Effectiveness and feasibility of eccentric and task-oriented strength training in individuals with stroke

BACKGROUND: Strength training can increase function in individuals with stroke. However it is unclear which type of strength training is most effective and feasible.OBJECTIVE: To assess the effect and feasibility of an intervention combining eccentric and task-oriented strength training in individuals with chronic stroke.METHODS: Eleven participants were randomly assigned to a group first receiving four weeks of eccentric strength training and then four weeks of task-oriented strength training (EST-TOST) or vice versa (TOST-EST). Strength and upper limb function were administered with a hand-held dynamometer (HHD) and the Action Research Arm Test (ARAT) respectively. Feasibility was evaluated with the Intrinsic Motivation Inventory (IMI), the adherence and drop-out rate.RESULTS: Significant increases were found in ARAT score (mean difference 7.3; p <0.05) and in shoulder and elbow strength (mean difference respectively 23.96 N; p <0.001 and 27.41 N; p <0.003). Participants rated both EST and TOST with 81% on the IMI, the adherence rate was high and there was one drop-out.CONCLUSION: The results of this study show that a combination of eccentric and task-oriented strength training is an effective and feasible training method to increase function and strength in individuals with chronic stroke.
