What is Muscle Tension?
Mike Squirrell Physiotherapy Harley Street, London W1 are here to help treat your Muscle Tension.
Unconscious nerve impulses maintain the muscles in a partially contracted state. If a sudden pull or stretch occurs, the body responds by automatically increasing the muscle’s tension, a reflex which helps guard against danger as well as helping to maintain balance.
The presence of near-continuous innervation makes it clear that tonus describes a “default” or “steady state” condition. There is, for the most part, no actual “rest state” insofar as activation is concerned.
In terms of skeletal muscle, both the extensor and flexor muscles, under normal enervation maintain a constant tone while “at rest” that maintains a normal posture.
Cardiac muscle and smooth muscle, although not directly connected to the skeleton, also have tonus in the sense that although their contractions are not matched with those of antagonist muscles; their non-contractive state is characterised by (sometimes random) enervation.
