Abstract
Introduction. Virtual Rehabilitation (VRh) systems are also used to treat elderly patients. It's essential to study the suitability of these systems in areas such as usability, enjoyment, comfort, or feeling of success and control.
Methods. To carry out the suitability evaluation, we used ABAR, a VRh system, based on the Wii Balance Board, intended for balance recovery of patients with different pathologies. We choose SEQ (Suitability Evaluation Questionnaire), which includes 14 questions, 13 of them with a response graded on a 5-point Likert Scale (710, 12 and 13 inversed point), and a last open question. Patients completed SEQ after the first session with ABAR. Inclusion criteria were: age more than 65, balance disorders. Exclusion criteria were: dementia, severe visual deficit, severe hearing impairment, hemispatial neglect, clinical instability, unsolved acute trauma injury and birth injury.
Results. The sample consisted on 15 elderly patients, 8 men and 7 women. Two patients were illiterate, 10 patients had primary studies. The average age was 81, mean Barthel index: 72. SEQ shows very good results: patients enjoyed the system (Q1, mean 4.60), they didnt felt confused or disoriented (Q8, mean 4,9) and patients thought that ABAR will be helpful for their rehabilitation (Q11, mean 4.20). Global score media was 54,4 (13-poor suitability to 65-excellent suitability). Cronbach's alpha was 0,7.
Conclusions. Elderly patients enjoyed ABAR, a VRh system and they did not felt discomfort. Inclusion of VRh systems in the rehabilitation process of elderly people will improve the motivation and increase their adherence to the treatment.
