Background & Aims

Kinesiophobia is considered as a crucial factor to predict post-operative pain and functional performance and quality of life in people after total hip replacement1)2). However, there has been no study to investigate the relationship between pre-operative kinesiophobia and post-operative pain, pain-related factors and physical performance in the early phase after total hip replacement(THR). Therefore, the aim of the study elucidate the relationship between pre-operative kinesiophobia and postoperative pain, physical and pain-related variables after THR.

Methods

A prospective, prognostic cohort study was implemented. 118 patients underwent primary THR were recruited consecutively. The mean of BMI and age were . All surgery was performed as posterior lateral approach. The variables were measured at 4 weeks after THR which included hip flexion and extension range of motion, hip abductor, knee extensor maximum muscle strength and 10m maximum gait speed. Pain catastrophizing scale(PCS), Short-Form McGill Pain Questioner(SF-MPQ-2), and Central Sensitization Inventory(CSI), as pain severity and pain-related factors. The subjects were divided into two groups based on TSK score: the high kinesiophobia group (TSK > 37) and the low kinesiophobia group (TSK ? 37)
Demographic data were analyzed by descriptive statistics. Comparisons between the high and the low kinsiophobia groups’ patient characteristics were performed by Mann–Whitney U tests (for continuous variables). A P-value<0.05 was considered statistically significant.

Results

There were 78 patients (63%,?IQR43(41-47) ) with high kinesiophobia and 40 patients(36%, IQR34.5(30-36)) with no kinesiophobia. Patients with and without kinesiophobia were not statistically different regarding age and body mass index (P = 0.31, P = 0.76, respectively). CSI, PCS, TSK, and SF-MPQ-2 were statistically significant with patients with kinisiophobia(P=0.002, P=0.017, P=0.0001, P=0.01, respectively).

Conclusions

Physical function at 4 weeks after THR was not statistically significant including hip abductor and knee extensor peak torque and hip flexion, extension range of motion and 10m maximum gait speed to kinesiophobia. However, pain severity and pain-related
aspects including SF-MPQ-2, CSI, PCS and TSK were statistically significant. The result of the study can indicate the relevance of pre-operative high kinesiophobia and post-operative pain severity and pain-related factors such as pain catastrophizing, and central sensitization rather than functional performance.
