The Efficacies of Medicinal Leech Therapy and Platelet Rich Plasma Injection added to Muscle Stretching Exercises in the Treatment of Myofascial Pain Syndrome

Myofascial pain syndrome is among the most common cause of physical disability and severe chronic muscle pain and affect millions of people worldwide. So far muscle stretching exercises and some therapeutic interventions have been recommended with various effects. Sixty-six patients with myofascial pain syndrome due to trigger points in trapezius muscle were included in this study. Patients were divided randomly into 2 groups of 33 patients: group 1; medicinal leech therapy group, group 2; platelet rich plasma injection group. To the first group, 4 medicinal leech were applied to the trigger points 2 times in a 4 week interval . To the second group, a total of 2 ml platelet rich pla sma was administered to each trigger point 2 times in a 4 week interval. All patients had also taught and given trapezius muscle stretching exercises for ten minutes as a daily diary schedule for 12 weeks. At the end of the study there was a significant decrease in visual analogue scale scores in both groups, while a significant increase in pain threshold values in medicinal leech therapy group (p
