摘要
背景:正常人握捏力数据为手功能障碍的评估及治疗提供重要参考依据,但到目前为止国内仍缺乏一套大样本的握捏力常模数据。目的:旨在分析健康大学生的握力、捏力正常值,并且探讨握捏力与计量资料之间相互关系。方法:募集111名福建中医药大学二年级学生,男65名,女46名。在同一握力体位下,应用E-link电子握捏力计分别测试学生握力、侧捏、三指捏、指尖捏捏力。同时测量身高、体质量、前臂长度、前臂围度、手宽、手长、手掌厚,分析相互关系。结果与结论:男女利手握捏力均高于非利手(差异10%以内),男性握捏力值均大于女性。男女侧捏与三指捏力无显著差异,均明显高于指尖捏力。握捏力值与国外同龄数据相差较大,尤其是男性。握力体质量比男性74%,女性58%;3种捏握比均低于传统认定正常值30%:男性(14.8%～21.6%)、女性(16.9%～24.3%)。左右手握捏力呈高度相关(r=0.680～0.872,P<0.01),男女性握力及3种捏力之间呈中度相关(r=0.390～0.720,P<0.01),指尖捏力与人体计量资料不相关,年龄、前臂长与握捏力无关。身高仅与男性握力相关,手掌厚与男性握捏力(除指尖捏力)相关,与女性无关。与握捏力相关的主要计量资料有体质量、前臂围度、手宽、手长,尤其手宽度是预测男女性握力重要指标。
BACKGROUND：The norms of hand grip and pinch strength can provide an important reference for the assessment and treatment on hand dysfunction,a large sample normative data of hand grip and pinch strength is still not available in China.OBJECTIVE：To analyze the grip and pinch strengths of university students in order to establish the relationship among grip strength,pinch strength and anthropometric factors.METHODS：In total 111 sophomores（65 males and 46 females） from the Fujian Traditional Chinese Medicine University were recruited.E-link electric dynamometer was used to measure grip strength and E-link electric pinch gauge to measure key,palmar,and tip pinch with a standardized position.All anthropometric factors such as age,gender,height,weight,forearm length,forearm circumference,hand width,hand length,as well as hand thickness were recorded.The relative correlations were analyzed.RESULTS AND CONCLUSION：The grip and all pinch strength of dominant hands for both genders were greater than the nondominant hands（within 10% difference）.The grip and all pinch strength of the males were higher than those of the females.The grip and all pinch strength of Chinese students for both genders were lower than American students＇,especially for the males.Grip-weight ratio was 74% in the males and 58% in the females.Three pinch-grip ratios were lower than 30% mentioned in the textbooks：the males（14.8-21.6%）,the females（16.9-24.3%）.A strong correlation of the mean in grip and pinch strength was found between the right and the left hand（r=0.680-0.872,P 0.001）.A moderate correlation was showed between grip and pinch strength of three types（r=0.390-0.720,P 0.01）.The tip pinch strength had no correlation with any anthropometric factors.No correlation has been found among the grip,key pinch,palmar pinch strength,age,and forearm length.Height had correlation with grip strength in male students.The thickness of thenar eminence was correlated with grip,key pinch,palmar pinch in male students.The grip and pinch strength were moderately correlated with major anthropometric factors such as weight,forearm circumference,hand width,hand length.Hand width was proved to be a major predictor of grip strength.
