Kinematic quantification of gait asymmetry in patients with peroneal nerve palsy based on bilateral cyclograms.

Nowadays, bipedal walking is undergoing extensive study. Several methods can be used in physiotherapeutic research for identifying defects in bipedal walking as a result of pathology of the musculoskeletal or nervous system. Our work focuses on studying asymmetry of walking based on synchronized bilateral knee-knee cyclograms. Participants presenting with peroneal nerve palsy and foot drop were included in the study. The bilateral cyclograms, also called angle-angle diagrams, were created to quantify gait asymmetry before and immediately after application of a brace. In order to quantify the asymmetry of human walking, we have described and tested the application of the method based on the inclination angle of the synchronized bilateral cyclograms. The symmetry index (SI) was used as a comparative method to evaluate the symmetry of bipedal walking. The method based on the orientation of the cyclograms can be used as an additional method for determining the gait asymmetry. The new technique has never been applied before to study the gait asymmetry in patients with peroneal nerve palsy or patients with leg brace.

Quantitative ballistocardiography (Q-BCG) for measurement of cardiovascular dynamics.

In the seventies of the past century ballistocardiography had been thought to be obsolete in cardiology for impossibility of objective calibration. In the present work the quantitative ballistocardiography (Q-BCG) for measurement of systolic force (F) and minute cardiac force (MF) in sitting subject was described. The new principle of piezoelectric transducer enabled to register the force caused by the heart and blood movement, which was not measured before. The calibration proved that the action of the force on the transducer was expressed quantitatively without the amplitude-, time-, and phase deformation. The close relationship of skeletal muscle force and F was proved. The F and MF changed under different physiological conditions (age, partial pressure of oxygen, body weight, skeletal muscle force). It was shown that the systolic force (F) and minute cardiac force (MF) are the physiological parameters neurohumorally regulated similarly as the heart rate or systolic volume.

[Chronic torsion of an ectopic spleen in the differential diagnosis of abdominal pain in a child. Case report]. / Chronická torze ektopické sleziny v diferenciální diagnostice bolestí bricha u dítete. Kazuistika.

Torsion of the spleen occurs in children as a rule in combination with ectopy of this organ. It is found in cca one half of the affected children. Abdominal pain is always an associated symptoms. Its intensity depends on other factors such as the degree of torsion, its duration, the pathophysiology of the process etc. The final prognosis can be usually made only during laparotomy. With regard to the relatively rare incidence of this disease, the authors submit the case of a patient operated in their department.
