The Challenge

A Growing Global Health Crisis

Parkinson's disease is the second most common neurodegenerative disorder, affecting millions worldwide. Freezing of Gait is one of its most debilitating and dangerous symptoms.

What is Freezing of Gait?

Freezing of Gait (FoG) is an episodic phenomenon where patients suddenly feel their feet are "glued" to the ground during walking. This debilitating symptom severely impacts mobility, independence, and quality of life.

Unpredictable Occurrence

Episodes occur without warning and are difficult to detect in clinical settings

Medication Resistance

Becomes less responsive to drug therapies as the disease progresses

High Fall Risk

Primary cause of fall-related injuries in Parkinson's patients

Clinical Progression of FoG

Our Solution

Intelligent Closed-Loop Intervention

FoGO continuously monitors gait patterns, detects freezing episodes in real-time, and delivers immediate therapeutic cueing—all without cloud connectivity.

Processing pipeline

Continuous Sensing

Bilateral ankle IMUs capture accelerometer and gyroscope data during all walking activities

Edge AI Detection

Optimized machine learning model processes data on-device to identify FoG signatures in real-time

Therapeutic Cueing

Chest-mounted vibrotactile module delivers immediate sensory stimulation to help resume walking

Adaptive Control System

Our proprietary control logic ensures precise timing of therapeutic intervention while preventing over-stimulation.

1
Monitor walking patterns continuously
2
Detect FoG onset using threshold + debounce logic
3
Activate vibrotactile cueing immediately
4
Verify recovery and enter cooldown state
