Osteoarthritis (OA) is the main cause of pain and disability in the elderly. The disease leads to chronic musculoskeletal pain, characterized by an abnormal excitability of pain conduction pathways, and lifestyle may interfere in this pathophysiological aspect. Thus, the aim of this study was to compare perceived pain, pressure pain threshold, and lifestyle of adult and elderly women with and without knee OA. A total of 143 women were recruited and divided into 2 groups: OA ( = 68) and control ( = 75). Volunteers were evaluated for pressure pain tolerance (algometry in vastus medialis and vastus lateralis muscles), perceived pain (visual analogue scale) and lifestyle (FANTASTIC questionnaire). Patients with OA of the present study presented higher weight ( = .001) and body mass index ( < .001) than controls. Results also revealed less tolerance to pressure pain ( < .001) and higher pain perception ( < .001) in patients with OA. OA group scored significantly lower in lifestyle questionnaire than controls ( = .03). Patients with OA in the present study who presented lifestyle scores below median presented significantly higher values of pain perception than the ones above it ( = .03). In conclusion, patients with OA present more sensitivity to pain, more perceived pain, and worse lifestyle than healthy individuals.
骨关节炎（OA）是老年人疼痛和残疾的主要原因。该疾病导致慢性肌肉骨骼疼痛，其特征是疼痛传导通路的异常兴奋性，而生活方式可能会干扰这一病理生理方面。因此，本研究的目的是比较有和没有膝骨关节炎的成年及老年女性的疼痛感知、压痛阈值和生活方式。总共招募了143名女性，并将她们分为两组：骨关节炎组（n = 68）和对照组（n = 75）。对志愿者进行压力疼痛耐受性（股内侧肌和股外侧肌的痛觉测量）、疼痛感知（视觉模拟量表）和生活方式（FANTASTIC问卷）评估。本研究中的骨关节炎患者比对照组体重更高（P = .001）且体重指数更高（P < .001）。结果还显示，骨关节炎患者对压力疼痛的耐受性更低（P < .001）且疼痛感知更高（P < .001）。骨关节炎组在生活方式问卷中的得分显著低于对照组（P = .03）。本研究中生活方式得分低于中位数的骨关节炎患者的疼痛感知值显著高于得分高于中位数的患者（P = .03）。总之，与健康个体相比，骨关节炎患者对疼痛更敏感，疼痛感知更强，生活方式更差。
