Each plantar pressure measurement system has a different accuracy and reliability, which is required to establish a range of normal values and determine the reliability.
To determine normal pressures with the Gaitview(®) system and assess its reliability.
Single-group repeated measures.
Dynamic barefoot plantar pressure data were obtained in 30 healthy young participants. In each session, three trials were recorded by one examiner for each foot using the two-step gait initiation method, which was repeated by another examiner the same day. One week later, all of the procedures were repeated. Time-integral mean pressures were measured for each of eight anatomical foot regions. The foot contact time (CT) and the time-integral mean angle of the center of pressure (COP) were also measured.
The greatest time-integral mean pressures were seen under the medial and lateral heel. The mean CT was 0.9 sec for both feet, and the time-integral mean angle of the COP was 9.3° for the right foot and 6.6° for the left. The intraclass correlation coefficients (ICCs) ranged from 0.69 to 0.97, and the coefficient of variation (CoV) from 9.9 to 59.97% for all parameters.
These findings indicate that the Gaitview(®) system demonstrates good to moderate reliability.
The Gaitview(®) AFA-50 system (alFOOTs, Seoul, Republic of Korea) has been used by clinicians in Korea, but has not been investigated in an independent study. Therefore, this study established a range of normal values and determined the reliability of the Gaitview(®) AFA-50 system.
每个足底压力测量系统都有不同的准确性和可靠性，这对于建立正常数值范围和确定可靠性是必需的。
使用Gaitview（®）系统确定正常压力并评估其可靠性。
单组重复测量。
获取30名健康年轻参与者的动态赤足足底压力数据。在每次测试中，一名检查者使用两步步态起始方法为每只脚记录三次试验，同一天由另一名检查者重复进行。一周后，重复所有程序。测量八个足部解剖区域各自的时间积分平均压力。还测量了足部接触时间（CT）和压力中心（COP）的时间积分平均角度。
在内侧和外侧足跟下方观察到最大的时间积分平均压力。双脚的平均CT均为0.9秒，COP的时间积分平均角度右脚为9.3°，左脚为6.6°。所有参数的组内相关系数（ICC）范围为0.69至0.97，变异系数（CoV）为9.9至59.97%。
这些结果表明Gaitview（®）系统显示出良好至中等的可靠性。
Gaitview（®）AFA - 50系统（alFOOTs，韩国首尔）已被韩国临床医生使用，但尚未在独立研究中进行调查。因此，本研究建立了正常数值范围并确定了Gaitview（®）AFA - 50系统的可靠性。
