Assessment of the Impact of Treadmill Training with Digital Biofeedback on Functional Performance and Gait Parameters...

Background: Gait re-education is one of the key elements of comprehensive rehabilitation after total hip replacement. Recent technological advancements allow patients to benefit from increasingly sophisticated training solutions based on biofeedback. The aim of this study was to assess the impact of a treadmill training protocol with a digital biofeedback component on the gait parameters of patients after an uncomplicated total hip replacement and on their functional status. Methods: The study included 137 patients after total hip replacement. In the control group, traditional walking training with biofeedback in the form of a mirror was used. In the study group, the Biodex Gait Trainer 3 treadmill was used for this purpose, which also served as a diagnostic tool for both groups. The following parameters were assessed: distance, average walking speed, average step cycle, step length, coefficient of variability and time on each foot. Additionally, the study included the Timed Up & Go (TUG) test and the use of orthopedic supplies. Results were considered statistically significant at p < 0.05. Results: Significant statistical differences were found between the groups in terms of distance, average walking speed, and step length. Additionally, significantly shorter TUG times were observed and a higher rate of discontinuation of orthopedic supplies in the study group. However, the therapy method did not have a significant effect on the average step cycle, coefficient of variability or time on each foot. These parameters showed comparable improvement in both groups. Conclusions: Treadmill training with visual biofeedback has a positive effect on certain gait parameters. The greatest benefits from this type of training can be gained by patients with deficits in stability and mobility in space.
