To assess the relationship between aging and autonomic control of heart rate and blood pressure, cardiovascular reflex tests were performed in 70 healthy volunteers in the age range 25-71 years. R-R interval variation, heart rate change with deep breathing, 30/15 ratio and blood pressure response to standing appeared significantly declining with age. For(More)
The relationship between autonomic dysfunction and peripheral somatic neuropathy was investigated in uraemics. The battery of autonomic tests included R-R interval variation test, deep breathing, Valsalva manoeuvre, heart rate and blood pressure responses to standing, and sustained handgrip. Maximum conduction velocity along sensory and motor fibres of the(More)
Cardiac vagal reflexes were investigated in 19 dialysis patients, with the aim of verifying whether parathyroid hormone, proposed as an important uremic neurotoxin, plays a role in the development of uremic vagal neuropathy. The results indicate that parasympathetic control of heart function is frequently impaired in uremics. Plasma parathyroid hormone(More)
Thirty euthyroid patients hospitalized for completed stroke had serum thyroxine, triiodothyronine, thyroxine-binding globulin and thyroxine-binding prealbumin levels significantly decreased (p less than 0.01 to p less than 0.001) compared with 70 age- and sex-matched healthy controls. Admission serum thyroxine levels gave the best correlation with mortality(More)
Introduction: Physical exercise programs have been suggested to soften or reverse balance deficits and postural deviation. Objective: This study investigated the influence of a systematic aquatic exercise program on body balance. Method: Healthy young adult volunteers of both genders, aged 18–30 years were assessed. The experimental group (EG, n = 20) was(More)
