Increased center of pressure excursions are well documented in patients with non-specific neck pain. While a linear relationship between pain intensity and postural sway has been described in low back pain patients, no such investigation has been conducted in adults with non-specific neck pain.
Seventy patients with non-specific neck pain and a matching number of healthy controls were enrolled. Center of pressure parameters were measured by three static bipedal standing tasks of 90 sec duration each with eyes closed on a force platform. The pain intensity was assessed by a numeric rating scale (NRS), an equal number of patients (n=10) was enrolled per pain score.
The results confirmed an increased postural sway in pain sufferers compared to healthy controls. In addition, a significant and linear increase in postural sway was observed with higher pain ratings. Statistically significant changes in sway were reached with an incremental change in NRS scores of two to three points.
Mean velocity and sway area are closely related to self-reported pain scores in neck pain patients. This relationship has implications for clinical applications such as an objective monitoring tool for patients under treatment or rehabilitation.
压力中心偏移增加在非特异性颈部疼痛患者中已有充分记录。虽然在腰痛患者中已描述了疼痛强度与姿势摆动之间的线性关系，但尚未对非特异性颈部疼痛的成年人进行此类研究。
招募了70名非特异性颈部疼痛患者和数量匹配的健康对照者。通过在测力平台上进行三次持续90秒的静态双足站立任务来测量压力中心参数，每次任务时均闭眼。采用数字评分量表（NRS）评估疼痛强度，每个疼痛评分等级纳入相等数量的患者（n = 10）。
结果证实，与健康对照者相比，疼痛患者的姿势摆动增加。此外，随着疼痛评分升高，观察到姿势摆动显著且呈线性增加。NRS评分每增加两到三分，摆动就会出现统计学上的显著变化。
平均速度和摆动面积与颈部疼痛患者自我报告的疼痛评分密切相关。这种关系对临床应用具有启示意义，例如可作为治疗或康复患者的客观监测工具。
