Summary

This trial aims to study how electrical stimulation impacts proprioception and fine motor control in the arm. They will use different types of electrical stimulation and various assessments to measure the effects on healthy individuals and patients with

Who is the study for?

This trial is for adults aged 18-80 with essential tremor (ET) and healthy individuals without tremors. ET patients must have a moderate-severe wrist tremor, no skull lesions or history of significant head trauma, stable medication doses, and normal hearing/vision. Healthy participants need normal neurological function and cannot be pregnant or have a history of substance abuse.

What is being tested?

The study tests the effects of sensory electrical stimulation on proprioception (sense of body position) and motor control in people with ET and healthy controls. It involves non-invasive electrical stimulation strategies, muscle activity recording (HD-EMG), arm movement tracking, and clinical assessments.

What are the potential side effects?

Potential side effects may include discomfort at the stimulation site, skin irritation from electrodes, temporary changes in sensation or muscle twitching during electrical stimulation.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Transcutaneous asESExperimental Treatment2 Interventions

Participants will be administered transcutaneous afferent-specific electrical stimulation in the upper limb using conductive pads targeting the median and radial nerves at the wrist

Group II: Percutaneous asESExperimental Treatment2 Interventions

Participants will be administered percutaneous afferent-specific electrical stimulation in the upper limb using intramuscular leads targeting the flexor and extensor muscles of the wrist
