Abstract:

Objective To compare the effects of proprioceptive neuromuscular facilitation (PNF) and whole body vibration training (WBVT) on functional ankle instability (FAI).

Methods From May to July, 2021, 17 male FAI undergraduates from Beijing Sport University received PNF (n = 8) and WBVT (n = 9), for six weeks. They were assessed with Y-balance test, Pro-Kin, Kistler and Motion Analysis Raptor before and after invention, to observe Y-balance score, average trajectory error, kinematics and dynamics after jump-landing of affected limb.

Results The main effect of training was not significant for all the Y-balance score, average trajectory error, kinematics and dynamics (F < 4.090, P > 0.05). However, the interactive effect of training and time was significant for the range of motion of ankle flexion (F = 6.232, P = 0.030), and the effect size was more for PNF; it was also significant for the time arriving peak ground reaction force (left-right) after landing (F = 10.674, P = 0.008), and the time was latter for WBVT (P < 0.05).

Conclusion PNF and WBVT are similarly effective on FAI.

Key words: functional ankle instability, proprioceptive neuromuscular facilitation, whole body vibration training
