Advanced ambulatory systems that measure aspects of overt human behavior during normal daily life have become feasible, owing to developments in data recording and sensor technology. One such instrument is the Activity Monitor (AM). This paper provides a technical description of the AM and information about its validity and current applications. The AM is(More)
Physical whole-body vibration (WBV) exercises become available at various levels of intensity. In a first series of measurements, we investigated 3-dimensional platform accelerations of three different WBV devices without and with three volunteers of different weight (62, 81 and 100 kg) in squat position (150 degrees knee flexion). The devices tested were(More)
The aim of this study was to assess the energy cost and physical strain of daily activities in adolescents and young adults with myelomeningocele (MMC) compared with peers without a disability. Eighteen participants with MMC aged between 16 and 30 years (13 males, five females; mean age 21y 4mo [SD 4y 8mo]) and 18 age- and sex-matched non-disabled(More)
OBJECTIVE To assess the differences in daily physical activity between children with spastic diplegia and healthy schoolchildren, to determine whether special physical activity programs are needed in the population with cerebral palsy. DESIGN Cross-sectional design. SETTING Children's rehabilitation center Franciscusoord (day care center) and elementary(More)
We measured the extent of hypoactivity in adolescents and young adults with meningomyelocele with an activity monitor. The activity monitor is based on long-term ambulatory monitoring of signals from body-fixed accelerometers during everyday life and is aimed at the assessment of mobility-related activities. Measurements were performed during 2 consecutive(More)
OBJECTIVE We describe the occurrence and course of anterior pituitary dysfunction (PD) after aneurysmal subarachnoid haemorrhage (SAH), and identify clinical determinants for PD in patients with recent SAH. METHODS We prospectively collected demographic and clinical parameters of consecutive survivors of SAH and measured fasting state endocrine function(More)
OBJECTIVE Data on body fat and fitness in adolescents and young adults with meningomyelocele are scarce. The aim of this study was to assess body fat and fitness in this patient group. In addition, we explored whether the level of everyday physical activity is related to body fat and fitness. SUBJECTS AND METHODS Body fat (skinfold thickness), fitness(More)
This study assessed physical fitness and its relationships with everyday physical activity (PA) and fatigue in cerebral palsy (CP). Participants were 42 adults with ambulatory bilateral spastic CP (mean age 36.4 ± 5.8 years; 69% males; 81% with good gross motor functioning). Progressive maximal aerobic cycle tests determined VO(2peak) (L/min). Objective(More)
OBJECTIVE To determine the diagnostic value of a ghrelin test in the diagnosis of GH deficiency (GHD) shortly after aneurysmal subarachnoid hemorrhage (SAH). DESIGN Prospective single-center observational cohort study. METHODS A ghrelin test was assessed after the acute phase of SAH and a GH-releasing hormone (GHRH)-arginine test 6 months post SAH.(More)
BACKGROUND AND PURPOSE Because of dyspnea and fatigue, patients with congestive heart failure (CHF) may be restricted in the performance of normal everyday activities. The aim of this study was to obtain a preliminary indication of the level of activities associated with mobility during everyday life and between-day variance in activities in patients with(More)
