Psychosocial interventions for building resilience of informal carers of people living with stroke: a systematic review.

PURPOSE: To identify and synthesise the evidence of interventions purported to build resilience among informal carers of stroke survivors. METHODS: A systematic review of randomised controlled trials of psychosocial interventions to build resilience for carers of people post-stroke was planned. A systematic search was conducted in seven online databases from inception to March 2021. Outcomes measured were resilience and its proxy constructs including copying, adaptation, adjustment, problem-solving, self-efficacy, locus of control, competence and strength. RESULTS: Twelve studies were included in the review and were grouped into four intervention categories (i) Education and social support, (ii) problem-solving skills, (iii) problem-solving skills, and psychoeducation and (iv) information provision, problem-solving skills and psychoeducation. Level of evidence A exists for interventions that combine information provision, problem-solving skills and psychoeducation over the interventions that only use problem-solving skills intervention or problem-solving skills with psychoeducation strategies. All interventions apart from one reported significant within and/or between group changes in outcomes. CONCLUSION: Interventions comprising of information provision, problem-solving skills and psychoeducation appear to be beneficial to improve resilience of carers. However, because of the heterogeneity of the interventions and outcome measures reported across the twelve studies no particular intervention could be definitively supported. CLINICAL TRIAL REGISTRATION: Systematic review registration: CRD 42020172824 https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020172824 IMPLICATIONS FOR REHABILITATIONProviding care for stroke survivors is particularly demanding due to the lack of preparation for managing the unexpected and complex nature of stroke, resulting in negative physical, social, behavioral, emotional, and financial outcomes.The long-term nature of stroke and its many residual problems can negatively affect the physical and psychological well-being of the individual and their carers, which may subsequently affect the recovery of the stroke survivor.Evidence suggests that resilience is the protective shield for carers' stress and burnout.Integrating interventions focusing on carers' resilience as part of the stroke rehabilitation process is imperative to ensure the well-being of carers and the sustainability of the care provided to the stroke survivor.

Gait quality and velocity influences activity tracker accuracy in individuals post-stroke.

Objective: Fitbit Zip™ (FBZ) is a low-cost user-friendly device that could help motivate individuals post-stroke to increase their physical activity. However, inaccuracy in step counts from altered gait variables could cause dissatisfaction and reduce compliance. The aim of this study was to determine the influence of gait variables on the concurrent validity of the FBZ. Method: In a cross-sectional study, 19 community-dwelling stroke survivors (mean 66 (SD 8) years)  wore a FBZ at the non-paretic hip, and were videoed completing a six minute walk test (6MWT). Steps recorded by the FBZ were compared against the criterion standard of manually counted steps from video-recordings. Spatio-temporal gait parameters were calculated, and gait quality was assessed using the Wisconsin Gait Analysis (WGA) tool. Concurrent validity of FBZ was determined using Kendall's Tau correlation coefficient. Linear regression analysis determined the association between gait parameters, quality, and FBZ accuracy. Results: A very strong correlation was observed between the FBZ steps and manual counting (τ = 0.80, p < .001). Step difference demonstrated significant negative association with gait velocity (R2 = 0.35, B = -59.94, p = .007), and positive association with WGA score (R2 = 0.69, B = 4.59, p < .001), indicating poor FBZ accuracy in participants with lower speed (≤0.8m/s) and poor gait quality (WGA score>16). Conclusions: FBZ is an accurate measure of step activity in independent ambulators with stroke walking at speeds > 0.8m/s, but accuracy can be compromised with lower speed and poor gait quality. Clinicians should consider gait velocity and quality before advising FBZ as a motivational tool to increase physical activity in individuals post-stroke.
