BACKGROUND: Vestibular rehabilitation (VR), specifically, VR with dynamic computerized posturography (CDP) has proven to be useful to improve balance and reduce the risk of falling in old patients. Its major handicap is probably its cost, which has hindered its generalisation. One solution to reduce this cost is performing VR with mobile posturography systems, which allow assessment of stability at the center of body mass in daily-life conditions. Also, rehabilitation with vibrotactile neurofeedback training could be used in dynamic tasks. OBJECTIVE: To assess whether two different protocols of vestibular rehabilitation (using CDP and the Vertiguard system) show significant differences in the improvement of balance among older persons with imbalance METHODS: A clinical trial comparing VR with CDP exercises and VR with mobile posturography (Vertiguard) exercises, was designed. The participants were people over 65 years, with imbalance. The composite (average balance) in the sensory organization test (SOT) of the CDP was the main outcome measure; it was compared before and 3 weeks after VR, and between both intervention groups. RESULTS: 40 patients were included in the study (19 in the CDP-VR group and 21 in the Vertiguard-VR group). Average balance was significantly improved in both intervention groups (51% pre-VR versus 60% post-VR, p = 0.002, CDP-VR group; 49% pre-VR versus 57% post-VR, p = 0.008, Vertiguard-VR group); no significant differences in this improvement were found comparing both groups (p = 0.580). DISCUSSION AND CONCLUSIONS: VR using mobile posturography is useful to improve stability in old people with instability, showing similar improvement rates to those of VR using CDP.
