[Purpose] This study investigated upper-extremity muscle activities in natural, ideal, and corrected head positions. [Subjects and Methods] Forty subjects with a forward head posture and rounded shoulder were recruited and randomly assigned to the natural head position group (n = 13), ideal head position group (n = 14), or corrected head position group (n = 13). Muscle activities were measured ...

background motor skills disorder in children with motor dys-function is a common disorder in childhood. the aim of this study was to investigate the prevalence and severity of musculoskeletal disorders in children with developmental coordination disorder in comparison with healthy children. material and methods using developmental disorder coordina-tion questionnaire (dcdq'07), 59 male children...

Conservative treatment of thoracic outlet syndrome consists initially of pain control and medicinal and physical measures. Therapy then addresses tight muscles, with strengthening of weakened neck and shoulder girdle muscles. Range of motion and nerve gliding exercises are instituted simultaneously, and the patient is educated in proper posture and ergonomics at home and in the work setting.

PURPOSE Recent epidemiological research has revealed that gender differences exist in concussion incidence but no study has investigated why females may be at greater risk of concussion. Our purpose was to determine whether gender differences existed in head-neck segment kinematic and neuromuscular control variables responses to an external force application with and without neck muscle preacti...

Neck pain in association with the dynamic work environment of the fighter pilot is a well-discussed issue. Spinal symptoms in these pilots were recognized as a serious aero medical problem. Often described contributing factors of neck pain in this population are head movements under high +Gz load, seat-back angle, forward bent posture, head worn equipment, the use of night vision goggles and nu...

OBJECTIVE To assess whether "phasic" exercises, including rapid eye-head-neck-arm movements, can benefit patients with chronic cervical injuries. DESIGN A randomized, controlled, double blind study involving 30 chronic patients, who were allocated to either group 1 or group 2. The study period was for 8 wk. SETTING The study was conducted in a private practice. PATIENTS Thirty chronic mot...

In flesh flies Neobellieria bullata, we investigated a resistance reflex that maintains upright head posture around the roll axis relative to the thorax. The gain of the reflex depends upon the fly's behavioral state: moving flies immediately correct 90 % of the amplitude of experimentally imposed roll perturbations, returning the head almost to the fully upright position; motionless flies allo...
