Brief Summary

The goal of this clinical trial is to evaluate the effects of capacitive resistive electric transference (CRET), which is frequently used in clinics and sports clubs for professional soccer players with hamstring injuries. The main questions it aims to answer are: Return to sports time Treatments sessions number Muscle oxygen saturation The investigators will administer the treatment to a experimental group to see if CRET therapy is effective. The investigators will also administer a standard rehabilitation program to both the control and experimental groups. Participants will: Come for treatment and evaluations 3 times a week until participants meet the criteria for returning to sports.

Capacitive and Resistive Electrical Transfer Therapy (CRET) experimental

EXPERIMENTAL

In addition to the standard rehabilitation program, the experimental group will receive Capacitive and Resistive Electrical Transfer Therapy (CRET) (T-Plus; Wintecare SA, Chiasso, Switzerland) at the end of each session.

Device: T-Plus; Wintecare SA, Chiasso, Switzerland; Other: Exercise

Control

ACTIVE COMPARATOR

Participants in the control group will undergo a standard, evidence-based, three-stage hamstring rehabilitation program.

Other: Exercise

Interventions

Exercise OTHER

A standard hamstring rehabilitation program consisting of three phases will be implemented.

T-Plus; Wintecare SA, Chiasso, Switzerland DEVICE

Experimental Group (Capacitive and Resistive Electrical Transfer Therapy (CRET) Therapy): In addition to the standard rehabilitation program, CRET therapy (T-Plus; Wintecare SA, Chiasso, Switzerland) will be applied at the end of each session to the experimental group. Positioning: The athlete will be placed in a prone position, with the passive electrode placed under the quadriceps muscle and the active electrode applied in the direction of the hamstring muscle fibers using classic massage maneuvers. Dosage and Duration: The treatment will last a total of 20 minutes, consisting of 10 minutes in resistive mode followed by 10 minutes in capacitive mode. Intensity: The application will start at 70% intensity. If the thermal sensation reaches a level that disturbs the athlete, the intensity will be gradually reduced by 10% to achieve the maximum tolerable thermal effect.
