Background: Myofascial pain syndrome (MPS) is a complex pain syndrome characterized with trigger points (TrPs) in skeletal muscles. Ultrasound (US) therapy is one of the main devices used in physical therapy, for the treatment of TrPs in MPS. Purpose: This study aimed to compare between continuous, pulsed (1:1 &1:4) and sham ultrasound in subjects with myofascial trigger points in the upper fibers of trapezius muscle. Subjects: Sixty subjects (37 males and 23 females) with active trigger points on the upper fibers of trapezius, aged 18 to 30 years participated in the study. Methods: Subjects were randomly divided into four equal groups, including Group A was treated with continuous ultrasound (3MHz, 1W/cm²), Group B was treated with pulsed ultrasound (3MHz, 1W/cm², 1:1 ratio), Group C was treated with pulsed ultrasound (3MHz, 1W/cm², 1:4 ratio), and Group D, the control group, was treated with sham ultrasound. All treatments applied 5 minutes 5 days per week for 2 weeks. Pressure pain threshold (PPT) was assessed with pressure algometer, pain severity was assessed with visual analog scale (VAS) and quality of life was evaluated with Nottingham health profile (NHP). All evaluations were performed before and after 10 sessions of treatment. Results: There was a significant difference between group (A) and other groups according to PPT as p value (p<0.05). There was a significant difference between group (A) and (C) & (D) according to VAS and NHP as p value (p<0.05). There was a significant difference between group (B) and other groups according to PPT as p value (P<0.05) and no significant difference according to VAS and NHP. There was no significant difference between group (C) and (D) according to PPT, VAS and NHP. Conclusion: Continuous and pulsed (1:1) ultrasound are more effective than pulsed (1:4) and sham ultrasound in the treatment of myofascial pain syndrome. Continuous ultrasound show more improvement than pulsed ultrasound
