Brief Summary:
The HemON study aims to evaluate the safety and preliminary efficacy of ARC-IM Therapy (Epidural Electrical Stimulation) to improve hemodynamic management and trunk control in people with sub-acute or chronic spinal cord injury (>= 1 month post injury) between C3 and T6 inclusive, who suffer from orthostatic hypotension.

Arm Intervention/treatment
Experimental: all participants
All participants will be provided with the ARC-IM Investigational System (implantable and non-implantable parts)
 Device: ARC-IM Investigational System implantation
Implantation of a stimulation lead on the low thoracic level of the spinal cord and implantation of a neurostimulator in the abdominal region.


Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Occurrence of Serious Adverse Events and Adverse Events that are deemed related or possibly related to the study procedure or to the ARC-IM Investigational System [ Time Frame: Throughout study, an average of 26 months ]
    Evaluate the safety of ARC-IM Therapy at supporting management of hemodynamic instability in participants with sub-acute or chronic spinal cord injury suffering from orthostatic hypotension


Secondary Outcome Measures :
  1. Orthostatic head-up tilt test (hemodynamic stability assessment) [ Time Frame: Baseline ; at 1 - 6.5 - 13 - 19.5 - 26 months after the implantation ]
    Participant begin by resting in the supine position during which baseline measures are performed. Thereafter, participant is passively moved to upright position using a tilt-table and kept in this position for a maximum of 10 minutes. This test will be performed with and without ARC-IM Therapy. Beat by beat blood pressure is monitored and catecholamine concentrations in the plasma are measured during the tilt-test.

  2. Trunk stability measurement (trunk control assessment) [ Time Frame: Baseline ; at 1 - 6.5 - 13 - 19.5 - 26 months after the implantation ]
    The participant is asked to perform a systematic set of reaching movements, balance and posture tasks while seated freely (without a back-rest). Each task is repeated and pressure, force, kinetic and kinematic data is recorded together with video acquisitions.

  3. Modified Ashworth Scale (MAS) (spasticity assessment) [ Time Frame: Baseline ; at 1 - 6.5 - 13 - 19.5 - 26 months after the implantation ]

    Participants' upper and lower limb spasticity levels (6 points nominal scale) are assessed by rating the resistance of a muscle to a passive range of motion about a single joint. This test will be performed with and without ARC-IM Therapy.

    Scores range from 0 to 5 (0, 1, 1+, 2, 3, 4, 5) with higher scores indicating higher spasticity.


  4. SCIM III (daily life performance assessment) [ Time Frame: Baseline ; at 1 - 6.5 - 13 - 19.5 - 26 months after the implantation ]
    The Spinal Cord Independence Measure (SCIM) is a disability score to assess functional activity in participants. Function is assessed in 3 areas of function: self-care (0-20), respiration and sphincter management (0-40) and mobility (0-40). Total score ranges between 0-100, with higher scores reflecting greater functional ability
