Low Back Pain - Hip Pain - Adduction
By Jennifer Chu

Patients with lower back pain from irritation of the L5 and S1 nerve roots often have weakness from pain and spasm in the hip abductor muscles and the hip extensor muscles. This allows for imbalanced contraction of the hip adductor muscles since the opposition muscles are weak.

The hip adductors then become tight and shortened. This creates an even more unfavorable condition for the already weakened hip abductor and hip extensor muscles which must contract against tight and shortened hip adductor muscles. This creates a vicious cycle perpetuate the lower back pain symptoms.

The hip adductor muscles are:
- adductor magnus
- adductor brevis
- adductor longus

These muscles are supplied by the obturator nerve from L2, L3 and L4 nerve roots. The adductor magnus is also supplied by the sciatic nerve (L4, L5, S1).

Other muscles that also perform hip adduction are:
- gluteus maximus (lower fibers)
- quadratus femoris.

Gluteus maximus is supplied by the inferior gluteal nerve (L5, S1 especially S1 nerve root). Quadratus femoris is supplied by the nerve to the quadratus femoris from the sciatic nerve (L4, L5, S1).

Jennifer Chu, M.D. emeritus professor of Physical Medicine and Rehabilitation, School of Medicine, University of Pennsylvania, pioneered eToims Twitch Relief Method that utilizes surface electrical stimulation to locate motor points (trigger points). The motor points are then stimulated to induce strong local muscle contractions, termed twitches. This results in reduced muscle pain and discomfort in the areas that were stimulated. The involved pain/discomfort-relieving mechanism is thought to include local muscle exercise and stretch effects.

eToims Soft Tissue Comfort Center® specializes in diagnosis and treatment which ends muscle discomfort and pain.
