PURPOSE/BACKGROUND: Hand-held dynamometers are commonly used to assess plantarflexor strength during rehabilitation. The purpose of this study was to determine the concurrent validity of measuring plantarflexion force using a hand-held dynamometer (HHD) as compared to an electromechanical dynamometer as the gold standard. The hypothesis was that plantarflexor forces obtained using a hand-held dynamometer would not show absolute agreement with a criterion standard.
Concurrent validity assessment for a diagnostic strength testing device.
Institutional clinic and research laboratory.
Volunteer sample of healthy university students (N=20, 10 women, 10 men; 25.9±4.1 years).
Maximal plantarflexion strength was measured using both a HHD and an electromechanical dynamometer (EMD) as a criterion measure.
Plantarflexor force measures with the HHD were significantly different (p<0.01) and not correlated with plantarflexor forces measured using the EMD for either limb (R(2) ≤ 0.09).
Plantarflexor strength measurements acquired using HHD are different from those acquired using an EMD and are likely influenced by the strength of the examiner.

目的/背景:在康复过程中,手持测力计常用于评估跖屈力量。本研究的目的是确定与作为金标准的机电测力计相比,使用手持测力计(HHD)测量跖屈力的同时效度。假设是使用手持测力计获得的跖屈力与标准测量方法不会显示出完全一致性。
对一种诊断性力量测试设备进行同时效度评估。
机构诊所和研究实验室。
健康大学生志愿者样本(N = 20,10名女性,10名男性;25.9±4.1岁)。
使用HHD和作为标准测量方法的机电测力计(EMD)测量最大跖屈力量。
HHD测量的跖屈力有显著差异(p<0.01),且与使用EMD测量的任一肢体的跖屈力均无相关性(R²≤0.09)。
使用HHD获得的跖屈力量测量结果与使用EMD获得的结果不同,并且可能受检查者力量的影响。
