Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Building on these findings, the SPARKL clinical study aims to further this research. The SPARKL study aims to enroll six individuals with advanced Parkinson's Disease to assess the safety and efficacy of the novel ARC-IM Therapy. This new therapy has been designed to overcome previous technological limitations and facilitate its home-use.
This study will take place at the Lausanne University Hospital (CHUV, Switzerland). The total duration of the study is 4 years per participant. The study intervention consists of several phases preceded by pre-screening. The first year involves an intensive participation, consisting of the following phases: enrolment and baseline, surgical implantation of the stimulation device, a main study phase that includes stimulation configuration sessions and both in-clinic and at-home rehabilitation, and finally the home-use phase. This will be succeeded by 3 years of safety follow-up, during which the participant can use the stimulation device in their daily life, subject to investigator approval.
Throughout the study, the investigators will conduct assessments at various stages of each participant's journey in the study. These assessments will be used to assess the preliminary safety and efficacy of the ARC-IM therapy at alleviating locomotor deficits.

All participants
All participants enrolled in the study will receive the same intervention.
The first year of the study consists of the following phases: enrolment, baseline assessments, surgical implantation of the ARC-IM stimulation device, configuration sessions for stimulation, in-clinic and at-home rehabilitation, and a home-use phase. It is followed by 3 years of safety follow-up.
Assessments will be planned throughout the course of the study and at baseline, the end of the optimization phase, the end of the rehabilitation phase, and after 12 months post-surgery.
ARC-IM System implantation
