0941 Limb Movements in Sleep [LMS] and PTSD-related Physical Symptoms: Preliminary Observations
Bibliographic record
Abstract
Abstract Introduction Periodic Limb Movements in Sleep [PLMS] can be present in over 60% of Posttraumatic Stress Disorder [PTSD] patients versus about 10% in the general population. PTSD is often associated with physical complaints. In the general population PLMS can be associated with physical symptoms . To my knowledge the association of PLMS and physical complaints in PTSD has not been reported. Methods 106 PTSD patients [all from MAG’s practice] completed a battery of instruments. 44/106 patients (mean age+/-SD = 47.04+/-13.27 years; 89.6% female) met the inclusion criteria (no current use of benzodiazepines or narcotics; ability to have LMS ratings completed by bed partner). All participants met the DSM-5 criteria for moderate-to-severe PTSD during their initial consultation, with a Clinician Administered PTSD Scale for DSM-5 (CAPS-5) score of at least 55. The PTSD Checklist for DSM-5 (PCL-5) was used to obtain an index of the current PTSD severity (mean = 37.41, SD = 19.84; PCL-5 > 30 cut-off for PTSD). Limb Movements in Sleep [LMS] were considered a proxy for PLMS [ICSD3, 2014] and were measured using Item 10c of the Pittsburgh Sleep Quality Index [PSQI] [Buysse DJ,1989] where the patients’ bed partner rated the patients’ severity of “Legs twitching or jerking while they slept”; Low-LMS frequency included "< one time per week" or "not during the past month" and High-LMS frequency included " once or twice a week " and " three or more times a week".Physical symptoms were rated using the Pennebaker Inventory of Limbic Languidness [PILL][Pennebaker JW,1982] which rates 54 physical symptoms using the following scale: 1=Have never or almost never experienced the symptom; 2=Less than 3 or 4 times per year; 3=Every month or so; 4=Every week or so; and 5=More than once every week. Results The mean scores of 20/54 PILL items were significantly [ p< 0.05] lower between the Low- versus High-LMS groups. The total 54 item mean PILL score was significantly [p=0.002] greater in the PTSD group with High-LMS [PILL score of 105 ] versus the Low-LMS scores [PILL score of 73]. Conclusion PTSD patients with more frequent limb movements during sleep had greater daytime physical complaints. Support (if any) None

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.
