Sarcolink was founded in 2025 following the pioneering development of our Class 1.0 EMG Biofeedback System. This innovative technology harnesses modern computing, sophisticated sensors, and statistical models to enhance therapeutic exercise. Our mission is to leverage our cutting-edge rehabilitation system to increase the opportunity for people living with challenging physical disabilities to rebuild their functional capacity, reclaim their independence, and maintain a good quality of life.
From Isolated Movements to Integrated Motion!
The Sarcolink Program represents the next generation of biofeedback technology, enabling therapists to integrate three or more movements into a single, cohesive training experience. This approach supports more dynamic, functional, and adaptable rehabilitation exercises.
Designed to enhance interventions targeting strength, coordination, and balance, the Sarcolink Program is well-suited for a range of complex rehabilitation needs, including:
Hip or lower limb fracture
Hip or knee arthroplasty
Multiple sclerosis
Parkinson’s disease
Stroke
The Sarcolink Program
Assessment:
Session 1:
In-depth interview and movement assessment to understand your individual needs and goals.
Personalization:
Program Design:
Data from your assessment is analyzed to build a program tailored to your individual needs and goals.
3. Program Execution:
Sessions 2-19:
A trained Sarcolink technician works 1-1 with you for 18 sessions following your personalized training program.
Session 20:
Repeat the movement assessment to evaluate your progress and determine next steps.
Training in Action
The biofeedback user executes therapist-designed movements to alter the position and orientation of falling puzzle pieces in the classic Tetris arcade game.
In the video below, Class 1.0 is configured to enable the user to practice shifting their weight from side-to-side while the hands are also occupied. This simulates everyday activities, like cooking, cleaning and laundry.
On the bottom right of the video, Class 1.0 counts and displays the number of times that each movement is performed within the biofeedback session. In a 30-minute session, the user will perform between 100 and 200 repetitions of each movement prescribed by the therapist. This provides useful information about the exercise dose to the therapist, and is a source of motivating positive reinforcement to the user.
On-Site Location:
We are currently located at Gateway Neurophysio. Participants will arrive at our facility for their Sarcolink Program sessions and assessments.
150 Chatham St unit 7, Hamilton, ON L8P 2B6
At-Home Visits:
We currently offer at-home sessions for participants unable to commute and reasonably distant from our main facility. If you are interested in opting for at-home Sarcolink Program sessions, please get in touch with us, and we’d be happy to make the arrangements.

Research
Multiclass EMG Biofeedback is an emerging technology and thus the subject of ongoing scientific research. We will continue to maintain an inclusive list of scholarly manuscripts that are published on this topic.
