OBJECTIVES It has been difficult to monitor the pelvic position during actual daily life. However, recent developments in wearable device technologies, such as the LUMOback device, provide the possibility to evaluate habitual pelvic posture and time spent sitting during daily life. The current study aimed (1) to investigate test-retest reliability for habitual pelvic posture and time spent sitt...

BACKGROUND Many studies have assessed Yoga practices using instruments such as AcuGraph, which measures conductances at Jing-Well points of acupuncture meridians. Such studies find that participation in Yoga programs ranging from a weekend to many months systematically increases subtle energy. Here, we report comparison of Jing-Well point conductances before and after sitting in Lotus Posture w...

PURPOSE To determine the effect of a 45° reclining sitting posture on swallowing in patients with dysphagia. MATERIALS AND METHODS Thirty-four patients with dysphagia were evaluated. Videofluoroscopic swallowing study was performed for each patient in 90° upright and in 45° reclining sitting posture. Patients swallowed 5 types of boluses twice: sequentially 2 mL thin liquid, 5 mL thin liquid,...

OBJECTIVES To investigate the effect of different induced head-neck-jaw postures on head-neck relocation error among healthy subjects. METHODS 30 healthy adult male subjects participated in this study. Cervicocephalic kinesthetic sense was measured while standing, habitual sitting, habitual sitting with clenched jaw and habitual sitting with forward head posture during right rotation, left ro...

In nowdays digitalized and industrialized society, sitting is the most frequent posture at work, at school and also during the leisure time (surfing on the internet, gaming...). Because of gravity, the erect posture is associated with an increase of the lumbar intra-discal pressure, which has first been evidenced in the in vivo measurements of Nachemson [1-3]. In these studies, the authors depi...

In order to understand the complex autonomic adjustments that occur during the psychological challenges of normal daily life, autonomic responses to psychological stress were studied by evaluating the effects of body posture on various indices of sympathetic and parasympathetic regulation during performance of a psychological task. Twelve male subjects were studied in various postures (supine, ...

Few studies quantify spinal posture behaviour at both the thoracolumbar and lumbar spinal regions. This study compared spontaneous spinal posture in 50 asymptomatic participants (21 males) during three conditions: 10-min computer task in sitting (participants naïve to the measure), during their perceived 'correct' sitting posture, and standing. Three-dimensional optical tracking quantified surf...

Baseline airway geometry is thought to be an important determinant of the airway response to challenge; this geometry is altered by changing posture. The effect of changes in posture on airway calibre, midtidal lung volume, and the airway response to inhaled histamine was studied in eight healthy subjects (four female; mean (SD) age 29.8 (5.1) years, FEV1 3.54 (0.65) 1). Each subject was studie...

OBJECTIVE To evaluate the cardiopulmonary effects of open sea scuba air diving to 39 m (30 minutes bottom time) with standard decompression. To account for possible gravity dependent effects of venous gas bubbles, the variables were measured in different post-dive body postures and compared with the baseline values before the dive in the same posture. METHODS Eight male divers conducted two s...
