About Peter

What is Parkinson's Disease?

Parkinson's is a diverse neurological condition with over 40 known symptoms, affecting more than 10 million people globally. In the UK alone, 1 in 37 people will be diagnosed with Parkinson's in their lifetime.

What is Freezing of Gait?

Freezing of Gait (FoG) is a common and deeply frustrating symptom of Parkinson's disease. It's a sudden, involuntary inability to move your feet, despite the intention to walk. This sensation often happens without warning when turning, navigating doorways, or feeling stressed.

The consequences are severe. FoG is a primary cause of debilitating falls, leading to a loss of independence, repeat hospital visits, and an erosion of confidence. This fear often contributes to social isolation and a reduced quality of life.

Our Solution

Research shows that external sensory cues, like rhythmic sounds, can help the brain bypass the neural blockages that cause freezing. This can help people with Parkinson's initiate and maintain smoother walking.

Peter is a discreet wearable device that uses this cueing to alleviate freezing of gait. Peter uses bone conduction technology to deliver discreet, custom auditory prompts through vibrations sent directly to the inner ear via the bones of the skull. This means the cues are only audible to the wearer, enabling use in public without drawing attention.

By combining scientific insights with unobtrusive technology, Peter aims to support mobility, restore confidence, and reduce the risk of falls for people living with Parkinson's.

About the Team

Peter was founded by Jonathan Fisher, whose own father, Peter, suffered from freezing of gait. During his undergraduate studies at Brunel University of London, Jonathan designed the initial device, and after completing his master's degree at the University of Cambridge, he decided to make this technology available to everyone.
