Electromyography (EMG, muscle function assessment), gastrocnemius soleus complex

We use EMG (electromyography) to examine muscle activity in order to assess muscle function and identify any disorders. With the EMG we focus on the gastrocnemius muscle, which is also known as the lower leg muscle or calf muscle. This muscle controls the bending and twisting of the foot, and allows us to flex our feet. As a result, this muscle plays an extremely important role when running, jumping and walking, as well as when riding a bicycle.

We measure the muscle when fully and gently tensed, as well as when it is at rest, by sticking electrodes to the muscle that measure the tension. If the muscles or nerves are damaged, this will show up in the muscle activity.
