Abstract
Background
Parkinson's disease (PD) affects motor function and muscle performance, which are closely linked to muscle architecture (MA). Ultrasound (US) provides a non-invasive method to assess MA, yet its application in PD remains underexplored. This review aimed to map and synthesise existing research on US assessment of MA in individuals with PD to clarify how US imaging methodologies contribute to understanding muscle structure and function in this population.
Methods
This scoping review was conducted following established guidelines and searching these databases: Scopus, PubMed, Web of Science Core Collection, MEDLINE and CINAHL Ultimate.
Findings
Of the 913 records identified, 20 studies met the inclusion criteria. Research varied in design, US measurement methodology, and measurement and reporting approaches. The synthesis revealed that while MA at rest was largely preserved in PD with notable exceptions, muscle fascicle responsiveness during contraction was significantly impaired, potentially due to rigidity. MA differences were associated with PD clinical manifestations (i.e., bradykinesia and rigidity) and reduced functional performance. PD-related comorbidities including sarcopenia, camptocormia, and dysphagia were found to further affect MA, exacerbating muscle degradation and remodelling. Exercise was found to alter the structural characteristics of MA, suggesting beneficial adaptive potential.
Significance and interpretation
Despite consistent evidence of altered MA and muscle responsiveness in PD, methodological heterogeneity and small samples limit firm conclusions. Standardised US protocols and longitudinal studies are needed to clarify the relationship between MA, functional performance, and PD clinical features, and to evaluate the effects of exercise and rehabilitation on muscle structure and strength.
期刊介绍:
Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field.
The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management.
A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly.
Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians.
The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time.
Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
