Ultrasound and radial extracorporeal shock wave therapies in the treatment of foot spasticity in patients with stroke

This study compared the effectiveness of ultrasound and radial extracorporeal shock wave therapy (RESWT) in the treatment of foot symptoms in patients with stroke. Researchers suggested that both treatments similarly improved these symptoms.  

Spasticity is a common symptom in patients with stroke. It is seen in up to 50% of patients. This is associated with the stiffness of the muscle around the foot. This symptom does not allow the correct movement and stretching of the foot. It affects the quality of life of the patient. Physical therapy is the standard treatment for this symptom. It can use methods such as ultrasound and RESWT.   

Ultrasound therapy consists of sending sound waves through the skin and into the body. These waves cause vibration which can improve muscle function. RESWT involves the application of shock waves that breaks down injured tissue also improving muscle activity. However, there is no study comparing the effectiveness of these two different treatment methods in patients with foot spasticity after stroke.

This study included information about 32 patients with stroke. These patients were assigned to receive 1 session of either ultrasound therapy (16) or RESWT (16).

Both treatments were associated with improved foot symptoms. However, no significant difference in effectiveness was seen between both treatments.

This study concluded that ultrasound treatment had similar effectiveness to RESWT in the treatment of foot spasticity in patients with stroke.

This study had a limited number of participants and a follow-up of only 1 hour. Further, larger studies are needed for stronger evidence.
