Muscle weakness

Uncharacteristic muscle weakness or inability of the muscles to perform normally, relative to that person’s normal ability.

Definition


Uncharacteristic muscle weakness or inability of the muscles to perform normally, relative to that person’s normal ability.  The symptom will usually be identified when a person is performing exercise or some muscular activity, such as climbing stairs, or carrying goods.  It is however distinct from the weakness (or tiredness) that many will feel when run-down and fatigued as a result of normal activities.

Because muscle contraction requires a signal from the brain, down the spinal cord, to the muscle, the cause of true weakness may lie anywhere along this chain.  It may thus be metabolic, neurological, toxic or directly muscular.
