手套與零件尺寸對手部靈巧性之影響

The Effects of Gloves and Component Sizes on Hand Dexterity

手是人體各部位活動最頻繁、最靈巧的，所以手有許多機會接觸到有害物質或能量等等。手套便是設計用來提供手的保護以避免各種手部的損傷與傷害。然而手套帶來的手部靈巧性下降經常阻礙了人們戴手套的意願。本研究分析了不同尺寸零件對戴手套的手的靈巧性之影響。研究中使用了4種不同厚度的手套，包括棉織、棉紗、乳膠與橡膠。以3種尺寸的木梢基板裝配組來測量參與者的手部靈巧性。參與者包括15位男性與15位女性。手部靈巧性測量則參考美國材料試驗學會（American Society for Testing and Materials, ASTM）之標準的手套之徒手控制百分率測量法。研究結果顯示，橡膠手套之徒手控制百分率數據，其變異數與其它3種手套的異質。棉織、棉紗、乳膠手套的徒手控制百分率則受到零件尺寸與手套厚度的交互作用影響。其事後檢定顯示零件尺寸對乳膠手套的影響情形不同於其對棉織、棉紗手套的影響情形。戴乳膠手套操作木梢直徑0.5 cm之木梢基板裝配組的結果，與其操作木梢直徑1.9 cm之木梢基板裝配組的結果比較，手套之徒手控制百分率平均值顯著的提高。使用棉織、棉紗或橡膠手套操作木梢直徑0.5 cm之木梢基板裝配組的結果，與其操作木梢直徑1.9 cm或0.9 cm之木梢基板裝配組的結果比較，手套之徒手控制百分率平均值都顯著的提高。

Hands are the most frequently moving and the most dexterous segments of human body. Thus hands are frequently in high risks of contact hazardous substances, energy, etc. Gloves are designed and used to protect our hands from various impairment and hurt. However, the reduction of dexterity of gloved hands often frustrate the use of gloves. This study investigated the effects of component sizes on gloved hand dexterity. Four different thickness gloves were used, including cotton cloth gloves, knitted work gloves, latex gloves and rubber gloves. Gloved hand dexterity was tested by three sizes of peg and board assembly. Subjects included fifteen males and fifteen females. Hand dexterity was measured by percent of barehanded control according to the test method of the standard of American Society for Testing and Materials (ASTM). The results showed that the sample variance of percent of barehanded control of rubber gloves was heterogeneous from that of the other three gloves. Cotton cloth, knitted work and latex gloves were affected by the interaction of component sizes and glove thickness. The post hoc test showed that the effects of component sizes on percent of barehanded control for latex gloves were different from that for cotton cloth and knitted work gloves. Using latex gloves, the average percent of barehanded control measured by operating peg and board assembly with peg diameter 0.5 cm was significantly increased compared to operating peg and board assembly with peg diameter 1.9 cm. Using cotton cloth gloves, knitted work gloves or rubber gloves, the average percent of barehanded control measured by operating peg and board assembly with peg diameter 0.5 cm compared to operating peg and board assembly with peg diameter 1.9 cm or 0.9 cm were all significantly increased.
