Maximum reach envelopes for the 5th, 50th and 95th percentile reach lengths of males and females in seated and standing work positions were determined. The use of a computerized potentiometric measurement system permitted functional reach measurement in 15 min for each subject. The measurement system captured reach endpoints in a dynamic mode while the subjects were describing their maximum reach envelopes. An unbiased estimate of the true reach distances was made through a systematic computerized data averaging process. The maximum reach envelope for the standing position was significantly (p<0.05) larger than the corresponding measure in the seated position for both the males and females. The average reach length of the female was 13.5% smaller than that for the corresponding male. Potential applications of this research include designs of industrial workstations, equipment, tools and products.
确定了男性和女性在坐姿和站姿工作位置时第5百分位、第50百分位和第95百分位伸展长度的最大伸展范围。使用计算机化电位测量系统，每位受试者可在15分钟内完成功能性伸展测量。测量系统在受试者描述其最大伸展范围时，以动态模式捕捉伸展端点。通过系统的计算机化数据平均过程，对真实伸展距离进行了无偏估计。对于男性和女性，站立位置的最大伸展范围均显著大于（p<0.05）相应的坐姿测量值。女性的平均伸展长度比相应男性小13.5%。该研究的潜在应用包括工业工作站、设备、工具和产品的设计。
