中文摘要 | 本研究的目的是利用測力板系統評估大台北地區不同年齡層之健康成 年人的動態平衡測驗的表現,並比較年齡對動態平衡能力的影響。利用測力板系 統(電腦平衡測定儀Neurocom International Inc.)收集51位健康正常人動態平衡測驗 的資料,使其年齡層分成三組:青年組(20-35歲)有17名,中年組(40-55歲)有15名, 老年組(60-78歲)有19名。動態平衡測驗包含前後方向與左右方向的規律重量轉移 測驗以及多方向重心轉移測驗。結果顯示三組於前後方向規律重量轉移測驗的平 均位移量有賴著差別(P<.05),其平均位移量以青年組最大,中年組次之,老年組 最小。於左右方向規律重量轉移測驗則無顯著年齡效應。於多方向重心轉移測驗 方面,老年組與青年組於向前、後、左後及左等方向的平均位移時間有有顯著差 異(p<.05);此外,向右、後及左後等方向的平均位移量亦有顯著差異(p<.05)。中年 組於多方向重心轉移測驗中的表現與其它兩組無顯著差別。本研究結果建議老年 組前後方向的重心轉移能力較年青人差可能是來自平衡控制的改變。本報告可以 作為利用電腦平衡測定儀評估與訓練病人時之參考。(中華物療誌 1995;20(1):81-90) |
英文摘要 | The purpose of this study was to comparethe dynamic balance of healthy adults in threeage groups. A total of 51 subjects (20 - 78 yearsold) was divided into a young-age (n=17, 20 -35 years old), a middle-age (n=15, 40-55 y/o),and an old-age (n=19, 60-78 years old) group.All subjects were tested on a dynamic posturegraphic system (Balance Master system, NeuroCom Int. Inc.) for their ability for : (1) rhythmicweight shifting to left and right, (2) rhythmicweight shifting to forward and backward, and(3) weight shifting to 75 of the Limit of Stability (LOS). The postural sway path, amplitude,and time to targets were measured by aforceplate and analyzed by one-way ANOVAs.The results showed that the amplitude of postural sway differed significantly between agegroups during the rhythmic weight shifting inthe forward and backward directions (p<.05).The young-age group swayed the largest, andthe old-age group the least. No significant difference in the amplitude of postural sway between age groups in the left and right direction during rhythmic weight shifting test was found. In the test of weight shift to 75 of LOS, the time to target was significantly different be tween the young- and old-age groups in 4 out of8 tested directions. The 4 significantly differentdirections were forward, backward, left back ward, and left (p<.05). The sway path was sig nificantly different between the young- and old- age groups for 3 (right, backward, left) out of the 8 tested directions. No differences were.found between the middle-age group with the old- or the young-age groups. During the experi ment, the researchers observed more older adults to select postural strategies different from theyounger adults. Thus it is suspected that thedeclination in the dynamic balance ability in theold-age group may be due to changes in the selection of postural strategy. It is recommendedthat age effect be considered and postural strategy recorded when dynamic balance ability is tobe evaluated in healthy adults. (JPTA ROC1995;20(1):81-90) |
