Subjects will mark each item on this 30-item questionnaire on a scale ranging from 0-4 (0 being never and 4 being always). Points for each subscale are tallied and a total composite score is also given. A total score of 0-11 is considered normal, 12-28 is considered mild minimal handicap, 29-56 is considered moderate handicap, and 57-120 is considered severe handicap. | Baseline and up to 1 year |
| Efficacy rate based on global assessment of efficacy | The efficacy rate is the number of subjects assessed as "effective" based on the course of subjective symptoms and clinical symptoms during the observation period from the date of the first administration of BOTOX injections. | Up to 1 year |
