High intensity strength training improves strength and functional performance after stroke

Objective: To evaluate the effects of a progressive resistance strength tra ining program on changes in muscle strength, gait, and balance in older ind ividuals 1 yr after stroke, seven individuals were recruited who were great er than 60-yr-old, 1 yr after stroke, living at home, and able to follow ve rbal commands. Design: Subjects participated in a 1 2-wk 2X per wk resistance training pro gram at 70% of 1 repetition maximum. Results: Lower limb strength improved 68% on the affected side and 48% on t he intact side during training, with the largest increases observed for hip extension (affected side: 88%, P < 0.01; intact side: 103%, P < 0.001). Re peated chair stand time decreased 21% (P < 0.02). Motor performance assesse d by the Motor Assessment Scale improved 9% (P < 0.04) and static and dynam ic balance (Berg balance scale) improved 12% (P < 0.004). Progressive resis tance training in individuals 1 yr after stroke improves affected and intac t side lower limb strength and was associated with gains in chair stand tim e, balance, and motor performance. Conclusions: These results support the concept that strength training is an appropriate intervention to improve the quality of physical function in ol der community dwelling stroke survivors.
