What is it? Aquatic therapy, in general terms, is therapy provided in water. More specifically, aquatic therapy is a customized water program designed and monitored by a qualified professional provided to a variety of individuals. It is beneficial in jump starting a therapeutic plan of care for individuals who may not tolerate a land-based program initially, whether that be due to pain, muscle guarding, weight bearing status, etc.
How does it work? The principle of buoyancy is an upward pressure provided to an object in water2. The principle of gravity counteracts the force of buoyancy on an individual in water which allows for decreased weight bearing through the joints and decreased force through the body2. Conversely, on land, 1 pound of weight can make a large impact on the force through the joints of the body. For example, “did you know that 1 pound of weight puts an additional 4 pounds of pressure on knees”1. This is one of the reasons why aquatic therapy is beneficial. The degree of weight bearing in water is dependent on the degree of immersion. For example, an individual has approximately 10% weight bearing in neck deep water and approximately 50% WB in waist deep water2. This principle of decreased weight bearing is one of the most beneficial effects for many populations of individuals. Other benefits of aquatic therapy include muscle relaxation and body awareness provided by the warm water. Also, the drag created by viscosity in water provides a form of resistance training in itself without having to add external resistance such as ankle weights2.
Who does it help? Below is a list of several individuals who may benefit from aquatic therapy (not all encompassing):

  • Individuals with low back pain
  • Individuals who have high pain levels
  • Individuals with muscle guarding
  • Individuals who are post-op (hip replacement / knee replacement / lumbar fusion)
  • Individuals with chronic pain including fibromyalgia
  • Individuals with foot / ankle pain
  • Individuals with obesity who are looking for assistance with weight loss and/or have pain
  • Individuals with neurological conditions
