5.5. Assessment
Following an evaluation that encompassed gathering demographic information (age and sex), reviewing medical records, assessing prior medications or therapies, examining previous BTX-A injections, measuring vital signs, conducting physical examinations, and conducting laboratory tests on blood and urine, including a pregnancy test, suitable individuals were recruited. During the treatment session, participants received BTX-A injections into the specific muscles within 2 weeks of the initial screening. Follow-up evaluations took place at 4, 8, and 12 weeks following the BTX-A injection.
