The purpose of this study was to present normative values for thumb abduction and adduction and also to present measures of reliability of the measuring system arising from the use of the Ab-Adductometer. With the Ab-Adductometer, we obtained abductor and adductor measurements of intrinsic muscle strength of the healthy hand thumb in 600 volunteers. Handgrip strength values were obtained with the Jamar dynamometer. Age and male-female specific reference ranges for the Ab-Adductometer and the Jamar dynamometer are presented. This study, with a very large number of volunteer subjects, 600, presents reference ranges for pure palmar adduction and abduction of the thumb. The results indicate that the Ab-Adductometer is a clinically useful device for the purpose of quantitatively measuring thumb adduction and abduction strength at various starting angles of thumb abduction relative to the plane of the palm. The device may be especially helpful in the evaluation of compressive neuropathies of the median or ulnar nerves such as carpal tunnel syndrome or cubital tunnel syndrome as well as for primary disease of the peripheral nerves that affect intrinsic muscles and for thumb function in proximal conditions such as tetraplegia and brachial plexopathy.
本研究的目的是给出拇指外展和内收的标准值，并展示使用外展 - 内收测量仪所产生的测量系统的可靠性指标。使用外展 - 内收测量仪，我们对600名志愿者健康手拇指的固有肌力量进行了外展肌和内收肌测量。使用Jamar握力计获得握力值。给出了外展 - 内收测量仪和Jamar握力计的年龄及男女特定参考范围。这项研究有600名大量志愿者受试者，给出了拇指单纯掌侧内收和外展的参考范围。结果表明，外展 - 内收测量仪是一种临床上有用的设备，用于在拇指相对于手掌平面的各种起始角度定量测量拇指内收和外展力量。该设备在评估正中神经或尺神经的压迫性神经病变（如腕管综合征或肘管综合征）以及影响固有肌的周围神经原发性疾病和诸如四肢瘫和臂丛神经病变等近端疾病中的拇指功能时可能特别有帮助。
