06B - 130 - Electrical Current for Motor Contractions - 2023

Neuromuscular Electrical Stimulation (NMES)

The use of EC (electrical current) produce muscle contractions

Applies only innervated muscles

• innervated muscles

• The muscles still need working nerves

ELECTRODE PLACEMENT AND PATIENT POSITIONING

Patient positioning to maintaain

• midrange

• endrange

What are motor points?

• middle of muscle belly

• end of muscle belly

But when you STOP electrical stimulation they start losing their gains pretty quickly

-Fatigue

-Atrophy

(that's why you encourage the patient to physiologically contract TOGETHER with electrical stimulation!)

• Low twitch

• Fast twitch

Physiological Initiated Contractions

• Slow Twitch

• Fast Twitch

• 4

Neuromuscular Electrical Stimulation (NMES)

Clinical Applications: Control Edema 2/2 Lack of Motion

• if they can't move their muscles and that's the reason they have edema yes

• if they have edema for any other reason

  ex:active injury, systemic illness, kidney failure

ES contractions are ____ the same as physiological contractions

• Are

• NOT

Ap prolonged along motor neurons
