Introduction
In general, the effectiveness of a physical therapy device for shoulder periarthritis depends on the stage of the condition. It is usually effective during the remission phase, but may have limited benefit or even cause discomfort during the acute phase. To maximize the therapeutic effect and maintain shoulder health, it is recommended to first determine the current stage of shoulder periarthritis and then select an appropriate type of physical therapy device. Daily activities should avoid overuse or excessive strain on the shoulder.
Generally, the effectiveness of physical therapy devices for shoulder periarthritis depends on the stage of the condition. They are usually effective during the remission phase but may be ineffective or even cause discomfort during the acute phase. Detailed analysis is as follows:
If shoulder periarthritis is in the remission phase—characterized by mild pain and minimal restriction of movement—using a physical therapy device can help improve local blood circulation, relax tense muscles, relieve shoulder stiffness, and enhance joint mobility, thereby positively supporting symptom recovery.
However, if the condition is in the acute phase, with severe pain and obvious swelling, using certain physical therapy devices may increase local congestion and edema, worsening pain. This not only limits therapeutic benefits but may also prolong the acute phase; therefore, use is not recommended at this stage.
To maximize the benefits of physical therapy devices and maintain shoulder health, it is advisable to first determine the current stage of shoulder periarthritis and then select an appropriate type of device. Daily precautions should include avoiding excessive shoulder strain, performing moderate shoulder stretching exercises, keeping the shoulder warm, and minimizing the risk of recurrence or aggravation of shoulder periarthritis.
