We speculated that stroke volume would be higher and heart rate would be lower when the head and upper trunk were mainly upright in the Fowler's position. We therefore analyzed the effects of three trunk postures in Fowler's position on heart rate, blood pressure and circulatory volume. Heart rate (HR), blood pressure (BP), stroke volume (SV), cardiac output (Q), systemic vascular resistance (S...

the thyrocervical trunk most commonly arises from the upper portion of the first segment of the subclavian artery, close to the medial edge of the scalenus anterior muscle and after short distance is divided to the inferior thyroid, transverse cervical, and suprascapular artery. this study reports important variations in branches of the thyrocervical trunk in a singular female cadaver. on the r...

We have developed a method aiming at improving Functional Electrical Stimulation (FES) – assisted sit to stand transfer in people with paraplegia. The approach is based on the coordination of upper and lower parts of the body with final objective to reduce arm participation during the rising motion. The proposed approach is based on the observation of trunk acceleration during rising phase and ...

Sagittal trunk motion is accomplished through a coordination of pelvic rotation and lumbar spine flexion/extension. As trunk range of motion in healthy subjects is not fundamentally different to persons with lowback pain (LBP), other means of discriminating the two populations must be used. Research suggests that lumbar-pelvic (LP) coordination could be a potential diagnostic metric for LBP. Th...

This study aimed to investigate the inter-limb coordination pattern and the stability, intensity, and complexity of the trunk and limbs motions in human crawling under different speeds. Thirty healthy human adults finished hands-knees crawling trials on a treadmill at six different speeds (from 1 km/h to 2.5 km/h). A home-made multi-channel acquisition system consisting of five 3-axis accelerom...

Lateral cord and median nerve are associated with variations. We observed concurrent variations in the formation of lateral cord and median nerve in thirty two formalin fixed cadavers. In 29.6% upper limbs Lateral cord was formed by anterior division of upper trunk only. In 21.8% of these cases the anterior division of middle trunk formed two additional roots for the median nerve and in 7.8% ca...

Most transhumeral amputees report that their prosthetic device lacks functionality, citing the control strategy as a major limitation. Indeed, they are required to control several degrees of freedom with muscle groups primarily used for elbow actuation. As a result, most of them choose to have a one-degree-of-freedom myoelectric hand for grasping objects, a myoelectric wrist for pronation/supin...

OBJECTIVE To examine the effects of experimentally induced pain and fear of pain on trunk coordination and erector spinae EMG activity during gait. DESIGN In 12 healthy subjects, hypertonic saline (acute pain) and isotonic saline (fear of pain) were injected into erector spinae muscle, and unpredictable electric shocks (fear of impending pain) were presented during treadmill walking at differ...
