Effectiveness of Physiotherapy interventions plus Extrinsic Feedback for neck disorders: A systematic review with meta-analysis

There is very low quality of evidence that Physiotherapy intervention + EF is more effective than Physiotherapy intervention alone or control for short-term pain, but not for disability. Physiotherapy intervention plus EF was more effective than Physiotherapy alone for acute neck pain, but not for chronic pain or disability. There was high risk of bias within included studies. Future studies are likely to change the estimates of the effects of Physiotherapy intervention plus EF on neck rehabilitation.
