The Effect of Capacitive and Resistive Electrical Transfer Therapy on Hamstring Injuries

The Effect of Capacitive and Resistive Electrical Transfer Therapy (CRET) on the Return to Play Time in Elite Soccer Players With Hamstring Strain Injuries

Sponsor

Hacettepe University

Enrollment

22 participants

Start Date

Feb 10, 2026

Study Type

INTERVENTIONAL

Conditions

Hamstring Injury

Summary

The aim of this study 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. We thought that CRET could have positive effects on tissue healing in the subacute phase of hamstring injuries.

Eligibility

Min Age: 18 YearsMax Age: 40 Years

Inclusion Criteria3

History of acute onset hamstring pain.
Grade I or II hamstring strain injury confirmed by Magnetic Resonance Imaging (MRI) within the first 5 days following the injury.
No history of anterior cruciate ligament (ACL) reconstruction.

Exclusion Criteria3

Presence of neurological symptoms.
Loss of superficial sensation or skin pathologies that may prevent CRET application.
Refusal to sign the approval form.

Interventions

DEVICET-Plus; Wintecare SA, Chiasso, Switzerland

Experimental Group (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.

OTHERExercise

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