Spinal cord injury patients have been using underwater treadmills as part of research at Middle Tennessee State University.
Patients have noticed improvements in their movement and one even walked out of the laboratory without his crutches as his balance and muscle tone had improved so much, Tennessean.com reported.
"They're walking faster, their endurance is better, their aerobic fitness is up, it's just a better quality of life," said researcher Sandy Stevens.
The scientists believe that, even when the connection between the brain and the spinal cord is damaged by a spinal injury people can learn to walk again through a primal reflex.
Ms Stevens told the website that patients do well on the aquatic treadmills as they do not need to worry about falling over so they can concentrate more on what they are doing. Also, the buoyancy of the water helps to support weight and alleviates pressure on joints.
Recent research, published this month in the journal Archives of Physical Medicine and Rehabilitation, found that 48 per cent of spinal cord injury patients who use wheelchairs have had to have their chairs repaired.
