This spring provides a high extension force.

Ideal for patients that needs to regain the last degrees of PIP-extension.

The force in the spring can be adjusted by carefully pressing the pads together.

The pressure is distributed by the dorsal pad.

The lower pad provides a slight extension of the MCP-joint.

The force over the joint is approx. 3,4 N in 15 degrees of flexion.
