The phase image in radionuclide ventriculography shows the timing of ventricular contraction and is valuable in the detection of abnormalities induced by coronary artery disease. The image is usually interpreted subjectively, and in the present study a histogram of left ventricular phase values was used to make interpretation more objective. The left ventricular ejection fraction and the standa...

BACKGROUND Pulmonary hyperinflation has the potential for significant adverse effects on cardiovascular function in COPD. The aim of this study was to investigate the relationship between dynamic hyperinflation and cardiovascular response to maximal exercise in COPD patients. METHODS We studied 48 patients (16F; age 68 yrs ± 8; BMI 26 ± 4) with COPD. All patients performed spirometry, plethys...

BACKGROUND This study examined the effects of inhaled furosemide on the ventilatory and perceptual response to high-intensity constant-load cycle exercise in chronic obstructive pulmonary disease (COPD). METHODS In a randomised, double-blind, placebo-controlled, crossover study, 20 patients with COPD (mean (SD) forced expiratory volume in 1 s 45 (15)% predicted) received either nebulised furo...

Many studies have emphasized the importance of resistive exercise to maintain a healthy human body, particular in prevention of weakening of physical strength. Recently, some studies advocated that an application of vibration as a supplementary means in a regular training was effective in encouraging physical strength. Aim of the current study was, therefore, to identify if an application of vi...

conclusions the trunk stabilization exercises are more effective than conventional back care exercises in the rehabilitation of patients with chronic lbp. results the results of the study demonstrated significant improvements in abdominal muscle endurance and reduction in vas and modq score of both groups (p = 0.001). the trunk stabilization exercise group showed greater gains in abdominal musc...

The eVect of intensive exercise on disease activity in rheumatoid arthritis (RA) is an interesting one. Although we would not dispute that such exercise does indeed have a beneficial eVect on parameters of disease activity, we wish to propose an alternative hypothesis as to its mechanism. In particular, we would argue that the eVect of raised intraarticular pressure on synovial blood flow durin...
