THE SHORT READ

The Food and Drug Administration (FDA) approved an investigational device exemption for NeuWire Medical's STROKE-REWIRE trial of a wireless vagus nerve stimulator paired with arm rehabilitation after stroke, the company said. A feasibility study in the American Journal of Occupational Therapy tested occupational therapy with fully immersive virtual reality and debriefing for chronic pain.

    FDA approves investigational device exemption for pivotal trial of NeuWire's wireless vagus nerve stimulator for arm recovery
    The Food and Drug Administration (FDA) approved NeuWire Medical's investigational device exemption for STROKE-REWIRE, a prospective, multicenter, randomized, sham-controlled study of its ReWire Vagus Nerve Stimulation System in chronic ischemic stroke and upper-limb dysfunction, the company said Oct. 5. The wireless, battery-free implant uses closed-loop technology to pair stimulation with successful rehabilitation movements. The trial plans to enroll up to 135 participants at up to 12 U.S. sites, with change in Fugl-Meyer Assessment upper extremity score after 18 in-clinic sessions as the primary end point. The company said study initiation is expected in the first half of 2027.

    Immersive VR with debriefing is feasible for chronic pain in occupational therapy, but physical function favors standard care
    Researchers at Tufts University and the University of Pittsburgh randomized adults with chronic pain at an outpatient interdisciplinary pain clinic to standard occupational therapy or to occupational therapy integrating fully immersive virtual reality with debriefing; 31 enrolled and 16 had data suitable for analysis, according to a study published online Oct. 9 in the American Journal of Occupational Therapy. The virtual reality group improved in pain self-efficacy, fatigue and pain interference but declined in physical function, and between-group comparisons for physical function and social role participation favored standard care. The authors said the approach is feasible and engaging.
