The prevalence of low back disorders is dramatically high in viticulture. Field measurements that objectively quantify work exposure can provide information on the relationship between the adopted trunk postures and low back pain. The purposes of the present study were three-fold (1) to carry out a kinematics analysis of vineyard-workers’ pruning activity by extracting the duration of bending a...

BACKGROUND AND PURPOSE In prehension tasks with objects placed within arm's reach, patients with hemiparesis caused by stroke use excessive trunk movement to compensate for arm motor impairments. Compensatory trunk movements may improve motor function in the short term but may limit arm recovery in the long term. Previous studies showed that restriction of trunk movements during reach-to-grasp ...

The effects of aging on lower trunk (trunk-low-back joint-pelvis) coordination and energy transfer during locomotion has received little attention; consequently, there are scant biomechanical data available for comparison with patient populations whose upper body movements may be impaired by orthopaedic or neurologic disorders. To address this problem, we analyzed gait data from a cross-section...

OBJECTIVE To determine whether trunk position sense is impaired in people with poststroke hemiparesis. BACKGROUND Good trunk stability is essential for balance and extremity use during daily functional activities and higher level tasks. Dynamic stability of the trunk requires adequate flexibility, muscle strength, neural control, and proprioception. While deficits of trunk muscle strength hav...

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed to investigate the relation of the trunk and hip kinematics with the peak knee abduction angle during single-leg landing among preadolescent female soccer players. Methods: Thirty-s...

Patterning of the Drosophila embryonic termini is achieved by localized activation of the Torso receptor by the growth factor Trunk. Governing this event is the perforin-like protein Torso-like, which is localized to the extracellular space at the embryo poles and has long been proposed to control localized proteolytic activation of Trunk. However, a protease involved in terminal patterning rem...

Figure 1 Kneeling trunk rotation (a) start position (b) final position. Sports such as tennis, golf, baseball, and hockey each involve a tremendous amount of trunk rotation. It is not just striking sports, but also throwing, kicking, running, swimming, skiing, etcwhichall require yourbody to rotate throughyour core. In order to transmit forces from your bigger, stronger leg muscles to your arms...

queueing model. We define a new concept of trunk as a group of voice traffic with identical destination and DSCP. It is assumed that at least one trunk should be established between the ingress router and corresponding egress router. Each trunk has a different voice traffic arrival rate and mean service timc. We assume that there are P types of queues. In a queue of typc lc (k = I, 2, ..., P), ...
