The aim of this methodological study is to translate the Impact of Brachial Plexus Injury Questionnaire (IMBPIQ) into Turkish, culturally adapt it, and evaluate its validity and reliability for use in adults with brachial plexus birth palsy. The study will include 50 adult participants aged 18 years and older with a diagnosis of brachial plexus birth palsy. Participants will complete the Turkish version of the IMBPIQ, as well as the Disabilities of the Arm, Shoulder and Hand questionnaire and the Short Form-36. The psychometric properties of the Turkish IMBPIQ will be examined using reliability and validity analyses, including internal consistency, test-retest reliability, and construct validity.

Having a diagnosis of brachial plexus birth palsy.
Having the ability to read, write, speak, and understand Turkish.
Agreeing to participate voluntarily in the study and signing the informed consent form.
Having a neurological disease.
Having another orthopedic problem or a history of trauma in the affected upper extremity.
Having a severe cognitive or communication impairment that may prevent completion of the questionnaires or understanding of the study instructions.

The study population will consist of adults aged 18 years and older with a diagnosis of brachial plexus birth palsy who are able to read, write, speak, and understand Turkish.

Case-only
Cross-sectional
Questionnaire Assessment Battery
Other interventionParticipants will complete the Turkish version of the Impact of Brachial Plexus Injury Questionnaire, the Disabilities of the Arm, Shoulder and Hand questionnaire, and the Short Form-36.
Validity and Reliability of the Turkish IMBPIQ
The validity and reliability of the Turkish version of the Impact of Brachial Plexus Injury Questionnaire will be evaluated. Reliability will be assessed using internal consistency and test-retest reliability analyses. Validity will be assessed using construct validity analyses through correlations with related patient-reported outcome measures.
Upper Extremity Disability
Upper extremity disability will be assessed using the Disabilities of the Arm, Shoulder and Hand questionnaire. Higher scores indicate greater upper extremity disability.
Health-Related Quality of Life
Health-related quality of life will be assessed using the Short Form-36. The scale includes subdomains related to physical and mental health, with higher scores indicating better health status.
