The impact of spinal cord stimulation for upper extremity complex regional pain syndrome on level of function

Abstract

Background/aims Spinal cord stimulation (SCS) is able to provide significant pain relief in individuals with complex regional pain syndrome (CRPS). Less is known about how this treatment impacts on function, particularly from the patients' perspective. This qualitative exploratory study was part of a larger service evaluation into current and future management of this patient group. This evaluation aimed to gain insight into the influence of SCS on daily activity and work and to explore the patients' journey from symptoms to diagnosis, SCS implant and afterwards. Methods A purposive sample of three patients took part in semi-structured interviews. Thematic content analysis of the data was then used to extract themes and subthemes. Results Thematic content analysis identified two emerging concepts: freedom and conflict. Within these two concepts, seven subthemes were apparent. Although participants described feelings of independence due to the effect of SCS on activity levels, other less encouraging issues were identified. These include a dependence on the stimulator, a lack of control over the future, and a perceived lack of understanding of their condition by others. Conclusion How these concepts relate to patients' ability to return to work is explored and areas for further research are identified.
