Summary

This study examines the early use of botulinum toxin in patients recovering from their first stroke to help reduce muscle stiffness and improve mobility. Spasticity, a condition that causes abnormal muscle tightness, is a common complication following strokes. It can result in decreased independence, pain, joint contractures, and difficulty performing daily activities. Early intervention is critical to prevent long-term complications and improve recovery outcomes.The participants are men and women aged 18 and older who have recently experienced their first stroke. These patients, admitted to the Regional General Hospital No. 1 "Lic. Ignacio García Téllez" in Mérida, Yucatán, will receive botulinum toxin injections alongside a comprehensive rehabilitation program. Botulinum toxin, commonly known for its muscle-relaxing effects, will be administered within the first three months after the stroke. This early timeline aims to maximize recovery by addressing muscle tightness before it worsens.The study will evaluate how the combination of botulinum toxin and physical therapy affects muscle tone, functional independence, and overall quality of life. Key measurements include the Modified Ashworth Scale (MAS) to assess muscle stiffness, the Barthel Index to evaluate daily activity independence, and cognitive assessments to monitor brain recovery. Patients' progress will be tracked over several months to measure the intervention's short, medium, and long-term impact.Previous research suggests that early application of botulinum toxin can prevent long-lasting muscle contractures and improve mobility, but more studies are needed to confirm its benefits in stroke rehabilitation. The results of this research could help establish early botulinum toxin injections as a standard practice in stroke recovery programs, reducing disability and healthcare costs while improving the lives of stroke survivors.

Interventions

DRUG

Botulinum Toxin Type A (BoNT-A)

This intervention involves the early administration of botulinum toxin type A (BoNT-A) within the first 12 weeks after a cerebrovascular event. The injections target muscles affected by spasticity, aiming to reduce abnormal tone, prevent contractures, and improve functional mobility. BoNT-A works by blocking acetylcholine release at the neuromuscular junction, resulting in muscle relaxation. Ultrasound guidance or anatomical landmarks will be used for accurate injection. This early intervention capitalizes on the neuroplastic window and is combined with standard rehabilitation to enhance motor recovery and prevent long-term complications.
