Balance and physical Therapeutics

WalkAide is a medical device that has received marketing clearance from the FDA for improving the walking ability of people experiencing foot drop from upper motor neuron dysfunction. WalkAide simulates the typical nerve-to-muscle signals in the leg and foot, which causes the foot to lift at the appropriate time in the walking cycle. This results in a smoother, more natural, and safer stepping motion. WalkAide is not a one size fits all device. Rather, a specially trained medical professional is required to fit and customize WalkAide for you. Using WalkAnalyst, a multifaceted computer software program, the clinician will tailor WalkAide to your individual walking pattern for optimal effectiveness.

How does Balance Therapeutics use the WalkAide System?

We specialize in caring for patients that suffer from foot drop caused by Multiple Sclerosis, incomplete SCI, TBI and Stroke/Cardiovascular Accident (CVA). With certified physical therapists to assist in the proper use of this device, proper candidates for this device will experience a greater, more active quality of life.


Here at SSNA Balance and Physical Therapeutics, we participate in many research studies in order to further advances in the physical therapy field. By participating in these programs, we are providing the newest therapies to our patients. Two of the studies that we have recently participated in are:

  • The RACE Study in conjunction with Dartmouth University to study the effects of adding reactive balance treatment to improve balance and reduce falls in the older population.
  • INSTRIDE Study in conjunction with Innovative Neurotronics Inc. to examine the effectiveness of the WalkAide stimulus unit versus a standard ankle foot orthotics in the treatment of foot drop.
  • Future research in conjunction with Touro College Physical Therapy department to study the effects of the LSVT Big Intervention program on individuals with PD
