Pattern of muscle activation during wrist extension in participant with SCI and a neurologically intact participant. The neurologically intact participant was able to activate the prime movers during wrist extension and keep the other muscles quiet on both sides, but some participants with SCI were not able to do so and they showed activation of muscles irrelevant to the tasks on both sides even when they had enough strength in their wrist extensor muscles on the active side (3–5/5). WE: wrist extension, MMT: manual muscle testing. R: right, L: left.
