A pilot study to determine the efficacy of therapeutic class IV laser treatment on local muscle spasm associated with myofascial pain syndrome in patients with neck pain

Pilot study consisting of ten patients with at least one month of myofascial pain. Patients underwent two weeks of class IV laser treatment. A majority of the patients who underwent laser therapy showed improvement in pain assessment at 25 and 30 days post treatment. This study warrants a larger, controlled clinical study.
