Purpose: To establish the validity and reliability of the Turkish version of the Seated Postural Control Measure (SPCM-TR) in children with cerebral palsy (CP).
Methods: The original version of the Seated Postural Control Measure was translated and culturally adapted according to international guidelines. The participants were 124 children with CP, with a mean age of 8.6 ± 2.6 years. The measures were administered by 2 independent physical therapists twice, 1 week apart. Convergent validity was evaluated with the sitting dimension of the Gross Motor Function Measure (GMFM), whereas construct validity was evaluated with the Gross Motor Function Classification System (GMFCS).
Results and conclusions: Cronbach's alpha values of the alignment and function subscales and total score were 0.83, 0.89, and 0.91, respectively. Correlations between SPCM-TR total scores and GMFCS (-0.92) and GMFM (0.91) scores were very good. The intraclass correlation coefficient was excellent (0.90) for intra-rater and inter-rater reliability. The results indicate that the SPCM-TR is a valid and reliable scale in children with CP.
