BACKGROUND We aimed to assess the measurement properties and the minimal important difference (MID) of the 1-min sit-to-stand (STS) test in cystic fibrosis (CF). METHODS Patients with CF were tested during a pulmonary rehabilitation program. Five STS tests were performed during the program; two tests at the beginning (STS0 and STS1) and three tests at the end (STS2a-2c). Exercise capacity, pu...

Developing software for stand-alone environments requires the availability of an interactive test support at an early stage of work. But rough conditions close to hardware force the test support to be content with minimal assistance by infrastructure. Sash (stand-alone shell) is the test support for developing the CHEOPS-Kernel and is presented in this paper. Sash is based on a yacc-grammar and...

An opto-electronic seed spacing evaluation system that measured time intervals between seeds and detected frontto-back location of seed drop events relative to the planter was used to rapidly determine planter seed spacing uniformity in the laboratory. The seed detection sensor for the opto-electronic system consisted of a rectangular photogate with 24 phototransistors receiving light beams fro...

Exercise tests are important to characterise chronic obstructive pulmonary disease patients and predict their prognosis, but are often not available outside of rehabilitation or research settings. Our aim was to assess the predictive performance of the sit-to-stand and handgrip strength tests. The prospective cohort study in Dutch and Swiss primary care settings included a broad spectrum of pat...

Recent studies have shown that swimming is of relatively low asthmogenicity, even under conditions of high respiratory heat (and/or water) loss (RHL). It has been suggested that the horizontal body position may contribute to swimming's low asthmogenicity. We studied the effects of upright and prone body postures on pulmonary function following exercise (EIA) and after nonexercise hyperventilati...
