Resumen:
Background and Aims Percutaneous needle electrolysis has shown to be effective for the treatment of chronic tendinopathies, however, the scientific evidence available regarding acute muscle lesions is scarce. Lesions to the hamstrings caused by indirect mechanisms represent the most common muscle lesion in football (its incidence increases each year) with a high rate of recurrence. The aim was to evaluate whether the application of percutaneous needle electrolysis and a program of functional exercise decreases the times for return to competition after an injury to the hamstrings in athletes, and to compare performance data of subjects during competition before and after the injury.
Methods A case series. Two professional football players, belonging to a first league team in Spain with a grade 2 lesion in the semitendinosus muscle on the proximal level. The affected muscle structure was assessed using ultrasound (Logiq GE E9, probe ML6–12) and functionality was evaluated based on data of the Global Positioning System (GPS), comparing the data obtained during the process of re-adaptation with data prior to the lesion. Percutaneous needle electrolysis was performed under ultrasound guidance at 48...
