Effects of Wu Qin xi Qigong exercise on physical functioning in elderly people with knee osteoarthritis: A randomized controlled trial
Bibliographic record
Abstract
AIM: Exercise therapy is a key intervention in the management of knee osteoarthritis (OA). This study aimed to test the 6-month effectiveness of Wu Qin Xi Qigong (WQXQ) exercise versus a conventional physical therapy (control group [CG]) on physical functioning in patients with early knee OA. METHODS: This study was a 6-month follow-up from a randomized controlled trial. Participants with knee OA were randomly allocated to the WQXQ or CG. Data from the Berg Balance Scale, Timed Up and Go Test, 6-Minute Walk Test, 30-Second Chair Stand Test, the Western Ontario and McMaster Universities Osteoarthritis Index, knee extension strength and knee flexion strength were collected before and after the 6-month intervention. RESULTS: Both treatment groups demonstrated large (20%-50%) and clinically relevant reductions in activity limitations, pain and knee instability, which were sustained at 6 months post-treatment. No differences in effectiveness between experimental and control treatment were found on Timed Up and Go Test, 6-Minute Walk Test, knee extension strength and knee flexion strength except for a higher Berg Balance Scale score (P = 0.029) and lower Western Ontario and McMaster Universities Osteoarthritis Index pain score (P = 0.031) in the WQXQ group. CONCLUSIONS: Both WQXQ and conventional physical therapy exercise programs were highly effective in reducing activity limitations and pain, and promoting balance and muscle power. WQXQ was found to be more effective in promoting balance and reducing pain than conventional physical therapy exercise in patients with knee OA. Geriatr Gerontol Int 2020; 20: 899-903.

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.
