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.
87% of participants reported improvement in quality of life.
Improvement was demonstrated in participants up to 34 years post-injury.

Discover The Potential Benefits

ARCEX is designed to help people with spinal cord injury regain more control over their day.

The system consists of an external Stimulator and electrodes designed specifically for people with SCI.

This is a example

Arm and hand movement

Dexterity and finger control


“When we talk about 10% more function, we think about how important that is in terms of being able to live a life. That little bit more independence allows you to do so much more.”

As of April, 2024, we have submitted a regulatory application to the US Food and Drug Administration (FDA) to allow marketing of our breakthrough ARCEX System to restore function of the upper extremities after spinal cord injury.
