Research using the biopsychosocial model could find areas of improvement in the treatment of CLBP. This study attempts to find a relationship between Pain Catastrophizing (PC) and trunk movement patterns in CLBP Patients (N = 67) by performing retrospective data analysis on data collected by the Spine and Joint Centre in Rotterdam. Data was gathered from the Pain Catastrophizing Scale (PCS) and the Objective Back Coordination Analysis (ORCA), a trunk movement measurement method. The analysis was performed through linear regression between the variables, which resulted in small, significant negative correlations between total PCS scores and trunk range of motion (ROM) (r = -.204, p < .05) and total PCS scores and movement pattern abnormality when compared to asymptomatic controls (r = -.244, p < .05). These results indicate that a high PC tends to coincide with lower ROM and a lower level of movement pattern abnormality. No correlations were found between the Magnification subscale of the PCS and ROM or movement pattern abnormality. A possible explanation for these results is that heightened PC could lead to higher levels of compensatory muscle use in the lower back, making patients’ movement patterns approximate that of asymptomatic controls. Further research would be needed to confirm this.Show less

To do this, 8 participants filled out a 14 question Hospital Anxiety and Depression Scale (HADS) and afterwards were exposed to two conditions, a stress condition, and a neutral condition. Per test the participants were shown 3 neutral and 3 stressful stimuli in the form of a picture and were asked to bend forward 5 times per picture presentation. The range of motion of the low back, pelvis and the trunk and the level of arousal via skin conductance were measured. Results show no significant findings but that can be explained with the small participant group. Several findings were a higher level of arousal when presented with a stress stimulus compared to a neutral stimulus. Furthermore, the range of motion of the low back, trunk and pelvis are bigger in the neutral condition compared to the stress condition. The HADS score seems to have no relationship with the level of arousal. All these findings are based on a small group of participants, are possibly due to incidental finding and could be different with a bigger group of participants.Show less
