Overview
This observational study aims to evaluate pain and upper extremity function in adults with obstetric brachial plexus palsy who underwent shoulder tendon transfer surgery using the Modified Hoffer technique during childhood. Data on the long-term clinical outcomes of this surgical procedure in adulthood are limited. Participants with obstetric brachial plexus palsy and healthy age-matched individuals will be assessed in a single session. The evaluations will include pain, range of motion, muscle strength, upper extremity functional status, social appearance anxiety, and role performance. The study aims to describe the clinical profile of adults with obstetric brachial plexus palsy after Modified Hoffer tendon transfer and compare their outcomes with healthy peers.
Description
This study is designed as a master's thesis and will be conducted as an observational, cross-sectional, assessment-based study. The study will be carried out at the Department of Physiotherapy and Rehabilitation, Biruni University. Ethical approval has been obtained from the Biruni University Scientific Research Ethics Committee. The study will be conducted in accordance with the principles of the Declaration of Helsinki, and written informed consent will be obtained from all participants before participation.
The study will include adults with obstetric brachial plexus palsy who underwent shoulder tendon transfer surgery using the Modified Hoffer technique during childhood and healthy age-matched individuals. Individuals with obstetric brachial plexus palsy who have had at least five years since surgery will be included. Participants will be recruited on a voluntary basis among individuals referred by physicians, followed clinically, or admitted to the Department of Physiotherapy and Rehabilitation at Biruni University. All assessments will be performed by the same researcher in the Patient Assessment Laboratory of the Department of Physiotherapy and Rehabilitation.
The primary outcome of the study is pain. Pain intensity will be assessed using the Numeric Rating Scale. Secondary outcomes will include upper extremity range of motion, muscle strength, functional status, social appearance anxiety, and role/activity performance. Shoulder and forearm range of motion will be assessed for flexion, abduction, external rotation, internal rotation, supination, and pronation using the Kinvent K-Move Digital Goniometer. Muscle strength will be assessed using the MicroFET-2 digital handheld dynamometer for the relevant primary muscle groups of the shoulder and forearm.
Functional status will be evaluated using the Shoulder Pain and Disability Index and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire. Social appearance anxiety will be assessed using the Social Appearance Anxiety Scale. Role performance and perceived activity performance will be evaluated using the Canadian Occupational Performance Measure.
To ensure methodological consistency between the obstetric brachial plexus palsy group and the healthy control group, the same standardized assessment battery will be applied to both groups. Physical and functional upper extremity measurements will be recorded bilaterally to allow comparison between the affected and unaffected sides in individuals with obstetric brachial plexus palsy and between the dominant and non-dominant sides in healthy controls.
The study aims to describe the clinical profile of adults with obstetric brachial plexus palsy after Modified Hoffer tendon transfer and to compare their pain, upper extremity function, range of motion, muscle strength, psychosocial status, and role performance with those of healthy peers.
