简介：慢性脑卒中患者的躯干运动协调性不典型，由于躯干肌肉无力，他们在床上活动和转移技能方面存在困难。常规床旁临床检查无法量化脑卒中患者的躯干肌力。手持式测力计被广泛应用于四肢力量的量化，但其可靠性测试的躯干肌strength. Objective：本研究旨在探讨的可靠性手持式测力计量化躯干肌群在慢性stroke.Materials和方法：本可靠性研究进行了门诊临床设置的力量。该研究志愿者包括年龄在30至80岁之间、步行能力为10米的慢性中风患者。躯干屈肌、伸肌、朝向受影响最大和最小侧的旋转肌和双侧侧屈肌的强度通过使用手持式测力计的断裂测试来检查，并且等距强度以磅（lb.）报告。这些测试由两名物理治疗师在两个时间点独立进行，评估程序标准化。进行皮尔逊相关性检验以观察测力计强度测试的可靠性，即，结果：在85名研究对象中，51名躯干受累最多的是左侧，34名是右侧。本研究显示了一个很好的评价者内（0.88-0.98）和评价者间（0.84-0.96）的可靠性躯干肌力测试使用手持式测力计。结论：手持式测力计显示了良好的测试者内和测试者间的可靠性，以量化的躯干肌力在慢性脑卒中患者。因此，该工具可以很容易地在临床和康复环境中用于诊断和预后目的。
Introduction: Patients with chronic stroke show atypical coordination of trunk movement and they find difficulty during bed mobility and transfer skills due to weakness of trunk muscles. Routine bedside clinical examination fails to quantify the trunk muscle strength in patients with stroke. Handheld dynamometer is widely administered to quantify the strength of extremities, but its reliability on testing the trunk muscles strength is limited.Aim: This study aimed at examining the reliability of hand-held dynamometer to quantify the strength of trunk muscle groups in chronic stroke.Materials and Methods: This reliability study was conducted in outpatient clinical settings. Patients with chronic stroke aged between 30 and 80 years and an ambulatory capacity of 10-meter distance volunteered in the study. The strength of trunk flexors, extensors, rotators towards most and least affected sides and bilateral lateral flexors was examined by break test using hand-held dynamometer and the isometric strength was reported in pounds (lb.). These tests were carried out by two physical therapists independently at two time points and the assessment procedure was standardized. Pearson's correlation test was conducted to observe the reliability of dynamometer strength testing i.e., internal consistency of the measure and intra-class correlation coefficient (r).Results: Of the 85 study participants, 51 of them had most trunk involvement on the left side and 34 had it on the right side. This study showed an excellent intra-rater (0.88-0.98) and inter-rater (0.84-0.96) reliability of trunk muscle strength testing using hand-held dynamometer.Conclusion: Hand-held dynamometer showed excellent intra and inter tester reliability to quantify the trunk muscle strength in patients with chronic stroke. So this tool can easily be administered in clinical and rehabilitation settings for diagnostic and prognostic purposes.
