Isotonic concentric contraction (for toning or rehabilitation)


Toning weakened musculature.

Contraction starting point

In a mid-range easy position.

Modus Operendi

The affected muscle is allowed to contract, with some constant resistance from the operator.


The patient’s effort overcomes that of the operator since the patient’s force is greater than the operator’s resistance.  The patient uses maximal effort available, but force is built slowly, not via sudden effort.  The operator maintains a constant degree of resistance.


3-4 seconds


Repeat 5-7 times, or more if appropriate.
