中文摘要 | 許多職業需長時間站立,因此造成很多身體疼痛與不適工作抱怨。本研究探討不同地面/鞋子在久站下對足底主觀不適評比與小腿圍度之影響,10名健康男性於4種不同足底/地面之組合進行4小時站姿電腦作業,組合包括分別是(1)赤腳/硬表面;(2)赤腳/抗疲勞地墊;(3)氣墊運動鞋/硬表面;(4)氣墊運動鞋/抗疲勞地墊,並在實驗前與實驗中每小時結束時量測小腿圍度與足底主觀不適評比結果顯示足底主觀不適評比顯著受不同足底/地面介面影響,於赤腳/硬表面條件下最不舒適,而於氣墊運動鞋/抗疲勞地墊條件下不舒適程度最小,較硬的足底/地面介面增加不適的程度,足底主觀不適評比亦顯著隨站立時間長度而增加。小腿圍度顯著受不同足底/地面介面與站立時間影響,但卻於氣墊運動鞋/硬表面條件下有較大的圍度變化,於氣墊運動鞋/抗疲勞地墊面條件下有較小的圍度變化。研究中多數客觀量測因子並無直接與足底主觀不適評比呼應,因此除了血液循環外,足底壓力可能為照成下肢與足部不適主要原因。 |
英文摘要 | In many occupations, workers are standing for a prolonged period to work, resulting in complains of discomfort and pain. This study explores the influence of foot/floor interface on comfort and shank circumference. Ten healthy male volunteers performed 4 h of computer works while standing on four different foot/floor combinations, consisting of 2 foot (air-cushioned sport shoes, barefoot) and 2 floor (soft mat, and hard surface (force-plate)) conditions. The parameters measured pre-experiment and during the 4h work were perceived discomfort ratings in feet and shank circumference. Experimental results show that the foot/floor interface significantly affected discomfort rating of feet. There was subjectively more discomfort standing on the barefoot/hard surface combination, and there was less discomfort on the sport-shoe/mat combination. Hard foot/floor interface increased the discomfort ratings. The discomfort ratings also significantly increased with standing duration. An analysis of variance found that the shank circumference was influenced by standing duration and foot/floor interface. Unexpectedly, we found the highest increase of shank circumference in the sport shoe/hard surface combination, and lowest in the sport shoe/mat combination. In this study, objective measures did not reflect the subjective responses of discomfort rating. Therefore, in addition to circulatory factors, foot contact pressure may play an important role in the explanation of discomfort in legs and feet during prolonged standing. |
