Summary

Following stroke, muscle weakness and impaired motor function are expressed in both the more (MA; paretic) and less affected (LA; non-paretic) sides. Although the efficacy of resistance training is well recognized, training the MA limb directly may be initially difficult due to muscular weakness. "Cross-education" is training one side of the body increases strength in the untrained and opposite side. This concept can be applied in strength training when training the more affected sides cannot be initiated. Recently, our lab found six weeks of dorsiflexion resistance training in the LA leg improved the strength of both trained and untrained legs of chronic stroke participants.

The current project explored if cross-education exists in the upper limb in chronic stroke participants and if there are related changes in cortical and spinal cord plasticity. We hypothesized that unilateral strength in the less affected arm could enhance wrist extension strength bilaterally with related neural adoption and improved clinical function.

DEVICE

Unilateral wrist extension training

Participants will join a five-week training protocol with 3 sessions per week. During each session, 5 sets 5 maximal wrist extension training will be performed on participants less affected side.
