Foot Dystonia Treatment by Botulinum Toxin Injections in Parkinson Disease : Efficiency of Injections Made in Extrinsic Muscle (Flexor Digitorum Longus Muscle) Compared to Intrinsic Muscle (Flexor Digitorum Brevis or Quadratus Plantae Muscles)

Summary

Foot dystonia is frequently observed in patients suffering from Parkinson'disease. It is characterized by an abnormal involuntary movement which is very uncomfortable (difficult to walk) and painful for the patient. Botulinum toxin injections seem to be efficient to treat this dystonia. However studies on this topic are few and very imprecise (many muscle injected, especially the Flexor digitorum longus, different doses used, heterogeneous population with many types of dystonia included, open studies).
