Hand and wrist supports are orthopedic devices designed to stabilize small joints, limit excessive motion, and reduce mechanical stress on tendons, ligaments, and surrounding soft tissues. By controlling flexion, extension, and rotational forces, these braces promote proper joint alignment while preserving essential hand function. O’tessy hand and wrist orthoses are developed based on biomechanical principles to support recovery in cases of sprains, tendon strain, repetitive stress injuries, carpal tunnel syndrome, post-traumatic conditions, and post-operative rehabilitation. Depending on the required level of stabilization, models range from elastic compression sleeves to splinted designs that provide structured immobilization.
