Empowering Neurological Care: QA Innovations for Machine Medicine Technologies

Overview

Machine Medicine Technologies (MMT) is a healthtech company that uses AI-powered video analysis to assess and track motor function in patients with neurological conditions like Parkinson’s disease. Their platform, KELVIN™, supports remote and objective clinical evaluations used by specialists worldwide.

Project Goals

MMT required a QA process that could ensure high test      coverage for both mobile and web platforms, while also validating AI-powered motion tracking algorithms. The goal was to improve clinical reliability, ensure regulatory compliance (HIPAA), and stabilize the product for enterprise-level demos and hospital partnerships.

Challenges

The product faced serious stability and accuracy issues, which directly affected clinical use and slowed adoption:

  • Mobile app crashes during live sessions caused interruptions during patient assessments, reducing trust among healthcare providers
  • Syncing failures between mobile and web led to incomplete reports, affecting diagnostic quality
  • Functional inconsistencies made training difficult and led to high user frustration
  • Limited test coverage and manual-only QA increased production bugs and slowed release cycles

 

These issues made it harder to demonstrate the product confidently, impacted clinician retention, and created friction in acquiring new users.

Testiva’s Solutions

To address both the product and business risks, Testiva deployed a structured QA strategy that combined industry best practices with project-specific actions:

  • Introduced a risk-based test planning model focusing on high-priority clinical flows
  • Built sprint-aligned manual test cases to cover 95% of key features
  • Implemented end-to-end test automation using Playwright (web) and Appium (mobile)
  • Simulated real-world challenges like poor connectivity, session interruptions, and multi-device workflows
  • Integrated automated test runs into CI/CD to catch issues early and reduce manual effort
  • Logged and verified over 200 bugs, ensuring traceability and fast turnaround from dev teams

Results & Impact

Testiva’s efforts led to measurable improvements across product quality and business performance:

  • Functional test coverage reached 95%, enabling faster, safer releases
  • Production issues were reduced by 95%, improving reliability during clinical sessions
  • Application performance improved by 80%, leading to fewer drop-offs and shorter wait times
  • The platform met HIPAA compliance standards, boosting security and trust
  • Testiva supported five successful stakeholder demos, restoring confidence in the product
  • User retention increased by 60% after resolving high-impact UX and stability issues
