Important Things to Know About Aquatic Therapy


  • You do not have to know how to swim to participate!  You do not have to wear a swimsuit!  Excercise clothing or Shorts and a t-shirt are fine!
  • Your therapist will be in the water with you at all times. This is beneficial for those who may be nervous about getting in the water. It is common for patients to feel a significant increase in ability, confidence and morale, within a few therapy sessions. 
  • The buoyancy of water can actually decrease weight bearing by up to 90 percent. This means that if you are unable to support your weight on land, you will likely be able to stand in the pool without risk of falling. 
  • Water exercise provides resistance that can help improve your strength and cardiovascular fitness while stimulating body awareness, balance and stability. 
  • There are many benefits associated with submersing your body in warm water. Patients commonly experience muscle relaxation, increased circulation and decreased pain and swelling.

Aquatic therapy is not a group exercise class!  It is a one-on-one customized treatment session with a licensed therapist that is performed in a warm water pool. 


Aquatic therapy uses the physical properties of water to assist in patient healing and exercise performance.  One of the most important benefits of 
aquatic therapy is the buoyancy provided by the water. While submerged in water, buoyancy assists in supporting the weight of the patient. This decreases the amount of weight bearing which reduces the force of stress placed on the joints. This aspect of aquatic therapy is especially useful for patients with arthritis, spinal or joint issues, back pain, fibromyalgia,  chronic pain, healing fractured bones, or who are overweight. By decreasing the amount of joint stress it is easier and less painful to perform exercises.

The viscosity of water provides an excellent source of resistance that can be easily incorporated into an aquatic therapy exercise program. This resistance allows for muscle strengthening without the need of weights. Using resistance coupled with the water’s buoyancy allows a person to strengthen muscle groups with decreased joint stress that cannot be experienced on land.

Aquatic therapy also utilizes hydrostatic pressure to decrease swelling and improve joint position awareness. The hydrostatic pressure produces forces perpendicular to the body’s surface. This pressure provides joint positional awareness to the patient. As a result, patient proprioception is improved. This is important for patients who have experienced joint sprains, as when ligaments are torn, our proprioception becomes decreased. The hydrostatic pressure also assists in decreasing joint and soft tissue swelling that results in injury or with arthritic disorders.

Lastly, the warmth of the water experience during aquatic therapy assists in relaxing muscles and vasodilates vessels, increasing blood flow to injured areas. Patients with muscle spasms, back pain, and fibromyalgia find this aspect of aquatic therapy especially therapeutic.
