RESUMEN
BACKGROUND: Recent technological advancements present promising opportunities to enhance the frequency and objectivity of functional assessments, aligning with recent stroke rehabilitation guidelines. Within this framework, we designed and adapted different manual dexterity tests in extended reality (XR), using immersive virtual reality (VR) with controllers (BBT-VR-C), immersive VR with hand-tracking (BBT-VR-HT), and mixed-reality (MD-MR). OBJECTIVE: This study primarily aimed to assess and compare the validity of the BBT-VR-C, BBT-VR-HT and MD-MR to assess post-stroke manual dexterity. Secondary objectives were to evaluate reliability, usability and to define arm kinematics measures. METHODS: A sample of 21 healthy control participants (HCP) and 21 stroke individuals with hemiparesis (IHP) completed three trials of the traditional BBT, the BBT-VR-C, BBT-VR-HT and MD-MR. Content validity of the different tests were evaluated by asking five healthcare professionals to rate the difficulty of performing each test in comparison to the traditional BBT. Convergent validity was evaluated through correlations between the scores of the traditional BBT and the XR tests. Test-retest reliability was assessed through correlations between the second and third trial and usability was assessed using the System Usability Scale (SUS). Lastly, upper limb movement smoothness (SPARC) was compared between IHP and HCP for both BBT-VR test versions. RESULTS: For content validity, healthcare professionals rated the BBT-VR-HT (0[0-1]) and BBT-MR (0[0-1]) as equally difficult to the traditional BBT, whereas they rated BBT-VR-C as more difficult than the traditional BBT (1[0-2]). For IHP convergent validity, the Pearson tests demonstrated larger correlations between the scores of BBT and BBT-VR-HT (r = 0.94;p < 0.001), and BBT and MD-MR (r = 0.95;p < 0.001) than BBT and BBT-VR-C (r = 0.65;p = 0.001). BBT-VR-HT and MD-MR usability were both rated as excellent, with median SUS scores of 83[57.5-91.3] and 83[53.8-92.5] respectively. Excellent reliability was found for the BBT-VR-C (ICC = 0.96;p < 0.001), BBT-VR-HT (ICC = 0.96;p < 0.001) and BBT-MR (ICC = 0.99;p < 0.001). The usability of the BBT-VR-C was rated as good with a median SUS of 70[43.8-83.8]. Upper limb movements of HCP were significantly smoother than for IHP when completing either the BBT-VR-C (t = 2.05;p = 0.043) and the BBT-VR-HT (t = 5.21;p < 0.001). CONCLUSION: The different XR manual tests are valid, short-term reliable and usable tools to assess post-stroke manual dexterity.

BACKGROUND: Only about 9% of individuals with intellectual disabilities reach the government's physical activity (PA) recommendations. Combining gamification and technology seems particularly promising in overcoming personal and environmental barriers to PA participation. METHOD: Eighteen adults with varying levels of intellectual disabilities completed a pilot study to assess the initial effects of a cycling gamification intervention on levels of PA, fitness, psychosocial outcomes, and challenging behaviours. The study comprised three designs: pre-post single group, AB single-case, and qualitative. Social validity, implementation barriers and facilitators were also explored. RESULTS: Nearly all 18 participants cycled daily. Time and distance cycled daily increase during the intervention while a decrease in stereotyped behaviours was observed. Participants and staff found the intervention enjoyable and socially valid. CONCLUSIONS: Results of the multiple-design study suggest that gamification interventions may be a suitable, enjoyable, and promising way to contribute to PA participation of adults with intellectual disabilities.

Background: The use of standardised assessment tools is a fundamental aspect of good clinical practice. However, to our knowledge, no study has documented the use of standardised assessment tools in physiotherapy in French-speaking sub-Saharan Africa. Objectives: Documenting the use of standardised outcome measures in physiotherapy in French-speaking sub-Saharan Africa. Method: Our cross-sectional survey used an online self-questionnaire on facilitators and barriers to the use of standardised outcome measures, distributed to physiotherapists in French-speaking sub-Saharan Africa. Results: A total of 241 physiotherapists working in French-speaking sub-Saharan Africa responded to the survey. The most represented countries were Benin (36.9%), Cameroon (14.1%), and Burkina Faso (10.8%). Although 99% of participants reported using standardised outcome measures, only 27% of the respondents used them systematically (all the time). The most reported facilitators included the recognition that standardised outcome measures help to determine whether treatment is effective, help to guide care, and improve communication with patients. The most significant barriers were the lack of time, unavailability of the standardised outcome measures, and non-sensitivity of measures to patients' cultural and ethnic concerns. There was a higher proportion of use in the middle age group (30-40) (p = 0.02) and a lower proportion of use in physiotherapists simultaneously working in public and private sectors (p = 0.05). Conclusion: Standardised outcome measures are still not widely used by physiotherapists in French-speaking sub-Saharan Africa. Clinical implications: The perceived barriers and facilitators could help to develop strategies to improve the systematic use of outcome measures in French-speaking sub-Saharan Africa.
RESUMEN
MATERIALS AND METHODS: We conducted a longitudinal study involving 81 stroke patients (mean (SD) age: 54.6 (10.8) years; 58% male, mean (SD) time after stroke onset: 4.3 (2.5) weeks). Participants were assessed at baseline (T1), two-month later (T2), and on average of 1.5 (0.5) years after stroke (T3), with the ABILOCO-Benin questionnaire, functional ambulation classification (FAC), six-minute walking test, ACTIVLIM-Stroke questionnaire, modified Rankin Scale, and Stroke Impairment Assessment Scale. Global-, sub-group- (stable and improved based on FAC scores), and individual-based analysis of changes were performed. RESULTS: Participants showed significantly larger improvement for all outcomes during the acute phase (T1-T2). Changes in the ABILOCO-Benin measures were significantly correlated with changes in other outcome measures. ABILOCO-Benin questionnaire detected a significant improvement in both the stable and improved groups at both T2 and T3 in the sub-group approach. Individual-based analysis with ABILOCO-Benin measures showed a significantly higher proportion of stable patients (n = 55) and lower proportion of improved ones (n = 23) between T2 and T3 (LR(df) = 15.52(4), p = 0.004). CONCLUSIONS: ABILOCO-Benin is responsive to changes in adult stroke patients within both acute and chronic phases. Implications for rehabilitationABILOCO-Benin questionnaire is highly responsive to changes in locomotion abilities of stroke patients within both acute (<6 months) and chronic (≥6 months) phases.It can be used in clinical and research practice to track changes in stroke patients after interventions in African settings and beyond.
