A new clinical study published in the peer-reviewed Journal of Medical Internet Research demonstrates that the computer vision technology from Kaia Health is as accurate as a physical therapist in suggesting exercise corrections, according to a media release from Kaia Health.

The digital musculoskeletal (MSK) platform is already included in the Kaia Health product and complements its US network of physical therapists.

In the study, patients with osteoarthritis of the knee or hip performed a series of exercises while being simultaneously evaluated by computer vision technology and physical therapists. The results suggest that physical therapists agreed as much with the exercise corrections suggested by Kaia Health computer vision technology as they did with one another’s exercise corrections.

Provides Real-Time Feedback

Kaia Health computer vision technology, formerly known as Motion Coach, provides automated, real-time exercise feedback by tracking exercise form through the user’s smartphone camera. This proprietary technology makes it possible to provide users with exercise guidance during every exercise session.

“By integrating computer vision technology with our network of physical therapists, Kaia Health is changing the MSK care paradigm. By combining world-class technology and human intervention, Kaia Health offers a complete continuum of MSK care for users.”

— Kaia Health US Chief Medical Officer Justin Yang, MD

The New York– and Munich-based digital therapeutics company recently announced a $75 million Series C round ($125 million raised to date) to expand clinical capabilities, heavily invest in computer vision technology, and transform the treatment pathways for MSK in the U.S. and Europe.

The company’s AI-assisted therapy is unique in the MSK market and has been clinically validated for its accuracy. Additionally, Kaia Health features computer vision–based digital biomarkers such as a Toe-Touch Test to measure flexibility.

“The technology requires no additional hardware or sensors and instead leverages the camera on users’ own mobile devices. This enables a more engaging experience for our users—accessible at any time and anywhere. By combining our US network of physical therapists and coaches with this superior technology, we are defining what next-generation MSK care looks like.”

— Kaia Health Chief Revenue Officer CJ Mark

Kaia Health recently unveiled Kaia Gateway & Premium Partners, the next-generation complete MSK care solution for all US employers and health plans, based on a large randomized controlled trial. This trial demonstrated how an MSK care pathway combining digital therapy, personalized health coaching, and collaboration with medical providers achieved better outcomes than the standard of care.

About the Clinical Study

Twenty-four participants were enrolled and performed the assessments so that a dataset of 552 exercise sets was evaluated in the study. The interrater agreements showed an accuracy of r=0.828 (computer vision vs. physical therapist) vs. r=0.833 (physical therapist 1 vs. physical therapist 2), p<0.001, and confirmed non-inferiority of the computer vision corrections to a physical therapist’s corrections.

Subgroup analysis based on age with a split of 70 years or under, gender, and body mass index with a split of 30 or under, revealed no detectable difference in interrater agreement in any subgroup. There was also no detectable difference in levels of interrater agreement between computer vision vs. physical therapist and physical therapists themselves in any of the exercises, regardless of exercise pose or difficulty level.
