Screening for Vertebrobasilar pathology and upper cervical instability by physical therapists treating neck pain: a retrospective chart review.

In the present study, physical therapists infrequently documented performance of vertebrobasilar or upper cervical ligament instability screening for adults with neck pain, even in the presence of risk factors or preceding manual therapy. Further research should corroborate these findings and explore reasons for use/avoidance of screening.
