What this trial is about
This study investigates the long-term safety and tolerability of home peroneal eTNM® therapy using the URIS I™ device in subjects with Parkinson's disease (PD) or Essential Tremor (ET). Previously, a 6-week open-label pilot study with 24 PD or ET patients demonstrated that home-based peroneal eTNM® is safe, well-tolerated, and has a high adherence rate of over 90%. No treatment-related adverse events were observed. Although the pilot study was not designed to prove efficacy, it suggested positive effects on tremor, with improvements sustained for weeks after treatment. This extension study aims to further evaluate the long-term safety, tolerability, and efficacy of peroneal eTNM® in PD and ET patients.

- Hand/arm exhibiting tremor (resting and/or intentional and/or postural) ≥ grade 1 as assessed by the MDS-UPDRS tremor score in "on" period
- For subjects with ET:
- Visible hand/arm and/or foot/leg tremor (resting and/or intentional and/or postural) ≥ grade 1 as assessed by the TETRAS
Exclusion criteria
- Implanted electrical medical device, such as a pacemaker, defibrillator, or deep brain stimulator
- Suspected or diagnosed epilepsy or other seizure disorder
