Rationale Behind the Solution
Selection of Machine Learning Algorithms
SkuzaAI conducted a thorough analysis of various algorithms, selecting those best suited for processing gait and balance metrics. The decision-making process involved comparative experiments to identify the most effective algorithm for therapeutic recommendations.
Key Steps in the Process
Iterative Development Process
The model development was iterative, starting with detailed criteria for gait and balance metrics (e.g., number of steps, heel strike, step length, cadence). Each iteration involved data collection, preprocessing, feature extraction, and evaluation to refine the model continuously.
Definition of Gait and Balance Metrics
Metrics such as number of steps, heel strike, step length, cadence, stride time, symmetry, variability, and gait speed were selected for model evaluation and API integration.
Correlation of Metrics with Sound
A correlation analysis between gait/balance metrics and sound was conducted to identify musical features enhancing motor function. This involved selecting analysis methods, correlating tests, and choosing musical features.
Designing Requirements for ML Model
The focus was on selecting a suitable machine learning algorithm, conducting comparative experiments, and designing a dedicated algorithm for treatment recommendation based on specific metrics.
Model Training Process
Once the algorithm was selected, the model was trained on a representative dataset. This involved data preparation, model training based on stages like data collection, preprocessing, feature extraction, and evaluation.
API Design
Designing an API to exchange information between the model and medical devices. This involved defining requirements, architecture, development, testing, and ensuring security, privacy, compliance, and usability.
Results and Impact
Designed System Architecture
The system architecture integrated real-time data processing with adaptive machine learning models, enabling personalized treatment plans. This holistic approach enhanced motor function outcomes and streamlined clinical workflows.
Defined Datapoints Required for AI
These variables were critical in tailoring recommendations and improving predictive accuracy.
Selecting AI Models
Careful evaluation of several AI models was conducted, prioritizing those with strong performance in pattern recognition and adaptability to diverse patient data. This selection ensured robustness and reliability in clinical applications.
ROI and Costs Preparation
Comprehensive ROI analysis highlighted cost savings through reduced hospital readmissions and optimized therapy sessions. Budget planning accounted for development expenses while projecting long-term financial benefits and scalability.
Personalized Therapies Design
Personalized therapies templates were crafted using insights from patient-specific data, allowing customization that addresses individual needs and accelerates recovery.
Selection of Indicators to Monitor
Key Indicators and Monitoring Process
We also developed key indicators the healthcare company should monitor, involving the training of a machine learning model, integration of SoundSteps™ with medical-grade devices, data collection from users and devices, and iterative model refinement. These indicators include:
