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.
