Engineer Nishant Jain developed a wearable device to help his grandfather manage freezing of gait, a common symptom of Parkinson's disease where patients temporarily feel unable to move their feet.
The device provides rhythmic sensory cues, such as vibrations or auditory signals, which research shows can help the brain bypass impaired neural pathways and initiate movement.
After testing prototypes with his grandfather, Jain refined the design for comfort and ease of use, focusing on a wearable form factor that patients could manage independently.
The device is now being manufactured and distributed in India, where it is being used by Parkinson's patients in multiple cities.
Clinical validation studies are underway to quantify the device's effectiveness across different disease stages and patient profiles.
Jain has stated that the goal is to make the technology affordable and accessible, particularly in regions where specialized neurological care is limited.
The project illustrates how personal caregiving experience can translate into scalable assistive technology for neurodegenerative conditions.
Researchers note that while cueing strategies are well-established in rehabilitation literature, wearable implementations that are practical for daily home use remain an area of active development.
