Gait dysfunction in those with trans-femoral and trans-tibial limb loss can lead to degradation of the intact and surgical limb, causing a risk of osteoarthritis and decreased bone density. Those affected with lower limb loss are still rising in number, and gait deviations remain a significant factor in function and quality of life for these individuals. Chronic compensation from dysfunctional gait patterns have been shown to have additional consequences of low back pain and increased energy cost. Real time visual feedback follows the motor learning theory that internalization of a new neuromuscular pattern is enhanced when the patient’s focus is directed externally. We developed a system to provide real time mobile visual feedback (MOVISU-FIT) for gait training using kinetic data derived from the user’s prosthetic limb itself and displayed wirelessly to smart glasses. Creating mobility in combination with real time knowledge of performance during gait training with MOVISU-FIT enhanced automaticity therefore retention beyond the initial frame of rehabilitation.
Our goal was to develop, and assess the feasibility and efficacy of, a gait training system that provided real time visual feedback derived from kinetic sensor data within the prosthetic limb and was mobile and wearable for those with lower limb loss. The development then allowed preliminary pilot data analysis of the efficacy of this type of training on gait performance (symmetry and frontal plane pelvic motion), pain and functional measures. In addition, this project and its findings expanded our ability to assess the impactful factors on not only this type of training and feedback, but also on gait parameters that were retained beyond the end of training in this patient population.
