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.
