Background & Aims: Scoliosis is linked with asymmetrical compression loads induced by trunk muscles and external loads. The objective of this study was to measure the electrical activity of bilateral erector spinae muscles during the rest in the standing, sitting and lying positions. Materials & Methods: Ten patients with double curvature (right thoracic and left lumbar) scoliosis...
Background and Objectives: In recent years, due to the rapid growth of metropolitan cities and the shortage of urban public transport means, including urban bus transportation, many people are forced to travel in a standing position when using these vehicles. This situation may cause pain and discomfort and non-collision injuries for passengers. The purpose of this study was ergonomic assessmen...
The authors aimed to investigate the relation between components of adult height (leg and trunk length) and atherosclerosis in middle age, using data from 12,254 participants (aged 44-65 years) in the Atherosclerosis Risk in Communities (ARIC) Study. Intimal-medial thickness (IMT) as measured by B-mode ultrasound was the outcome, and exposures were trunk and leg lengths as estimated (using sitt...
The contribution of venous return to the increase in anaerobic threshold (AT) in patients with acute myocardial infarction (AMI) was investigated. Twenty-seven patients with uncomplicated AMI underwent supine and sitting cardiopulmonary exercise testing, and 10 out of these 27 patients performed constant-workload tests in which cardiac output before and after a phase II program was measured. Da...
Vital capacity, frequently measured clinically as an index of pulmonary function, gives useful information about the strength of respiratory muscles and other aspects of lung functions. It is generally noted in sitting position. As in the supine position, respiratory excursions of diaphragm is highest in normal breathing, this study was planned to note whether there occurred any alteration in v...
The purpose of this study was to ascertain the importance of learning a motor task in a sitting position and its influence on gait. Thirty-one healthy subjects, divided into three groups, were asked to learn a synchronous heel-up-heel-down rhythm task in a sitting position and to reproduce the rhythm during their gait cycle on three separate occasions over a three-day period. This study provide...
