Kaia's exercise app eased back pain in an independent assessment

PHTI found that app-based exercise therapy improves pain compared with no physical therapy. Its rating rests on two German studies of the Kaia app, which did not match in-person therapy on function.

  • 2 a person

    In a 12-week study in Germany, Kaia users improved in pain beyond the minimal clinically important difference, while people in standard care did not.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Status
Reported and intended benefits.
Evidence

foundstudiedreportedclaimed

An independent assessment report supports the benefit.

Compared with

Standard care for low back pain under German guidelines. Measured.

The system’s part
Not isolated. The studies compared the whole app program with standard care or in-person therapy, so they do not separate the algorithms from the exercise content. PHTI calls computer vision AI-powered software and marks Kaia's review of patient data as done by AI or algorithm. It does not say whether these algorithms learn from data. All included studies used earlier versions of the app.

Details

AI system

Workflow

The app assigned personalized exercise plans from self-reported information and fitness tests read by computer vision. Users received real-time feedback on their exercises through computer vision, with health coaching.

Follow-up

Conditions for replication

Patients have lower-acuity musculoskeletal conditions. The price suits the purchaser, since PHTI could not estimate the effect on spending.

Healthcare.

Purpose

Kaia Health built the Kaia app to deliver self-directed exercise therapy for back and joint pain, with care plans set by algorithms and feedback from computer vision.
