Assessment of total head excursion and resting head posture

Archives of Physical Medicine and Rehabilitation, 1991
Clinicians typically evaluate head posture and cervical range of motion in both standing and sitting positions. There are currently few quantitative data available regarding resting head posture (RHP) or total head excursion (THE), a retraction-protraction gliding range of head motion in the sagittal plane, and where the RHP lies within THE.

The effect of complete dentures on head posture

The Journal of Prosthetic Dentistry, 1989
This study investigated possible changes in head posture after insertion of complete dentures in patients who had been edentulous for at least 6 months. The craniovertical angle was measured with a plastic ruler and protractor assembly, which was aligned with dots made on the skin over the zygomatic arch.

Head Posture and Deprivation of Visual Stimuli

American Orthoptic Journal, 2002
Natural head position (NHP) has been defined as the cranial position that is attained when individuals stand with their visual axes in the true horizontal plane. The visual axis is considered to be a key component in establishing, and maintaining NHP so that, in the absence of visual stimuli, gravitation and muscular proprioception chiefly control head

Approach to abnormal head posture

Strabismus
An abnormal head position (AHP) refers to a condition where the head is deviated from the usual, upright posture considered normal. AHPs can manifest as the chin being raised or lowered, the head tilted to the right or left, the face turned to either side, or a combination of these movements.

Head posture in obstructive sleep apnoea

The European Journal of Orthodontics, 1993
In growing subjects, obstruction of the upper airway may lead to excessive vertical facial development. According to the soft-tissue stretching hypothesis (Solow and Kreiborg, 1977) this could be due to an increased cranio-cervical angulation triggered by the airway obstruction.

Assessing abnormal head posture

Current Opinion in Ophthalmology, 2013
We aim to give a systematic approach on how to assess the cause of a patient's abnormal head posture (AHP).Over the decades, many important clinical observers and teachers have described diagnostic techniques for patients with AHP. Recently, Wong has added a new set of office-based diagnostic criteria that expand and solidify the office assessment of ...

The Nature of Head Postures in Congenital Nystagmus

Archives of Ophthalmology, 1991
We investigated the factors that determine the nature and extent of abnormal head postures in patients with congenital nystagmus. The head positions and eye movements of 16 patients were monitored while they adopted a variety of gaze positions. Five patients displayed a single head posture and four displayed multiple head postures. Six of the nine head

Head postures during naturalistic driving

Traffic Injury Prevention, 2018
A rotated head posture at the time of a rear-end impact is associated with a higher risk of acute and chronic whiplash injury. The objective of this study was to quantify the amplitude and duration of rotated head postures observed in drivers during naturalistic driving.Twenty volunteers (14 males: 36 ± 12 years, 6 females: 27 ± 5 years) drove a 2010 ...

The effect of orthognathic surgery on head posture

The European Journal of Orthodontics, 1991
Changes in resting head and neck posture were studied in 201 patients following five different orthognathic surgery procedures: (1) LeFort I osteotomy for superior repositioning (intrusion) of the maxilla (n = 45); (2) bilateral sagittal split ramus osteotomy for mandibular advancement (n = 78); (3) mandibular setback (n = 19); (4) combined maxillary ...
