The purpose of this investigation was to examine the influence of bead and neck (HN) position in the transverse plane on the static production of elbow flexion force in the involved (paretic) upper extremity of patients with hemiparesis. Thirty-one patients who had experienced a cerebrovascular accident a mean of 44 days before testing participated in the study. Static elbow flexion force was tested with a hand-held dynamometer, twice with the HN rotated toward the paretic side and twice with the HN rotated toward the nonparetic side. Elbow flexion force did not differ with the HN in the two positions (F = 0.008, p = 931). Results of this study support the conclusion that HN position in the transverse plane does not influence the production of static elbow flexion force on the paretic side in patients with stroke. Clinicians, therefore, may wish to reexamine any emphasis they place on HN position for facilitating elbow flexion force production on the paretic side of patients with hemiparesis.
本研究的目的是探讨在偏瘫患者患侧（瘫痪侧）上肢中，珠子与颈部（HN）在横平面上的位置对静态屈肘力产生的影响。31名在测试前平均44天经历过脑血管意外的患者参与了该研究。使用手持式测力计测试静态屈肘力，HN向瘫痪侧旋转时测试两次，HN向非瘫痪侧旋转时也测试两次。在两个位置上，屈肘力并不因HN位置不同而有差异（F = 0.008，p = 0.931）。本研究结果支持以下结论：在横平面上，HN位置并不影响中风患者患侧静态屈肘力的产生。因此，临床医生可能需要重新审视他们对HN位置的重视程度，即其是否有助于偏瘫患者患侧屈肘力的产生。
