Comparative analysis of ultrasound changes in the vastus lateralis muscle following myofascial release and thermotherapy: A pilot study

Summary Objectives This study aimed to compare the effects of myofascial release (MFR) and hot pack therapy (HPT) on fascial gliding and flexibility of the vastus lateralis muscle. Methods Three treatments were applied to the left vastus lateralis muscles of each participant (12 healthy males): MFR...

Description
Summary:Summary Objectives This study aimed to compare the effects of myofascial release (MFR) and hot pack therapy (HPT) on fascial gliding and flexibility of the vastus lateralis muscle. Methods Three treatments were applied to the left vastus lateralis muscles of each participant (12 healthy males): MFR for 4 min, superficial HPT for 10 min, and superficial HPT for 20 min. Deep fascial motion was measured by B-mode ultrasound, whereas muscle stiffness was measured by real-time elastography (RTE) and a durometer before and after the interventions. Results Only MFR resulted in changes in both deep fascial motion and muscle stiffness measured by RTE. Durometer-measured muscle stiffness revealed changes following both MFR and 20-min HPT but not 10-min HPT. Conclusions HPT may produce only superficial effects. Because MFR improved all measured parameters, continuous stretching and pressure are probably important for improving fascial gliding and flexibility of the vastus lateralis muscle.
