OBJECTIVE To assess the effectiveness of the anchors in the balance rehabilitation of participants with chronic peripheral vestibulopathy who failed to respond positively to conventional rehabilitation for dynamic balance and gait. DESIGN Assessor-blind, randomized controlled trial. SETTING Department of Otoneurology and Laboratory of Assessment and Rehabilitation of Equilibrium. PARTICIPANTS Women with chronic dizziness of peripheral vestibular origin (n=42), who continued to show otoneurological symptoms for more than 6 months after starting classic VR, with no clinical improvement observed. INTERVENTIONS Participants were randomly assigned to receive a clinical intervention with the anchor system, a clinical intervention without the anchor system, or no intervention or anchor system. The intervention was based on multi-sensory exercises for 6 weeks, twice a week, totaling 12 sessions, in groups of up to four participants, with an average time of 40 minutes per session. MAIN OUTCOME MEASURES AND FOLLOW-UP The primary outcome was functional balance as assessed by the short version of the Balance Evaluation Systems Test (Mini-BESTest). The secondary outcomes were gait parameters of step width (m), step length (m), and gait speed (m/sec).The measures were assessed pre- and post- intervention, and after a 3-month follow-up period. RESULTS The proposed intervention was beneficial for dizziness, balance, and gait for both groups studied. At the 3-month follow-up, only the group that used anchors retained the benefits related to the physical aspects of dizziness, balance, and gait. CONCLUSIONS The present study found that the proposed intervention protocol, with or without the use of anchors, was beneficial for improving the dizziness, balance, and gait. However, retention of the benefits achieved through the exercise protocol was observed only for those using the anchor system, which promotes the use of haptic information. The use of anchors was effective, in short protocols (12 weeks), with maintenance of results after 3 months.
