Abstract
Objectives: To evaluate the feasibility and acceptability of an exergame intervention as a tool to promote
physical activity in outpatients with schizophrenia.
Design: Feasibility/Acceptability Study and Quasi-Experimental Trial.
Method: Sixteen outpatients with schizophrenia received treatment as usual and they all completed an
8-week exergame intervention using Microsoft Kinect® (20 min sessions, biweekly). Participants completed pre and post treatment assessments regarding functional mobility (Timed Up and Go Test), functional fitness performance (Senior Fitness Test), motor neurological soft signs (Brief Motor Scale), hand grip strength (digital dynamometer), static balance (force plate), speed of processing (Trail Making Test), schizophrenia-related symptoms (Positive and Negative Syndrome Scale) and functioning (Personal and Social Performance Scale). The EG group completed an acceptability questionnaire after the intervention.
Results: Attrition rate was 18.75% and 69.23% of the participants completed the intervention within the
proposed schedule. Baseline clinical traits were not related to game performance indicators. Over 90% of
the participants rated the intervention as satisfactory and interactive. Most participants (76.9%) agreed
that this intervention promotes healthier lifestyles and is an acceptable alternative to perform physical
activity. Repeated-measures MANOVA analyses found no significant multivariate effects for combined
outcomes.
Conclusion: This study established the feasibility and acceptability of an exergame intervention for
outpatients with schizophrenia. The intervention proved to be an appealing alternative to physical activity.
Future trials should include larger sample sizes, explore patients' adherence to home-based exergames and consider greater intervention dosage (length, session duration, and/or frequency) in order to achieve potential effects.
