Electrical Stimulation, aka IFC or "stim", is like a machine giving you a massage. The four sticky pads are placed around the affected site and a small current (in milliamps) is run through the wires. The patient will feel a small tingling and eventually a light muscle contraction.
Why do we want this?
The purpose of the muscle contraction is to fatigue the muscle until the spasms, guarded tissue, and pain begin to relax. Additionally, the increased muscle contractions serve as a way for blood flow to rinse the inflammation at the injury site. Commonly, the doctors will incorporate ice or heat into this procedure to assist in the anti-inflammatory or relaxation goals.
We often hear snoring or deep breathing because of the amazing relief.
