Movement Disorder Quantification Algorithm Development

The purpose of this study is to collect kinematic motion data from subjects with movement disorders such as Parkinson's disease (PD) and essential tremor (ET) to develop and validate algorithms for quantifying motor symptoms such as tremor, bradykinesia (slowed movements), dyskinesias (sudden, involuntary movements), gait, and balance during standardized tasks and/or activities of daily living.

Inclusion Criteria:

• Aged 18 years or older
• Clinical diagnosis of idiopathic Parkinson's disease or essential tremor
• Able to provide informed consent

Exclusion Criteria:

• Significant medical or psychiatric illness
• Not capable of following the required clinical instructions
• Serious medical conditions that compromise safety
