Self-applicable taping for plantar pressure redistribution in individuals with neutral and flatfeet: a quasi-experimental study

<jats:p>Introduction: Flatfeet is a prevalent condition that alters foot biomechanics. The Low-Dye taping technique can modulate plantar loading, but its multi-strip procedure is technically demanding and is usually applied by a clinician. Objective: To assess the immediate effects of a self-applicable taping technique on plantar pressure distribution and footprint in adults with flat or neutral feet, under static and dynamic conditions. Methodology: In a single-session, pre–post design, twenty-seven participants (18-25 years) were assigned to a flatfoot (n=9) or neutral-feet (n=18) group using the Chippaux-Smirak Index. Each participant applied the tape to their own foot under the supervision of a trained examiner, and plantar pressures were recorded with a baropodometric platform. Results: In the flatfeet group, taping was associated with a lateral shift in rearfoot pressure under both static (p=0.0077) and dynamic (p=0.0209) conditions. In the neutral-feet group, a lateral rearfoot shift (p=0.0311) and a medial forefoot shift (p=0.0057) were observed only under static conditions. No significant changes occurred in footprint. These rearfoot effects remained significant after Benjamini-Hochberg correction for multiple comparisons. Discussion: The findings regarding the lateralization of rearfoot pressure are consistent with the literature on traditional Low-Dye taping. However, this study suggests that comparable rearfoot effects may be obtained with a simplified, self-applied technique. Conclusions: A single application of this self-applicable taping was associated with an immediate, region-specific redistribution of plantar pressure in young adults with neutral or flat feet. However, controlled studies with sham conditions, clinical endpoints, and longer follow-up are needed before clinical recommendations can be made.</jats:p>
