Background: Heroin is an extremely addictive narcotic drug derived from morphine. Its continued use requires increased amounts of the drug to achieve the same effect, resulting in tolerance and addiction. This study was done in order to determine the prevalence of musculoskeletal pain and forward head posture among heroin users during their withdrawal. Methods: This research was a cross-section...

Percutaneous electrical vestibular stimulation evokes reflexive responses in appendicular muscles that are suppressed during tasks in which the muscles are not contributing to balance control. In neck muscles, which stabilize the head on the torso and in space, it is unclear whether similar postural task dependence shapes vestibular reflexes. We investigated whether vestibulocollic reflexes are...

Stabilization of the head in animals with limited capacity to move their eyes is key to maintain a stable image on the retina. In many birds, including pigeons, a prominent example for the important role of head stabilization is the characteristic head-bobbing behavior observed during walking. Multimodal sensory feedback from the eyes, the vestibular system and proprioceptors in body and neck i...

The Journal of Clinical Pediatric Dentistry Volume 25, Number 2/2000 147 INTRODUCTION The craniomandibular system is designed to function as a unit and its parts cannot be considered independently. The idea of a malfunctioning unit is reflected in the term, craniomandibular disorders, (CMD) which is a collective term embracing a number of clinical problems that involves the masticatory musculat...

Determining the reliability of measurements used to quantify head-neck motor control is necessary before they can be used to study the effects of injury or treatment interventions. Thus, the purpose of this study was to determine the within- and between-day reliability of position tracking, position stabilization and force tracking tasks to quantify head-neck motor control. Ten asymptomatic sub...

[Purpose] The purpose of this study was to investigate the preventive effects of stretching and stabilization exercises on muscle fatigue of the neck erector spine and upper trapezius muscles. [Subjects and Methods] The subjects of this study were 26 healthy university students (14 males and 12 females). Each subject was assigned randomly to each of three study groups in order to prevent order ...

PURPOSE We systematically reviewed randomized and quasi-randomized clinical trials in the literature to assess the efficacy of neck stabilization and postural exercises on pain, neck range of motion, and time off work in adults with acute whiplash-associated disorders. METHODS Electronic databases, reference lists of relevant Cochrane reviews, reference lists of studies selected for inclusion...

Purpose: Physical condition and posture are related to bio-psychological health. Overweight in the children is also associated with musculoskeletal deformities. The current study aimed to compare the effect of conducting an 8-week of selected football activities and corrective exercises on postural deformities, the factors of physical readiness, and body composition in three male groups, includ...

INTRODUCTION Neck pain (NP) is common among military helicopter pilots. Older age and more flight-hours have been associated with pilots with a history of NP. However, modifiable neuromuscular and musculoskeletal characteristics such as neck proprioception, strength, flexibility, and posture have rarely been investigated in military helicopter pilots with a history of NP. The purpose of the stu...
