A Brief History of the ALS Knowledge Base​

What's Next?

The Assistive Technology Clinic (ATC)

The Assistive Technology Clinic (ATC) was founded by Pearl Gryfe with the mission to combine innovative medical and neurological rehabilitation therapy programs with cutting-edge technologies for customized patient care. Pearl quickly started exploring ground breaking technologies and care programs to help people with complex neuromuscular disorders such as ALS, Parkinson's, CP, and MS. ATC grew rapidly in the Toronto area, and by 2020 was caring for more than 4,000 patients each year. 

1994 - 2020

COVID & Changes in Care

ATC held its breath as COVID gripped the world, knowing that their client population was most at risk from exposure and that its programs needed to change to continue providing essential care. In person visits were cancelled in favour of virtual care wherever possible and ATC took on major restructuring to accommodate the realities times. 

Although forced to downsize, new strategies were put in place to ensure that clients continued to receive the care they need. Through partnerships with innovative healthcare providers and new concepts in virtual care, ATC has worked hard to continue its legacy of caring for its clients with more limited resources.


The ALS Knowledge Base

ATC's new reality meant that its large multidisciplinary team would become fractured, along with the knowledge that it had built over decades of experience. The ALS Knowledge Base - a living repository of professional guides and tools for helping healthcare professionals care for their patients living with ALS - was conceived to ensure that ATC's unique expertise in caring for thousands of clients with ALS could continue to help other professionals in the community who are less familiar with the disease. 



ATC's experienced team worked hard to save and organize the knowledge and documents they had accumulated over the decades, and the ALS Knowledge Base was born. We're proud to present this resource with the ambition of continuing our support for the ALS community worldwide.


We use the ALS Knowledge Base for our own reference as we continue to explore opportunities to help our patients. We’ll continue to add and change the content as our knowledge increases or changes.
