1. Recovery treatment: This device disperses and provides an upward pulling force to raise the arm and reduce shoulder pressure. It is suitable for shoulder injury , shoulder joint reduction, humeral fracture fixation, and shoulder abduction recovery. 2. Arm elevation at 1 or 2 points: Elevating the arm at these points reduces the sliding force of the shoulder and helps prevent pain caused by shoulder sliding or external loading. 3. Pivot point design: With 3 or 4 pivot points, the shoulders are pulled with the chest as the pivot point, avoiding direct pulling of the arms and reducing load on the shoulders. 4. Fulcrum lift: Four fulcrums lift upward to increase the lifting force and raise the entire shoulder. Suitable for shoulder dislocation, shoulder sprain, shoulder subluxation, and hemiplegia caused by stroke. Use scenarios Postoperative rehabilitation for shoulder or humeral fracture fixation, to support safe lifting and reduce shoulder stress during recovery. Acute shoulder injuries such as dislocation or sprain, to assist rehabilitation and alleviate pain from movement. Strokerelated hemiplegia affecting the shoulder, to aid arm elevation and support shoulder stability during therapy.
