Abstract
Context: Using accessible, and cost efficient technology, clinicians may be able to correct faulty running mechanics. Our purpose was to evaluate how video technology compares to verbal feedback when using feedback as a clinical tool. Methods: We performed a 2x3 mixed model randomized control trial with a study population of 9 volunteer recreational runners between the ages of 21 and 37. Participants received either verbal and visual feedback using the “Coach’s Eye” application, only verbal feedback, or no feedback. Main outcome measures consisted of changes from baseline to post test, with regards to knee flexion, hip extension, vertical oscillation, midfoot strike, forward lean, step rate and rate of perceived exertion.
Results: A one way repeated measures ANOVA revealed participants who received both verbal and visual feedback demonstrated significant changes from pre (mean=8.33±1.5) to post (mean=5.6±1.1; F1,2=64, P=0.015, n2= .96) in vertical oscillation and midfoot strike pre (mean=89.6±6.35) to post (mean=103.3±7.76; F1,2=105.062, P=0.009, n2=.994). Participants in the verbal feedback only group demonstrated significant changes in forward lean from pre (mean=10.3±.577) to post (7±1.73; F1,2=25, P=.038, n2=.719). There were no significant changes in the control group (P>.05). Conclusions: The results of this study demonstrate that verbal and visual feedback is an effective means to correct select faulty running biomechanics in recreational runners.
