“In the basement of the Egan Research Center at Northeastern University, a group of students are toiling away under the watchful eye and guidance of professor Constantinos Mavroidis to build a rather unique device called the Virtually-Interfaced Robotic Ankle and Balance Trainer — or vi-RABT. For the better part of a year the team has been working on what started life as a Capstone project. The concept began when Dr. Maureen Holden, from the school’s physical therapy department, came to the laboratory with a problem: how can we improve the speed and quality of recovery for stroke patients who have lost strength in their ankles and struggle to stay balanced?”

“Devel­oped in Mavroidis’ Bio­med­ical Mecha­tronics Lab­o­ra­toryin col­lab­o­ra­tion with Holden’s lab in phys­ical therapy, the vi-​​RABT device is equipped with two inde­pen­dent foot plat­forms that can rotate with two degrees of freedom and are con­stantly col­lecting data through a host of pres­sure sen­sors embedded within. Because vi-​​RABT can apply both assis­tive and resis­tive forces to the foot, it can be used across the range of physical-​​therapy treat­ment protocols.”

“An estimated two and a half individuals out of every 1,000 suffer ankle sprains each year in the U.S., which translates to more than 750,000 people. As the number of stroke patients increase, this type of injury will require a cheap and more effective form of therapy. The team predicts it will have a commercially viable vi-RABT costing around $10,000 in about two years, which is considerably less than similar systems that can run up to $60,000.”
