Electromyography (EMG) is a test that detects electrical activities within muscles. It allows the measurement of muscle responses as triggered by the stimulation of the appropriate nerves. When the measurements are displayed, either visually or audibly, the evaluation of the measured variable can be made. This process is called "biofeedback". The EMG provides biofeedback based on the relationship between the tension and the relaxation of the muscle. Electrodes/probes are placed over the chosen muscle/muscle group. The electrical signals detected are proportionate to the actual activities of the stimulated muscle, thus representing/portraying the actual strengths and weaknesses of the muscle. The electrical measurements expressed in microvolts are subsequently interpreted to form the basis of the diagnosis. Correct diagnosis enables the implementation of the appropriate "needs based" neuromuscular stimulation programs for effective muscle re-education and rehabilitation. An extra benefit of paramount importance presented by the EMG Biofeedback is that it allows the patients to verify and visualise their own situation and to facilitate their own progress, thus providing ongoing motivation and encouragement.

EMG Biofeedback therapy is used very successfully by health professionals throughout the world in the evaluation and the treatment of a growing number of conditions, such as:
· Patellofemoral Pain Syndrome
· Myofascitis
· Myofacial Pain
· Neck and Shoulder Girdle Pain
· Repetitive Strain Injury

EMG triggered Stimulation (ETS) enables patients to trigger neuromuscular stimulation that is appropriate to their muscle status.
Neuromuscular Stimulation is used for the following purposes:
· Increase muscle strength
· Maintain or improve range of movements
· Increase and improve blood supply to the muscle
· Warm up prior to exercising
· Alleviate muscle spasm
· Change muscle tone
· Prevent disuse atrophy
· Pain relief

Neuromuscular Stimulation can be described as a low volt stimulation of motor nerves that causes a muscle or a group of muscles to contract. Contraction/relaxation of muscles has been found effective in a treatment of many vascular conditions and musculoskeletal disorders as listed above.
