Neck and shoulder pain is a common disorder which is often associated with a low-pressure pain threshold (PPT) of muscle tissues as manifested by hyperalgesia on palpation or the use of a pressure algometer. The objective of the present study was to evaluate the intratester repeatability of pressure algometer (Force-Five) on the neck and shoulder area in women with neck pain. The study was cross-sectional with single-group repeated measurements. PPT measurements in 20 women with chronic non-specific neck pain were measured on consecutive days at the levator scapulae, at two points on the trapezius muscles on each side and at the sternum as the only non-muscular site. The intratester repeatability of the PPT measurements was satisfactory or good (Intraclass correlation coefficient (ICC 0.78-0.93). The coefficient of repeatability ranged from 16.8 to 24.4N/cm2 and the coefficient of variation ranged from 10% to 22%, depending on the site tested. Considerable individual variation was observed when consecutive measures were analysed against their mean. On the group level the repeatability of the measurements allows the pressure algometer to be used for research purposes. However, on the individual level, due to the considerable variation found in the PPT results, caution is advised when interpreting the results in clinical practice.
颈部和肩部疼痛是一种常见病症,通常与肌肉组织的低压力疼痛阈值(PPT)相关,表现为触诊或使用压力痛觉计时有痛觉过敏。本研究的目的是评估压力痛觉计(Force - Five)在颈部疼痛女性的颈部和肩部区域测量的测试者内重复性。该研究为单组重复测量的横断面研究。对20名患有慢性非特异性颈部疼痛的女性,连续数天在肩胛提肌、双侧斜方肌上的两个点以及作为唯一非肌肉部位的胸骨处测量PPT。PPT测量的测试者内重复性令人满意或良好(组内相关系数(ICC)为0.78 - 0.93)。重复性系数在16.8至24.4N/cm²之间,变异系数在10%至22%之间,具体取决于测试部位。当对连续测量值与其均值进行分析时,观察到个体差异较大。在群体水平上,测量的重复性使压力痛觉计可用于研究目的。然而,在个体水平上,由于PPT结果存在较大差异,在临床实践中解释结果时建议谨慎。
