The OmoTrain S shoulder brace combines compression and medical engineering to provide stability and relief for the shoulder joint in a minimialist style. It guides and centres the arm in the socket so the shoulder maintains proper natural movement, without impacting your mobility. Strapping runs across the shoulder and under the arm, designed to be easy and light to wear. Muscles are activated by medical-grade compression which accelerates blood flow, bringing more oxygen to the shoulder area. This delays onset muscle soreness and accelerates muscle repair. The OmoTrain S shoulder brace is ideal for shoulder arthritis, bursitis, mild instabilities, pain, swelling and tendinitis. Important Note: The primary difference between the OmoTrain S and the OmoTrain is the strapping system. For lighter sprains and milder issues we recommend the OmoTrain S. For stability and dislocation issues, and more severe shoulder pain, we recommend the OmoTrain.
