Weight Loss and Exercise Walking Reduce Pain and Improve Physical Functioning in Overweight Postmenopausal Women with Knee Osteoarthritis
Bibliographic record
Abstract
We conducted an uncontrolled pilot study to determine the effects of a weight loss and walking program on knee pain and physical function in overweight and obese (body mass index; BMI [kg/m] 25-29.9 and BMI > or = 30, respectively) postmenopausal women with knee osteoarthritis (OA). Forty-eight such women completed self-report (Western Ontario and McMaster University Osteoarthritis Index (WOMAC)) and performance-based measures of physical function ("up and go" test, 6-min walk) and enrolled in a 6-month intervention that included weekly nutrition classes and an exercise-walking program. The intervention produced an average weight loss of 5.6 +/- 4.0 kg in the 30 women who completed the program. There also were significant improvements in the 6-min walk and on VO(2max). Improvements in the timed up and go test and on the WOMAC pain and function scores, however, were restricted only to women who were classified as obese at baseline. These findings suggest that a 6-month weight loss and walking program improves measures of physical functioning and pain in overweight and obese postmenopausal women with knee OA. Among obese women, functional improvement correlated with weight loss, encouraging continued emphasis on weight loss for managing knee OA.

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.
