次要结局
- 1. The effect of botulinum toxin: a. on resting tremor will be measured by: i. The change score on the CGI-C (Clinician Global Impression-Change) investigator scale, at six weeks post-injection; ° The delta of the severity scores on the CGI-S (Clinician Global Impression-Severity) investigator scale between injection and six weeks post-injection; ° The delta of the score of item 3.17 (amplitude) on the MDS-UPDRS III investigator scale between injection and six weeks post-injection; ii. The de
- The effect of botulinum toxin on the patient's experience will be measured by: a. The delta of the patient's quality of life score on the PDQ-39 self-questionnaire between the injection and six weeks post-injection b. The delta of the activities of daily living score using the MDS-UPDRS part two scale between injection and six weeks post-injection
- Safety of use will be measured by: a. The delta of the measurement in Newtons of the manual dynamometer, for the treated hand, between the injection and six weeks post-injection The delta of the scores for severity of muscle weakness in the treated hand, using the PGI-S scale (Patient Global Impression-Severity) completed by the patient between the injection and six weeks post-injection Collection of adverse events throughout the duration of the study
