目的:肌內效貼紮其中一個效果的療效是藉由不同貼紮方式可改善肌肉功能及增進柔軟度,但是過去未曾證實該機轉的效果。因此本研究之目的是比較腓腸肌促進肌肉收縮方式的肌內效貼紮或抑制肌肉收縮方式肌內效貼紮對正常健康運動員踝關節背屈關節活動度與蹠屈等長收縮肌力的影響。方法:共15 位健康運動員接受測試,平均年齡為19.6 ± 2.0 歲,以關節量角器及手持式徒手肌力測試器,分別進行肌內效貼紮前後,踝關節背屈活動度及蹠屈等長肌力評估。貼紮方式分為促進肌肉收縮方式之貼紮及抑制肌肉收縮方式之貼紮。以無母數魏克遜符號等級考驗分析促進及抑制貼法對踝關節蹠屈等長肌力及主動背屈關節活動度的差異。結果:受試者在踝關節背屈角度測試及蹠屈等長肌力測試結果,顯示促進或抑制貼法兩者間均無顯著差異(p > .05)。結論:無明顯下肢柔軟度差異的健康運動員,在接受促進或抑制貼法前後,其踝關節背屈角度與蹠屈等長收縮肌力均無顯著變化。未來可先區別不同下肢柔軟度等級之受試者,再進行試驗,以瞭解肌內效貼紮的效果及影響。
Purpose: One of the possible mechanism of Kinesio Taping (KT) is to improve muscle function and flexibility, in which the mechanism has not been well identified in the past. This study aimed to compare the effect of facilitation and inhibition methods of KT on the Calf muscle strength and ankle range of motion (ROM) of Gastrocnemius muscle in healthy athletes. Methods: Fifteen healthy subjects (mean age: 19.6 ± 2.0 years old) performed ROM for ankle dorsiflexion and isometric muscle strength test for ankle plantarflexion with knee extension before and after KT applied using the Goniometry and MicroFet 3 hand-hold dynameters. The Kinesio taping was applied to either facilitate or inhibit muscle contraction. Data were analyzed using nonparametric Wilcoxon Signed Ranked Test in order to compare the difference between facilitating and inhibiting methods on ankle plantarflexion isometric muscle strength and active ankle dorsiflexion ROM. Results: No significantly difference was showed in ROM of ankle dorsiflexion and isometric muscle strength of ankle plantar-flexor between two taping direction of KT (p > .05). Conclusions: For general flexibility healthy subjects, no facilitation or inhibition effects were noted on the muscle strength of ankle plantar-flexor and ankle dorsiflexion angle, either along or reverse the contraction direction of muscles. The future studies would discriminate the difference of lower extremities flexibility to find out the effect of KT in muscle strength and range of motion.
