The Effect of Whole-Body Vibration Therapy Following Botulinum Toxin A Injection on Spasticity and Balance in Stroke Patients

The purpose of this clinical study is to evaluate the effect of Whole Body Vibration (WBV) therapy, applied two weeks after botulinum toxin type A (BoNT-A) injection, on spasticity and balance parameters in individuals with stroke who have ankle spasticity. The main questions it aims to answer are: Adjuvant WBV therapy administered after BoNT-A injection; * Does it effectively improve spasticity? * Is it an effective intervention for balance and walking functions? Researchers will compare the application of WBV to a placebo application (a vibration-free application) to evaluate the effect of adjuvant WBV therapy administered after BoNT-A injection on ankle spasticity, balance, and walking function in individuals with stroke.
