The purpose of this study was to assess trunk muscle fatigue in seated handicraft tasks using surface electromyography (sEMG) and visual analogue scale (VAS) ratings for trunk discomfort, and to assess the relationship of these responses. Twenty-three participants were randomly assigned to assumed crossed-leg and heel sitting postures for 30 min. Normalised median frequency (NMF) slopes for lum...
Background and purpose: Airway assessment is very important in anesthesia. The aim of this study was to determine the diagnostic value of Mallampati test indicators in supine and sitting positions with and without phonation in anesthesia candidate patients. Materials and methods: This cross-sectional descriptive study (diagnostic approach) was done in 200 adult patients ≥16 years, undergoing s...
[Purpose] To clarify how a novel dynamic cushion affects the leg edema evoked by wheelchair sitting, we measured the changes in leg volume induced during wheelchair sitting with the dynamic air cushion or a static cushion. [Subjects and Methods] Nine healthy male subjects participated in this study. Leg edema during wheelchair sitting was evaluated with strain gauge plethysmography (the gauge w...
Because acetabulum is a part of hip joint, its fracture is important. At first, it is a weight bearing joint and it is involved in approximately all movements of body. In daily living, it must tolerate about 5-7 times body weight. For example, in the position of one leg stance about 3.5 times body weight is transmitted to hip joint. Even in sitting position and also in supine position and strai...
Introduction: In hypertensive patients M position (sitting, right arm at the level of heart and both plantar surface of foots on the floor) is the standard position for measurment of blood pressure since it reveals the “true” pressure. Materials and Methods: It is a quaziexperimental study that compares effect of different positions of limbs on blood pressure of hypertensive patients. The sampl...
Which physiological mechanism is responsible for the increase in blood pressure during leg crossing?
OBJECTIVE To determine which physiological mechanism is responsible for the blood pressure increase during leg crossing at knee-level in the sitting position. METHODS Finger blood pressure was measured with the Finometer in 102 participants (47 men) before and during leg crossing: 24 treated hypertensive patients, 50 diabetic individuals (25 with and 25 without antihypertensive medication) an...
The aim of this study was to investigate the infl uence of diff erent positions on stretch refl ex activity of knee fl exors and extensors measured by surface electromyography in poststroke patients with spasticity and its expression in the Ashworth scale. Nineteen poststroke patients with lower-limb spasticity participated in this crossover trial, during which stretch refl ex activity was asse...
OBJECTIVE To investigate the influence of different positions on stretch reflex activity of knee flexors and extensors measured by electromyography in poststroke patients with spasticity and its expression in the Ashworth Scale. DESIGN Crossover trial with randomized order of positioning. SETTING Outpatient rehabilitation center in the Netherlands. PARTICIPANTS Poststroke patients (N = 19...
