Creating a Standardized Program To Resistance Train The Muscles Of The Head and Neck
… a specific protocol to strengthen the head and neck muscles exists and no systematic study of increase in neck musculature attributed to such a protocol is documented. Thus, this study will produce a standardized methodology for the reduction of concussive and subconcussive forces, laying the …

Low-frequency activity in the primate superior colliculus activates a head turning synergy: evidence using neck EMG recordings
… and electromyographic (EMG) activity of dorsal neck muscles from three rhesus monkeys performing a gap-saccade paradigm with different levels of reward expectancy. As reward expectancy increased, low-frequency dSC activity increased and EMG activity from the contralateral obliquus capitis …

Analysis of electromyograph (EMG) for controlling wheelchair motion
… Spinal Cord Injury (SCI), the EMG signal from neck has been chose to trigger the wheelchair. The EMG signals are obtained using disposable electrode from neck muscles which are Sternocleidomastoid and Trapezius muscles, with different direction. For the acquisition of SEMG signal MyDAQ is used. …

Superficial cervical muscle activation in chronic neck pain
Chronic neck pain can occur in a proportion of individuals who have suffered a whiplash injury and also in individuals that have not experienced a trauma to the neck. The mechanisms that cause chronic pain are unclear, and whether they differ in traumatic or non-traumatic onset is …

Vestibular Evoked Myogenic Potentials : physiology, variability, and statistical characteristics
… recorded from the skin overlying skeletal muscles of the head and neck in response to high-intensity acoustic stimuli. VEMPs have been observed in stimulus locked averages of the electromyogram in a majority of human subjects, and are thought to originate in the otolith organs of the inner …

Differences between adult and pediatric neck muscle stress due muscle recruitment patterns
… is appropriate. The muscle response of the neck muscles in 50th percentile adult male was compared to the neck muscle response of the 10-year-old boy under static and dynamic loading conditions. Magnetic resonance imaging was used to measure the muscle length, moment arm and cross-sectional …

Effects of altered sensory input from the neck on cerebellar function, body schema and sensorimotor integration
Neck muscles have a high density of muscle spindle afferents and their input is critical for formulating the perception of head position relative to the body. Chronic alterations in afferent input from the neck may be studied in individuals with subclinical neck pain (SCNP), defined as non-severe …

Impact of neck muscle fatigue on upper limb sensorimotor integration
Neck muscles have a high density of sensory receptors which project to the central nervous system, and have important role in sensory motor integration (SMI). The cerebellum is important for SMI and it is known to undergo neuroplastic changes in response to performing a novel motor acquisition …

Cervical influence on dizziness and orientation
… motion was examined in three dimensions in 120 neck-healthy subjects. Movement patterns of combined primary and coupled movements and the influence of age, gender and body mass index on these movements were investigated. Coupled movements are a natural part of cervical motion together with …

A Computer Simulation Model of The Human Head-Neck Musculoskeletal System
… biomechanical model of the human head-neck system that could be used to simulate neck movements under muscle control. This model can further be modified to enable input from an external stimulus, such as EMG data.</p> <p><strong>Summary of background data</strong>. Utilizing computer …

Effect of vibration exposure duration on discomfort
… to vibration produced discomfort mainly at the neck.<br/>Because discomfort was mainly felt at the neck and that the SDTD depended on the frequency, it was hypothesised that the type of neck muscle activity produced during exposure to vibration depends on the frequency. Neck muscle activity was …

Traumatic brain injuries and older adults: The implications of neck strength, muscle activation, and range of motion
… TBIs in older adults may be related to neck musculature and function. Yet, these risk factors have received less scientific scrutiny in older adults. Thus, the current project quantified isometric neck strength, active and passive range of motion, and neck muscle activation latency in …

The effects of changing head position and posture on head tremor in individuals with essential tremor involving the head
… and vision conditions (eyes open and closed). Neck muscle activity was recorded from three muscles bilaterally (trapezius, sternocleidomastoid, splenius capitis). Three-dimensional head and thorax positions were recorded using an Optotrak system, and head angular velocity with respect to thorax …

Screening for Torticollis and Plagiocephaly: The Role of the Pediatrician
<p>The purpose of this study was to examine the effects of providing a standardized screening examination to a group of attending and resident physicians on the rate of torticollis and plagiocephaly diagnoses, the age at time of diagnosis, and the attitudes and practice patterns of the physicians. …
