Aquatic Therapy

Water can make exercise easier and less painful because it removes excessive forces on joints. Johns Hopkins Rehabilitation Network has two adult aquatic therapy locations in Maryland and Washington, D.C., and one pediatric therapy program at Kennedy Krieger Institute in Baltimore. At each of these clinics, you will receive a physical therapy plan tailored to your health concerns and based on the latest aquatic therapy research and guidelines. Aquatic-based physical therapy is usually two to eight visits with the goal of progressing to land-based rehabilitation.

Benefits of Aquatic Therapy

Aquatic exercises can help with early weight bearing, balance training, flexibility, as well as strengthening the core back muscles and improving gait. The physical properties of warm water have many therapeutic benefits.

Easy on the Joints

Buoyancy decreases weight bearing and lessens impact on joints, allowing you to perform exercises that may be difficult to do on the ground.

Less Pain

Warm water helps reduce pain by relaxing tight or spasm-prone muscles and increasing blood flow.

It's Fun

Aquatic therapy offers an engaging therapy environment that uses water’s natural resistance and buoyancy, making therapy more fun and enjoyable.


Conditions That May Benefit from Aquatic Therapy

Exercising in a pool without carrying your full body weight can help you ease into activity and start rehabilitation earlier after an injury or surgery. This is also a great way for athletes to maintain conditioning.

  • Gait deviations and balance difficulties
  • Sprains and strains
  • Low-back pain and spinal disorders
  • Neurological disorders
  • Sports injuries and orthopaedic trauma
