STIMO is a First-in-Man (FIM) study to confirm the safety and feasibility of a closed-loop Epidural Electrical Stimulation (EES) in combination with overground robot assisted rehabilitation training for patients with chronic incomplete spinal cord injury (SCI).
Patients will participate during 9-11 months, during which there will be
- Pre-implant evaluations (6-8 weeks)
- Device implantation and stimulation optimization (6-8 weeks)
- Overground rehabilitation training with EES (5-6 months) In the period after implantation, participants need to be present for testing and training, 4 days per week at the CHUV University Hospital in Lausanne (lodging can be provided).
At the end of the protocol, the study aims to make the patients walk better and faster, however, as this is the first study of its kind, success is not guaranteed.
STIMO is a First-in-Man (FIM) study with the objective to confirm the safety and feasibility of a closed-loop Epidural Electrical Stimulation (EES) in combination with overground robot assisted rehabilitation training for patients with chronic incomplete spinal cord injury (SCI), as it was previously demonstrated successfully in animals.
The study lasts about 9-11 months for each individual participant, from signing informed consent to the final test in the study. The period can be divided in 3 distinct phases:
- Pre-implant: about 6-8 weeks from informed consent to implant. During this phase, patient will participate during a total of 6 distinct days of evaluations, of which 5 days in Lausanne and 1 day at the assessment center in Zurich.
- Implant and stimulation optimization: about 6-8 weeks, including the implantation of the epidural lead and the neurostimulator. In this phase, the optimal stimulation parameters will be determined for the flexing and stretching of both legs.
During this period, participants need to be present 4-5 days per week at the CHUV University Hospital in Lausanne (lodging can be provided).
• Rehabilitation training and final evaluation: 4 days per week of rehabilitation training during a period of 5 months, followed by a final evaluation lasting 4 days in Lausanne and 1 day in Zurich. In this phase, the patients receive intensive overground rehabilitation training using a body weight support device in combination with EES, with the aim of improving the walking capabilities of the patient significantly.
During this period, participants need to be present 4 days per week at the CHUV University Hospital in Lausanne (lodging can be provided).
At the end of the protocol, the study aims to make the patients walk better and faster, as is quantified through the pre-defined measures which are assessed prior to implant and at the end of the study.
As this is the first study of its kind, success is not guaranteed, but the potential benefits outweigh over the potential risks.

Repair of the damaged neuron function after SPINAL CORD INJURY or SPINAL CORD DISEASES.
A syndrome associated with traumatic injury to the cervical or upper thoracic regions of the spinal cord characterized by weakness in the arms with relative sparing of the legs and variable sensory loss. This condition is associated with ischemia, hemorrhage, or necrosis involving the central portions of the spinal cord. Corticospinal fibers destined for the legs are spared due to their more external location in the spinal cord. This clinical pattern may emerge during recovery from spinal shock. Deficits may be transient or permanent.
Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.
Reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries. This condition may be associated with ARTERIOSCLEROSIS, trauma, emboli, diseases of the aorta, and other disorders. Prolonged ischemia may lead to INFARCTION of spinal cord tissue.
Ischemia or infarction of the spinal cord in the distribution of the anterior spinal artery, which supplies the ventral two-thirds of the spinal cord. This condition is usually associated with ATHEROSCLEROSIS of the aorta and may result from dissection of an AORTIC ANEURYSM or rarely dissection of the anterior spinal artery. Clinical features include weakness and loss of pain and temperature sensation below the level of injury, with relative sparing of position and vibratory sensation.

Spinal Cord Disorders
The spinal cord is a bundle of nerves that runs down the middle of the back which carry signals back and forth between the body and brain. It is protected by vertebrae, which are the bone disks that make up the spine. An accident that damages the verte...
