The effectiveness of real-time haptic feedback gait retraining for reducing resultant tibial acceleration with runners

Abstract

ObjectivesTo examine the effectiveness of real-time haptic feedback gait retraining for reducing resultant tibial acceleration (TA-R) with runners, the retention of changes over four weeks, and the transfer of learning to overground running. DesignCase control. SettingBiomechanical laboratory treadmill, and track-based overground, running. Participants18 experienced uninjured high tibial acceleration runners. Main outcome measuresTA-R measured while treadmill and overground running assessed at pre-, post- and 4-weeks post-intervention. ResultsAcross the group, a 50% reduction in TA-R was measured post-intervention (ES: 0.9, z = −18.2, p < .001), and 41% reduction at 4-weeks (ES: 0.8, z = −12.9, p < .001) with treadmill running. A 28% reduction (ES: 0.7, z = −13.2, p < .001), and a 17% reduction in TA-R were measured at these same time points when runners ran overground (ES: 0.7, z = −11.2, p < .001). All but two runners responded positively to the intervention at the post-intervention assessment. Eleven runners were categorised as positive responders to the intervention at the 4-week post-intervention. ConclusionsHaptic feedback based on TA-R appears to be as effective, but less invasive and expensive, compared to other more established modalities, such as visual feedback. This new approach to movement retraining has the potential to revolutionise the way runners engage in gait retraining.
