Title: Does the Addition of Virtual Reality Training to a Standard Program of Inpatient Rehabilitation Improve Sitting Balance Ability and Function After Stroke? A Blinded Randomized Controlled Trial.
Brief Summary: The purpose of this study is to determine if the addition of 10 to 12 sessions of sitting balance exercises using virtual reality training will provide additional gains in balance ability and function over standard inpatient rehabilitation in stroke patients.
