The purpose of this study was to determine the optimal scoring methods for measuring strength of the more-affected hand in patients with stroke by examining the effect of reducing measurement errors. Three hand-strength tests of grip, palmar pinch, and lateral pinch were administered at two sessions in 56 patients with stroke. Five scoring methods were used to present the strength scores. The smallest real difference was used to provide information on the measurement error. The smallest real difference percentage was used to compare the effect on minimizing the error. Using mean score of tests for nonspastic patients carried out at least twice was found to be advisable to minimize measurement errors in the grip, palmar pinch, and lateral pinch tests. However, the use of hand-strength tests for patients with spasticity is limited because of the relatively high measurement errors.
本研究的目的是通过检查减少测量误差的效果，确定测量中风患者患侧手力量的最佳评分方法。对56例中风患者分两次进行了握力、掌侧捏力和侧方捏力三项手部力量测试。使用了五种评分方法来呈现力量得分。最小真实差异用于提供测量误差信息。最小真实差异百分比用于比较最小化误差的效果。发现对非痉挛患者至少进行两次测试的平均得分，有助于在握力、掌侧捏力和侧方捏力测试中最小化测量误差。然而，由于测量误差相对较高，手部力量测试在痉挛患者中的应用受到限制。
