Each year, 17.9% of adults working in a computer-dominated work environment develop an episode of chronic neck and shoulder pain. An effective treatment method for chronic pain is postural correction through therapist. The understanding of the relation between cervicoscapular posture and trapezius muscle activity is not fully understood because the anatomy of the scapula is not accessible for d...

[Purpose] The purpose of this study was to investigate the effect of neck retraction taping on forward head posture and the upper trapezius muscle of computer workers during computer work. [Subjects] Twelve males aged 20-30 years were recruited. [Methods] We measured forward head angle and upper trapezius muscle activity during computer work before and after NRT. [Results] The FHP angle signifi...

BACKGROUND Assessment of three-dimensional kinematics and electromyography (EMG) activities is common in patients with chronic neck pain. However, the effect of hand dominance and neck pain location on the measurement of movement and EMG characteristics is still unclear. Therefore, the purpose of this study was to investigate the effect of neck pain location and arm dominance on the scapular ki...

Objectives: This study aimed to evaluate the effect of conventional physiotherapy plus dry needling (DN) technique in patients with chronic nonspecific neck pain with sternocleidomastoid (SCM) and upper trapezius (UT) muscles involvement.                                                                               Methods: This study was designed as a single-blind randomized clinical trial. A...

UNLABELLED The most common complication of neck dissection is shoulder dysfunction due to manipulation of spinal accessory nerve, resulting in trapezius muscle atrophy mainly in procedures involving the posterior neck triangle. AIM This study used electromyography to evaluate the injury to the spinal accessory nerve following neck dissection. MATERIALS AND METHODS Prospective case series of...

Neck muscle fatigue has been shown to alter an individual's balance in a similar way to that reported in subjects suffering from neck pain or subjects that have suffered a neck injury. The main purpose of the present study was to quantify the effects of neck fatigue on neck muscle electromyography (EMG) activity, balance, perceived fatigue and perceived stability. Forty four elite amateur rugby...

The countermanding (or stop signal) task requires subjects try to withhold a planned movement upon the infrequent presentation of a stop signal. We have previously proposed a within-trial measure of movement cancellation based on neck muscle recruitment during the cancellation of eye-head gaze shifts. Here, we examined such activity after either a bright or dim stop signal, a manipulation known...

[Purpose] The purpose of this study was to compare the cervical extension angle and the upper trapezius muscle activity between overhead work and below-knee work. [Subjects] Twelve males aged 20-30 years, were recruited. [Methods] We measured the cervical extension angle and upper trapezius muscle activity during overhead work and below-knee work. [Results] The results show that the cervical ex...
