بررسي اثر دستكش‌هاي آتش‌نشاني مختلف مورد استفاده در عمليات اطفاي حريق بر چابكي دست و انگشتان

Investigation of the Effect of Different Firefighting Gloves on the Dexterity of Hands and Fingers

سابقه و هدف: يكي از شايع‌ترين مشكلات آتش‌نشانان، تنزل عملكرد دست حين استفاده از دستكش‌هاي حفاظتي مي‌باشد. با توجه به تنوع دستكش آتش‌نشاني در ايران، پژوهش حاضر با هدف بررسي و مقايسه اثر اين دستكش‌ها بر چابكي دست صورت پذيرفت. مواد و روش‌‌ها: براي انجام اين مطالعه دو مدل از مرسوم‌ترين دستكش‌هاي آتش‌نشاني جهت بررسي انتخاب شدند. در اين پژوهش چابكي با استفاده از چهار آزمون استاندارد Bennett، مينه‌سوتا، پگ‌بورد و پگ‌بورد اصلاح‌شده براي هر جفت دستكش در ارتباط با 40 دانشجوي مرد ارزيابي گرديد. همچنين از آزمون‌هاي ويلكاكسون و ضريب همبستگي Spearman و Friedman به‌منظور مقايسه چابكي و فاكتورهاي اثرگذار بر آن استفاده گرديد. يافته‌ها: نتايج نشان دادند كه نوع دستكش اثر معناداري بر چابكي دست دارد (0/001

Background and Objective: One of the most common problems of firefighters is performance degradation while using protective gloves. Regarding the existence of various types of firefighting gloves in Iran, this study aimed to investigate and compare the effect of these gloves on hand dexterity. Materials and Methods: Two types of the most widely used firefighting gloves were selected for the purpose of this study. The dexterity was evaluated using four standard tests, including Bennett, Minnesota, Pegboard, and modified Pegboard, for each pair of gloves on 40 male students. The Spearman's correlation coefficient, Wilcoxon test, and Friedman test were used to compare dexterity and its effective factors. Results: Based on the obtained results, the type of gloves had a significant effect on hand dexterity (P<0.001). The findings showed that the modified Pegboard test had high sensitivity in measuring finger dexterity. However, the Pegboard test due to its low sensitivity and severe reduction in scores was not suitable for measuring dexterity. The Bennett and Minnesota tests due to their similar trends can be used to measure hand dexterity. In addition, since Minnesota test was less tiresome and solved some problems, it can be used instead of the Bennett test. Conclusion: Various firefighting gloves available in the market have different effects on the dexterity of the hands and fingers. Therefore, this should be considered by firefighting organizations. It is recommended to evaluate dexterity while using firefighting gloves with the help of the modified Pegboard and Minnesota tests.
