METHODS: Cross-sectional observational study.
METHODS: Thirty-nine participants (11 males) with PFP were included. Dependent variables were steps per day and minutes of MVPA. Independent variables were pain self-efficacy and pain catastrophizing, measured by the pain self-efficacy questionnaire and the pain catastrophizing scale. Participants were given an ActiGraph wGT3X-BT for 7 days to assess physical activity. Correlations were assessed between psychological measures and physical activity, and a simple linear regression was performed on psychological variables that correlated with physical activity. Alpha was set a priori at P < .05.
RESULTS: Pain self-efficacy scores displayed a moderate association with steps per day (rho = .45, P = .004) and a weak association with MVPA (rho = .38, P = .014). Pain catastrophizing scores exhibited no significant associations with physical activity (P < .05). Regression models affirmed pain self-efficacy scores as significant predictors of both steps per day (F1,37 = 10.30, P = .002) and MVPA (F1,37 = 8.98, P = .004).
CONCLUSIONS: Psychological measures continue to demonstrate value to clinicians treating PFP. Pain self-efficacy scores were moderately associated with steps per day and weakly associated with MVPA, explaining nearly a fifth of the variation in physical activity. Clinicians should prioritize the assessment of pain self-efficacy when treating individuals with PFP, potentially employing psychological interventions to improve physical activity in the PFP population.
方法:横断面观察性研究。
方法:纳入了39名PFP患者(11名男性)。因变量是每天的步骤和MVPA的分钟数。独立变量是疼痛自我效能感和疼痛灾难,通过疼痛自我效能感问卷和疼痛灾难感量表进行测量。参与者被给予ActiGraphwGT3X-BT7天以评估身体活动。评估了心理措施和身体活动之间的相关性,并对与身体活动相关的心理变量进行了简单的线性回归。α被先验地设定为P<.05。
结果:疼痛自我效能评分显示出与每天步数的中度关联(rho=.45,P=.004),与MVPA的弱关联(rho=.38,P=.014)。疼痛灾难评分与体力活动无显著相关性(P<0.05)。回归模型确认疼痛自我效能评分是每天两个步骤(F1,37=10.30,P=0.002)和MVPA(F1,37=8.98,P=0.004)的显着预测因子。
结论:心理措施继续证明临床医生治疗PFP的价值。疼痛自我效能评分与每天的步数中度相关,与MVPA弱相关,解释了近五分之一的体力活动变化。临床医生在治疗PFP患者时,应优先评估疼痛自我效能感,可能采用心理干预措施来改善PFP人群的体育锻炼。
