Implanted Peroneal Nerve Stimulator Treatment for Drop Foot Caused by Central Nervous System Lesion: A Twelve-Month Follow-up of 21 Patients
Bibliographic record
Abstract
Objective: Drop foot is a common impairment following stroke or other causes of central pathology. We report data on patient self-perceived performance, satisfaction with performance, walking ability, and adverse effects after surgical implantation of the ActiGait® drop foot stimulator.Design: Prospective case study with a 12-month follow-up.Subjects: Twenty-one participants with drop foot caused by central nervous system lesion.Methods: The patients’ self-perceived performance and satisfaction with performance were evaluated using the Canadian Occupational Performance Measure (COPM). Walking ability was assessed using a 10-m walk test and a 6-min walk. Nerve conduction of the peroneal nerve was examined in 10 patients.Results: At follow-up, COPM self-percieved performance from 3.2 to 6.7 points, the median increase being 2.8 (interquartile range (IQR) 2.2–5.0), p < 0.001. Likewise, the COPM satisfaction with performance increased from 2.6 to 6.9 points, the median increase being 4.2 (IQR 2.8–5.8), p < 0.001. Walking velocity increased 0.1 m/s from a baseline measurement of 0.73 m/s (95% confidence interval (95% CI) 0.03–0.2), n = 21, p < 0.01, and walking distance increased by 33 m, from a baseline measurement of 236 m (95% CI 15–51), n = 21, p < 0.001.Conclusion: Stimulation of the peroneal nerve by an implantable stimulator increases self-perceived performance, satisfaction with performance, and ambulation in patients with long-lasting drop foot caused by a central nervous system lesion. LAY ABSTRACTDrop foot is a common impairment following stroke or other causes of disease in the nervous system. This study of 21 patients with drop foot caused by various diseases in the central nervous system reports data on patient self-perceived performance, satisfaction with performance, walking ability, and adverse effects after surgical implantation of the ActiGait® peroneal nerve stimulator. The patients’ self-perceived performance and satisfaction with performance were evaluated using the Canadian Occupational Performance Measure. Walking ability was assessed using a 10-m walk test and a 6-min walk test before implantation and at follow-up. At follow-up, patient self-perceived performance, satisfaction with performance, walking velocity, and walking distance increased. No changes in nerve function were demonstrated. In conclusion, implantable peroneal nerve stimulation increases self-perceived performance, satisfaction with performance, and ambulation in patients with long-lasting drop foot caused by central nervous system lesion.

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.
