(095) CHRONIC EPIDURAL SPINAL CORD STIMULATION AS A POTENTIAL TREATMENT FOR SEXUAL DYSFUNCTION IN WOMEN WITH SPINAL CORD INJURY
Bibliographic record
Abstract
Abstract Introduction Spinal cord injury (SCI) is a lifelong condition that affects approximately 294,000 individuals in the United States, with an estimated 17,900 new cases occurring each year. Despite sexual function being reported as a top priority to restore after injury, research on sexual dysfunction after SCI is scarce, especially among people with gynecological anatomy. One major challenge in treating female sexual dysfunction (FSD) after SCI is the heterogeneity of symptoms. Women can have impacted libido, genital sensitivity, lubrication, and/or ability to orgasm. This is further complicated by the comorbidities of bladder and bowel dysfunction, which are also common after SCI. Epidural spinal cord stimulation (eSCS) has emerged as a promising treatment for SCI, demonstrating positive results across various domains for motor-complete patients, including bladder, bowel, and sexual function. Objective The primary objective is to determine if chronic eSCS improves survey-reported sexual function after SCI in women. The secondary objective is to determine if chronic eSCS improves survey-reported bladder and bowel function. Methods Seven female participants who are motor and sensory complete after traumatic SCI with injury levels between cervical (C)6 and thoracic (T)10 were recruited for the study. Participants were implanted with a 16-contact paddle lead epidural spinal cord stimulation at the T11-T12 level and followed for 13 months. The Female Sexual Distress Scale (FSDS), Neurogenic Bowel Dysfunction Score (NBDS), and Neurogenic Bladder Symptom Score (NBSS) were administered monthly. Participants received continuous stimulation over 13 months. A generalized linear model was created for each outcome to examine trends in function over time with an alpha of 0.025 (Bonferroni corrected). Results In the first 6 participants analyzed, we found that sexual distress improves over time (p<0.001) in the largest series of women participants with SCI targeted for restoration of function (Figure 1). One woman reported restoration of orgasm after five years of chronic SCI. Additionally, we found a statistically significant improvement in bowel function as measured by the NBDS with stimulation (p<0.003) from the generalized linear mixed effects fit corresponding to the follow-up visit number. There were no statistically significant trends in the NBSS scores, however, one participant noted that she no longer uses an intermittent catheter to empty her bladder indicating functional improvements that are not captured by the survey. Conclusions Epidural SCS is a promising therapy to improve female sexual function after chronic SCI. Although quantitative surveys remain the most valid and reliable measures of pelvic organ function after SCI, we saw improvements in function that were not captured by the questionnaires. Still, we found significant improvements in validated surveys of bowel function and female sexual distress over time. These high-priority outcomes for women with SCI are potential targets of restoration using commercially available spinal cord stimulation.

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.
