本研究目的為建立成年人正常行走(normal
walking)時，足底壓力中心路徑(center of pressure
progression/COPP)之模式，並討論行走速度(walking
speed) 與性別(gender)對足底壓力中心(center of
pressure progression/COPP)路徑的影響。30 位受試
者（15 位男性，15 位女性）參與實驗，所有受試
者均無下肢肌肉骨骼傷害且具正常足弓 (arch
index/ AI 範圍為0.21~0.26)。在行走速度為3、4、5
公里/小時與自選速度(self-selected walking speed)
下，採用足底壓力量測系統(RS-scan ® system)收集
足底壓力中心(center of pressure progression/COPP)
路徑與足底壓力中心前進偏移角度(PA)等資料，建
立足底壓力中心路徑模式，並討論行走速度與性別
對足底壓力中心路徑模式之影響。
結果顯示，成年人之足底壓力中心路徑於開始
接觸期(initial contact phase/ ICP) 、足前接觸期
(forefoot contact phase/ FFCP)、足底平放期(foot flat
phase/ FFP)與足前推進期(forefoot push off phase/
FFPOP) 此四個時期之時間比例，分別為站立期時
間之6.8%、4.8%、47.5%與38.9%；且足底壓力中
心前進偏移角度為28.4 度(SD=0.8)；平均足底壓力
中心速度(velocity of the COP) 為37 公分/ 秒
(SD=6.1)。行走速度會影響足底壓力中心路徑於
ICP、FFCP、FFP 與FFPOP 四個時期之時間比例與
足底壓力中心速度(velocity of COP)。整體而言，隨
著行走速度的增加，足底壓力中心路徑於足前推進
期(FFPOP)的時間比例增加。性別差異在行走速度5
公里時顯著，女性之足底壓力中心路徑於足前推進
期(FFPOP)的時間比例增加；且女性之足底壓力中
心前進偏移角度(PA)比男性小。本研究所建立之成
年人足底壓力中心路徑模式，將可提供臨床步態分
析之應用。
This study aims to build the model of center of
pressure progression (COPP) for adults. The COPP is
a trajectory of center of foot pressure. The effect of
walking speed and gender on COPP model will be
discussed and elucidated in this study.
Thirty health young adults (15 men and 15
women) were recruited to participate in this study. All
subjects did not have relevant musculoskeletal disease
and all of them have the normal arch curve (arch
index/AI range between 0.21~0.26). A nested-factorial
experimental design was applied. All subjects were
asked to walk under four different speeds
(self-selected, 3 km/hr, 4 km/hr and 5 km/hr)
separately. A foot pressure measurement system
(RS-scan ® system) was used to collect data of the
center of pressure progression (COPP), progression
angle (PA) and the velocity of the COP.
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 6.8%、4.8%、47.5% and
38.9%, respectively. The progression angle (PA) is
28.4 degree (SD=0.8) and the average velocity of the
COP is 37 cm/s (SD=6.1) for the COPP model.
Walking speed influences the % time of the stance
phase in the FFPOP. Walking with the speed of 5
km/hr, women show more % time during the FFPOP.
Moreover, women also display smaller degree of PA
than men for the COPP model.
The COPP model can be the useful information
for clinical rehabilitation in evaluation, gait training,
and footwear design.
