Ultrasound May Offer A Noninvasive Way to Manage Deep Muscle Stiffness .

Managing stiffness in deep muscles presents a challenge in sports rehabilitation. Researchers at Doshisha University investigated whether ultrasound stimulation could alter passive stiffness in the calf, particularly in the deeper soleus muscle, which is difficult to target with conventional interventions. The findings suggest ultrasound may provide a noninvasive means of modifying muscle stiffness. Further studies must determine whether these changes translate into fewer muscle injuries, improved function or faster return to sport.
