Early developmental support for preterm infants based on exploratory behaviors: A parallel randomized controlled study.

INTRODUCTION: Preterm infants are at high risk for developmental disabilities, and their parents are at increased risk for high stress. Early intervention programs are applied to reduce these adverse outcomes. The primary aim is to compare the efficacy of the novel Explorer Baby early intervention program for the holistic development of preterm infants. The second objective was to compare the stress levels of their mothers. METHODS: Randomized clinical trial with 38 weeks-6 months corrected age preterm infants at low risk for cerebral palsy, randomly assigned to experimental (Explorer Baby) or active control neurodevelopmental therapy (NDT) groups. Fifty-seven infants were enrolled in the study, and 51 (26 Explorer Baby, 25 NDT) completed it. Bayley III was used as a primary outcome before, during, and after the intervention. RESULTS: When we compared the changes between the groups before and after therapy, no significant differences were found in any of the primary or secondary outcomes (between-group comparisons). When comparing the changes in both groups before and after therapy (in-group comparison), the Explorer Baby group demonstrated significant improvements in cognitive (Hedges' g = .83) and explorative language skills (Hedges' g = .65), whereas the NDT group showed improved parent-child dysfunctional interaction (Hedges' g = 2.66) between T0-T1 and T0-T2. CONCLUSIONS: The Explorer Baby early intervention program may be a preferred option to support premature infants without brain injury, as it shows greater skill acquisition than NDT, although not statistically significant. Both methods are safe as they support premature babies without negatively affecting mothers' overall stress levels.

Validity and reliability of the Turkish version of the pediatric motor activity log-revised (PMAL-R) for 2-17 year old children with hemiparetic cerebral palsy.

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.
