Muscle strength rating scale

The table below is accepted by the British Medical Research Council. There is a more common variant, the data for it are given in parentheses.

Our systems are applicable, for diagnosis of any muscle condition on this scale. For rehabilitation without additional devices, you need 3 or more points. If the passive movement or movement in one plane is complemented by an bodybar or elastic band, then the training can also be performed with a zero grade.
