What does "assistive force" mean?
Muscle Suit for back support strengthens the force of the wearer pivoting his or her upper body relative to his or her lower body (i.e., when stretching out the upper body).
Muscle Suit and Muscle Suit Edge give a maximum of 100 Nm (73.8 ft-lb) for this pivoting force (torque), and Muscle Suit Power gives up to 140 Nm (103 ft-lb). This equates to 25.5 kg (56.2 lb) and 35.7 kg (78.7 lb) of force respectively, at a point 0.4 m (1" 4') away from the rotary joint centered at the waist.
Muscle Upper for arm and back support helps rotary movements in the upper body and shoulders. Users can adjust the balance of torque applied at the arms and back themselves. Muscle Upper produces a total of 140 Nm (103 ft-lb) in torque for arms and back together.
