A subject must have adequate cervical spine range of motion to allow neck extension, as well as trunk and hip range of motion to lie supine. From the previous point, the use of this maneuver can be limited by musculoskeletal and obesity issues in a subject. [4]
The first two cervical vertebrae, the axis and atlas, are shaped differently from the remaining five. The atlas and axis are responsible for movement of the skull from side to side (cervical rotation to the right and left); also moving forward and backward (cervical flexion and extension). Excessive extension and flexion can disrupt the vertebrae.
Commonly, the VA test involves cervical spine motion to an end-range position of rotation, extension or a combination of both. At this point, the physician assesses for vertebrobasilar insufficiency (VBI) symptoms. If the patient has VBI symptoms during the test, it is considered a positive result and a contraindication for cervical ...
A functional spinal unit (FSU), or motion segment, is the smallest physiological motion unit of the spine to exhibit biomechanical [1] characteristics similar to those of the entire spine. [ 2 ] A FSU consists of two adjacent vertebrae , the intervertebral disc and all adjoining ligaments between them and excludes other connecting tissues such ...
Flexion, extension, and rotation are all concentrated in the area of an abnormal odontoid process or poorly developed ring of C1 which cannot withstand the effects of aging. Type III—A single open interspace between two fused segments. Cervical spine motion is concentrated at single open articulation.
The range of motion describes the total range of motion that a joint is able to do. [5] For example, if a part of the body such as a joint is overstretched or "bent backwards" because of exaggerated extension motion, then it can be described as hyperextended.
The Scoliosis Research Society has proposed a range of 40° and 60° as measured between the upper endplate of Th12 and the upper endplate of S1. [18] Individual studies, although using other reference points, have found normal ranges up to approximately 85°. [18] It is generally more pronounced in females. [18]
The routine use of a cervical collar is not recommended. [2] [3] [6] Cervical collars are also used therapeutically to help realign the spinal cord and relieve pain, [7] although they are usually not worn for long periods of time. [8] Another use of the cervical collar is for strains, sprains, or whiplash.
