The effect of progressive resistance exercise program on female knee osteoarthritis
Bibliographic record
Abstract
Objective To discuss the effect of progressive resistance exercise (PRE) program on female knee osteoarthritis (KOA). Methods A prospective study including 92 female KOA patients was performed in the department of Rehabilitation and Orthopedics in second hospital of HeBei Medical university from August 2013 to September 2014, the average age was (55±11) years (rang from 40-70 years). All subjects were randomly divided into the experimental group (46 cases) and control group (46 cases). Subjects in experimental group participated PRE program and joint mobilization triple once a week. Subjects in the control group only participated joint mobilization. Assessments of pain, muscle strength, walking distance, function and quality of life were performed at baseline, 6 weeks and 12 weeks after surgery by a blinded assessor with The Western Ontario and McMaster Universities Osteoarthritis Index and the MOS item short from health survey (SF-36). After finishing the treatment, Satisfaction survey was conducted in all patients using Likert Scale. Results Both groups have one case dropped out, completed ratio of 12 months of follow-up was 96.7%. At 6 weeks and 12 weeks after surgery, VAS scores in experimental group were lower than control group [experimental group: 6 w: (6.0±1.8) scores, 12 w: (4.4±3.0) scores; control group: 6 w: (7.0±1.5) scores, 12 w: (6.5±2.5) scores]. Differences of VAS score between two groups had statistical significance (6 w: t=-2.573, P=0.022, 12 w: t=-2.721, P=0.001). WOMAC indexes in experimental group were higher than the control group [experimental group: 6 w: (40±14) scores, 12 w: (31±14) scores; control group: 6 w: (24±17) scores, 12 w: (38±13) scores], differences of WOMAC score between two groups had statistically significance (6 w: t=0.001, P=0.017, 12 w: t=-4.263, P=0.001). At 12 weeks postoperatively, the SF-36 scores of physical function and physical role limitation in the experimental group were higher than control group [experimental group: physical function: (50±22) scores, physical role limitation: (48±40) scores; control group: physical function: (32±17) scores, physical role limitation: (17±23) scores], differences of SF-36 score between two groups had statistically significance (physical function: t=-3.601, P<0.001, physical role limitation: t=-2.093, P=0.001). At 12 weeks postoperatively, the experimental group had better muscle strength than the control group [the experimental group: extensor: (11.1±4.9)kg, flexor: (8.6±2.7)kg; the control group: extensor: (6.9±4.2)kg, flexor: (6.3±2.4)kg], differences of 1 RM between two groups had statistically significance (extensor: t=-2.571, P=0.001, flexor: t=-4.882, P<0.001). The ratio of patient satisfaction of the experimental grup was significantly higher than the control group (χ2=17.997, P<0.05). Conclusion The PRE program was effective in reducing pain, improving function and stability of keen among female patients with KOA, our study demonstrate it is better than the traditional rehabilitation trainings.

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.
