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.
