Effect of NMES on Balance and Fall Risk in Chronic Stroke (NMES)
Chronic Stroke
About this trial
This is an interventional treatment trial for Chronic Stroke focused on measuring functional electrical stimulation, neuromuscular electrical stimulation, walk-training, treadmill training, reactive balance, perturbation, falls, fall prevention

Arms of the Study
Arm 1
Experimental
Effect of functional electrical stimulation on reactive balance and laboratory falls
All individuals will be assigned to the experimental group and will undergo the testing and training procedure across two separate sessions. During the first session, the participants will go through the complete initial screening process. If eligible for the study, the participants will perform the experimental training protocols during the second session. Experimental Protocol The quadriceps, hamstrings, tibialis anterior, gastrocnemius, and the trunk muscle group on the stroke-affected side (weaker side) will be stimulated according to the participant's comfort and tolerance. The range of the intensity allowed by the device is 0-50milliamperes (mA). The frequency of the electrical stimulation device ranges from 1-60Hz.
