The aim of research was to assess exercise-induced changes in mechanics of hearts isolated from rats, as well as time-course of those changes. Wistar rats (n = 42) were divided into control, moderately trained (swimming 1 hour, 5 days a week for 9 or 12 weeks) and strenuously trained (swimming 2, 3 and 4 times a day for an hour in weeks 10, 11 and 12, respectively) groups. After sacrificing, hearts (weight: 1480.82 ± 145.38 mg) were isolated and perfused on a Langendorff apparatus. Coronary perfusion pressure (CPP) was gradually increased (from 40 to 120 cm H2O) in order to establish coronary autoregulation. Parameters of cardiac contractility were recorded: maximum and minimum rate of change of pressure in the left ventricle (dp/dt max and dp/dt min), systolic and diastolic left ventricular pressure (SLVP and DLVP), heart rate (HR) and coronary flow (CF). Nine weeks of moderate exercise induced slight depression of coronary function (decrease of dp/dt max, dp/dt min, SLVP and DLVP)...

Although intensively investigated, the procedures for assessment and monitoring of scoliosis are still a subject of controversies. The aim of this study was to assess validity and reliability of a number of physiotherapeutic measurements that could be used for clinical monitoring of scoliosis. Fifteen healthy (symmetric) subjects were subjected to a set of measurements two times, by two experienced and two inexperienced physiotherapists. Intra-observer and inter-observer reliability of measurements were determined. Following measurements were performed: body height and weight, chest girth in inspirium and expirium, the length of legs, the spine translation, the lateral pelvic tilt, the equality of the shoulders, position of scapulas, the equality of stature triangles, the rib hump, the existence of m. iliopsoas contracture, Fröhner index, the size of lumbar lordosis and the angle of trunk rotation.RESULTS: Intraclass correlation coefficient was high (> 0.8) for majority of measur...

The purpose of the study was to assess the effects of hyperbaric oxygen (HBO2) therapy on prosthetic rehabilitation of patients with unilateral lower limb amputation. Narang's scale,the Locomotor Capabilities Index and the two-minute walk test were used to assess functional abilities of amputees on the admission and on discharge from hospital. We also kept records of some clinical parameters whose improvement enables better mobility of patients: thigh and lower leg girth, strength of amputation stump, existence of amputation stump contracture, existence of some other complications on amputation stump, blood oxygenation and pulse palpation. Our results show that hyperbaric oxygenation accelerates prosthetic rehabilitation of lower limb amputees. HBO2-treated patients were discharged from the hospital faster than the controls (hospitalized for 133.2 +/- 54.87 days vs. 158.36 +/- 53.05 days), they had improved arterial Hb saturation (97.40 +/- 3.51% vs. 94.74 +/- 3.28 %) and pulse ...
