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.

* Able to understand and interact with the study team in French or English
* Agrees to comply in good faith with all conditions of the study and to attend all scheduled appointments

Exclusion Criteria:

* SCI related to a neurodegenerative disease
* Diseases and conditions that would increase the morbidity and mortality of spinal cord injury surgery
* The inability to withhold antiplatelet/anticoagulation agents perioperatively
* History of myocardial infarction or cerebrovascular event within the past 6 months
* Other conditions that would make the subject unable to participate in testing in the judgement of the investigators
* Clinically significant mental illness in the judgement of the investigators
* Botulinum toxin vesical and non-vesical injections in the previous 3 months before the enrolment
* Presence of significant pressure ulcers
* Recurrent urinary tract infection refractory to antibiotics
* Presence of indwelling baclofen or insulin pump
* Women who are pregnant (pregnancy test obligatory for woman of childbearing potential) or breast feeding,
* Lack of safe contraception for women of childbearing capacity,
* Intention to become pregnant during the course of the study,
* Other clinically significant concomitant disease states (e.g., renal failure, hepatic dysfunction, cardiovascular disease, etc.),
* Inability to follow the procedures of the study, e.g. due to language problems, psychological disorders or dementia of the participant,
* Participation in another study with investigational drug within the 30 days preceding and during the present study,
* Enrolment of the investigator, his/her family members, employees, and other dependent persons.
