This EMS elbow brace may help provide temporary muscle stimulation, relaxation, and comfort around the elbow area, but it is not designed to diagnose, treat, or cure radial nerve palsy. Radial nerve palsy is a nerve condition and should be evaluated by a healthcare provider or physical therapist. Please consult your doctor before using EMS, especially if you have numbness, reduced sensation, weakness, nerve injury, or pain. Do not use the device over areas with no sensation, open wounds, swelling, or severe pain.
