Examiner flexes the cervical spine 20-30 degrees. Maintain for 1 min.
The Supine Head-Hanging Positional Test (SHHPT) dDagnoses Benign Paroxysmal Positional Vertigo ... the SHHPT in patients with history of BPPV in which the evaluator has failed to elicit nystagmus in either D-H or Roll Test. Dan wordt het hoofd van de patiënt naar rechts gedraaid en wordt nagekeken of dit een nystagmus uitlokt (zie figuur 1). This test is to assess the horizontal semicircular canal Patient is supine. Repeat to opposite side. Test Position: Supine.
HC-BPPV is diagnosed by the supine roll test (the Pagnini-McClure maneuver), in which the head is turned by about 90° to each side while supine (Fig. Supine Roll test.
Then the examiner quickly rotates the head 90° to the left side, and checks for vertigo and nystagmus.
Geotropic Nystagmus = Canalithiasis Horizontal CRT
Supine roll試験＋Gufoni法（背地性） 水平半規管型BPPVの診断。 Spine roll試験で眼振が強い向き＝坐位前屈30°の時の眼振の向きに対して、逆向いて、眼振のでる天井向きへぐるっと回って、起き上がる。これで向地性の水平半器官型に移行できます。 Purpose: To assess the contribution of the sacroiliac joint to an apparent leg length discrepancy. Performing the Test: The examiner grasps the patient's legs above the ankles and fully flexes them, then extends them.
Both the test and the treatment for HC-BPPV are different than PC. The supine roll test (Figure 2) is performed by rotating the patient's head from neutral to one side while the patient is lying supine. 2.
5B ). If the patient reacts violently during the roll test, immediately turn the patient to the opposite side and perform a Lempert 360° roll. De supine roll test laat toe een horizontaal kanaal BPPV te objectiveren. 5A ) or toward the ceiling (apogeotropic nystagmus)( Fig. De patiënt kijkt recht voor zich uit en wordt van een zittende houding recht naar achter gebracht (supine position), met de kin tegen de borstkast. The Motion Sensitivity Test begins with the long sit to supine with head hanging movement of the SHHP. Turn head 90d to one side.
This tool is not appropriate for differential diagnosis.
Procedure: Begin with the patient sitting length-wise on the examination table; Place the Frenzel/VNG goggles on the patient; Guide the patient into a supine position. -Diagnostic Maneuvers: 1. Determining when to use Bow and Lean Test: If the Roll Test is positive, this test has good clinical utility to assist in determining side of involvement if the Roll Test is inconclusive .
BPPV). During this maneuver, horizontal nystagmus may beat toward the ground (geotropic nystagmus)( Fig. Roll Test (1 (See O’Sullivan 5th ed. Efficacy as determined by remission rates (Lee, 2010; n = 211; mean age = 50.7 (15.5) years) p.1010) Test of Horizontal SCC 5%) Supine, position head in 20d of flexion. Horizontal Roll Test.
Will be positive to both sides, with one side being worse. The roll test can determine whether the horizontal semicircular canal is involved. The problematic semicircular canal can be identified based on the characteristics of the observed nystagmus. If the left side is affected but the test is performed with the head turned to the right, the nystagmus would be up-beating and torsional to the right). These tests allow a physician to observe the nystagmus elicited in response to a change in head position. The examiner then compares the two medial malleoli to see if a difference in position is present. 5).
From the sitting position, have the patient lie back into supine position (this is different than Dix- Hallpike because the patient just goes straight back [no head turn] and the patient stops at supine [not head extended back like Dix-Hallpike]. The roll test requires the person to be in a supine position with their head in 30° of cervical flexion. After waiting for any nystagmus or vertigo to subside the test is performed to the opposite side. Return head to midline. Have the patient sit up, while keeping the legs extended.
