Tai Chi is effective in treating knee osteoarthritis: A randomized controlled trial
Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame — the usual design — would never have seen this work. It is one of the works that make the case for inverting the frame.
Machine scores (provisional)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
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.

Abstract
OBJECTIVE: To evaluate the effectiveness of Tai Chi in the treatment of knee osteoarthritis (OA) symptoms. METHODS: We conducted a prospective, single-blind, randomized controlled trial of 40 individuals with symptomatic tibiofemoral OA. Patients were randomly assigned to 60 minutes of Tai Chi (10 modified forms from classic Yang style) or attention control (wellness education and stretching) twice weekly for 12 weeks. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score at 12 weeks. Secondary outcomes included WOMAC function, patient and physician global assessments, timed chair stand, depression index, self-efficacy scale, and quality of life. We repeated these assessments at 24 and 48 weeks. Analyses were compared by intent-to-treat principles. RESULTS: The 40 patients had a mean age of 65 years and a mean body mass index of 30.0 kg/m(2). Compared with the controls, patients assigned to Tai Chi exhibited significantly greater improvement in WOMAC pain (mean difference at 12 weeks -118.80 mm [95% confidence interval (95% CI) -183.66, -53.94; P = 0.0005]), WOMAC physical function (-324.60 mm [95% CI -513.98, -135.22; P = 0.001]), patient global visual analog scale (VAS; -2.15 cm [95% CI -3.82, -0.49; P = 0.01]), physician global VAS (-1.71 cm [95% CI -2.75, -0.66; P = 0.002]), chair stand time (-10.88 seconds [95% CI -15.91, -5.84; P = 0.00005]), Center for Epidemiologic Studies Depression Scale (-6.70 [95% CI -11.63, -1.77; P = 0.009]), self-efficacy score (0.71 [95% CI 0.03, 1.39; P = 0.04]), and Short Form 36 physical component summary (7.43 [95% CI 2.50, 12.36; P = 0.004]). No severe adverse events were observed. CONCLUSION: Tai Chi reduces pain and improves physical function, self-efficacy, depression, and health-related quality of life for knee OA.
