The effect of psychomotor physical therapy on health-related quality of life, pain, coping, self-esteem, and social support.

Abstract

Norwegian psychomotor physiotherapy (NPMP) is commonly applied for patients with long-lasting pain and psychological symptoms. The approach is based on a bio-psychosocial model of health and might have benefits to physical, psychological, and physical domains of health-related quality of life (HRQOL). No previous randomized controlled clinical trials have been performed to examine the effectiveness of NPMP as individual treatment. The aim was therefore to assess the effect of a 6-month intervention of NPMP on HRQOL and on pain, coping, social support, and self-esteem. The study was a pragmatic randomized controlled trial comparing an intervention group with a control group. Participants were recruited from 36 physiotherapists specialized in NPMP, working in private practice. The intervention group received NPMP once weekly for 6months, whereas the control group received no intervention. Measurements were performed at baseline and after 6months. A total of 105 participants were included. HRQOL was measured by the 36-item Short Form Health Survey, SF-36. To examine the effect of the intervention, independent sample t tests were performed with the "difference in mean values," delta (=∆, posttest result-baseline result). Significant differences between the two groups were observed in six of the eight SF-36 domains: Physical Functioning, Bodily Pain, General Health, Mental Health, Social Functioning, and Vitality. Effect size ranged from 0.9 for Vitality to 0.3 for Role Physical and Role Emotional. Furthermore, there was a significant difference between groups regarding pain and self-esteem in favour of the intervention group. The Cohen's d effect sizes of the different dimensions of HRQOL ranged from 0.3 to 0.9 with a median of 0.6. The results of this study demonstrate that 6-month intervention of NPMP increased HRQOL and self-esteem as well as reduced pain.
