The Food and Drug Administration (FDA) has cleared a new application that allows clinicians to objectively measure a patient’s balance. The K-D Balance (King-Devick technologies) application works with an iPhone or iPod Touch and is placed in a wearable device on the body to provide device stabilization. 

Rather than measuring single-leg stance, the application assesses 3 key balance metrics: (1) double stance, (2) right tandem stance, and (3) left tandem stance. The device instructs users to take the stances via a step-by-step voice guide; the application score is then derived from the individual’s movements using the device’s internal accelerometer. The application uses HIPAA-compliant cloud-based technology, allowing clinicians to access and assess a patient’s balance scores.

The Company states that the application can be used to measure balance in aging patients as well as those with conditions such as concussion, orthopedic injury, vestibular dysfunction, headaches, and neurodegenerative diseases (Parkinson’s disease, multiple sclerosis).

“Our studies showed that K-D Balance exhibited excellent test-retest reliability and consistently provided quantitative measures of poorer balance performance in patients with neurologic conditions,” said Bert Vargas, MD, neurologist and Director of the Sports Neuroscience and Concussion Program at UT Southwestern in Dallas.

The application will be available for purchase in May 2018.
