Effect of Exercise Interventions on Health-Related Quality of Life After Stroke and Transient Ischemic Attack: A Systematic Review and Meta-Analysis

Exercise interventions have been shown to help physical fitness, walking and balance after stroke, but data is lacking on whether such interventions lead to improvements in health-related quality of life (HRQoL). In this systematic review and meta-analysis, thirty randomised controlled trials (n=1,836 patients) were found from PubMed, OVID MEDLINE, Web of Science, CINAHL, SCOPUS, The Cochrane Library and TRIP databases when searched from 1966 to Feb 2020, that examine the effects of exercise interventions on HRQoL after strokem or transient ischaemic attack (TIA). Exercise interventions resulted in small to moderate beneficial effects on HRQoL at intervention end (standardised mean difference (SMD) -0.23; 95% CI -0.40 to -0.07) that appeared to diminish at longer term follow up (SMD -0.11; 95%CI -0.26 to 0.04). Exercise was associated with moderate improvements in physical health (SMD -0.33; 95% CI -0.61 to -0.04) and mental health (SMD -0.29; 95% CI -0.49 to -0.09) domains of HRQoL while effects on social or cognitive composites showed little difference. Interventions that were initiated within 6 months, lasted at least 12 weeks in duration, involved at least 150 minutes per week, and included resistance training appeared most effective. Exercise can lead to moderate beneficial effects on HRQoL and should be considered an integral part of stroke rehabilitatio

Danish translation and psychometric testing of the Rivermead Mobility Index.

OBJECTIVES: The Rivermead Mobility Index (RMI) is widely used in several neurological conditions including multiple sclerosis (MS), but its psychometric properties have not been documented in Scandinavia. Therefore, the aim of the study was to translate RMI from UK English into Danish and conduct an initial psychometric testing of the Danish RMI. MATERIALS AND METHODS: The Danish translation conducted by the forward-backward method was first field-tested regarding user-friendliness and relevance. It was then psychometrically tested among 40 outpatients with MS regarding unidimensionality (corrected item-total correlations, adherence to an assumed Guttman response pattern), reliability, and construct validity. RESULTS: Field testing found the Danish RMI relevant and user-friendly. Corrected item-total correlations were ≥0.47 and item responses fitted the Guttman pattern. There was a 47.5% ceiling effect, and reliability was 0.91. Correlations supported construct validity. CONCLUSION: The Danish RMI is user-friendly, unidimensional, reliable, and valid. The results correspond to those previously reported with the original UK RMI version. Ceiling effects are limiting but sample related. Larger samples representing a wider variety of MS severities are needed for firmer evaluation of the Danish RMI
