Although it was considered as a special type of motor neurone disorder, recent studies and case reports indicate that it may be associated with dynamic changes such as ischaemia, myelopathy or atrophy of the spinal cord induced by neck flexion
MRI studies in neck flexion
, which are easy to obtain will show the forward displacement of the posterior wall and a well-enhanced crescent-shaped mass in the posterior epidural space of the lower cervical canal.
Material and Methods: Using nonprobability convenience sampling, we included students (all females) of WMC suffering from neck pain due to neck flexion
Almost 40% of the tracheal length, or approximately 4 cm, can be resected without the need for postoperative neck flexion
or head fixation.
In addition to a suture placed between the skin of the chin point and anterior part of the upper chest in the midline position, we have designed a fiberglass-made brace that weighs 800 g (figure 1) with the intent to maintain constant complete neck flexion
, post-operatively, in patients who refer to our center for tracheal reconstruction.
Tobacco smoke, alcohol, stress, perfumes, oversleeping, fatigue, environmental exposure and neck flexion
Compared to typical desktop computing scenarios, the use of media tablet computers is associated with high head and neck flexion
postures, and there may be more of a concern for the development of neck and shoulder discomfort," said lead investigator Jack T.
It is evident from the literature that there is a 40% decrease in utricular sensitivity with 30[degrees] of neck extension and 15% increase in utricular sensitivity with static neck flexion
(Brandt et al 1981).

This included submaximal AO neck flexion
(10 seconds holding for 10 repetitions), active ROM rotation bilaterally, self median nerve neural glide mobilizations, and cervical stabilization with a small ball behind her head while the arms moved through port-de-bras (Fig.
Shearing forces of neck flexion
are important before the chin hits the chest.
Marker points were digitised using the PEAK motion analysis system (a) and head flexion, neck flexion
, craniocervical, craniothoracic, trunk, lumbar, and anterior pelvic tilt angles were calculated, as shown in Figure 2.
Occipital Neuralgia A pain in the upper neck or back of the head region that is usually caused by neck flexion
or head rotation.
Compared to flat ones, desktops with a 15-degree slope and chairs with a 15-degree forward slope allow less neck flexion
and a larger angle between trunk and thigh while working at the desk.
Sanders and Michalak-Turcotte have noted that dental hygienists frequently work with neck flexion
over 30 degrees, with side bending or rotating, and shoulder abduction over 45 degrees.
