Segmental bioelectrical impedance analysis offers a practical, non-invasive method for assessing body composition and monitoring hydration status. This technique is valuable in both healthy and clinical settings, including critical care and haemodialysis.

Area of Science:

  • Physiology
  • Biomedical Engineering

Background:

  • Bioelectrical impedance analysis (BIA) is a non-invasive, rapid, accurate, and practical method for assessing body composition.
  • Recent evidence supports BIA's utility in monitoring hydration status.
  • This review critically examines segmental BIA approaches and applications in healthy and clinical contexts.

Purpose of the Study:

  • To critically review different approaches and applications of segmental bioelectrical impedance analysis.
  • To examine the use of segmental BIA in healthy and clinical populations, including children and diverse ethnic groups.
  • To explore applications in body composition assessment and monitoring fluid balance changes.

Main Methods:

  • Review of published literature on segmental bioelectrical impedance analysis.

  • Description of the set-up for the segmental BIA method.
  • Examination of applications across various populations and clinical scenarios.

    • Main Results:

    • Segmental BIA can assess appendicular lean body mass, estimate muscle volume, and explore muscle size-strength relationships.
    • The method shows potential for bedside detection of fluid accumulation in critical care.
    • Published applications in healthy populations and field studies indicate method validity.

    Conclusions:

    • Segmental bioelectrical impedance analysis is a valid method for assessing body composition and monitoring fluid balance.
    • Applications span healthy individuals, children, diverse ethnic groups, and clinical situations like haemodialysis and surgery.
    • The technique is a promising tool for bedside fluid accumulation detection in critical care settings.
