For millions of people living with Parkinson's disease, walking can feel like an impossible challenge. But a groundbreaking innovation from Mumbai is changing that narrative, offering renewed hope and independence to those struggling with gait freezing.

Lifespark Technologies, a health technology startup, has developed WALK, a revolutionary wearable device that helps Parkinson's patients overcome mobility challenges through cutting-edge sensory intervention. Co-founded by electrical engineer Amey Desai and Dr. Devendra Desai, the device addresses a critical need for India's estimated 7 million Parkinson's patients who experience debilitating movement difficulties.

The device's origin is deeply personal and scientific. Amey Desai's experience with his grandfather's Parkinson's, combined with his academic training in neural motor control, inspired a solution rooted in advanced neuromuscular physiology. Research shows that walking isn't just controlled by conscious brain signals, but also by spinal circuits and sensory feedback - a key insight that became WALK's fundamental design principle.

WALK is a sophisticated three-layer system combining a lower-limb wearable, mobile application, and cloud-based monitoring platform. The wearable uses accelerometers and gyroscopes to analyze walking patterns in real-time, detecting gait irregularities associated with freezing. When such patterns emerge, the device delivers gentle rhythmic vibrations and mild electrical stimulation, helping users restart coordinated movement.

The device underwent rigorous development, including prototype creation in 2021 and comprehensive medical certification. Lifespark obtained ISO 13485 certification and a manufacturing licence from the Central Drugs Standard Control Organisation, ensuring international quality standards. Clinical trials at the National Institute of Mental Health and Neurosciences validated the technology's safety and effectiveness.

Beyond the hardware, WALK offers a comprehensive support ecosystem. Its smartphone application allows patients to personalize therapy settings, monitor walking performance, and access guided physiotherapy exercises. The Pathfinder cloud platform enables clinicians to remotely track patient progress, review movement data, and continuously refine treatment protocols.

This innovative solution represents more than a technological breakthrough - it's a lifeline for individuals reclaiming their mobility and independence. By transforming scientific understanding into a practical, wearable intervention, Lifespark Technologies is helping Parkinson's patients walk with renewed confidence and dignity.
