摘要

目的：本研究目的是運用最新材料科技的薄形高彈性足弓墊，搭配於足弓墊的後足及中足外側貼上楔型墊，應用於膝關節不適的病人之效果。方法：本研究以WOMAC量表評估受測者使用新型二段式外側楔型足弓墊後的效果。其中實驗組的24名受測者依WOMAC之分數高低，分為高分組（12名）、低分組（12名），另外9名為對照組。本研究將於實驗組介入新型二段式外側楔型足弓墊2個月。2個月後再做第二次的WOMAC量表評估介入足弓墊後的改善情況。結果：由結果可知，介入新型二段式外側楔型足弓墊後，實驗組中，75%受測者的WOMAC量表有改善（P＜0.05）。且實驗組中，WOMAC高分組的改善效果比低分組的好（100%vs50%）（P＜0.05）。膝關節不適者介入新型二段式外側楔型足弓墊兩個月後，可能有效改善其膝關節之疼痛、僵硬和功能的情況。結論：結論是此種新型二段式外側楔型足弓墊對膝關節不適的病人可能有改善之效果，進一步應用生物力學的研究來佐證有其必要性。

Objectives: Knee discomfort is one of the most common diseases among adults, and is associated with pain, joint stiffness and influences activities of daily living. The purpose of this study was to assess the effect of wearing a new type of two-segment lateral wedge shoe insole on knee discomfort. Methods: The study recruited 24 knee discomfort subjects as intervention group and 9 healthy subjects as control group. The intervention group was further divided into high score group (N=12) and low score group (N=12) according to subjects' initial WOMAC score. ,The two-segment lateral wedge shoe insole was custom-made for all subjects in the intervention group, and wore for 2 months. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was evaluated at initial and after 2 months. Results: The results showed 70% improvement of WOMAC score in the intervention group (P＜0.05), and the high score group gained more improvement than low score group (100% vs 50%)(P＜ 0.05). Conclusion: We concluded that this newly designed insole may improve knee discomfort of the patients. Further study is recommended to evaluate the biomechanical effects of the new design.
