Evaluate the acute effect of low-Dye, placebo and no tape on motor behaviour in individuals with plantar fasciitis (PF).Prospective, experimental.Motion analysis laboratory.Ten participants with PF and ten matched controls.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.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.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.
