1. An exercise device comprising:
- a first member adapted to be connected to one limb about a joint;
a second member adapted to be connected to another limb connected to the same joint as the one limb wherein the first and second members articulate about the joint;
a module connecting the first and second members and controlling the force necessary to articulate the first and second members;
said module including a braking means, a feedback means and friction means for resisting movement of the first and second members with a frictional force independent of speed of movement which frictional force is varied by said braking means;
said feedback means including means for energizing and de-energizing the braking means at the different angles between the first and second members, wherein the braking means is controlled by the position of the first and second limbs to provide for a first series of first periods of time having a first frictional force and a series of second periods of time having a second frictional force during which second periods of time each of the limbs can be moved;
the first periods of time being separated from each other by said second periods of time.

Abstract
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.
