Effects of a Rehabilitation Program Combined with Pain Management That Targets Pain Perception and Activity Avoidance in Older Patients with Acute Vertebral Compression Fracture: a Randomised Controlled Trial

Abstract

This study aimed to investigate the effect of a rehabilitation program combined with pain management targeting pain perception and activity avoidance on multifaceted outcomes in older patients with acute vertebral compression fractures (VCFs). We randomised 65 older adults with acute VCFs to either an intervention group (n = 32), involving usual rehabilitation combined with pain management that targeted pain perception and activity avoidance, or a control group (n = 33), involving only usual rehabilitation. The usual rehabilitation was initiated immediately after admission. All patients were treated conservatively. Pain management aimed to improve the patients’ daily behaviour by increasing their daily activities despite pain, rather than by focusing on eliminating the pain. Pain intensity and psychological statuses such as depression, pain catastrophising, and physical activity levels were assessed on admission. Two weeks postadmission and at discharge, physical performance measures were assessed along with the above-given measurements. A significant main effect of the group was observed for the intensity of lower back pain, favouring the intervention group (F = 5.135, p=0.027). At discharge, it was significantly better in the intervention group than in the control group (p=0.011). A time-by-group interaction emerged for magnification of the pain catastrophising scale (p=0.012), physical activity levels (p<0.001), and six-minute walking distance (p=0.006), all favouring the intervention group. Rehabilitation programs combined with pain management targeting pain perception and activity avoidance could be an effective conservative treatment for older patients with acute VCFs.
