RESUMO
PURPOSE OF THE STUDY After the surgical treatment of injuries of the lower extremities or osteotomies, patients are frequently asked to partially load the affected leg during the first weeks of rehabilitation. The patient's compliance to the prescribed weight bearing limit and their ability to regain a physiological gait as soon as possible are necessary for a fast rehabilitation without complications. MATERIAL AND METHODS/RESULTS To support patients during this important phase of recovery, we developed a feedback and analysis system that is able to provide feedback concerning loading and roll over behavior to the patient. The system is based on sensor insoles to measure the amount of pressure and pressure distribution and on a smartphone application to provide realtime visual and acoustic feedback. CONCLUSIONS This newly developed device has the potential to monitor the rehabilitation phase and assist patients with lower leg injuries therefore decrease the complication rate and enable faster rehabilitation. Key words: lower limb fracture osteotomy around the knee, partial weight bearing, realtime feedback, smartphone application.
