PURPOSE To systematically review the methodologic quality of, and summarize the evidence from trials examining the effectiveness of physical exercise in improving the level of physical functioning and psychological well-being of cancer patients during and after medical treatment. METHODS Thirty-four randomized clinical trials (RCTs) and controlled(More)
BACKGROUND Muscle power assessed by isokinetic dynamometers has the potential for playing an important role in investigating functional status in older subjects. Researchers and clinicians are interested in the reliability of isokinetic test protocols for the confidential assessment of status, as this affects the interpretation of the results of an(More)
OBJECTIVE To systematically review educational or psychoeducational interventions for patients with rheumatoid arthritis focusing on long-term effects, especially health status. METHODS Two independent reviewers appraised the methodologic quality of the included randomized controlled trials, published between 1980 and July 2002. RESULTS Validity scores(More)
Patients who undergo hematopoietic SCT (HSCT) often experience physical and psychological problems, even long after treatment has been completed. This study was performed to evaluate the effects of a 12-week outpatient physical exercise (PE) program, incorporating aerobic and strength exercises, as compared with a usual care control condition on patients’(More)
BACKGROUND There is increasing evidence for the beneficial effects of exercise training in stroke survivors. In order to reach the desired training effects, exercise training principles must be considered as this ensures the prescription of adequate exercises at an adequate dose. Moreover, exercise training interventions must be designed in a way that(More)
The use of wearable motion sensing technology offers important advantages over conventional methods for obtaining measures of physical activity and/or physical functioning in individuals with chronic diseases. This review aims to identify the actual state of applying wearable systems for monitoring mobility-related activity in individuals with chronic(More)
Our aim was to determine several indexes of reproducibility for strength measurements with a hand-held pull-gauge dynamometer (MFB50K) in cancer patients. Two independent testers performed repeated measurements of maximal isometric elbow and knee strength. The measurements were gathered in a convenience sample of 40 patients (27 men, age 20–72 years) with(More)
BACKGROUND Hand-held dynamometry is a portable and inexpensive method to quantify muscle strength. To determine if muscle strength has changed, an examiner must know what part of the difference between a patient's pre-treatment and post-treatment measurements is attributable to real change, and what part is due to measurement error. This study aimed to(More)
BACKGROUND Previous studies have shown the beneficial effects of aerobic exercise in chronic stroke. Most motor and functional recovery occurs in the first months after stroke. Improving cardiovascular capacity may have potential to precipitate recovery during early stroke rehabilitation. Currently, little is known about the effects of early cardiovascular(More)
BACKGROUND Use of exergames can complement conventional therapy and increase the amount and intensity of visuospatial neglect (VSN) training. A series of 9 exergames-games based on therapeutic principles-aimed at improving exploration of the neglected space for patients with VSN symptoms poststroke was developed and tested for its feasibility.
