Functional ankle instability, Drop landing, Groundreaction force.
Objective: Objective of the study was to examine effect
of taping on peak ground reaction forces (GRFs) and time
to peak GRFs in persons with functional ankle instability
(FAI) during post impact single drop landing.
Methods: Ten persons with FAI participated in the study.
They were 3 males and 7 females collegiate athletes
playing volleyball (n = 4) and basketball (n = 6).
Averaged age, weight, and height were 20.6 ± 2.67 years,
61.80 ± 11.99 kg, and 165.50 ± 10.54 cm. Participants
were tested single drop landing with the instability foot on
forceplate. Three taping conditions were assessed; no
tape, Kinesio tape, and non elastic tape.
Results: Minimal reductions of GRFs were demonstrated
in taping conditions but no statistical difference (p > 0.05)
when compared to no taping. Minimal increases in all
times to peak GRFs (except for the anterior force) were
found in the Kinesio tape condition. Only the time to peak
vertical GRF demonstrated significant difference (p =
0.039) among three taping conditions.
Conclusion: Minimal beneficial effect of the Kinesio
taping was demonstrated in terms of decreased the peak
GRFs and prolonged time to peak GRFs during post
impact of landing.
