RESUMO
STUDY DESIGN: Mixed-method approach. OBJECTIVES: To develop and assess the content validity of a semi-structured interview that captures the lived experience of using a manual wheelchair among individuals with SCI in the real world, the Wheelchair Mobility Activity Log (WC-MAL). SETTING: SCIR-Group (UDESC)/Brazil. METHODS: Developing the WC-MAL comprised five steps: (1) defining the construct-based on the International Classification of Functioning, Disability and Health (ICF); (2) identifying relevant activities from other assessment instruments and interviews with the end-users (14 Individuals with SCI and 13 rehabilitation professionals); (3) Selecting the items - activities were linked to ICF codes and grouped into sets; (4) developing the scoring scales based on interviews with the end-users; and, (5) evaluating content validity in accordance with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). The content validity ratio (CVR) for each item and scale and the overall instrument content validity index (CVI) were calculated. RESULTS: From an initial draft of 295 activities identified, a set of 222 activities was linked to the ICF domain of "Mobility (d4)" and further refined to generate the 23 items in the WC-MAL. Three scales were developed to assess Frequency (how often), Performance (how well), and Assistance (assistance needed) levels. The items and scales showed a CVR superior to the critical value established (≥0.64). The general CVI value was 0.96. CONCLUSION: The WC-MAL is a promising clinical instrument with adequate content validity to assess the spontaneous use of the manual wheelchair in the real world among individuals with SCI.

INTRODUCTION: Repetitive peripheral sensory stimulation (RPSS) followed by 4-hour task-specific training (TST) improves upper limb motor function in subjects with stroke who experience moderate to severe motor upper limb impairments. Here, we compared effects of RPSS vs sham followed by a shorter duration of training in subjects with moderate to severe motor impairments in the chronic phase after stroke. METHODS: This single-center, randomized, placebo-controlled, parallel-group clinical trial compared effects of 18 sessions of either 1.5 h of active RPSS or sham followed by a supervised session that included 45 min of TST of the paretic upper limb. In both groups, subjects were instructed to perform functional tasks at home, without supervision. The primary outcome measure was the Wolf Motor Function Test (WMFT) after 6 weeks of treatment. Grasp and pinch strength were secondary outcomes. RESULTS: In intention-to-treat analysis, WMFT improved significantly in both active and sham groups at 3 and 6 weeks of treatment. Grasp strength improved significantly in the active, but not in the sham group, at 3 and 6 weeks. Pinch strength improved significantly in both groups at 3 weeks, and only in the active group at 6 weeks. CONCLUSIONS: The between-group difference in changes in WMFT was not statistically significant. Despite the short duration of supervised treatment, WMFT improved significantly in subjects treated with RPSS or sham. These findings are relevant to settings that impose constraints in duration of direct contact between therapists and patients. In addition, RPSS led to significant gains in hand strength.Trial Registry Name: Peripheral Nerve Stimulation and Motor Training in Stroke Clinical Trials.gov identifier: NCT0265878 https://clinicaltrials.gov/ct2/show/NCT02658578.

Background: Upper extremity impairment is present in most of people with stroke. The use of the affected upper extremity can be impacted not only by physical impairment but also by abehavioral phenomenon called learned nonuse. Objective: The aim of this study was to evaluate which clinical factors in the acute phase are associated with the development of learned nonuse in the upper extremity after stroke. Methods: This cohort study included 38 patients with ischemic stroke. Hospital discharge data were collected for clinical aspects, scales of severity, incapacity and autonomy, as well as for neuromuscular and sensory evaluations. At 90 days after hospital discharge, the score on the Motor Activity Log scale for detecting learned nonuse was obtained, and life quality was evaluated by the EuroQol. The individuals with and without learned nonuse were compared by attest for univariate analysis, and ageneralized linear model was employed to find possible predictors, which were considered significant p <0.05. Results: In the statistical model, age (p= .006), severity at discharge (p= .036), handgrip strength (p= .000), altered sensitivity (p= .011), incapacity at discharge (p= .009) and autonomy at discharge (p= .011) were found to be associated with learned nonuse. In relation to quality of life, mobility, personal care, usual activities, anxiety, depression and perception had lower mean values in the learned nonuse group. Conclusion: Age, severity of stroke, incapacity and neuromuscular and sensory compromises are associated with upper extremity learned nonuse in stroke patients.
