Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • recovery of pain

    The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain."

    From enrollment to 3 weeks and 3 months

Secondary Outcomes (3)

  • Size of the lesion

    From enrollment to 3 weeks and 3 months

  • Frequency of relapses

    From enrollment to 3 weeks and 3 months

  • Return to sport activity

    From enrollment to 3 months

Study Arms (2)

High Energy Laser Group

EXPERIMENTAL

The multimodal high energy laser therapy treatment with thermal control (THEAL) will be delivered with an Ixyon XP device (Mectronic, Bergamo, Italy) which allows the delivery of 4 wavelengths (650 nm, 810 nm, 980 nm and 1064 nm), with continuous and pulsed mode, average power up to 30 W, administering 10 sessions every other day. The patients will simultaneously carry out the rehabilitation treatment exercises, as was expected in the control group.

Device: High Energy Laser GroupOther: Exercise

Exercise Group

ACTIVE COMPARATOR

All patients will receive a rehabilitation protocol of 5 weekly sessions lasting approximately 60 minutes, for approximately 3 weeks. During the early post-injury phases, the protocol will include isometric exercises to strengthen core stability. These exercises will each be performed for 3 sets of 30 seconds, although the number of sets and repetitions may vary depending on the athlete's response.
