Generally, hypertonic muscle occurs in the large paraspinal muscles, which hold the spine “up” against gravity – They allow us to bend forward (flex) backwards (extend) sideways and to rotate. When any of these muscles become hypertonic there are a number of other muscles that become Hypotonic – extend and weaken. The usual ones are abdominal, hip, and thigh muscles.
Once things progress just this far it takes very little to set off an acute back pain episode. Reaching for something when your body is slightly turned, bending over to pick up something small, a little weekend gardening or game of golf. That’s all it may take. Suddenly, semi-contracted muscles now go into full contraction – that’s muscle spasm and the cause of the excruciating pain that “lays you out” – also referred to as an “Acute Pain Episode.”
