International respiratory societies recommend upper limb muscle strengthening in patients with chronic obstructive pulmonary disease (COPD). To design an adapted and effective muscle strengthening program, it is necessary to assess the muscle strength of muscle groups involved. The objective of this study was to assess the reliability and validity of measuring the maximum voluntary isometric strength of shoulder abductors, elbow flexors, and extensors using a handheld dynamometer.
Maximum voluntary isometric strength was measured using a handheld dynamometer, and the one repetition maximum test was performed using dumbbells. Three separate 24-h measurement sessions were conducted: the first 2 sessions (Day 0 and Day 1) by a physiotherapist and the third session (Day 2) by another physiotherapist.
Fifty-seven COPD patients (age: 65.7 ± 8.5; FEV1: 45.3 ± 18.9%) were included and 54 were analyzed across three measurement sessions. We found an excellent correlation for intra-rater measurements (p < 0.001; shoulder abductors: r = 0.84, elbow flexors: r = 0.94, elbow extensors: r = 0.89) and good to excellent correlation for inter-rater measurements (Day 0/Day 2: p < 0.01; shoulder abductors: r = 0.76, elbow flexors: r = 0.89, elbow extensors: r = 0.87; Day 1/Day 2: shoulder abductors: p < 0.01; r = 0.90, elbow flexors: r = 0.91 elbow extensors: r = 0.93). Poor to good concordances were observed between the maximum voluntary isometric strength and the one repetition maximum test for intra-rater measurements.
Handheld dynamometer is a reliable and valid tool for assessing upper limb muscle strength in clinical practice for COPD patients.

国际呼吸协会建议慢性阻塞性肺疾病（COPD）患者进行上肢肌肉强化训练。为设计一个合适且有效的肌肉强化训练方案，有必要评估相关肌肉群的肌力。本研究的目的是评估使用手持测力计测量肩外展肌、肘屈肌和肘伸肌最大自主等长肌力的可靠性和有效性。
使用手持测力计测量最大自主等长肌力，并使用哑铃进行一次重复最大负荷测试。进行了三个独立的24小时测量时段：前两个时段（第0天和第1天）由一名物理治疗师进行，第三个时段（第2天）由另一名物理治疗师进行。
纳入了57例COPD患者（年龄：65.7±8.5；第1秒用力呼气容积：45.3±18.9%），54例患者在三个测量时段进行了分析。我们发现评估者内测量具有极好的相关性（p<0.001；肩外展肌：r=0.84，肘屈肌：r=0.94，肘伸肌：r=0.89），评估者间测量具有良好到极好的相关性（第0天/第2天：p<0.01；肩外展肌：r=0.76，肘屈肌：r=0.89，肘伸肌：r=0.87；第1天/第2天：肩外展肌：p<0.01；r=0.90，肘屈肌：r=0.91，肘伸肌：r=0.93）。评估者内测量的最大自主等长肌力与一次重复最大负荷测试之间的一致性为差到良好。
在临床实践中，手持测力计是评估COPD患者上肢肌肉力量的可靠且有效的工具。
