It started with a pattern nurses saw every shift. Patients spending 90%+ of their hospital stay immobile in bed. Losing 2% of muscle mass daily. Leaving the hospital weaker than when they arrived. The harm was visible at the bedside.

Physical therapists felt the gap just as acutely. Real progress made in the morning. Gone the next day when a patient missed their session for a scan or a procedure. "We're stretched thin," they told the care team. "We need something that keeps patients moving between sessions."

As a physician with a computer science background, Dr. Neil Jairath knew the problem could be solved. He partnered with Brian Sabino, a mechatronics engineer, to build a solution that fits nurse and physical therapy workflows.

Eleven versions and years of real hospital feedback later, Spark™ combines recumbent upper and lower body strength sessions, cardiopulmonary engagement, AI-driven risk detection, and real-time dashboards into a single bedside system. Designed to support structured in-bed movement and present objective activity data, Spark™ supports mobility-related workflows, interdisciplinary communication, and discharge planning conversations alongside clinical judgment.
