Are you currently receiving treatment(s) for tremor? The Wearable Biomechatronics Laboratory from the University of Western Ontario invites you to participate a survey study focusing on the current state of parkinsonian tremor management. Briefly, the study requires you to complete a questionnaire that collects information regarding the current state of parkinsonian tremor management. The questionnaire constitutes multiple selections and short answers. We expect that the questionnaire can be completed in less than 10 minutes.
