Founder Focus: How An Injury Led To A Business Idea

By Abigail Bassett, Sunstone Staff Writer 

Joseph Rapaport has always been an athlete. A severe back injury in 2017 posed a significant question: surgery or physical therapy? Choosing the latter, Rapaport embarked on a journey that led to a business idea — the concept for Kenko Physical Therapy.

Rapaport’s choice to avoid surgery and give physical therapy (PT) a shot became one of the handful of catalysts that led him and his business partner, Allen Song (whom Rapaport later met in graduate school), to create Kenko Physical Therapy in 2022. It is a comprehensive, patient-focused exercise prescription platform.

Song is a veteran who also suffered a back injury during a military deployment. Rapaport says that the two met and hit it off because they both had to stretch at the back of the classroom each day to ease the pain of long periods of sitting through graduate classes at USC.

Engaging The Injured

“We were working on the idea for our class project, determining if it was going to be feasible,” Rapaport said. “We got a lot of attention, and a lot of physical therapists that we were interviewing were saying, one of the biggest issues that they have is patient engagement.”

What Rapaport and Song found in their survey of PTs is common knowledge in the industry. In fact, according to a study from 2022*, only 35% of patients adhere to their rehab protocol following surgery for several reasons, including ease of access to the exercises they are supposed to do. Most PTs hand out their instructions on paper, which patients frequently lose or discard. Kenko seeks to solve that problem by making physical therapy exercises available digitally.

“Instead of handing their patients a sheet of paper,” Rapaport said, “PTs give them (patients) a code from Kenko to be able to download the platform. Now, patients will have guided videos that physical therapists get to curate based upon the patient’s needs, as well as their own preferences. And it helps incentivize the patient because they can follow along, anytime, anywhere on their phone.”

Kenko Physical Therapy offers a secure platform where PTs can either choose from a library of video content that shows patients how to correctly do specific rehabilitation exercises or upload their own videos for their patients and prescribe those movements through the app. Rapaport points out that there’s a gamification element to the app. It uses a graphic similar to those on Apple Watches to show how close a patient is to achieving their exercise goals. It also allows physical therapists to monitor patient progress.

Since neither Rapaport nor Song are physical therapists, they have a PT advisor, Cheri Chan, who performs the exercises in the video library.

The platform is currently a Business-to-Business-to-Consumer model. Physical therapists sign up to use the platform and pay a fee. They then have access to the video library and secure ways to transmit and prescribe video exercises for their patients. The application offers PTs progression data on how the patient is doing with the exercises and gives patients incentives (like digital badges) for completing their workouts.

Kenko Physical Therapy is part of the current Long Beach Accelerator cohort. Rapaport says it’s been invaluable to the company’s growth, which now boasts 49 customers and a staff of seven people, including the two founders. Rapaport says that Kenko has “gained a lot of great value” from the LBA, including access to a great CFO mentor who helped the company organize its books.

Rapaport is also very positive about the LBA capital partner, Sunstone Management, and its impact on the business, saying, “It’s been great to have a supporter, not only financially, but an organization that is comfortable with, like helping give us a little bit more network resources as well.”
