AI for the human brain 

Our approach to artificial intelligence (AI) is tuned to the dynamic and delicate reality of the human brain. We believe that AI, when used for brain science, must be applied transparently, so that results are explainable and reproducible. We also believe in creating a level of accountability and clarity to demonstrate why an AI-based system recommends the actions it takes.

As each patient’s brain learns and grows, so does our AI. AI exposes patients, clinicians, institutions, and healthcare systems to new knowledge on a regular basis, thereby advancing the science of brain recovery in all of its depth and breadth.

Meet the NeuroPerformance Engine

Our patented NeuroPerformance Engine™ is the revolutionary AI at the core of Constant Therapy and all products created by The Learning Corp.

The NeuroPerformance Engine™ constantly monitors and analyzes the real world evidence generated by patient performance and progress. Through self-learning technology, it presents—and constantly adjusts—exercises based on patients’ past performance data, and on the performance data of thousands of other people with similar conditions.

Powered by the NeuroPerformance Engine™, Constant Therapy delivers personalized exercises to patients at the right time, appropriately calibrated to where they are in their therapy and recovery process. Because the NeuroPerformance Engine™ is self-learning and adaptive, its ability to deliver new exercises is limitless. Every 3.5 seconds, a patient completes an exercise, generating the real world evidence that teaches the program something new.

Thanks to the real-time, real world evidence collected by the NeuroPerformance Engine™The Learning Corp discovers ways to improve individual exercises, fine-tune the sequence of therapies, and update current protocols. And because the way in which data is collected rigorously conforms to best practices and existing standards of care, The Learning Corp can advance brain science by publishing and sharing our learnings. Illuminating more effective therapeutic approaches to clinicians, neurologists, and other scientists can help to bring better methods and results to patients all around the world.

Constant Therapy

Constant Therapy is an award-winning cognitive, language, and speech therapy app, powered by the NeuroPerformance Engine™.

By combining cutting-edge AI technology with real world evidence based research, Constant Therapy is advancing brain science and elevating the standard of brain rehabilitation.

Maximizing recovery potential

Constant Therapy delivers personalized, clinically proven therapy to those with brain injury and neurological and speech disorders. It includes exercises across 80 categories of cognitive, language, and speech therapy, and is designed for independent use or in conjunction with clinical therapy.

Constant Therapy can be used for patients with a range of conditions, including stroke, traumatic brain injury (TBI), and neurological disorders such as aphasia, dementia, and Alzheimer’s disease.

Real world evidence-based and clinically proven

  • All exercises in the Constant Therapy app are well established and clinically proven to improve brain function

Personalized and adaptive

  • The NeuroPerformance Engine™ constantly monitors and analyzes patient performance to optimize and individualize their exercises

Maintain clinical therapy after discharge 

  • With unlimited access, patients can maintain clinically proven therapy once in-clinic sessions are no longer covered by insurance
  • Standardizes care and reduces administrative burden

Real-time performance metrics and analytics

  • Providers can view real-time, quantitative performance metrics and analytics to fine-tune and improve the standard of care

Automated reporting and documentation

  • The Constant Therapy platform automates reporting and documentation from every level of care, across institutions: patients, clinicians, and facilities
  • Automated reports and documentation reduce a significant burden from providers, creating process efficiencies, consistencies, and cost savings

Improving access

Constant Therapy is the high-value, low-cost solution to improving access to therapy.

According to an analysis by CostHelper Health, the estimated national average cost of a single speech therapy session is between $100 to $250. For less than the cost of one session, a patient can access a full year of unlimited, on-demand access to personalized, clinically proven cognitive, language, and speech therapy.

Constant Therapy is the answer to maintaining clinical therapy after discharge, so patients can reach their recovery potential. It is simple to implement and available to anyone—putting hope for recovery into as many hands as possible.

New study signals benefits of Constant Therapy for stroke patients

A new study comparing home and clinic Constant Therapy users shows that home users took less time to master tasks than users who only practiced in the clinic, and home users practiced therapy more frequently than clinic users. See the study.
