The elbow is not a simple hinge joint. In addition to flexion and extension, the elbow can pronate and supinate.

Elbow Extensionater®

Different elbow injuries require the forearm to be positioned differently when stretching. The unique design of the Ermi Elbow Extensionater improves elbow extension while allowing perfect forearm alignment, no matter the injury.

The Elbow Extensionater is designed based on the principle of three-point bending. It is a small, easy-to-use device that uses a patented pneumatic air bladder technology to improve extension.
