Atrial fibrillation and a corresponding enlargement of the left atrium may cause an increase in size of the mitral valve annulus. With a sinus rhythm, the mitral annulus undergoes dynamic changes during the cardiac cycle. For example, at the end of diastole the annular area is smaller than at the end of systole.
To determine who can perform aquatic therapy, we must define what aquatic therapy is. First, notice that aquatic therapy is considered a therapeutic procedure, not a modality. There are many technical and practical distinctions between the practice of aquatic therapy and the application of therapeutic modalities.
Aquatic Therapy is therapy that is done in a pool, preferably in warm water, to restore movement and strength through the use of heat, buoyancy and resistance. It aims to rehabilitate clients after injury or those with chronic illness, avoiding the amount of weight placed on the joints by exercise out of the water.
