Purpose: Measurement of muscle mass is paramount in the screening and diagnosis of sarcopenia. Besides muscle quantity however, also quality assessment is important. Ultrasonography (US) has the advantage over dual-energy X-ray absorptiometry (DEXA) and bio-impedance analysis (BIA) to give both quantitative …

The performance of neural electrodes in physiological fluid, especially in chronic use, is critical for the success of functional electrical stimulation devices. Tips of the Utah electrode arrays (UEAs) were coated with sputtered iridium oxide film (SIROF) and activated iridium oxide film (AIROF) to …

BACKGROUND: The mixing ability test (MAT) as an outcome measure of masticatory performance is largely used in studies with adults, but not yet with children. OBJECTIVE: This study aimed to test the construct validity and the test-retest reliability of the MAT in children with spastic cerebral palsy (CP) …

Rationale: Sarcopenia is a major problem and is common in community-dwelling elderly. In daily practice, there is need for low cost and easily assessable measurement tools to assess depletion of skeletal muscle (SM) mass, for example as one of the indicators of sarcopenia. Bio-electrical impedance analysis …

Rationale: Although ultrasound has been reported as valid and reliable tool to assess muscle size in older adults1, little is known about intra-rater reliability (intra-RR) and inter-rater reliability (inter-RR) of BodyMetrix in specific to assess small muscles. Therefore, in this study we aimed to assess …

This review evaluates the reliability and validity of ultrasound to quantify muscles in older adults. The databases PubMed, Cochrane, and Cumulative Index to Nursing and Allied Health Literature were systematically searched for studies. In 17 studies, the reliability (n = 13) and validity (n = 8) of …

Validity and reliability of a hand held ultrasound device to measure muscle size

The use of musculoskeletal Ultrasound (MSU) has been increasing amongst physiotherapist. The efficacy of MSU as a biofeedback training tool diaphragm muscle has not yet been evaluated even though it is a muscle known to be vital in contributing to spinal stability. Before assessing the effectiveness …

Poor mastication has been widely associated with cognitive impairments in elderly people. Ultrasound technology (US) and bite force measuring devices are both used to assess the masticatory muscles, providing an indication of their condition. Objective: The purpose of this study was to assess masseter …

This review describes the exact standard reference values for measurements of the supraspinatus tendon and muscle obtained by muskuloskeletal ultrasound, magentic resonance imaging and cadaveric studies.
