If you have had a joint replacement, aquatherapy is an amazing way to rehabilitate your joints and strengthen the muscles surrounding them. The water medium will help you improve the range of motion of the joint and therefore walk with a better gait. It will also help you strengthen the major muscles groups in your hip, upper and lower leg, such as quadriceps, hamstrings, hip flexors, gluteus and gastrocnemius muscles.
In my aquatherapy sessions, I have mostly encountered hip and knee replacements, due to the stress that is placed on these joints over a long period of time. The wear and tear can occur from a few factors, including high-impact activities and disease. Doing a variety of physical activities ensures that you remain active but at the same time gives your lower body a chance to rest and recover. Even if you already have a joint replacement, consider alternating high-impact activities with cycling, swimming and aquafitness in order to protect your body from overuse or injury.
