PMA act as a contraction ,actuator, if the braided angle is less than 54.70, and the ,extension actuator, if the angle is more than 54.70. Moreover, the PMA will produce a pulling force for contractor type and a pushing force for the extensor one. Important researches have been done to define the contraction force of the ,pneumatic, muscle actuators.
