The Wilmer Stretching Orthosis, abbreviated WSO, is a lightweight arm orthosis (also called brace or splint) from the Wilmer line, developed at Delft University of Technology. The orthosis helps to stretch the arm through an adjustable spring mechanism.
Who is the Wilmer Stretching Orthosis for?
The WSO is designed for individuals who have difficulty stretching (extending) their elbow. Limited elbow extension can lead to reduced arm function, pain, and discomfort. If the arm remains in a bent position for an extended period, the muscles may shorten, further limiting mobility. This condition is known as a contracture.
