PhysioGrow: AI-Powered Physical Therapy Form Correction

Inspiration

Poor form during rehabilitation can lead to injury or ineffective treatment, and at-home sessions often lack feedback and motivation. PhysioGrow is a web application that uses real-time computer vision and AI to analyze and correct exercise form while keeping people engaged through visual progress tracking and immediate feedback.

What it does

Analyzes exercise form in real time using pose estimation
Provides instant audio and visual cues to correct technique
Ties progress to a garden where a tree grows with consistent, high-quality sessions
Rewards good form with XP, streak multipliers, and achievements

How it works

Core functionality: form analysis and correction

Uses Google MediaPipe for real-time AI computer vision pose detection and analysis
Tracks 33 body landmarks to produce precise skeletal data for form evaluation

Exercise form analysis

Shoulder Abduction: analyzes elbow, wrist, and shoulder angles
Knee Bends: tracks knee alignment, hip stability, and depth
Arm Circles: monitors shoulder position and arm trajectory
Compares real-time data to optimal parameters and flags deviations for correction

Real-time feedback system

Audio cues: “Bend your knees more” and “Keep your back straight”
Visual indicators: color-coded feedback (green = good, yellow = warning, red = poor)
Form correction suggestions: specific, actionable instructions

Gamification integration

Perfect-form sessions earn bonus XP and streak multipliers
Consistently good form accelerates tree growth in the garden
Measurable improvement over time unlocks special achievements

Innovation

Precise form analysis

Uses MediaPipe’s pose estimation for physical therapy specific analysis. The system understands rehabilitation biomechanics and gives targeted feedback.

Real-time correction

Not just tracking. The app actively corrects form in the moment to help prevent injury and improve effectiveness.

Accessibility through TTS

All feedback is delivered through text to speech for hands-free exercise and better accessibility.

Gamified motivation

A floating island garden provides visual motivation, and rewards are tied to form quality so users focus on proper technique rather than just finishing reps.
