Brief summary

Obstetric brachial plexus palsy (OBPP) arises from perinatal injury to the brachial plexus, resulting in varying degrees of motor and sensory impairment in the upper extremity. While existing assessment instruments primarily target unilateral limb function, they frequently overlook bimanual capabilities, which are essential for functional independence. This study aims to investigate the utility of the Duruöz Hand Index (DHI) as a reliable, valid, and practical instrument for evaluating functional limitations in individuals with OBPP. A cohort of 21 pediatric patients (aged 6-18 years) with OBPP was recruited from a tertiary university hospital in Turkey. Functional assessment included grip and pinch strength, range of motion, and upper extremity performance, measured using the Modified Mallet Classification, Brachial Plexus Outcome Measure (BPOM), Pediatric Outcomes Data Collection Instrument (PODCI), and DHI

Design outcomes

Primary

Measure	Time frame	Description
Validity and reliability	At baseline	The primary outcome measure was the Duruöz Hand Index (DHI), which was investigated to determine whether it can adequately capture impairments in bimanual function during daily activities and provide a comprehensive assessment of functional disability in patients with OBPP. To evaluate the validity of the DHI, its correlations with established outcome measures-including the Modified Mallet Classification, Brachial Plexus Outcome Measure (BPOM), Pediatric Outcomes Data Collection Instrument (PODCI), as well as grip and pinch strength and range of motion-were examined. Reliability was assessed through internal consistency using Cronbach's alpha.
