Purpose: The Pediatric Upper-extremity Motor Activity Log-Revised (PMAL-R) is a structured interview that measures use of the more-affected arm in daily life in children with cerebral palsy (CP). This study investigated the concurrent validity and test-retest reliability of a Turkish version of the PMAL-R.
Materials and methods: The PMAL-R was translated and cross-culturally adapted to Turkish and administered to parents of eighty children with hemiplegic CP between 2-17 years. Its concurrent validity was examined by correlating scores on the PMAL-R How Well and How Often scales with ABILHAND-Kids scores. Fifty parents were re-interviewed after three weeks to establish test-retest reliability.
Results: PMAL-R scores were strongly correlated with ABILHAND-Kids scores (How Well scale, r = 0.78, p < 0.001; How Often scale, r = 0.59, p < 0.001). PMAL-R test-retest reliability (Intraclass correlation; How Often = 0.98, How Well = 0.99) and internal consistency (Cronbach's α; How Often = 0.96, How Well = 0.97) were high.
Conclusions: This translation of the PMAL-R has good reliability and validity for measuring everyday use of the more-affected arm in Turkish children with hemiparesis due to CP between 2-17 years. Implications for rehabilitationAn instrument that evaluates real-world arm use in Turkish children with CP.Reliability and concurrent validity of the Turkish PMAL-R is established in 2-17-year old with upper-extremity hemiparesis.Systematic replication of the clinimetric properties of the English PMAL-R is demonstrated in a wider age range than previously, 2-17 years vs. 2-8 years.Reliability and concurrent validity of the PMAL-R is shown in both children with right and left hemiparesis.
