Muscle Stimulator is an adjunct physical therapy modality often used to reignite muscles' ability to contract. Enhancing muscle contraction may help you control pain, get stronger, increase physical functioning, retrain movements you may have lost, and/or manage inflammation. This stimulator uses electrical impulses to cause muscles to contract, which in turn helps your muscles become stronger. Muscle Stimulator contains small electrodes that send electrical pulses through your skin when you secure the device around your midsection. The benefits of using a stimulator are a result of the electrical currents that pass through the body, which is why these are also known as electrical muscle stimulation devices.
