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

Patients recovered an average of 15 degrees of elbow extension in five weeks, with most recovering full extension.

“I started using your product after surgery and have found it to be a great addition to my recovery. It has definitely helped me when I was not making the progress I wanted. This product speed up my recovery and allowed me to gain both flexion and extension faster then I was making in therapy alone.”

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.
