Randomized Controlled Trial Clinical TrialPostural control as assessed with virtual reality.
We studied the use of virtual reality technology as a stimulus in balance examinations. A pilot study was made using a small group of healthy subjects to investigate the effect of alcohol and virtual reality stimulus on the subjects' balance. The tests showed that blood alcohol concentration accounted for almost 50% of the increased lateral body sway velocity. The new stimulus technique based on virtual reality technology seems to be effective and flexible for postural investigations.

Hearing changes and questionnaire responses in patients with paramedian suboccipital vestibular neurectomy.
In order to determine the effectiveness of paramedian suboccipital transmeatal vestibular neurectomy, pre- and postoperative neurotological studies were conducted and questionnaire responses of 30 patients who underwent surgery were evaluated. Hearing was maintained within 10 dB of the preoperative level or improved in 54% of patients 2 years after surgery. Questionnaire responses indicated that all patients suffering from intractable vertigo experienced no vertiginous symptoms after surgery. Based on this study, we conclude that paramedian suboccipital transmeatal vestibular neurectomy is a useful method for relieving ear-related vertigo.
