Difference of Foot Posture in Two Cases of Exercise-Induced Foot Dystonia

In most foot dystonias, the foot is usually plantar flexed and inverted [2] . However, the two cases of action-induced foot dystonia we present involve one patient who’s foot was plantar flexed with downward curling of toes, whereas the other patient’s foot was dorsiflexed and everted. Difference in foot posture in these two cases not only indicates diversity of abnormal postures which is not uncommon even in dystonia of other body parts but also highlights the complexity of neural mechanisms involved in dystonia. If a patient were to get treatment with botulinum toxin, careful assessment of abnormal posture of affected body parts becomes a very important factor in deciding which muscles should be injected.
