The Management of Complex Regional Pain Syndrome-associated Foot Pain using a Poron Insole, a Sponge Upper Padding, and a Post-operative Shoe: A Case Report
Bibliographic record
Abstract
Background: Pain from complex regional pain syndrome (CRPS) is frequently refractory to various treatment methods. Here, we present a case wherein foot pain from CRPS I was managed by applying an insole made from poron (a soft polyurethane foam and highly absorbent material for shock reduction), a sponge upper padding, and a post-operative shoe. Case Presentation: A 47-year-old female patient with CRPS I on her left foot complained of pain for a few months, which was aggravated while standing and walking [numeric rating scale (NRS): 8]. She had a history of a linear fracture in the distal portion of the left 1st metatarsal bone 5 months ago, and the pain from CRPS started 2 months after the fracture. We believed that the aggravated pain during standing and walking was allodynia. We utilized a poron insole, a sponge upper padding, and a post-operative shoe to reduce the pressure and friction loading on her left foot. 1 month after this intervention, the patients’ pain during standing and walking was found to have reduced from NRS 8 to NRS 3. At her 3- and 6-month follow-ups, the degree of pain was sustained at NRS 3. Conclusion: We believe that the reduction of allodynia using materials, which can absorb mechanical pressure and friction of the foot, can help manage pain from CRPS.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
