Multi-Modal Sensing Enabled Closed-Loop Transcutaneous Vagal Nerve Stimulation for Musculoskeletal Injury and Disorders

Project: Research project

Project Details


The Etemadi Research Group will be responsible for 1) design, prototyping, and building of the wearable knee brace system and 2) clinical pilot study in Phase 2 on post-surgical patients. A summary by area is as follows:
1. Wearable design, prototyping, and building. A total of 90 manufactured devices will be produced for the phase 1 and 2 studies. Included in the budget is for 3 prototype runs to prepare for manufacturing runs of the devices.
2. Clinical pilot study. Two groups of patients will be recruited – those presenting for knee arthroscopic surgical repair of the medial meniscus, and those presenting for ACL tendon repair. Approximately 30 patients in each group will be recruited in the pre-op area by the anesthesiology service. Wearable measurements will be taken pre- and post-op as well as at home following their operation, during rehabilitation. For the meniscus patients, the approximate length of the study will be 2-3 weeks. For the ACL patients, approximately 6-8 weeks. Approximately half of each patient group (around 15 patients per group) will be instructed to use the transcutaneous vagal nerve stimulator.
