Extracorporeal Shock Wave Therapy in Botulinum Toxin-Treated Patients With Post-Stroke Ankle Plantar Flexor Spasticity
Starting soon · Not applicable
Conditions studied: Stroke, Post-stroke Spasticity of the Lower Limb, Post-Stroke Spasticity, Spasticity of the Plantar Flexors, Spasticity, Post-Stroke
In brief
The goal of this clinical trial is to learn if radial Extracorporeal Shock Wave Therapy (rESWT) is effective in reducing ankle plantar flexor spasticity and improving walking functions in stroke patients who have already received Botulinum Toxin type A (BoNT-A) injections. The main questions it aims to answer are: * Does adding rESWT to standard physical therapy significantly lower muscle spasticity in patients who have received BoNT-A, compared to receiving physical therapy alone after the injection? * Does combining rESWT with BoNT-A injection improve functional walking parameters (such as gait speed, cadence, and step length) and daily life independence more than the BoNT-A and physical therapy combination alone? * Can rESWT induce additional structural and flexibility improvements in the BoNT-A injected gastrocnemius muscle, as measured objectively by ultrasound imaging and strain elastography? Researchers will compare a group of participants receiving both rESWT and conventional physical therapy (Group 1) to a comparison group receiving only conventional physical therapy (Group 2) to see if rESWT provides additional clinical benefits. All participants in both groups will have already undergone routine BoNT-A injections one week prior to starting the study treatments. Participants will: * Undergo a 3-week conventional physical therapy and rehabilitation program, consisting of 2 to 3 hours of therapy per day, 5 days a week. * Receive 3 weekly sessions of rESWT (2000 pulses per session applied to the calf muscles) if they are randomized into the rESWT group. * Attend clinical evaluation visits and objective assessment sessions-including high-tech computerized gait analysis and specialized musculoskeletal ultrasound imaging-before the treatment, at the end of the 3rd week, and at a 12-week follow-up.
