Virtual Reality-Based Balance Training in Hemiplegic Patients

This prospective single-blind randomized controlled trial enrolled 43 hemiplegic patients hospitalized in the neurological rehabilitation unit of the University of Health Sciences Ankara Etlik City Hospital. Participants were randomly assigned to a virtual reality (VR) group (n = 23), which received routine physical therapy combined with VR-based balance training, or a conventional therapy (CT) group (n = 20), which received routine physical therapy alone. Interventions were delivered under physiotherapist supervision over 20 sessions, with the VR group receiving an additional 12 sessions of VR-based balance exercises. Outcomes were assessed at baseline, immediately post-treatment, and at an eight-week follow-up, including measures of balance, mobility, functional independence, walking capacity, quality of life, and static balance using the Tecnobody PK252 isokinetic balance measurement system.

The study included 43 hemiplegic patients who met the inclusion criteria and were hospitalized in the neurological rehabilitation unit of the University of Health Sciences Ankara Etlik City Hospital. Patients were randomized into two groups using a sealed-envelope method: 23 patients were assigned to the VR group, which received conventional therapy combined with virtual reality-based balance games, and 20 patients were assigned to the CT group, which received only conventional therapy. The VR group received routine physical therapy and rehabilitation once daily for a total of 20 sessions, in addition to virtual reality-based balance games applied three times a week for 20 minutes per session, totaling 12 sessions, all under the supervision of a physiotherapist. The CT group received only routine physical therapy and rehabilitation once daily for a total of 20 sessions, also under the supervision of a physiotherapist. All patients were evaluated before treatment, at the end of treatment, and eight weeks after the end of treatment using the Berg Balance Test (BBT), Functional Reach Test (FRT), Timed Up and Go Test (TUG), Five Times Sit-to-Stand Test (5xSST), Functional Independence Measure (FIM), Six-Minute Walk Test (6MWT), Stroke-Specific Quality of Life Scale(SS-QOL), and static balance measurements obtained via the Tecnobody PK252 isokinetic balance measurement system.
