movement Disorder Society commissioned a review of the use and clinimetric validation status of measures used in Huntington's disease to assess aspects related with quality of life and to make recommendations on their use following standardized criteria. We included both patient-centered measures (patient health-related quality-of-life measures) and caregiver-centered measures (caregiver quality-of-life measures). After conducting a systematic literature search, we included 12 measures of patient health-related quality of life and 2 measures of caregiver quality of life. Regarding patient-centered measures, the Medical Outcomes Study 36-Item Short-Form Health Survey is "recommended" as a generic assessment of health-related quality of life in patients with Huntington's disease. The 12-Item Short Form Health Survey, the Sickness Impact Profile, the 12-item World Health Organization Disability Assessment Schedule, and the Huntington's Disease Health-Related Quality of Life questionnaire are "suggested." No caregiver-centered quality-of-life measure obtained a "recommended" status. The Alzheimer's Carer's Quality of Life Inventory and the Huntington's Disease Quality of Life Battery for Carers are "suggested." Recognizing that the assessment of patient health-related quality of life can be challenging in Huntington's disease, as patients may lack insight and there is insufficient clinimetric testing of these scales, the committee concluded that further validation of currently available health-related quality-of-life measures should be undertaken, namely, those Huntington's disease-specific health-related quality-of-life measures that have recently been reported and used. © 2018 International Parkinson and Movement Disorder Society.

BACKGROUND AND PURPOSE: The APTA recently established a vision for physical therapists to transform society by optimizing movement to promote health and wellness, mitigate impairments, and prevent disability. An important element of this vision entails the integration of the movement system into the profession, and necessitates the development of movement system diagnoses by physical therapists. At this point in time, the profession as a whole has not agreed upon diagnostic classifications or guidelines to assist in developing movement system diagnoses that will consistently capture an individual's movement problems. We propose that, going forward, diagnostic classifications of movement system problems need to be developed, tested, and validated. The Academy of Neurologic Physical Therapy's Movement System Task Force was convened to address these issues with respect to management of movement system problems in patients with neurologic conditions. The purpose of this article is to report on the work and recommendations of the Task Force. SUMMARY OF KEY FINDINGS: The Task Force identified 4 essential elements necessary to develop and implement movement system diagnoses for patients with primarily neurologic involvement from existing movement system classifications. The Task Force considered the potential impact of using movement system diagnoses on clinical practice, education and, research. Recommendations were developed and provided recommendations for potential next steps to broaden this discussion and foster the development of movement system diagnostic classifications. RECOMMENDATIONS FOR CLINICAL PRACTICE: The Task Force proposes that diagnostic classifications of movement system problems need to be developed, tested, and validated with the long-range goal to reach consensus on and adoption of a movement system diagnostic framework for clients with neurologic injury or disease states.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A198).

BACKGROUND AND PURPOSE: Over the last decade there has been a substantial increase in efforts to better understand how targeted physical activity and exercise interventions can be used to minimize secondary consequences arising from neurological damage in both adult and pediatric populations. This article offers an overview of contemporary research that addresses mediators of functional and neuroplastic adaptations associated with physical activity and exercise. We emphasize the important role that physical therapists can play to increase participation and improve well-being in adults and children with neurological disorders. We further highlight potential strategies to foster translation of evidence-based findings for use by clinicians and consumers. SUMMARY OF KEY POINTS: Engagement in physical activity can serve as a powerful promoter of health and well-being in adults and youth with neurologic disease, and has the potential to alter the course of disease processes. Physical therapists can play a key role in promoting fitness and wellness by encouraging active living, providing early diagnosis of disease and prescribing targeted activity interventions to improve fitness and participation, and helping individuals overcome personal and environmental barriers to an active lifestyle. RECOMMENDATIONS FOR CLINICAL PRACTICE: Physical therapists must adopt a model of rehabilitation that emphasizes secondary prevention in adults and youth with neurologic diseases. Physical therapists have a unique role in developing forward-thinking approaches in using innovative health and wellness strategies to promote positive changes in activity and exercise behaviors.

BACKGROUND AND PURPOSE: Individuals with Huntington disease (HD), a rare neurological disease, experience impairments in mobility and cognition throughout their disease course. The Medical Research Council framework provides a schema that can be applied to the development and evaluation of complex interventions, such as those provided by physical therapists. Treatment-based classifications, based on expert consensus and available literature, are helpful in guiding physical therapy management across the stages of HD. Such classifications also contribute to the development and further evaluation of well-defined complex interventions in this highly variable and complex neurodegenerative disease. The purpose of this case series was to illustrate the use of these classifications in the management of 2 individuals with late-stage HD. CASE DESCRIPTION: Two females, 40 and 55 years of age, with late-stage HD participated in this case series. Both experienced progressive declines in ambulatory function and balance as well as falls or fear of falling. Both individuals received daily care in the home for activities of daily living. INTERVENTION: Physical therapy Treatment-Based Classifications for HD guided the interventions and outcomes. Eight weeks of in-home balance training, strength training, task-specific practice of functional activities including transfers and walking tasks, and family/carer education were provided. OUTCOMES: Both individuals demonstrated improvements that met or exceeded the established minimal detectible change values for gait speed and Timed Up and Go performance. Both also demonstrated improvements on Berg Balance Scale and Physical Performance Test performance, with 1 of the 2 individuals exceeding the established minimal detectible changes for both tests. Reductions in fall risk were evident in both cases. DISCUSSION: These cases provide proof-of-principle to support use of treatment-based classifications for physical therapy management in individuals with HD. Traditional classification of early-, mid-, and late-stage disease progression may not reflect patients' true capabilities; those with late-stage HD may be as responsive to interventions as those at an earlier disease stage.Video Abstract available for additional insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A172).

BACKGROUND AND PURPOSE: We studied the development and delivery of a 14-week complex physical activity intervention for people with Huntington disease, where detailed information about the intervention was fully embedded in the trial design process. METHODS: Intervention Development: The intervention was developed through a series of focus groups. The findings from the focus groups informed the development of a logic model for the physical activity intervention that was broadly consistent with the framework of self-determination theory. Intervention Delivery: Key components underpinning the delivery of the intervention were implemented including a defined coach training program and intervention fidelity assessment methods. Training of coaches (physical therapists, occupational therapists, research nurses, and exercise trainers) was delivered via group and 1:1 training sessions using a detailed coach's manual, and with ongoing support via video calls, and e-mail communication as needed. Detailed documentation was provided to determine costs of intervention development and coach training. RESULTS: Intervention delivery coaches at 8 sites across the United Kingdom participated in the face-to-face training. Self-report checklists completed by each of the coaches indicated that all components of the intervention were delivered in accordance with the protocol. Mean (standard deviation) intervention fidelity scores (n = 15), as measured using a purpose-developed rating scale, was 11 (2.4) (out of 16 possible points). Coaches' perceptions of intervention fidelity were similarly high. The total cost of developing the intervention and providing training was £30,773 ($47,042 USD). DISCUSSION AND CONCLUSIONS: An important consideration in promoting translation of clinical research into practice is the ability to convey the detailed components of how the intervention was delivered to facilitate replication if the results are favorable. This report presents an illustrative example of a physical activity intervention, including the development and the training required to deliver it. This approach has the potential to facilitate reproducibility, evidence synthesis, and implementation in clinical practice.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A122).

Background: Huntington's disease (HD) is an autosomal dominant, neurodegenerative disease that involves dysfunction in the autonomic nervous system (ANS). Heart rate variability (HRV) is a valid and noninvasive measure for ANS dysfunction, yet no study has characterized HRV response to exercise in people with HD. Objective: Characterize HRV response to exercise in individuals with HD and explore its implications for exercise prescription and cardiac dysautonomia mechanisms. Methods: 19 participants with HD were recruited as part of a cohort of individuals enrolled in the Physical Activity and Exercise Outcomes in Huntington's Disease (PACE-HD) study at Teachers College, Columbia University (TC). 13 non-HD age- and gender-matched control participants were also recruited from TC. HRV was recorded with a Polar H10 heart rate (HR) monitor before, during, and after a ramp cycle-ergometer exercise test. Results: Participants with HD showed reduced HR peak (pâ<â0.01) and HR reserve (pâ<â0.001) compared with controls. Participants with HD demonstrated reduced root mean square of successive differences between normal-to-normal intervals (RMSSD) and successive differences of normal-to-normal intervals (SDSD) at rest (pâ<â0.001). Participants with HD also showed differences for low frequency (LF) power (pâ<â0.01), high frequency (HF) normalized units (nu) (pâ<â0.05), LF (nu) (pâ<â0.001), and HF/LF ratio (pâ<â0.05) compared with controls. Conclusions: We found reduced aerobic exercise capacity and sympathovagal dysautonomia both at rest and during post-exercise recovery in people with HD, suggesting modified exercise prescription may be required for people with HD. Further investigations focusing on cardiac dysautonomia and underlying mechanisms of sympathovagal dysautonomia in people with HD are warranted.

PURPOSE: Sensorimotor cough skill training (CST) has been shown to improve cough strength, as well as facilitate changes during training (i.e., motor performance) and generalization to untrained tasks (i.e., motor learning). However, there is a gap in our understanding of the effects of voluntary CST (without sensory stimuli) on motor performance and learning. Furthermore, the contribution of physiologic factors, such as lung volume, a driver of cough strength in healthy adults, and treatment-specific factors, such as biofeedback, remains unexamined. METHOD: Twenty individuals with Parkinson's disease (PD) completed pre- and post-CST single voluntary, sequential voluntary, and reflex cough testing. Participants were randomized to biofeedback or no biofeedback groups. They completed one CST session involving 25 trials of voluntary coughs, with the treatment target set 25% above baseline peak flow. Participants were instructed to "cough hard" to exceed the target. In the biofeedback group, participants received direct visualization of the target line in real time. RESULTS: Cough peak flow showed positive improvements in motor performance (ß = .02; 95% credible interval [CI]: 0.01, 0.03) and learning (ß = .26; 95% CI: 0.03, 0.47). Changes in lung volume from pre- to post-CST did not predict treatment response. No differences in treatment response were detected between the biofeedback groups. CONCLUSIONS: A single session of voluntary CST improved voluntary cough motor performance and learning. Although lung volume increased during CST, changes to lung volume did not predict treatment response. These findings demonstrate the potential of voluntary CST to improve motor performance and motor learning among individuals with PD and cough dysfunction.

BACKGROUND: The ability to objectively measure spatiotemporal metrics within individuals post-stroke is integral to plan appropriate intervention, track recovery, and ultimately improve efficacy of rehabilitation programs. Inertial measurement units (IMUs) provide a means to systematically collect gait-specific metrics that could not otherwise be obtained from clinical outcomes. However, the use of IMUs to measure spatiotemporal parameters in stroke survivors has yet to be validated. The purpose of this study is to determine the validity and reliability of IMU-recorded spatiotemporal gait metrics as compared to a motion capture camera system (MCCS) in individuals post-stroke. METHODS: Participants (n = 23, M/F = 12/11, mean (SD) age = 50.2(11.1) spatiotemporal data were collected simultaneously from a MCCS and APDM Opal IMUs during a five-minute treadmill walking task at a self-selected speed. Criterion validity and test-retest reliability were assessed using Lin's concordance correlation coefficients (CCCs) and intraclass correlation coefficients (ICCs), respectively. Spatiotemporal values from MCCS and IMU were used to calculate gait asymmetry, and a t-test was used to assess the difference between asymmetry values. RESULTS: There were fair-to-excellent agreement between IMU and MCCS of temporal parameters (CCC 0.56-0.98), excellent agreement of spatial parameters (CCC >0.90), and excellent test-retest reliability for all parameters (ICC >0.90). CONCLUSIONS: Compared to motion capture, the APDM Opal IMUs produced accurate and reliable measures of spatiotemporal parameters. Findings support the use of IMUs to assess spatiotemporal parameters in individual's post-stroke.

Functional neurological disorder (FND) is a heterogeneous condition of neurological symptoms that cannot be linked to a specific neurological cause. Yoga combines movement, breathing, and meditation and has established mind-body effects for people who are managing both psychological and neurological conditions. This case series describes key components of a yoga program for people with FND, evaluating feasibility, acceptability, and efficacy via self-report surveys, clinical assessments, and postintervention interview. Four individuals with FND participated in 45-minute, one-to-one virtual yoga sessions, two times a week for 8 weeks. We measured outcomes in four domains (healthcare utilization, FND symptoms, quality of life and self-efficacy, and function and mobility) at baseline, week 4, and week 8. Assessments included the Psychogenic Movement Disorders Rating Scale, timed up-and-go test, Patient Health Questionnaire-15, Brief Illness Perceptions Questionnaire, 36-Item Short Form Health Survey, and University of Washington Self-Efficacy Scale. Four participants completed at least 8 sessions, and two completed the full intervention (16 sessions). There were no adverse events. Two participants reported positive changes after yoga and improved on all clinical assessments (timed up-and-go test and Psychogenic Movement Disorders Rating Scale). Postintervention interview analysis revealed three themes: negative diagnosis experience, perceived health effects of yoga, and session format preferences. This was an exploratory case series describing a yoga intervention that was associated with some benefits for people with FND (decreased FND symptom severity and increased function, perceived health, quality of life, and self-efficacy). A larger case series is warranted to understand how to best select individuals who would benefit from the program.

INTRODUCTION: Parkinson disease (PD) is the second most common neurodegenerative disease. Members of the Black Diaspora (MBD) and Hispanic/Latinx people are less likely to receive a timely diagnosis following the onset of symptoms and more likely to experience greater disease severity due to late diagnosis. Historically marginalized populations (i.e., MBD, Hispanic, and Latinx communities) are not accurately represented in research; this, along with many other barriers, compounds underreporting and lack of recognition of PD. It is important to understand barriers to early diagnosis and healthcare access for these historically marginalized populations from the community's perspective. METHODS: Our team conducted two focus groups to identify barriers and facilitators to PD healthcare-seeking behavior. We sought to identify which barriers are modifiable to ultimately improve engagement in neurological care for MBD and Hispanic individuals affected by PD. RESULTS: We enrolled 15 participants (13 female; African/African American/Black n = 10, Hispanic/Puerto Rican n = 3, other n = 2) for two focus groups. Discussions revealed sources of barriers to healthcare-seeking behavior in three main domains: legacy of racism in the United States, ancestral cultural environment, and healthcare system access. These sources influenced individuals' PD knowledge and familiarity. Additionally, participants expressed a desire to know more about PD and called for increased community-based programming for education and awareness. DISCUSSION: This paper uses a community-based participatory research approach to describe the experiences of MBD, Hispanic, and Latinx people in Manhattan and the surrounding areas in relation to possible sources of healthcare disparities and delayed PD diagnosis. These sources have broad implications and should be addressed through collaborative community programming.
RESUMO
BACKGROUND AND PURPOSE: The beneficial role of exercise as a treatment approach in Huntington's disease (HD) has support from both preclinical work and small-scale studies; however, there have been no controlled studies of gym-based exercise in people with HD. This phase 2 randomized trial (ISRCTN 59910670) assessed feasibility, safety, acceptability, and benefit of a structured exercise program. METHODS: Thirty-one participants (16 men; mean [SD] age = 50.4 [11.4] years) were randomly allocated to intervention (n = 16) or control group (usual care; n = 15). The intervention entailed a weekly supervised gym session of stationary cycling and resistance exercises, and a twice weekly independent home-based walking program. Retention and adherence rates and adverse events were recorded. Acceptability was determined from subjective reports of tolerability and physiological measures recorded during the gym sessions. Assessment of benefit included measures of physical abilities, disease severity, and quality of life (36-Item Short Form Health Survey). Analysis of covariance was used to test outcomes of interest. RESULTS: The retention rate was 81% (9 of the 11 individuals who started the intervention completed it) and of the 9 who completed the program, 7 attended more than 75% (9/12) of the gym sessions. There were no related adverse events and the intervention was well tolerated by most participants. The between-group effect estimate for the Mental Component Summary score of the 36-Item Short Form Health Survey (n = 9; intervention, n = 13; control) was 7 (95% CI: 0.4-13.7) Moderate effect sizes for cognitive outcomes and measures of walking were also observed. DISCUSSION AND CONCLUSIONS: Observed effect sizes for clinical outcomes suggest the structured exercise program has benefit for persons with HD; larger scale trials are warranted.Video Abstract available (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A60) for more insights from the authors.
