Objectives: To describe the clinical characteristics of persistent extension of the great toe related to overactivity of the extensor hallucis longus (EHL) after a stroke and to explore the efficacy of treatment with botulinum toxin type A.
Design: Case series.
Setting: A physical medicine and rehabilitation department in France.
Participants: Eleven patients with hemiplegia disabled by overactivity of the EHL were classified according to the different ways in which that overactivity was triggered. Disability was related to pain in 5 patients, to shoe difficulties in 10 patients, and to varus foot in 6 patients.
Intervention: Injection of botulinum toxin type A into the EHL.
Main Outcome Measures: Efficacy was assessed on day 15 by triggering of pain, shoe difficulties, and varus deformity and by patients' subjective assessment on day 15, at 3 months, and at 6 months.
Results: On day 15, EHL overactivity disappeared after 16 of the 18 injections in 10 patients; subjective assessment was very good for pain and shoe difficulties and remained good or very good at 3 months for 8 patients who received 12 injections.
Conclusion: Botulinum toxin type A is effective in treating disability related to poststroke overactivity of the EHL.

Botulinum toxin (BoNT) has traditionally been utilized to relieve tension in muscular and connective tissue diseases (CTD). However, its usage has rapidly expanded and now encompasses usage for neurological, gastrointestinal, psychological, cardiovascular, ophthalmology, orthopedics, and more. More recently, its usage has been utilized for sequelae of CTDs such as Raynaud's disease and reduced oral aperture secondary to scleroderma/systemic sclerosis.
