Qualitative muscle mass index as a predictor of skeletal muscle function deficit in Asian older adults.

Aim: The present cross-sectional study was carried out among community-dwelling Koreans to determine the validity of various muscle mass indices and to propose more clinically relevant diagnostic criteria.

Methods: This study measured the anthropometrics, body composition and physical capability of 415 older Koreans. Skeletal muscle indices were calculated by dividing appendicular lean mass by height or weight.

A brief history of ultrasound in rheumatology: where we are now.

Ultrasound is gradually becoming established as an indispensable tool within the rheumatology clinical setting. Falling costs, improved educational opportunities, standardisation and developments in therapeutics have all led to the greater acceptability of the technique. This review will highlight how far ultrasound has come in a relatively short period of time by providing an overview of how it is being applied in rheumatology today.

Value of ultrasound in rheumatologic diseases.

The use of musculoskeletal ultrasound in rheumatology clinical practice has rapidly increased over the past decade. Ultrasound has enabled rheumatologists to diagnose, prognosticate and monitor disease outcome. Although international standardization remains a concern still, the use of ultrasound in rheumatology is expected to grow further as costs fall and the opportunity to train in the technique improves.

The evolution of ultrasound in rheumatology.

Musculoskeletal ultrasound is a powerful tool not only for evaluating joint and related structures but also for assessing disease activity. Ultrasound in rheumatology has rapidly evolved and been incorporated into routine clinical practice over the past decade. Moreover, technological development of equipment has made it more accessible for rheumatologists.
