摘要

本研究目的為探討年齡與性別對足底壓力中心前進路徑(center of foot pressure progression/COPP)之影響。90位健康的受試者(老年人、學齡兒童、學齡前孩童各30位)參與實驗。在行走速度為自選速度下，始用足底壓力量測系統(RSscan® system)收集足底壓力中心座標路徑、移動速度與路徑之偏移角度(progression angle/PA)等參數。
實驗結果顯示，一個步伐時間之足底壓力中心轉移路徑於開始接觸期(ICP)、足前接觸期(FFCP)、足底平放期(FFP) 與足前推進期(FFPOP)四個時期之時間比例，老年人為5.6%、4.9%、57.4%與32.1%；學齡兒童為9.4%、7.1%、43.2%與40.3%；學齡前兒童為11.7%、14%、33.9%與40.4%。足底壓力中心前進偏移角度，老年人為-4.9度(SD=2.6)；學齡兒童為-2.4度(SD=2.4)；學齡前兒童為-1.3度(SD=2.3)。平均足底壓力中心移動速度，老年人為26.0公分/秒(SD=3.9)；學齡兒童為28.8公分/秒(SD=3.4)；學齡前兒童為24.6公分/秒(SD=3.3)。
性別會顯著影響足底壓力中心轉移時間比例於FFCP(p < 0.05)；年齡顯著影響足底壓力中心前進路徑於時間比例、壓力中心移動速度與壓力中心偏移角度(p < 0.05)。

This study aims to elucidate the characteristics of center of pressure progression(COPP) for elderly adults, children and preschool children. Ninety subjects were recruited to participate in this study (Thirty elderly adults, thirty children, thirty preschool children). All subjects were asked to barefoot walk with self-selected walking speeds. A foot pressure measurement system (RSscan ® system) was used to collect data of the center of pressure progression (COPP), velocity of center of pressure and progression angle (PA) of the COP pathway.
The results of this study indicate that the percentage of time (% time) of the stance phase in initial contact phase (ICP), forefoot contact phase (FFCP), foot flat phase (FFP) and forefoot push off phase (FFPOP) were about 5.6%, 4.9%, 57.4% and 32.1% for elderly adults. 9.4%, 7.1%, 43.2% and 40.3% for children. 11.7%, 14%, 33.9% and 40.4% for preschool children.
The average progression angle (PA) of the COP pathway was -4.9 degree (SD=2.6) for elderly adults. -2.4 degree (SD=2.4) for children. -1.3 degree (SD=2.3) for preschool children.The average velocity of the COP was 26.0 cm/s (SD=3.9) for elderly adults. 28.8 cm/s (SD=3.4) for children. 24.6 cm/s (SD=3.3) for preschool children.
Gender significantly influenced the % time during the phases of FFCP (p<0.05). Moreover, age significantly influenced the time % of COPP, velocity of center of pressure and progression angle (PA) of the COP pathway.
