Does Dynamic Tape change the walking biomechanics of women with greater trochanteric pain syndrome? A blinded randomised controlled crossover trial.

There is considerable debate among clinicians as to whether sports tape can provide mechanical support and pain relief. People with greater trochanteric pain syndrome (GTPS) have increased adduction moment, adduction angle and pelvic obliquity, likely contributing to the continuation of the pathology. We aimed to see if Dynamic Tape Fifty women with GTPS participated in a three-dimensional gait analysis. Each participant performed three walking trials: baseline, and two subsequent trials, with active and sham applications of Dynamic Tape. The order of active and sham taping was randomised. Differences in kinetic and kinematic data were analysed using mixed model linear regressions for each condition. Pain scores were obtained before and immediately after walking trials. Hip adduction moment was reduced at first peak by both active (p < 0.001) and sham tape (p = 0.028), with no between group difference; at second peak by the active taping (p < 0.001), with a between-group difference (p < 0.001). Adduction angle was reduced at first peak by both active (p < 0.001) and sham taping (p = 0.026), with the active taping producing a larger effect (p = 0.004); at mid-stance by active taping (p = 0.003), with a between-group difference (p = 0.002); there was no reduction at second peak. Internal rotation was reduced at the first (p < 0.001) and second peaks (p < 0.001), and mid-stance by the active taping alone (p < 0.001). Pelvic obliquity was reduced at the first peak (p = 0.019), mid-stance (p < 0.001) and second peak (p < 0.001) by the active tape, with a between-group difference at mid-stance (p = 0.03). Both the active and sham taping resulted in a clinically meaningful pain reduction. Dynamic Tape produced a mechanical effect and a meaningful reduction in pain in women with GTPS. The extent that placebo or somatosensory input may have had on these results is not clear. ACTRN12617001611314.
