The most common problem is internal rotation contracture (permanent muscle contraction) of the shoulder.
The contracted state, instead of rapidly subsiding after discontinuance of the stimulus, slowly and only partially wears off, the muscle remaining in a condition of physiological "contracture."
contracture of the PIP joint with hyperextension of the MTP joint.
We make hand & elbow splints to prevent contracture.
The rolls are not designed for use with people who have significant contracture or deformity.
