Diagnosing sarcopenia: Functional perspectives and a new algorithm from the ISarcoPRM.

Sarcopenia is an important public health problem, characterized by age-related loss of muscle mass and muscle function. It is a precursor of physical frailty, mobility limitation, and premature death. Muscle loss is mainly due to the loss of type II muscle fibres, and progressive loss of motor neurones is thought to be the primary underlying factor. Anterior thigh muscles undergo atrophy earlier, and the loss of anterior thigh muscle function may therefore be an antecedent finding. The aim of this review is to provide an in-depth (and holistic) neuromusculoskeletal approach to sarcopenia. In addition, under the umbrella of the International Society of Physical and Rehabilitation Medicine (ISPRM), a novel diagnostic algorithm is proposed, developed with the consensus of experts in the special interest group on sarcopenia (ISarcoPRM). The advantages of this algorithm over the others are: special caution concerning disorders related to the renin-angiotensin system at the case finding stage; emphasis on anterior thigh muscle mass and function loss; incorporation of ultrasound for the first time to measure the anterior thigh muscle; and addition of a chair stand test as a power/performance test to assess anterior thigh muscle function. Refining and testing the algorithm remains a priority for future research.

EURO-MUSCULUS/USPRM Global Report on Musculoskeletal Ultrasound Publications.

The developments in technology have improved access to the use of musculoskeletal ultrasound (MSUS) in different clinical settings. Accordingly, MSUS has been applied to a wide range of musculoskeletal problems including inflammatory and degenerative diseases, sport injuries, and regional pain syndromes both for clinical practice and research. In this report, the authors aimed to globally examine the publications on MSUS among different specialties, countries, and topics. Sixteen reviewers under the umbrella of the European Musculoskeletal Ultrasonography Society Group and the Ultrasound Study Group of International Society of Physical and Rehabilitation Medicine have evaluated approximately 15,000 publications on MSUS. The authors believe that the results of this comparative analysis may provide a holistic snapshot with regard to the utility of MSUS, not only for clinicians/academicians but also for the industry. Accordingly, while aiming to further increase their awareness, this article would possibly guide future investments as well.

Ultrasound imaging for sarcopenia, spasticity and painful muscle syndromes.

PURPOSE OF REVIEW: On the basis of its various advantages and the relevant awareness of physicians, ultrasound imaging has overwhelmingly taken its place in the scientific arena. This is true both from the side of daily clinical applications and also from the side of research. Yet, ultrasound provides real-time (diagnostic) imaging and (interventional) guidance for a wide spectrum of muscle disorders. In this regard, this review aims to discuss the potential/actual utility of ultrasound imaging in particular muscle disorders, that is, sarcopenia, spasticity and fibromyalgia/myofascial pain syndrome. RECENT FINDINGS: Due to the aging population worldwide and the importance of functionality in the older population, mounting interest has been given to the diagnosis and management of sarcopenia in the recent literature. Likewise, several articles started to report that ultrasound imaging can be used conveniently and effectively in the early diagnosis and quantification of sarcopenia.For spasticity, aside from ultrasound-guided botulinum toxin injections, intriguing attention has been paid to sonographic evaluation of muscle architecture, echogenicity and elasticity in the follow-up of these chronic conditions.As regards painful muscle syndromes, quantitative ultrasound techniques have been shown to detect statistically significant differences between healthy controls and patients with myofascial pain syndrome. SUMMARY: Ultrasound imaging seems to be a promising tool that indisputably deserves further research in the management of a wide range of muscle disorders.
