The EPS is an electric point stimulator. It is considered a tens unit by the FDA, but is a single point of electric current.
Trigger points are a local disruption of the neuromuscular junction, where the motor nerve meets muscle fiber. Electrical stimulation saturates the motor endplate zones in a region with stimulus, causing sarcomere twitch contraction, improved metabolism, reduction of tenderness and hardness.
Typical EPS Treatment Sequence
Assess fiber hardness and tenderness in the muscle prior to treatment.
Locate the approximate center of the fiber bundle you are targeting (motor endplate zone).
Press the treatment button, move the skin with the point to locate most effective motor effect zone.
If the client has no sensation, skin is very dry or amplitude is too low.
Treat 10-20 secs. per point. After every 1-3 points, do a contract/relax.
Monitor any tissue change produced by the treatment - hardness, tenderness.
