BACKGROUND/AIM: The JAMAR-Dynamometer and the Martin-Vigorimeter are frequently used tools in a hand surgeon's daily routine. This survey is primarily concerned with the establishment of valid conversion factors for measured values of both instruments, as well as the investigation of influence of anatomical characteristics and age and sex on maximal measured grip strength.
We registered anamnestic data and specific anatomical conditions in 339 patients, maximal grip strength was measured using all notches of both instruments.
We found moderate to very high correlation comparing all 28 settings in both instruments. The influence of the hand's anatomy on the grip strength was greater using the JAMAR-Dynamometer than it was using the Martin-Vigorimeter.
The high reproducibility allowed us to calculate multiplying factors for the conversion of measured data for all settings of both tools. Therefore, the amount of data for meta-analyses relating to hand surgical issues can be significantly increased.
背景/目的:JAMAR握力计和马丁活力计是手外科医生日常工作中常用的工具。本调查主要关注为这两种仪器的测量值建立有效的转换因子,以及研究解剖特征、年龄和性别对最大测量握力的影响。
我们记录了339例患者的既往病史数据和特定解剖状况,使用两种仪器的所有刻度测量最大握力。
比较两种仪器的所有28种设置,我们发现相关性为中度到非常高。使用JAMAR握力计时,手部解剖结构对握力的影响比使用马丁活力计时更大。
高再现性使我们能够为两种工具的所有设置计算测量数据转换的乘法因子。因此,与手外科问题相关的荟萃分析的数据量可以显著增加。
