Objective Clinical guidelines for the treatment of complex regional pain syndrome recommend multidisciplinary rehabilitation, yet limited evidence exists to support the effectiveness of this approach. Body perception disturbance, a common and debilitating feature of complex regional pain syndrome, is recommended by guidelines as important to treat. However, no study has yet explored whether disturbances change in response to multidisciplinary rehabilitation. We aimed to determine whether there is a change in body perception disturbance and pain following a two-week multidisciplinary rehabilitation program for complex regional pain syndrome. Methods Retrospective clinical data from complex regional pain syndrome patients who completed the program between September 2014 and December 2016 were extracted and anonymized. Data collected pre- and post rehabilitation comprising the Bath Body Perception Disturbance scale and a pain intensity numerical rating scale were analyzed. Results Thirty complete data sets were analyzed from a sample of 50 consecutive patient records. After the program, there was a significant reduction in body perception disturbance (P < 0.0001), strength of negative emotional feelings (P < 0.0001), and pain (P = 0.0038). There was a significant correlation between a change in disturbance and pain (r = 0.44, P = 0.024). No relationship was found between the duration of symptoms and changes in disturbance (r = 0.04, P = 0.82). Conclusions This study provides evidence that both body perception disturbance and pain reduce after rehabilitation. Findings suggest that targeting these disturbances may be important in reducing pain and may be a potentially useful measure for recovery. Controlled trials are required to confirm the effectiveness of rehabilitation and determine what factors are responsible for these reductions.
