Little is known about the association between fear of movement (kinesiophobia) and objectively measured physical activity (PA), the first 12 weeks after cardiac hospitalization.
To assess the longitudinal association between kinesiophobia and objectively measured PA and to assess the factor structure of kinesiophobia.
We performed a longitudinal observational study. PA was continuously measured from hospital discharge to 12 weeks using the Personal Activity Monitor. The PAM measures time spent per day in PA-intensity categories: light, moderate and heavy. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK) at four time points (hospital discharge, 3, 6 and 12 weeks). The longitudinal association between PA-intensity and kinesiophobia was studied with a random intercept cross lagged panel model (RI-CLPM). A RI-CLPM estimates effects from kinesiophobia on objectively measured PA and vice versa (cross-over effects), and autoregressive effects (e.g. kinesiophobia from one occasion to the next).
In total, 116 patients (83.6% male) with a median age of 65.5 were included in this study. On no occasion did we find an effect of kinesiophobia on PA and vice versa. Model fit for the original model was poor (X2: = 44.646 P<0.001). Best model fit was found for a model were kinesiophobia was modelled as a stable between factor (latent variable) and PA as autoregressive component (dynamic process) (X2 = 27.541 P<0.12).
Kinesiophobia and objectively measured PA are not associated in the first 12 weeks after hospital discharge. This study shows that kinesiophobia remained relatively stable, 12 weeks after hospital discharge, despite fluctuations in light to moderate PA-intensity.
在心脏住院后的前 12 周，人们对运动恐惧（运动恐惧症）与客观测量的身体活动（PA）之间的关联知之甚少。
评估运动恐惧症与客观测量的 PA 之间的纵向关联，并评估运动恐惧症的因子结构。
我们进行了一项纵向观察性研究。使用个人活动监测器（PAM）从出院到 12 周连续测量 PA。PAM 测量每天在 PA 强度类别（轻度、中度和重度）中花费的时间。在四个时间点（出院时、3、6 和 12 周）使用坦帕运动恐惧症量表（TSK）评估运动恐惧症。使用随机截距交叉滞后面板模型（RI-CLPM）研究 PA 强度与运动恐惧症之间的纵向关联。RI-CLPM 估计运动恐惧症对客观测量的 PA 的影响以及反之亦然（交叉影响），以及自回归效应（例如，一次到下一次的运动恐惧症）。
共有 116 名患者（83.6%为男性）纳入本研究，中位年龄为 65.5 岁。在任何情况下，我们都没有发现运动恐惧症对 PA 的影响，反之亦然。原始模型的拟合度较差（X2：= 44.646，P<0.001）。发现运动恐惧症被建模为稳定的间因素（潜在变量），PA 被建模为自回归成分（动态过程）的模型拟合度最佳（X2 = 27.541，P<0.12）。
在出院后的前 12 周内，运动恐惧症和客观测量的 PA 之间没有关联。这项研究表明，尽管轻度到中度 PA 强度波动，运动恐惧症在出院后 12 周内仍然相对稳定。
