[Purpose] Sitting position is the dominant position for a professional pianist. There are many static and dynamic forces which affect musculoskeletal system during sitting. In prolonged sitting, these forces are harmful. The aim of this study was to compare pianists' back extensor muscles activity during playing piano while sitting on a regular piano bench and a chair with back rest. [Subjects ...

Graph theory provides many metrics of complex network organization that can be applied to analysis of brain networks derived from neuroimaging data. Here we investigated the test-retest reliability of graph metrics of functional networks derived from magnetoencephalography (MEG) data recorded in two sessions from 16 healthy volunteers who were studied at rest and during performance of the n-bac...

OBJECTIVE To compare the thyroid hormonal responses to high-intensity interval exercise (IE) and steady-state endurance exercise (SEE) in highly trained males (n=15). DESIGN The IE session consisted of repeated periods of 90-seconds treadmill running at 100-110% VO(2max) and 90-seconds active recovery at 40% VO(2max) for 42-47 minutes. The SEE session was a 45-minute run at 60-65% VO(2max). T...

BACKGROUND The opioid remifentanil induces a decrease of vestibulo-ocular reflex function, which has been associated with nausea and vomiting when the subjects are moved. The study investigates in healthy female volunteers if immobility after remifentanil administration protects from nausea and vomiting. METHODS In volunteers, a standardized movement intervention (a manually applied head-trun...

the main aim of the present study was to examine the effect of field-independent and field-dependent cognitive styles on learning an aiming task in closed and open environments based on fuzzy and classic logics. 60 male students with an age range of 16-17 were assigned to four groups (each group 15 subjects): field-independent with classic approach, field-dependent with classic approach, field-...

BACKGROUND Active inversion and eversion ankle range of motion (ROM) is widely used to evaluate treatment effect, however the error associated with the available measurement protocols is unknown. This study aimed to establish the reliability of goniometry as used in clinical practice. METHODS 30 subjects (60 ankles) with a wide variety of ankle conditions participated in this study. Three obs...
