Pool therapy is a useful method of treatment for the disabled. It has many advantages to exercise in water. The properties of buoyancy and turbulence offered by water enable the disabled not only to move with greater freedom, but may also make it possible to execute movement which would not be possible on land; furthermore, the equal pressure of water on all aspects of submerged body will support it in the upright position and this support helps to induce relaxation and to relieve pain. As the warmth of the water dilates the surface vessels and increases blood supply to skin, particularly in patiens with poor peripheral circulation. Combined with the effect of heat, buoyancy enables a greater range of joint movement to be achieved. With the' weight relief' of buoyancy, pool therapy will give confidence to a patient who has difficulty in walking, and indeed may enable him to walk in the pool before he can do so on land. Swimming is a particularly useful recreation activity. The different strokes use a wide variety of muscles, and many patients who are severely handicapped out of water are mobile in pool. Once the disabled can swim, the opportunities for socialization are enhenced both in family and amongst the disabled peers. Besides the therapeutic effect, pool therapy is of great psychological value.
