Sensory Processing Patterns in People With Complex Regional Pain Syndrome

Abstract

Limited literature exists investigating the relationship between sensory processing and complex regional pain syndrome (CRPS). This study aimed to identify and understand sensory processing patterns for people with CRPS. This study employs a cross-sectional survey design. Participants were a sample of convenience and completed two electronic surveys: a demographic survey and the Adolescent/Adult Sensory Profile (AASP). More than 90% of participants (n=62) were female and White or White in combination. Participants 18 to 64 perceived sensory experiences in subtypes of low registration, sensory sensitivity, and sensation avoiding, while they demonstrated lower perceived levels of sensation seeking. Participants above 65 reported experiencing sensory sensitivity and sensation avoiding “much more than most people.” There were patterns between sensory sensitivity to low registration and sensation avoiding, regardless of age. Above 65, low registration and sensation avoiding were significantly related. Patterns exist within sensory processing subtypes in people with CRPS.

Plain Language Summary

Sensory Processing and Complex Regional Pain Syndrome

Little is known about how sensory systems may or may not increase someone’s likelihood to get complex regional pain syndrome (CRPS) after an injury. Likewise, it is unknown if sensory systems impact recovery. It is thought that there is a connection between people’s sensory systems and how CRPS looks in each person. We wanted to see what sensory patterns were reported by people diagnosed with CRPS. Two surveys were sent to people belonging to a CRPS support organization. Differences in sensory patterns were identified in people 18 to 64 and above 65. Possible ways this influences CRPS are discussed. Ideas for future research are talked about based on what was found.
