Researchers are evaluating the long-term effects of focused extracorporeal shock wave therapy (fESWT) on spasticity in the triceps surae muscle group in stroke patients. The study aims to compare the outcomes of applying three sessions of fESWT versus a single session, hypothesizing that multiple sessions may provide longer-lasting improvement in spasticity and functionality. Spastic equinus foot, a common complication after stroke, significantly affects mobility and quality of life, making this research important for stroke rehabilitation. The study will enroll 60 stroke patients with spastic equinus foot, randomly assigning them to two groups. One group will receive one session of fESWT, while the other will receive three weekly sessions over three consecutive weeks. The shock wave therapy will target the gastrocnemius medial and lateral muscles and the soleus muscle, with precise muscle locations identified by ultrasonography. The therapy is delivered using a Duolith SD1 device with specific parameters of 0.15 mJ/mm2 energy, 4-5 Hz frequency, and 1500 shocks per muscle. Participants will be assessed before the first therapy session and followed up at weeks 1, 4, 8, 12, 20, 24, 36, and 48 after the last session. Evaluations include the Modified Ashworth Scale for spasticity, passive range of ankle motion, mobility and balance tests, spasm frequency, and quality of life scales. Researchers will also monitor adverse events throughout the study to ensure safety and gather comprehensive long-term data on treatment effects.
