The Effect of the STIL Orthosis on Action Tremor Severity in People With Parkinson's Disease
Parkinson's disease is a neurodegenerative condition that leads to uncontrollable shaking (tremor), which can substantially impair everyday activities. The goal of this clinical trial is to learn if the STIL Orthosis works as a treatment option for tremor in people with Parkinson's disease. The main questions it aims to answer are: * Does the STIL Orthosis reduce tremor? * Are users satisfied with the usability and comfort of the STIL Orthosis? * Does the STIL Orthosis have any adverse effects? Participants' tremor will be measured during three conditions: * While wearing the STIL Orthosis * While wearing an orthosis without dampening (sham) * While wearing no orthosis (baseline) Researchers will compare the severity of tremor while wearing the STIL Orthosis against tremor during sham and baseline.
• Participant is at least 18 years of age.
• Willing to sign the informed consent.
• Diagnosed with Parkinson's disease by a neurologist or movement disorders specialist.
• Action tremor in one or two arms (clinical severity score of at least 2 on their dominant side, on MDS-UPDRS items 3.15 or 3.16).
• At least experiencing wrist flexion/extension or forearm pronation/supination tremor.
