6,000 m 고도에 해당하는 급성·평압 저산소 조건에서 키네시오 테이핑 적용이 고유수용성 감각기능에 미치는 영향

Purpose: It is known that there is impairment in the responses of ther opprioceptive sense function at high altitudes. However, the effect of Kinesio taping (KT) on the response of joint position proprioception to acute normobaric hypoxia remains unclear. The purpose of this study is to evaluate the effect of KT on proprioceptive sense function in a normobaric hypoxic condition corresponding to an altitude of 6,000 m. Method: In a single-blind, balanced crossover study, 18 healthy voluneters (22.7 ± 1.8 years) were randomly allocated to receive either Kinesio taping + hypoxia (KH), hypoxia (HP), or control (CT) with a 1-week interval. For the assessment of proprioceptive sense function,a ctive joint position sense (AJPS) and passive joint position sense (PJPS) were measured at a knee angle of 5°5 of flexion from the maximal passive exte-n sion. KT was applied to different regions of the knee extension muscle group. The acute normobaric hypoxic condition was maintained for 40 minutes using a low oxygen gams ixture. All data were analyzed using twoway ANOVA with repeated measures. Results: The absolute angular error of AJPS in KH and HP was significantly greater than that in CT at posttest (8.0 ± 4.3 and 8.8 ± 6.0, respectively, vs. 2.5 ± 1.3, P<0.01). The absolute angular error of PJPS in KH and HP was significantly greater than that in CT at post-test (7.1 ± 5.5 and 6.8 ± 2.2, respectively, vs. 2.2 ± 1.6, P<0.01). However, the absolute angular error was not significantly different between KH and HP. Conclusion: These results suggest that acute hypoxia impairs the proprioceptive sense function of the knee, and hypoxia-induced damage to proprioceptive sense function is not affected by Kinesio taping.
