Butterfly Method


The Butterfly Method is the signature assessment protocol of the NeckSmart solution. NeckSmartmeasures the patient's ability to use head-neck movements to track a moving target following anunpredictabletrajectory. The healthcare professional may thereby detect abnormalities in neckmovements, which may be the cause of chronic neck pain. The Butterfly Method is based on 15years of clinical research and is patented in Europe, North America, and Australia.
