Sex eligibility reported by registry: -

Inclusion criteria: Diagnosis of idiopathic Parkinson's disease by a neurologist according to the criteria of the International Parkinson and Movement Disorders Society; Maintain stable treatment with dopaminergic medication, without planned changes in medication during the study; Be in stages I to III of the Hoehn & Yahr classification; Presence of classic parkinsonian tremor type 1 according to the consensus statement on tremor of the International Parkinson and Movement Disorders Society Exclusion criteria: Individuals with previously documented dementia or a score of 22 or lower on the Montreal Cognitive Assessment; Individuals with other associated neurological diseases, specifically those that also present with tremor, such as essential tremor and peripheral neuropathies; Individuals with mild to severe sensory impairments that make their response to sensory stimulation unpredictable, measured with a graduated tuning fork, will be excluded with an average score of 5.9 or lower on the wrist; Presence of dyskinesias; Deep brain stimulation implant, or other conditions that prevent participation in the study procedures.

Official study title

Wearable electronic device for tremor mitigation in Parkinson's disease: a feasibility study

Short title used by the registry

Wearable electronic device for reducing tremor in Parkinson's disease

Original description

Intervention: This is a randomized, double-blind, placebo-controlled, crossover clinical trial. It will involve 18 individuals of both sexes, aged 45 to 65 years, diagnosed with idiopathic Parkinson's disease (Hoehn & Yahr stages I to III) and presenting with classic type I tremor. Participants will undergo three intervention conditions: two vibration frequencies, high and low frequency, and a placebo condition (no vibration) applied to the forearm of the limb with the greatest tremor in each participant. The sessions will occur in a single session for each vibrational stimulation frequency, with their order randomized, and will also have a washout period of at least 48 hours between them, taking place during the off-period of dopaminergic medication Primary outcome: It is expected that participants will experience a greater reduction in the severity of Parkinsonian tremor when subjected to high-frequency vibration intervention compared to low-frequency vibration and placebo (no vibration) Secondary outcome: It is expected that individuals subjected to high-frequency vibration will show improved performance on manual dexterity tests such as the Nine Hole Peg Test and the Box and Block Test compared to those subjected to low-frequency vibration and placebo (no vibration)

Conditions reported: Parkinson Disease; Tremor Nervous System Diseases
