ClinConnect Summary

This clinical trial is studying how early rehabilitation can help patients recover from a specific type of balance problem known as acute unilateral vestibular deficit (AUVD). This condition often occurs after surgery to remove a tumor on the balance nerve, called a vestibular schwannoma. The researchers want to find out if practicing certain eye movements soon after surgery can help patients learn to regain their balance and improve their vision. They will use a test called the Head Impulse Test to measure how well the eyes move in response to head movements, which is important for keeping our vision clear when we move.

To be eligible for this trial, participants must be adults aged 65 to 74 who have a unilateral vestibular schwannoma and are scheduled for surgery. They should have certain eye movement measurements that indicate a vestibular problem. Before joining the study, participants will receive all necessary information about the trial at least 15 days before their surgery and will provide consent the day before. If they decide to participate, they can expect to work with physiotherapists during their hospital stay to help with their recovery. It's important to note that some people will not be eligible, such as those with other eye or balance issues, certain medical conditions, or those who have had specific treatments like radiation before surgery.
