Effects of High Intensity Laser Therapy in Muscle Injuries

Kurzzusammenfassung

Muscle injuries are frequent traumatic events in daily life, particularly during sports. In sports, their incidence varies from 10% to 55% of total injuries. According to the Mueller Wohlfart classification, muscle injuries are classified into direct traumatic injuries (contusion-laceration) and indirect traumatic injuries, which are further divided into non-structural injuries (grade I and II) and structural injuries. Structural lesions are further divided into partial muscle lesions (grade III): 3 A, minor partial lesion, i.e. lesion of one or more primary bundles with a secondary bundle; 3 B, moderate partial lesion, i.e. lesion of at least one secondary bundle and with a rupture area \< 50% of the muscle surface; and (sub)total muscle injury (grade IV).
