Abstract
Introduction: Sensory discrimination training has demonstrated improvements in two-point discrimination and pain reduction in people with chronic pain. We tested the feasibility and acceptability of a novel Sensory Training System (STS) device in the homes of people with Type 1 Complex Regional Pain Syndrome (CRPS).
Methods: Participants meeting CRPS diagnostic criteria were invited to use the STS for a minimum of 30 minutes per day for 30 days. Device usage data were captured by the STS. Assessments at baseline and after 30 days were: two-point discrimination ability, pain intensity and interference, sensitivity and emotions towards CRPS limb. Qualitative interviews were conducted at the end of the study to capture participants' feedback on the device.
Results: A total of 10 participants (female n = 7) completed the study. Participants' mean age was 56.4 years (range: 24-78 years), and mean disease duration was 9.37 years (range: 4.25-26.5). Eight had lower limb CRPS. The mean STS device use was 27.3 ± 3.4 days and mean daily usage of training games was 00:27:11 ± 00:07:52 (hh:mm:ss). No patterns or trends were evident between device usage and outcome data.
Conclusion: This feasibility study of a home-based STS for people with CRPS revealed key areas for improvement in the device's hardware and software and outlined the challenges of development and testing during the COVID-19 pandemic, while also capturing valuable usability insights from participant feedback. Key recommendations include early and ongoing collaboration with users, securing sufficient funding, ensuring correct device setup by participants, conducting interim analysis, and using online tools to enhance participant experience and data collection.
Study registration: The study was registered with ISRCTN registry on 28th May 2021 (https://doi.org/10.1186/ISRCTN89099843).
期刊介绍：
British Journal of Pain is a peer-reviewed quarterly British journal with an international multidisciplinary Editorial Board. The journal publishes original research and reviews on all major aspects of pain and pain management. Reviews reflect the body of evidence of the topic and are suitable for a multidisciplinary readership. Where empirical evidence is lacking, the reviews reflect the generally held opinions of experts in the field. The Journal has broadened its scope and has become a forum for publishing primary research together with brief reports related to pain and pain interventions. Submissions from all over the world have been published and are welcome. Official journal of the British Pain Society.
