Empowered by Independence
People with spinal cord injury (SCI) will enjoy
life in the ways that matter to them.
ARC Therapy is targeted, programmed electrical stimulation of the spinal cord to restore movement, function, and independence in people with SCI.

Discover our Therapy

The ARCEX is indicated to improve hand sensation and strength for people with a chronic cervical spinal cord injury.
The system is comprised of a Stimulator that delivers electrical pulses to the cervical spinal cord via Electrodes placed on the skin at the back of the neck.
ARCEX can be used in the clinic to enable personalized functional rehabilitation.
The ARCEX System is now available for purchase. Fill out the form below to learn more.
Read The Evidence

The results from our Up-LIFT pivotal trial were published in Nature Medicine, one of the world’s preeminent scientific journals.
The Up-LIFT study evaluated the safety and effectiveness of non-invasive electrical spinal cord stimulation (ARCEX Therapy) to improve upper limb mobility in people with chronic incomplete tetraplegia. The clinical study enrolled 65 people at 14 leading SCI centers in the US, Europe, and Canada.
Highlights* include:
Primary safety and effectiveness endpoints met.
90% of participants improved strength or function of their upper limbs.
Upper extremity sensory scores improved significantly with device use.
87% of participants reported improvement in quality of life.
Improvement was demonstrated in participants up to 34 years post-injury.
ARC Therapy Evidence
We have a growing body of evidence for multiple indications across both our external and implantable technology platforms
