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 research in this dissertation aims to investigate the acquisition of students’ science skills in grades 5 and 6 of primary education in the Netherlands. In most primary science classes, science skills are mainly taught by way of conducting investigations. However, prior research indicates that explicit …

Background: Follow-up of stroke survivors is important to objectify activity limitations and/or participations restrictions. Responsive measurement tools are needed with a low burden for professional and patient. Aim: To examine the concurrent validity, floor and ceiling effects and responsiveness of …

OBJECTIVES: The aim of this study was to improve medication safety for children; it is important to quantify the occurrence of preventable medication errors (MEs). A trigger tool may be an effective and time-saving strategy, but its measurement performance is unclear. Therefore, we aimed to estimate …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …

Background: This follow-up study investigated the year-round effects of a four-week randomized controlled trial using different types of feedback on employees’ physical activity, including a need-supportive coach intervention. Methods: Participants (n=227) were randomly assigned to a Minimal Intervention …

In the literature, illness perceptions have been reported to be important psychological factors associated with pain intensity and physical function in individuals with musculoskeletal pain. The objective of this study was to assess the relationship of illness perceptions with pain intensity and physical …

This research is done on behalf of the company Fudura, which is, as a commercially operating organisation, part of the Enexis Group. Fudura is a nationwide organisation operating on the Dutch energy market, especially in the provinces of Groningen, Drenthe, Overijssel, Noord-Brabant, and Limburg. As …

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 …
