This study examined the Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale (B-CRPS-BPDS) in CRPS and found that the proposed revised r-B-CRPS-BPDS is a valid measure of body perception disturbances in CRPS. The r-B-CRPS-BPDS showed positive relationships with various clinical variables, indicating its utility in assessing body perception disturbances in CRPS.
The Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale (B-CRPS-BPDS) measures alterations in body perception. We assessed its internal consistency, known group validity, construct validity, and associations with demographic and clinical characteristics. We also evaluated changes in, and baseline predictors of B- CRPS-BPDS scores at followup. We included people with CRPS (N = 114) and pain-free controls (N = 69). People with CRPS obtained higher scores than pain-free controls on all B-CRPS-BPDS items, except the item on attention. Because this item also had an insufficient corrected item-total correlation, we propose a revised B-CRPS-BPDS (r-B-CRPS-BPDS) excluding this item. The internal consistency of the r-BCRPS-BPDS was good. The r-B-CRPS-BPDS showed a large positive relationship with motor neglect-like symptoms, indicating good construct validity. The r-B-CRPS-BPDS showed positive relationships with pain intensity, fear of movement, depression, and upper limb disability. There were no independent relationships with handedness, affected side, affected limb, disease duration, CRPS severity score, tension, anger, fatigue, confusion, and vigour. Finally, r-B- CRPS-BPDS scores did not consistently change over time. Our results demonstrate the utility of the r-B-CRPS-BPDS for measuring body perception disturbances in CRPS. Perspective: This article evaluates the validity of the Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale ( B-CRPS-BPDS) in CRPS, and assesses relationships with demographic and clinical variables. The proposed revised B-CRPS-BPDS appears to be a valid measure of body perception disturbances in CRPS. (C) 2021 by United States Association for the Study of Pain, Inc.
