[Purpose] The purpose of this study was to examine the effects of interferential current therapy on the shoulder muscles of subjects with forward head posture. [Subjects and Methods] Thirty volunteers (15 forward head posture, 15 control) participated in this study. Interferential current therapy treatment was conducted for 10 min, three times per week, for 3 weeks on both the upper trapezius a...

We have identified dimeric kinesin mutants that become stalled on the microtubule after one ATP turnover, unable to bind and hydrolyze ATP at their second site. We have used these mutants to determine the regulatory signal that allows ATP to bind to the forward head, such that processive movement can continue. The results show that phosphate release occurs from the rearward head before detachme...

background: office workers spend a long period of time behind a computer during working hours. the relation between the posture of sitting during work with computer and neck pain is still debatable. even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the fhp (forward head posture) has not always been associated ...

When placed on a temperature gradient, a Drosophila larva navigates away from excessive cold or heat by regulating the size, frequency, and direction of reorientation maneuvers between successive periods of forward movement. Forward movement is driven by peristalsis waves that travel from tail to head. During each reorientation maneuver, the larva pauses and sweeps its head from side to side un...

Elongation factor-G-catalyzed translocation of mRNA and tRNAs during protein synthesis involves large-scale conformational changes in the ribosome. Formation of hybrid-state intermediates is coupled to counterclockwise (forward) rotation of the body of the 30S subunit. Recent structural studies implicate intrasubunit rotation of the 30S head in translocation. Here, we observe rotation of the he...

OBJECTIVES To examine the correction of posture, increase in strength and decrease in shoulder pain and dysfunction in varsity swimmers. DESIGN AND SETTING Randomised clinical trial. PARTICIPANTS Twenty-eight National Collegiate Athletic Association division I varsity swimmers. MEASUREMENTS Two testing sessions were conducted before and after an 8-week time period. Posture, strength and s...
