New study aims to objectively measure internal tremors in Parkinson's patients
NCT ID NCT06885541
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses small motion sensors to detect internal tremors—a common but hard-to-measure symptom—in people with Parkinson's disease. Researchers will compare 60 participants (30 with Parkinson's and 30 healthy volunteers) to see if a specific 4-6 Hz rhythm can be identified. The goal is to better understand and objectively measure this symptom, not to test a treatment.

Inclusion Criteria: (For the experimental group) * Patient with idiopathic parkinson's disease * Mini Mental State Evaluation score above or equal to 25 * Hoehn and Yahr scale score of ≤3 in the OFF phase, with postural stability allowing the patient to stand unaided for 1 minute. * Able to walk unassisted * Willing to undergo accelerometry in the OFF state (For the control group) * Healthy volunteer subjects matched for age (+/- 5 years) and sex * Mini Mental State Evaluation score above or equal to 25 Exclusion Criteria: (For the experimental group) * Patients with an atypical parkinsonian syndrome * Patients unable to walk or stand for more than one minute in the off state * Parkinson's patients treated with deep brain stimulation, apomorphine pump, or duodopa intestinal infusion, and foslevodopa * Pregnant patients * Major osteoarticular problems * Neurological condition that may affect gait (For the control group) * Participants with significant gait impairment (osteoarticular disorder) * Those with a neurological disease that, in the investigator's judgment, may interfere with the study's outcome measure * Participants with a clinical tremor that may interfere with the measurement of the primary outcome (e.g., essential tremor, thyroid disease, or tremors induced by medication) * Pregnant participants
