1 During gait, the trunk and neck are believed to play an important role in dissipating the transmission 2 of forces from the ground to the head. This attenuation process is important to ensure head control is 3 maintained. The aim of the current study was to assess the impact of externally restricting the motion of 4 the trunk and/or neck segments on acceleration patterns of the upper body and...

Work-related chronic neck pain is a growing disorder in the United States that accounts for approximately 60% of all occupational disabling injuries [1]. Neck pain is linked to continuous and excessive activation in the upper trapezius (UT) muscle [2]. An effective treatment for chronic neck pain may be to reduce activation in the UT through an inferior shift in the muscle activity to the middl...

neglected, untreated and delayed femur neck fractures are commonly encountered and the treatment dilemma arises especially when the patient is physiologically young and osteosynthesis is the preferred option. controversy exists in the current literature as the various head salvage surgeries like valgus subtrochanteric osteotomy, non-vascularized fibular bone grafting, muscle pedicle bone grafti...

Abstract Whiplash associated disorder (WAD) is a type of injury caused by rear‐end impacts. It painful long‐term the soft tissue in neck, which women suffer from 1.5 to 3 times more often compared men. Progress WAD research difficult, as (i) it occurs at loading level where muscle activity can no longer be neglected, (ii) characteristics play an essential role and (iii) there consensus on mecha...

OBJECTIVE To investigate neck muscle activity and postural control in patients with whiplash-associated disorder compared with healthy controls. DESIGN Cross-sectional study with convenience sampling. SUBJECTS Ten females with whiplash-associated disorder (age 37.7 years (21-58), neck pain > 2 years and neck disability index (NDI) > 10) and 10 healthy female controls (age 35.9 years (21-53)...

This study investigated changes in skeletal muscle cross-sectional area (CSA) evoked by fluid shifts that accompany short-term 6 degrees head-down tilt (HDT) or horizontal bed rest, the time course of the resolution of these changes after resumption of upright posture, and the effect of altered muscle CSA, in the absence of increased contractile activity, on proton transverse relaxation time (T...

abstract introduction: chronic neck pain is one of the most common problems among computer users. the aim of this research was evaluation of the effect of 8 weeks selected exercise therapy and self treatment with pamphlet programs on the strength and range of motion (rom) of the neck in the patients with chronic neck pain. methods: sixty-six patients with chronic neck pain (mean (±sd) age 39.19...

Near work is associated with increased activity in the neck and shoulder muscles, but the underlying mechanism is still unknown. This study was designed to determine whether a dynamic change in focus, alternating between a nearby and a more distant visual target, produces a direct parallel change in trapezius muscle activity. Fourteen healthy controls and 12 patients with a history of visual an...

The supplementary eye fields (SEF) are thought to enable higher-level aspects of oculomotor control. The goal of the present experiment was to learn more about the SEF's role in orienting, specifically by examining neck muscle recruitment evoked by stimulation of the SEF. Neck muscle activity was recorded from multiple muscles in two monkeys during SEF stimulation (100 μA, 150-300 ms, 300 Hz, w...
