Clinical Report: Functional Assessment of the Abdominal Wall in Hernia Patients
Overview
This review identifies and appraises various assessment methods for abdominal wall function (AWF) in hernia patients, highlighting the lack of standardized evaluation tools. Eighteen studies involving 892 participants with different hernia types were analyzed, revealing diverse domains of AWF assessment beyond muscle strength alone.
Background
The abdominal wall's function depends on coordinated interactions among muscles, tendons, fascia, spine, and pelvic floor, essential for regulating intra-abdominal pressure and core stability. Hernia patients often experience impairments in AWF, negatively impacting quality of life and necessitating surgical repair. Despite advances in surgical techniques, there is no consensus on standardized pre- and post-operative functional assessment methods, limiting evaluation of surgical success. This review aims to comprehensively map existing AWF assessment tools to inform clinical practice and research.
Data Highlights
The literature search identified 416 records, with 18 studies meeting inclusion criteria after screening. These studies included 892 participants aged 12 to 76 years, predominantly male (68.7%). Hernia types included ventral (18.8%), incisional (54.6%), and unilateral inguinal (23.2%) hernias, with 3.4% healthy controls. Study designs comprised observational (cross-sectional and cohort) and clinical trials (randomized and non-randomized).
Key Findings
AWF encompasses multiple domains including muscle strength, postural control, trunk mobility, and core stability.
There is significant heterogeneity in assessment methods and tools used across studies, with no standardized approach.
Most assessments focus on abdominal muscle strength, while other functional domains remain under-investigated.
Patient-reported outcome measures often include function but lack validated functional assessment components.
Reliability and validity data for many assessment tools are limited or inconsistently reported.
The review highlights the need for a comprehensive, standardized AWF assessment framework applicable in clinical and research settings.
Clinical Implications
Clinicians should recognize the multifaceted nature of abdominal wall function and the current absence of standardized assessment tools when evaluating hernia patients. Incorporating multiple functional domains beyond muscle strength may provide a more holistic understanding of patient status pre- and post-surgery. Development and adoption of validated, reliable assessment methods could improve surgical outcome evaluation and guide rehabilitation strategies.
Conclusion
This review underscores the diversity and inconsistency of AWF assessment methods in hernia patients and advocates for the development of comprehensive, standardized functional evaluation tools to enhance clinical care and research outcomes.
