Read our Stroke research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This small study is testing how botulinum toxin type A works in stroke patients who have developed a condition called spastic equinovarus—where the foot becomes tightened and turns inward. Researchers will give participants the medication as injections into leg muscles and then carefully measure how the muscles, tendons, and nerves change over several months. The goal is to understand how this treatment works so doctors can improve how they prescribe it and help patients get better long-term results.
After a stroke, many patients develop tight, stiff muscles in the foot that can make walking difficult. While this medication is already used to treat this problem, doctors don't fully understand exactly how it changes the muscles and nerves over time. This study will fill that gap so future treatments can be more personalized and effective.

You will come for 4 visits over about 5–6 months. At the first visit, you'll have baseline measurements. At the second visit (5–7 weeks later), you'll receive the botulinum toxin injections into your calf and shin muscles. At visits 3 and 4, researchers will use ultrasound imaging and special tests to measure how your muscles, tendons, and nerves have changed in response to the treatment. Each visit involves the same measurements so doctors can track changes over time.
