The relationship between the functional status of the extremities and “core” stabilization in women with fibromyalgia
Bibliographic record
Abstract
Introduction The aim of this study was to examine the relationship between the functional status of the extremities and “core” stabilization in women with fibromyalgia (FM). Material and methods Fifty-seven women with FM were included. The Widespread Pain Index (WPI), Visual Analogue Scale-Pain (VAS-Pain), Symptom Severity Scale (SSS), Fibromyalgia Impact Questionnaire (FIQ), McGill Static endurance tests (trunk flexors endurance, trunk extensors endurance, lateral bridge tests), Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH), grip strength, Lower Extremity Functional Scale (LEFS), chair-stand test, pressure pain threshold and 6-minute walk test (6MWT) were used in evaluation. Results The trunk flexors endurance test showed a weak correlation with 6MWT (r = 0.392), DASH (r = –0.347), LEFS (r = 0.328) and WPI (r = –0.289). The trunk extensors endurance test showed a weak correlation with grip strength-right (r = 0.285), DASH (r = –0.301) and LEFS (r = 0.321) and a moderate correlation with grip strength-left (r = 0.407), chair-stand test (r = 0.470) and 6MWT (r = 0.524). The right lateral bridge test showed a weak correlation with grip strength-right (r = 0.271), DASH (r = –0.379), LEFS (r = 0.254), WPI (r = –0.306), average of maximal values of pressure pain threshold (r = 0.316) and average of mean values of pressure pain threshold (r = 0.337); it showed a moderate correlation with grip strength-left (r = 0.418) and 6MWT (r = 0.414). The left lateral bridge test showed a weak correlation with grip strength-right (r = 0.279), chair-stand test (r = 0.276), 6MWT (r = 0.359), DASH (r = –0.294), average of maximal values of pressure pain threshold (r = 0.315) and average of mean values of pressure pain threshold (r = 0.370); it showed a moderate correlation with grip strength-left (r = 0.502) (p < 0.05). Conclusions Core muscle endurance is associated with upper and lower extremity functional level and pain parameters in women with FM.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
