What is the primary function of a whirlpool in physical therapy?

The primary function of a whirlpool in physical therapy is to provide a heating effect. Whirlpool baths are designed to deliver both thermal and mechanical effects to the tissues immersed in the water. The warmth generated by the water helps to elevate tissue temperature, which can assist with pain relief, increase circulation, and promote muscle relaxation. The buoyancy of the water also reduces the weight-bearing stress on joints and soft tissues, making it easier for patients to move within the whirlpool.

In addition to the heating effect, the agitation and movement of the water can stimulate circulation, promote relaxation, and enhance the effectiveness of exercises performed in the water. While the therapeutic benefits can assist with mobility and exercise, the fundamental role of a whirlpool focuses on the heating and soothing attributes provided by the warm water.
