Abstract
INTRODUCTION: Spasticity is a significant problem following stroke. Although there is extensive research examining the efficacy of botulinum toxin as a treatment, there are challenges in implementing its use. METHODS: The results from previously published randomized controlled trials and systematic reviews examining the use of botulinum toxin as a treatment for poststroke spasticity of the upper and lower limb and the shoulder are summarized. Several barriers to implementation are discussed. RESULTS: There is strong evidence that denervation of muscles, in the lower extremity and upper extremity post stroke, with botulinum toxin reduces focal spasticity. There is also strong evidence that it is associated with a small but significant improvement in gait velocity based on a recent meta-analysis. However, evidence that botulinum toxin injections are associated with improved function and improved quality of life is not as compelling. There is evidence that botulinum toxin injected into the subscapularis muscle can reduce spastic shoulder pain and improve passive range of motion of the hemiplegic shoulder. There are a number of challenges with botulinum toxin, including uncertainty over its role in improving motor dysfunction following stroke, the determination of which subsets of patients may benefit, the cost of treatment, and the identification of meaningful outcome measures. CONCLUSIONS: Botulinum toxin has been shown to be an effective treatment in reducing tone and managing spasticity post stroke. However, its effectiveness in improving function has been more controversial.

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 it
