Summary
Presbivestibulopathy is defined as a chronic vestibular syndrome characterized by bilateral vestibulopathy verified with vestibular tests. These tests objectively assess vestibular function: video Head Impulse Test (v-HIT) and Vestibular Caloric Tests. Also, there are some questionnaires that serve us for monitoring and prognosis (Dizziness Handicap Inventory). There is currently no specific treatment for presbyvestibulopathy. The objective of this study is to evaluate the effect of L-arginine vs. placebo on symptoms, changes in the results of vHIT tests of patients diagnosed with presbyvestibulopathy. It will be conducted a randomized, double blind, placebo controled clinical trial. Patients will be men and women who meet the diagnostic criteria for Presbyvestibulopathy of the Barany Society. The sample size will be 12 patients per group. The patients in the experimental group will receive L-arginine at a dose of 3 grams divided into three doses of 1 g (capsules) every 8 hours, for 3 months. Patients in the control group will receive placebo at the same dosage. All patients will receive vestibular rehabilitation exercises. At the beginning and the end of the intervention , the following tests will be carried out: vertigo disability questionnaire, vHIT tests, and the Up and Go time test.
