Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
PostureGuard: Real-Time Exercise Form Classifier
BeginnerBuild a webcam-based application using MediaPipe Pose that captures a user performing rehab exercises (wall slides, clamshells, bridges) and provides real-time visual feedback on form quality. Classify movements as correct, mild compensation, or significant compensation based on joint angle thresholds.
RehabBot: LLM-Powered Home Exercise Guide
IntermediateCreate a conversational chatbot using LangChain and OpenAI that guides patients through a prescribed home exercise program. The bot answers questions about exercise technique, adapts instructions based on reported pain levels, and escalates to a human therapist when red-flag symptoms are detected.
MotionTrend: Wearable Sensor Movement Analytics Dashboard
IntermediateDevelop a dashboard that ingests IMU data from consumer wearables (e.g., MetaMotionR, Apple Watch), computes gait parameters (cadence, symmetry, step length), and visualizes recovery trends over a rehab episode. Include anomaly detection for sudden deterioration patterns.
AdaptRx: Contextual Bandit for Adaptive Exercise Prescription
AdvancedBuild a contextual bandit system that recommends exercise parameters (type, sets, reps, resistance) based on a simulated patient's session history, pain reports, and progress metrics. Compare the bandit strategy against a fixed protocol using simulated patient trajectories.
CliniNoteExtractor: Clinical NLP Pipeline for Therapy Notes
IntermediateFine-tune a HuggingFace transformer model to extract structured rehab entities (body region, diagnosis, intervention, outcome measure score, pain level) from de-identified physical therapy notes. Build an evaluation pipeline comparing model extractions against clinician annotations.
RehabSim: Biomechanical Simulation for Synthetic Movement Data
AdvancedUse OpenSim to create musculoskeletal simulations of common rehab exercises with parameterized compensatory movements. Generate a synthetic dataset of normal and compensatory movement patterns, export as simulated marker/IMU data, and use it to train a movement classifier that transfers to real clinical data.
PT-Validator: Clinical Validation Study Design and Analysis Toolkit
AdvancedDesign a complete clinical validation study protocol for an AI movement-assessment tool, including IRB-ready documentation, statistical analysis scripts (power calculation, Bland-Altman plots, sensitivity/specificity analysis, MCID interpretation), and a reporting template aligned with STARD-AI guidelines.
MultiModalRehab: Fusion Model Combining Video, Wearables, and PROMs
AdvancedBuild a multi-modal deep learning model that fuses pose-estimation keypoints from video, IMU time-series from a wrist-worn sensor, and weekly patient-reported outcome scores to produce a comprehensive rehab progress score. Implement attention-based fusion and evaluate against single-modality baselines.
