This retrospective study will be conducted by reviewing the medical records of hemiplegic patients who received botulinum toxin treatment between 2017 and 2020 at the Physical Medicine and Rehabilitation outpatient clinic of Istanbul Physical Medicine and Rehabilitation Training and Research Hospital. A total of 35 hemiplegic patients who underwent botulinum toxin injection and had at least two follow-up records (with a 6-month interval) will be included. Sociodemographic and clinical data, stroke-related characteristics, botulinum toxin dosage, injected muscle groups, medications, and comorbidities will be recorded. Functional assessments, including the Functional Independence Measure (FIM) and Brunnstrom stage, as well as spasticity evaluations using the Modified Ashworth Scale and the Global Spasticity Index, will be obtained from patient files.
