Nerve Stimulation System Helps Paralyzed Patients Practice Walking
In recent years, research on treating complete paralysis due to spinal cord injuries has been significant, but research on treating incomplete paralysis in patients with less-severe injuries or conditions like multiple sclerosis has fallen by the wayside. Now, however, an electrical stimulation system for the nervous system is helping patients with partial paralysis walk and even run, giving them improved health and a new lease on life.
The neurostimulation systems are designed to treat foot drop, a condition that occurs in patients with partially-paralyzed legs, hips, or feet. Foot drop happens when the brain signals the leg to lift up to take a step, but it can only respond partially due to the paralysis. Patients with foot drop often have difficulty walking because the leg and foot don’t lift or move far enough forward for the patient to stay balanced. Falls are common in foot drop patients, which can increase their risk of injury.

Once upon a time, physical therapy for patients paralyzed by spinal cord injuries wasn’t a part of most treatment plans. Keeping the muscles toned when patients couldn’t use them didn’t seem necessary, and it often gave patients false hope that they would someday regain the use of their paralyzed limbs. Today, however, physical therapy for paralyzed spinal cord injury patients is used increasingly to keep muscle tone going, improve immune system function, and prepare patients for the possibility that treatments might improve their own ability to use their limbs again.
