In order to prevent the symptoms of vascular insufficiency, anti-platelet drugs are given to maintain cerebral blood flow. This makes the platelets less sticky, the blood thinner and helps better flow. But this is illogical. The essential change is of a mechanical nature. If the cervical spine could be realigned and the intervertebral spaces widened, a normal state of blood flow would be restored.
Physiotherapy can, at best, only offer marginal relief.
It is better avoided. In situations where the patient suffers acute giddiness, it is useful to restrict the movement of the neck with a soft collar. Sudden neck movements cause the spur to impinge on the cervical nerves and blood vessels and reduce the blood to the brain. This creates a situation where the patient, sometimes becomes afraid of moving the neck. In the long run, of course, a collar is to be avoided as it stiffens the neck muscles and pushes the neck out of alignment.
