This study demonstrated that, if measures are to be used across cultures, the items must not only be translated well linguistically but also must be culturally adapted to maintain the content validity of the instrument at a conceptual level across different cultures. This may necessitate several validation studies to ensure and improve consistency in the content and face validity between source and target versions of a questionnaire due to difficulty in detecting subtle differences in the living habits of different cultures.

The Turkish version of the E&R GMFCS is shown to be reliable and valid for assessment of Turkish CP children.

Botulinum toxin type A can be both safe and effective in relieving spasticity in pediatric patients with cerebral palsy. In our prospective study, we evaluated the functional effect of botulinum toxin A in spastic diplegic-type cerebral palsy. Patients were examined on enrollment and at 1, 3, and 6 months after injection. Passive dorsiflexion of the ankle joint was measured using a goniometer as an angle of possible maximal dorsiflexion with the knee extended and flexed. Spasticity was graded using the Modified Ashworth Scale. Selective motor control at the ankle was assessed, and observational gait analysis was done. The functional status of the patients was determined by using the gross motor classification system. Botulinum toxin A was injected into the gastrocnemius muscle in all patients, and in four patients with concomitant jump knee gait, a hamstring muscle injection was added. Fourteen patients were included in the study. The mean age was 58.81 +/- 15.34 months. Following injection, spasticity was clinically decreased and statistically significant improvement was noticed in all clinical parameters after 1, 3, and 6 months of injection. The improvement in the clinical parameters decreased after 6 months but not to the baseline. One patient was Level II, four patients were Level III, and six patients were Level IV according to the Gross Motor Function Classification System at baseline. Improvement in the gross motor classification system is continued after 6 months in 12 children. The main goal of spasticity treatment in cerebral palsy is functional improvement. In our study, most of our patients had functional improvement according to the gross motor function classification system and did not change at 6 months.
