12週下肢肌力訓練對扁平足與正常足型高齡者跌倒風險的影響之初步探討

The Effect of Twelve-week Lower Extremities Strengthening Program for Normal Foot and Flat Foot Elders' Falling Risk - Preliminary Investigation

目的：本研究在探討12週下肢肌力訓練對功能性扁平足與正常足型高齡者之跌倒相關因子的影響。研究方式：受試者為22位男、女65歲以上的人，並將受試者分為正常足型組（13位）與扁平足型組（9位）。在介入下肢肌力訓練之前、後進行跌倒危險因子檢測，以獨立樣本t-test比較兩組跌倒危險因子項目之差異。實驗結果：正常足型組在椅子站立、5公尺步行及右足底面積達到統計上顯著差異（p＜.05），扁平足組在開眼單足立和右足底面積達統計上顯著差異。結論：12週下肢肌力訓練對於正常足型的長者在生活上的步行穩定與靜態平衡比較有幫助，對扁平足的長者生活上的靜態平衡比較有幫助，並且可增加這兩類足型的長者站立時的著地面積，減少跌倒的風險。

Purpose: The investigation is to research the effect of 12-week lower extremities strengthening program for normal foot and functional flat foot elder's falling risk. Method: 22 female and male subjects whose age are above 65 years old. They are assigned into normal foot group (NFG) or flat foot group (FFG). Before and after strengthening, we analyze their falling risky factors by independent t-test. Result: In NFG, 30-s chair stand, five-meter walking velocity and right foot base area are statistically significant. (p＜.05) In FFG, single-foot standing test with eyes-opened and right foot base area are statistically significant. Conclusion: 12-week lower extremities strengthening program is more effective for normal foot elders' walking stability and static balance and flat foot elders' static balance. It also increases their standing area and decreases falling risk.
