Kaia Health’s App-Based Back Pain Treatment Outperforms Standard Physiotherapy in Clinical Trial

Kaia Health, a digital therapeutics company, announced results from the first randomised controlled trial of its app-based therapy program for patients with non-specific low back pain. Detailed results of the study were published in the journal NPJ Digital Medicine and showed that patients using Kaia, a downloadable app for back pain, reported significantly lower pain levels compared to the control group treated with physiotherapy and online education.

“This study can help add to the growing body of evidence that generally supports the use of multimodal treatments for chronic conditions,” said Thomas R. Tölle, M.D., Ph.D., Head of Pain Medicine, Technical University Munich, Germany. “Within this study, we saw a notable benefit for people managing low back pain when delivering multimodal treatment through the digital modality of the smartphone, as is done in the Kaia app.”

Low back pain is one of the leading causes of global disability, and treatment is expensive.1,2 According to the Office for National Statistics, back, neck and muscle problems account for almost 31 million days of work lost in 2013 costing the UK economy £14 billion per year – with an estimated one-third of the UK adult population affected by back pain annually.3,4

“As a company, we want to support the improvement of the current standard of care for people living with back pain,” said Konstantin Mehl, Founder and CEO, Kaia Health. “And while these study results are promising, we will be initiating a similar U.S.-based study looking at the use of the Kaia app for self-management of back pain.”

About the Randomised Controlled Trial5

In the study, analysed patients with low back pain were treated using two methods. The first group used Kaia Health’s multi-platform mHealth app (n=42), while a second control group was treated using a standard therapy program consisting of 6 once-weekly, in-person physiotherapy sessions guided by a certified therapist plus sophisticated online education about back pain delivered to patients weekly with a motivating email (n=44). Both groups were encouraged to live an active lifestyle and perform the therapeutic exercises at home, but the app provided three therapy modules – back pain education; physiotherapy; and mindfulness and relaxation techniques – and recommended a 3 to 4 times-per-week exercise plan that could be personalised for each user. App users also could interact with a human coach via the app if they had questions.

Both the control and Kaia app treatment groups experienced significant pain reduction over the course of 12 weeks. However, after 3 months, patients using the Kaia app reported substantially larger decrease in their back pain intensity than control group patients: 2.4 vs. 2.0, respectively, on a numeric rating scale ranging from 0 to 10 (where higher numbers represent more pain). The decrease suggests that Kaia may be an effective treatment for low back pain over a 3-month timeframe.
