Short-term and long-term effects of a progressive resistance and balance exercise program in individuals with chronic stroke: a randomized controlled trial

AbstractPurpose: To evaluate the effects of progressive resistance and balance (PRB) exercises on physical and psychological functions of post-stroke individuals.Materials and methods: In a randomized controlled trial with follow-up at 3, 6 and 15 months, 67 community-living individuals (76% male; 65–85 years) with a stroke 1–3 years previously were allocated to an intervention group (IG, n = 34; PRB exercises combined with motivational group discussions twice weekly for 3 months) or a control group (CG, n = 33). The primary outcomes were balance (Berg Balance Scale, 0–56 points) and mobility (Short Physical Performance Battery, 0–12 points) at 3 months. The secondary outcomes were 10 m comfortable walking speed, physical activity levels, health-related quality of life, depression and fall-related self-efficacy.Results: At 3 months, the IG exhibited significant improvements in balance (MD 2.5 versus 0 points; effect size [ES], 0.72; p < 0.01) and comfortable walking speed (MD 0.04 versus -0.05 m/s; ES, 0....
