Balance is the result of several body systems working together: the visual system (eyes), vestibular system (ears) and proprioception (the body's sense of where it is in space). Degeneration or loss of function in any of these systems can lead to balance deficits.
[2] [4] [5] Physiologic vertigo may occur following being exposed to motion for a prolonged period such as when on a ship or simply following spinning with the eyes closed. [6] [7] Other causes may include toxin exposures such as to carbon monoxide, alcohol, or aspirin. [8] Vertigo typically indicates a problem in a part of the vestibular ...
Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [ 1 ]
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

Watch the movement of the body in relation to a perpendicular object behind the subject (corner of the room, door, or window). The essential features of the test are as follows: the subject stands with feet together, eyes open and hands by the sides; the subject closes the eyes while the examiner observes for a full minute.
Vertigo or dizziness; Weakness of limbs; Symptoms are frequently worsened by a Valsalva maneuver, or by being upright for long periods of time. The reason that being upright is problematic is that gravity allows increased interaction between the brain stem and the top of the spinal column, increasing symptoms.
This can be simply corrected by sleeping with the arm down next to the body and maintained under a long nightgown. [5] Nightly rotator cuff impingement may lead to an asymptomatic shoulder impingement [6] which explains why over 100 years of research has failed to identify a lesion in the cervical spine that causes this common shoulder/neck pain.
There are several disadvantages proposed by Cohen for the classic maneuver. Patients may be too tense, for fear of producing vertigo symptoms, which can prevent the necessary brisk passive movements for the test. 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 ...
