To determine the reliability and measurement error of measurements of intrinsic muscle strength of a new hand-held dynamometer (the Rotterdam Intrinsic Hand Myometer [RIHM]).
With the RIHM we obtained repeated measurements of the intrinsic muscle strength of the hand in 27 patients with peripheral nerve injury of the ulnar and/or median nerve in different stages of rehabilitation. The average time period after injury was 4.4 years (range, 99 days-11 years).
Differences between 2 measurements greater than 6.3 N were interpreted as a real change in assessing the strength of the abduction of the little and index finger; for the median innervated muscles of the thumb this value was 16 N.
In patients with nerve injuries the muscle strength is usually assessed with manual muscle strength testing and grip- and pinch-strength dynamometers. Preferably the intrinsic muscle strength should be measured in isolation and quantitatively. The RIHM is a new dynamometer that allows for measurements of the intrinsic muscle strength in isolation with reliability comparable to grip and pinch measurements.
确定一种新型手持式测力计（鹿特丹手部固有肌测力计[RIHM]）测量手部固有肌力量的可靠性和测量误差。
我们使用RIHM对27例尺神经和/或正中神经周围神经损伤患者在康复不同阶段的手部固有肌力量进行了重复测量。受伤后的平均时间为4.4年（范围为99天至11年）。
两次测量之间的差异大于6.3 N被解释为在评估小指和示指外展力量时的实际变化；对于拇指的正中神经支配肌，该值为16 N。
在神经损伤患者中，通常使用徒手肌力测试以及握力和捏力测力计来评估肌肉力量。最好单独且定量地测量手部固有肌力量。RIHM是一种新型测力计，能够单独测量手部固有肌力量，其可靠性与握力和捏力测量相当。
