摘要

足跟墊具有特殊的組織結構與黏彈性質，故能有減少和吸收足部與地面撞擊所產生之衝量。一般咸信其避震功能受損是造成足跟疼痛症候群的原因之一。運動員常使用貼布來提供足跟墊外在的支撐，對足跟墊產生限制效應，將足跟周圍的脂肪組織往足底擠壓，以增加其減震和吸震能力，進而預防或治療足跟疼痛症候群。然而貼紮對於足跟墊的限制效應是否真能改變其形態及機械性質，進而影響其避震功能，迄今尚乏實證型研究。本研究計畫藉由超音波影像儀及荷重轉換器來檢測足跟疼痛者或一般健康成人在站立負載－卸載的過程中的足跟墊影像及負載之變化，其目的為評估足跟疼痛者與一般健康成人兩組的足跟墊在貼紮前後之厚度、受壓性指數和能量耗散率，以瞭解貼紮之限制效應對足跟墊機械性質的影響。

本研究屬於前瞻性的研究，為一擬實驗設計，共收取10 名足跟疼痛者與 10名年齡與身體質量指數與之配對之健康受測者的資料。每一位受測者站立在一測試平台上，重心先置於非測試足，實驗時以最快的速度將重心由非測試足移至待側足，再迅速移回非測試足，對待測足之足跟墊產生一個負載－卸載過程。以超音波影像儀擷取此負載－卸載過程中足跟墊應變的變化，同時並以荷重轉換器擷取應力的變化。測試狀況則為貼紮與否（無貼紮 vs. 貼紮）及雙腳（足跟疼痛者：疼痛足 vs. 非疼痛足；控制組：慣用足 vs. 非慣用足）等交叉成四種狀況。測試順序採區集隨機方式，以降低動作學習的效果。將所擷取的資料用來計算足跟墊厚度、受壓性指數、和能量耗散率，以比較受測者足跟墊的機械性質。統計方法採用2

The unique architecture and viscoelastic properties of the heel pad provide reduction and absorption of the impact forces acting on the heel, such as heel strike. Loss of shock attenuation capacity has been documented as one of the predisposing factors of plantar heel pain. Providing a confinement effect to the heel pad by constraining its lateral and medial margins, the heel pad taping is a common method to reduce or prevent plantar heel pain, especially for the athletes. There is, however, no scientific evidence to explore the effects of taping on the shock attenuation capacity of the heel pad. The purpose of this study was to determine the confinement effect of taping on the shock attenuation capacity of the heel pad in both patients with plantar heel pain and healthy adults. The shock attenuation capacity of the heel pad was characterized by its thickness, compression index (CI), and energy dissipation rate (EDR).

The present study is a prospective quasi-experiment design. Ten patients with unilateral plantar heel pain and 10 age- and BMI-matched controls were tested using a novel technique that ultrasonography incorporated with the load cell to record heel pad thickness and the synchronized impact force. The task performed by the participants was a dynamic loading-unloading test. Each participant was asked to stand on a testing platform and shift the whole body weight from one foot to the other and then back to the original one as fast as possible for creating a dynamic loading-unloading process to the heel pad. There were 4 testing conditions, including a combination of 2 taping (taped vs. untapped) and both feet (affected foot vs. intact foot for the patient group and dominant vs. non-dominant foot for the control group) conditions. The testing order was selected according to a randomized block design for minimizing the learning effect. The 2
