Background The ability to perform activities of daily living (ADL) as a component of participation is one of the factors that contribute to the quality of life. The ability to perform ADL for persons experiencing severe/profound intellectual disability (ID) may be reduced due to their cognitive and physical …

BACKGROUND: Exercise capacity, muscle function, and physical activity levels remain reduced in recipients of lung transplantation. Factors associated with this deficiency in functional exercise capacity have not been studied longitudinally. OBJECTIVE: The study aims were to analyze the longitudinal change …

Background: Activity trackers can potentially stimulate users to increase their physical activity behavior. The aim of this study was to examine the reliability and validity of ten consumer activity trackers for measuring step count in both laboratory and free-living conditions. Method: Healthy adult …

Wat is het lineare model? Hoe kunnen we dit model schatten en wat komt daar allemaal bij kijken? Hoe kun je aan model selectie doen?

Hier wordt de lezer systematische geleid van de t-toets, ANOVA, ANCOVA naar Mixed Model. Elk model wordt met een analyse van gegevens geillustreerd.

The aim of this study is to examine the inter-device reliability of an activity tracker on three different levels of aggregation: minute, hour and day.

BACKGROUND: Muscle force is important for daily life and sports and can be measured with a handheld dynamometer. Reference values are employed to quantify a subject's muscle force. It is not unambiguous whether reference values can be generalized to other populations. Objectives in this study were; first …

Bioelectrical impedance analysis (BIA) may be used to assess fat free mass (FFM) with reasonable validity based on mean-level comparisons, but differences between BIA and DXA may vary by about 4 kg in an individual patient. These results require confirmation in a larger sample of HNC (Head and neck cancer) …

BACKGROUND: The predictive validity of the Low Back Pain Perception Scale is determined in two studies in general practice and showed sufficient discriminative ability, although the psychometric properties of the scale have never been established until now. OBJECTIVE: To determine the reliability and …

Purpose of this longitudinal observational study was to (i) examine the change of daily physical activity in 28 adult kidney transplant recipients over the first 12 months following transplantation; and (ii) to examine the change in metabolic characteristics and renal function. Accelerometer-based daily …
