Multidimensional impact of low-Dye taping on low-load hopping in individuals with and without plantar fasciitis.

OBJECTIVES

Evaluate the acute effect of low-Dye, placebo and no tape on motor behaviour in individuals with plantar fasciitis (PF).

DESIGN

Prospective, experimental.

SETTING

Motion analysis laboratory.

PARTICIPANTS

Ten participants with PF and ten matched controls.

MAIN OUTCOME MEASURES: Hopping behaviour (lower-limb stiffness and ankle angle at peak loading) were evaluated during low-load sleigh hopping, during three taping conditions. Stiffness and ankle angle were determined using three-dimensional motion analysis. Pain during submaximal loading was assessed with a numeric pain rating scale.

RESULTS

The lower-limb stiffness response to therapeutic taping was modulated by the presence of PF (interaction, F = 4.48, p = 0.018). Matched controls demonstrated a significant increase in stiffness post application of low-Dye taping (p = 0.001), stiffness was unchanged in the PF group. In the PF group, low-Dye taping decreased hopping pain in comparison to placebo (p = 0.037) and no-tape (p = 0.024). There was no difference in ankle angle at peak loading between the groups or across taping conditions.

CONCLUSIONS

Low-Dye taping reduces nociceptive inputs more than placebo in the presence of PF pain. Low-Dye tape alters stiffness in the control group but not the PF group. The motor behavioural outputs such as stiffness, during low-load hopping is modulated by both pathology and therapeutic taping.
