Continual use of augmented low-Dye taping increases arch height in standing but does not influence neuromotor control of gait

This study investigated the effect of continual use of augmented low-Dye (ALD) taping on neuromotor control of the lower limb during gait, as well as foot posture and mobility. Twenty-eight females were randomly allocated to wear ALD tape continuously or a no-tape control for a mean 12±2 days. Electromyographic activity from 12 lower limb muscles, three-dimensional motion at the ankle, knee, hip and pelvis (i.e., measures of neuromotor control) and foot posture and mobility was measured before and after the tape or control interventions. For the tape group, arch height ratio (=arch height/distance from heel to first metatarsophalangeal joint line) was greater by 0.006 (95% confidence interval: 0.0002–0.01, p=0.04) following the intervention period, whereas no change was observed for the control group (−0.003 (−0.01–0.004), p=0.36). The difference between groups (0.009 (0.0004–0.02), p=0.04) equated to a 0.16cm increase in arch height for the tape group following continual use of ALD tape. There was no change in neuromotor control of gait following continual use of ALD taping (p>0.05). Continual use of ALD tape for approximately 12 days produced a small change in foot posture, but no alteration in neuromotor control. Previous literature suggests that this increase in arch height is likely to be clinically relevant and may be one factor that contributes to the known efficiency of ALD tape in the treatment of lower extremity pain and injury.
