Upper-limb function in Brachial Plexus birth palsy: Does the Pediatric Outcomes Data Collection Instrument correlate with the Brachial Plexus Outcome Measure?

Functional outcome assessment for children with brachial plexus birth palsy (BPBP) is essential. We aimed to investigate the association between the Brachial Plexus Outcome Measure (BPOM) and the Pediatric Outcomes Data Collection Instrument (PODCI) in children with BPBP and healthy matched controls, and to explore upper-limb function and the discriminative properties of the two tests. Thirty children, aged 6-14 years, diagnosed with BPBP and undergoing shoulder tendon transfer and 20 age-matched healthy controls were included. In both groups, the Turkish version of the PODCI, used to evaluate daily living activities, was implemented. The Turkish version of the BPOM, specifically developed for BPBP, was applied in children with BPBP. Test results, demographic and clinical characteristics were recorded. The mean age of children with BPBP was 8.53 ± 2.53 years and their BPOM Activity scale score was 42.93 ± 8.28. The PODCI Upper Extremity Function score (74.97 ± 23.49 vs. 100) and the PODCI Global Functioning score (89.20 ± 7.73 vs. 99.36 ± 7.73) were significantly lower in the BPBP group (p < 0.01). While there was a significant and very strong relationship between the BPOM Activity and PODCI Global Functioning scores (r = 0.845; p = 0.037), no correlation was found between the BPOM Self-Evaluation scale and PODCI Global Functioning score (r = 0.456; p = -0.141). The PODCI correlated with the BPOM Activity scale, providing an appropriate alternative measurement for upper-limb function in children with BPBP after shoulder tendon transfer.
