Exercise apparatus and technique

摘要

To provide controlled amounts of resistance to movement in exercise equipment or in orthotic devices, a control module has cooperating resistance elements. The force between the elements is varied in accordance with the position of the elements with respect to each other. For example the control module can connect two splints of a knee brace so that the resistance to flexion and extension are programmed in accordance with the position of the leg and thigh with respect to each other.
