目标。目的是确定慢性中风患者的上肢损伤和功能是否取决于主手或非主手是否受到影响。方法。93名社区居住的中风患者。采用改良Ashworth量表（音）、手机测力法（等长强度）、单丝法（感觉）、短暂疼痛量表（疼痛）、Chedoke手臂和手活动量表运动活动日志（麻痹性手臂使用）和重返正常生活指数（参与）形成损伤和功能模型。结果。对损伤和功能变量建立多变量分析模型（优势X严重性）。优势度对损伤模型有显著交互作用（P = 0.01），对功能模型无显著交互作用（P = 0.75）。张力、握力、疼痛等因变量均受到优势手的显著影响，表明优势手的损伤较小。除疼痛外，所有因变量均受严重性影响。结论。这项研究着眼于慢性中风患者的优势手与非优势手的影响。优势手受影响的个体比非优势手受影响的个体表现出更小的损伤。然而，优势对父母的手臂使用或日常生活活动的表现没有影响。建议进行前瞻性研究，进一步探讨手优势和卒中后功能的问题。
Objective. The purpose was to determine if upper extremity impairment and function in individuals with chronic stroke is dependent upon whether the dominant or non-dominant hand is affected. Methods. Ninety-three community-dwelling individuals with stroke. The Modified Ashworth Scale (tone), handheld dynamometry (isometric strength), monofilaments (sensation), Brief Pain Inventory (pain), Chedoke Arm and Hand Activity Inventory Motor Activity Log (paretic arm use), and Reintegration to Normal Living Index (participation) were used to form impairment and function models. Results. Multivariate analysis models (Dominance X Severity) were created for impairment and function variables. There was a significant interaction and main effect of Dominance for the impairment model (P = 0.01) but not the function model (P = 0.75). The dependent variables of tone, grip strength, and pain were all significantly affected by Dominance, indicating less impairment if the dominant hand was affected. All dependent variables except pain were affected by Severity. Conclusion. This study looked at the effect of the dominant hand being affected versus the nondominant in individuals with chronic stroke. Individuals with the dominant hand affected demonstrated less impairment than those with the nondominant hand affected. However, there was no effect of dominance on paretic arm use or performance in activities of daily living. Prospective studies to further explore the issue of hand dominance and poststroke function are suggested.
