Grade IV – Low amplitude, rhythmically oscillating joint glide that is performed at the end of the available arthrokinematic joint play. Designed to physically stretch the joint capsule. Grade V – This grade refers to the use of a single high-velocity, low-amplitude thrust performed at the end of the available joint play.
PPIVM assessments test the movement available at a specific spinal level through the application of a passive physiological movement. [ 1 ] [ 2 ] Cervical PPIVMs can be performed in cervical lateral flexion or rotation, with the therapist restricting movement beyond a certain cervical level by blocking with the hand; this allows the ...
A 2005 study by Abbott et al. suggested that as an assessment technique, PAIVMs are highly specific, but not sensitive, in the detection of lumbar segmental instability. [3] A 1993 study by Watson and Trott suggested that PAIVM examinations are reliable when identifying symptomatic vertebral joints when assessing for cervicogenic headache. [4]
[3] In recent years, practitioners of physical therapy and rehabilitation have suggested that the existence of the arthrokinetic reflex implies that joint mobilization may be useful in addressing chronic pain conditions such as lower-back pain [ 4 ] or as a way to improve sports-related performance.

The atlanto-occipital joint may be dislocated, especially from violent accidents such as traffic collisions. [1] This may be diagnosed using CT scans or magnetic resonance imaging of the head and neck. [1]
Concussion grading systems are sets of criteria used in sports medicine to determine the severity, or grade, of a concussion, the mildest form of traumatic brain injury.At least 16 such systems exist, [1] and there is little agreement among professionals about which is the best to use. [2]
[2] [page needed] Owing to the obliquity of the trochlea of the humerus, this movement does not take place in the antero-posterior plane of the body of the humerus. When the forearm is extended and supinated , the axis of the arm and forearm are not in the same line; the arm forms an obtuse angle with the forearm, known as the carrying angle .
