Maximum voluntary isometric contraction (MVIC) is a standardized method for measurement of muscle strength in patients with neuromuscular disease. Values obtained from MVIC testing are difficult to interpret at present as normative data are limited. The objective of this study was to generate reference values for MVIC. A convenience sample of 494 healthy men and women aged 20-76 years was recruited. MVIC testing was performed on nine muscle groups bilaterally: neck flexors, shoulder abductors, shoulder adductors, elbow and knee flexors and extensors, and hip and ankle flexors. MVIC was performed using the Quantitative Muscle Assessment system. Age and sex related reference values were calculated for each muscle group using quantile regression. A clinical reporting system was developed to facilitate interpretation of patient values with reference to normal percentiles. Reference values generated from this study can be used to determine the presence and extent of muscle weakness in a given population and to evaluate the effectiveness of treatment interventions.
最大自主等长收缩（MVIC）是测量神经肌肉疾病患者肌肉力量的一种标准化方法。由于目前规范数据有限，MVIC测试获得的值难以解释。本研究的目的是生成MVIC的参考值。招募了494名年龄在20 - 76岁之间的健康男性和女性作为便利样本。对九个肌肉群进行双侧MVIC测试：颈部屈肌、肩部外展肌、肩部内收肌、肘部和膝部屈肌与伸肌，以及髋部和踝部屈肌。使用定量肌肉评估系统进行MVIC测试。使用分位数回归为每个肌肉群计算年龄和性别相关的参考值。开发了一个临床报告系统，以便参照正常百分位数来解读患者的值。本研究生成的参考值可用于确定特定人群中肌肉无力的存在和程度，并评估治疗干预的效果。
