PCMS Task After Moderate-to-severe Stroke
United States51 participantsStarted 2023-03-29
Plain-language summary
Researchers at the University of Pittsburgh are conducting a research study to see how combining brain, nerve, and hand stimulation affect hand movement after stroke. The primary purpose of this study is to examine changes in the connection between the brain and the weak hand muscles after the combined brain, nerve, and hand stimulation. The primary hypothesis is that the combined brain, nerve, and hand stimulation will increase the the connection between the brain and the weak hand muscles. The secondary purpose of this study is to examine changes in weak hand's movement and function after the combined brain, nerve, and hand stimulation. The secondary hypothesis is that the combined brain, nerve, and hand stimulation will increase weak hand movement and function.
