To examine the effect of KT on gastrocnemius surface electromyography (SEMG) activity and ankle range of motion during walking in healthy subjects.
Randomized controlled trial, with concealed allocation and assessor blinding.
University Biomechanics Laboratory.
Thirty six healthy physiotherapy students were randomized to KT or control group.
At baseline and immediately after 72 h with the tape in situ: amplitude of LG SEMG activity during the stance phase, duration of the LG activity, onset and offset times of LG activity, ankle plantar- and dorsiflexion peaks, and the cadence of gait.
ANOVA revealed a significant time × intervention interaction effect across two variables: duration of LG activation, F(1, 33) = 4.71, p = .037, η = .015; and onset F(1, 33) = 7.92, p = .008, η = .037. KT group showed significantly shorter duration of the LG activity as compared with control, and similar results were observed when comparing the onset of LG activation. No statistically significant differences between both groups were noted in the rest of the outcomes.
KT does significantly shorten the duration of the LG activity during gait when applied 72 h in healthy adults. However, this result was not accompanied by a significant reduction in the amplitude of LG SEMG activity.
研究肌内效贴(KT)对健康受试者行走过程中腓肠肌表面肌电图(SEMG)活动及踝关节活动范围的影响。
随机对照试验,采用隐蔽分组和评估者盲法。
大学的生物力学实验室。
36名健康的物理治疗专业学生被随机分为KT组或对照组。
在基线时以及贴扎72小时后立即测量:站立期外侧腓肠肌SEMG活动的幅度、外侧腓肠肌活动的持续时间、外侧腓肠肌活动的起始和结束时间、踝关节跖屈和背屈峰值以及步频。
方差分析显示,在两个变量上存在显著的时间×干预交互效应:外侧腓肠肌激活的持续时间,F(1, 33) = 4.71,p = .037,η = .015;以及起始时间,F(1, 33) = 7.92,p = .008,η = .037。与对照组相比,KT组外侧腓肠肌活动的持续时间显著缩短,在比较外侧腓肠肌激活的起始时间时也观察到了类似结果。在其余观察指标上,两组之间未发现统计学上的显著差异。
在健康成年人中应用72小时后,KT确实能显著缩短步态中外侧腓肠肌活动的持续时间。然而,这一结果并未伴随着外侧腓肠肌SEMG活动幅度的显著降低。
