A therapy pool at an Omaha medical center aims to help rehabilitation patients.

The 55-by-44-foot pool at Alegent Creighton Immanuel Medical Center has a floor that adjusts the water depth. The buoyancy of the 90- to 93-degree water also helps patients increase strength and muscle tone, as well as range of motion.

Outpatient classes help with conditions like arthritis, back pain, orthopaedic injuries, sports injuries and neurological or muscle deficit. Officials say the pool also benefits patients who use wheelchairs since the bottom of the pool can be raised and lowered.
