- Weights of our participants are presented in column 2. For FF20% (column 3), the sign of the peak power is positive as the orthosis applied torque in the same direction as ankle movement. For FF50% (column 4), peak power is negative as the orthosis applied torque in the direction opposite to the ongoing movement. In both cases however, subjects had to produce more energy to resist the force field.
