OmoTrain is a unique shoulder support that promotes mobility and limits rotation. The modern, breathable knitted material makes the support extremely comfortable to wear. A persistently painful shoulder will tend to stiffen up over time as a result of protective positioning. This is where targeted exercise therapy, supported by an active support, can help. OmoTrain, the support used for posttraumatic and postoperative shoulder pain and osteoarthritis of the shoulder, optimizes shoulder joint control and counteracts painful rotary movements. The individually positionable viscoelastic profile insert improves circulation locally through continuous massage for faster reduction of swelling and effusions. With consistent use, OmoTrain helps accelerate mobilization of the injured shoulder and produces noticeable pain relief. Knitted shoulder support incorporating an adjustable, anatomically contoured silicone insert. Unique design guides and centers the arm in the socket promoting mobility but inhibiting rotation. Silicone insert provides intermittent compression to the soft tissue of the joint, which increases circulation, and helps decreases pain and swelling. Anatomical knit with graduated compression at the edges to prevent constriction of circulation. Can be used on either the right or left shoulder. Can be used to treat: Shoulder pain (posttraumatic, postoperative), Post-operative rotator cuff rehabilitation, Shoulder subluxation, Arthritis. Post-arthroscopic surgery, Nerve Palsy.
