Effect of NMES on Spasticity

The goal of this clinical trial is to learn if neuromuscular electrical stimulation (NMES) works to treat spasticity in adult patients with spasticity related to stroke. The main question it aims to answer is: • Does NMES reduces the severity of spasticity? Researchers will compare NMES treatment to baseline and non-stimulation periods to see if NMES works to treat spasticity. Participants will: • first undergo an initial assessment at 10-minute intervals for one hour, followed by 20 minutes of NMES exposure, and subsequent post-treatment assessments at 10-minute intervals for two hours. This daily procedure will be repeated over four days for one patient, and performed only once for the remaining three patients.
