NeckSmart Solution

Butterfly Method

The Butterfly Method is the signature assessment protocol of the NeckSmart solution. NeckSmart measures the patient’s ability to use head-neck movements to track a moving target following an unpredictable trajectory.

The healthcare professional may thereby detect abnormalities in neck movements, which may be the cause of chronic neck pain. The Butterfly Method is based on 15 years of clinical research and is patented in Europe, North America, and Australia.
