Six hours of task-oriented training optimizes walking competency post stroke: a randomized controlled trial in the public health-care system of South Africa
Bibliographic record
Abstract
OBJECTIVE: To evaluate a minimal dose intervention of six 1-hour sessions of task-oriented circuit gait training including a caregiver over a 12-week period to persons post stroke in the South African public health sector. DESIGN: Stratified, single blinded, randomized controlled trial with three intervention groups. PARTICIPANTS: Persons post stroke ( n = 144, mean age 50 years, 72 women), mean 9.5 weeks post stroke. INTERVENTIONS: Task group ( n = 51)-accompanied by a caregiver; task-oriented circuit gait training (to improve strength, balance, and task performance while standing and walking). Strength group ( n = 45); strength training of lower extremities while sitting and lying. Control group ( n = 48); one 90-minute educational session on stroke management. MEASURES: The six-minute walk test (6MinWT) was the primary outcome; the secondary outcomes included comfortable and fast gait speeds, Berg Balance Scale (BBS), and Timed Up and Go (TUG). Particpants evaluated at baseline, post intervention (12 weeks), and at follow-up 12 weeks later. Change scores were compared using generalized repeated measures analysis of variance (ANOVA). RESULTS: Task group change scores for all outcomes post intervention and at follow-up were improved compared to the other groups ( P-values between 0.000005 and 0.04). The change scores (mean, 1SD) between baseline and follow-up for the Task, Strength, and Control groups, respectively, were as follows: 6MinWT:119.52 m (81.92), 81.05 m (79.53), and 60.99 m (68.38); comfortable speed 0.35 m/s (0.23), 0.24 m/s (0.22), and 0.19 m/s (0.21); BBS: 9.94 (7.72), 6.93 (6.01), and 5.19 (4.80); and TUG: -14.24 seconds (16.86), -6.49 seconds (9.88), and -5.65 seconds (8.10). CONCLUSION: Results support the efficacy of a minimal dose task-oriented circuit training program with caregiver help to enhance locomotor recovery and walking competency in these persons with stroke.

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.
