Quality of upper extremity skills and disability inventory via manual ability classification in children with neonatal brachial plexus palsy

PurposeThe aim of study was to investigate the relationship between upper extremity skill quality and disability inventory according to manual ability classification system in children with neonatal brachial plexus palsy (NBPP).Materials and methodsChildren with NBPP were included between the ages of 4-7.5 years. Children were classified in Manual Ability Classification System (MACS). Upper extremity skill quality was evaluated with Quality of Upper Extremity Skills Test (QUEST), disability status was assessed with Pediatric Evaluation of Disability Inventory (PEDI).ResultsTotal of 63 children (girls:31/boys:32), and mean age was 6.32 +/- 1.73 years. 37 (58.73%) of children were at MACS Level-2. According to MACS classification, significant differences were noted in PEDI scores (p = 0.001), dissociated movements (p = 0.016) and grasp (p = 0.002) domains of QUEST. However, no significant differences between QUEST total scores (p = 0.079). PEDI (ROC; AuC = 0.762) and QUEST total score (ROC; AuC = 0.714) were sensitive to difference between groups across MACS in children with NBPP.ConclusionThe PEDI and QUEST are sensitive in distinguishing the disability of children with NBPP at different MACS levels. Assessment of children with NBPP is not limited to functionality, disability, and quality of movement, it is multidimensional. Outcomes measures studies of movement's quality in children with NBPP are needed.
