Effect of Lidocaine Phonophoresis Versus Pulsed Ultrasound on Myofascial Pain Syndrome in Athletic Children

A topical anesthetic gel lidocaine has been widely used as a local anesthetic to reduce the pain and discomfort. It provides local analgesia by blocking the initiation and transmission of impulses. Lidocaine topical anesthetic gel allows the use of high concentrations of the anesthetic bases without concern about local irritation, uneven absorption or systemic toxicity (Argoff, 2000 ). So, the aim of this study is to compare between the effect of lidocaine phonophoresis and pulsed ultrasound in myofascial pain syndrome in swimmers children.
