Effect of lung mechanics on mechanically assisted flows and volumes.
To correlate the air flows generated by mechanical insufflation-exsufflation as a function of pressure delivery in a lung model at two pulmonary compliance and three airway resistance settings. ⋯ Although mechanical insufflation-exsufflation pressures of 40 to -40 cm H2O are generally adequate for most patients with normal lung compliance and airway resistance, higher settings are often required when compliance decreases, by obesity or scoliosis, and possibly when airway resistance is increased.

Shoulder pain in hemiplegia: results from a national rehabilitation hospital in Turkey.
Shoulder pain is a common complication after stroke that can limit the patients' ability to reach their maximum functional potential and impede rehabilitation. The aim of our study was to examine the occurrence of hemiplegic shoulder pain in a group of Turkish patients and clarify contributing factors such as glenohumeral subluxation, reflex sympathetic dystrophy, tonus changes, motor functional level, limitation in shoulder range of motion, thalamic pain, neglect, and time since onset of hemiplegia. The effect of shoulder pain on the duration of rehabilitation stay was also identified. ⋯ These results indicate that shoulder pain is a frequent complication after stroke and that it may develop from a variety of factors. To prevent and alleviate shoulder pain, efforts should be directed toward proper positioning of the shoulder, range of motion activities, and the avoidance of immobilization.
