Feasibility, safety, acceptability, and functional outcomes of playing Nintendo Wii Fit PlusTM for frail older adults: A randomized feasibility clinical trial.

BACKGROUND: Recently, interactive video games (IVGs) have been used as a health-care intervention that provides both exercise and cognitive stimulation. Several studies have shown that IVGs can improve postural control, gait, cognition, and functional independence in elderly people and patients with neurological disease. However, there is a lack of evidence about the effects of IVGs on frail and pre-frail elderly people. The aim of this study was to evaluate the feasibility, safety, and acceptability of playing Nintendo Wii Fit Plus™ (NWFP) interactive video games, and the functional outcomes (postural control, gait, cognition, mood, and fear of falling) in frail and pre-frail older adults. METHODS: This study is a randomized controlled, parallel-group, feasibility trial. Participants were frail and pre-frail older adults randomly assigned to the experimental group (EG, n = 15) or control group (CG, n = 15). Participants in the EG performed 14 training sessions, lasting 50 min each, twice a week. In each training session, participants played five of 10 selected games, with two attempts at each game. Participants in the CG received general advice regarding the importance of physical activity. All participants were assessed on three occasions by a blinded physical therapist: before and after intervention, and 30 days after the end of the intervention (follow-up). We assessed the feasibility (score of participants in the games), acceptability (game satisfaction questionnaire), safety (adverse events during training sessions), and functional outcomes: (1) postural control (Mini-BESTest); (2) gait (Functional Gait Assessment); (3) cognition (Montreal Cognitive Assessment); (4) mood (GDS-15); and (5) fear of falling (FES-I). RESULTS: Participants in the EG improved their scores in all 10 games, reported that they understood and enjoyed the tasks of the games, and presented few adverse events during the practice. There was a significant improvement in the Mini-BESTest and Functional Gait Assessment in the EG when compared with the CG (p < 0.05). CONCLUSION: The use of NWFP was feasible, acceptable, and safe for frail older adults and improved their postural control and gait. There were no effects on cognition, mood, or fear of falling. This trial was registered in the Brazilian Registry of Clinical Trials (RBR-823rst) on 11 June 2016.

Effects of Kinect Adventures Games Versus Conventional Physical Therapy on Postural Control in Elderly People: A Randomized Controlled Trial.

OBJECTIVE: To compare the effectiveness of Kinect Adventures games versus conventional physiotherapy to improve postural control (PC), gait, cardiorespiratory fitness, and cognition of the elderly. In addition, we evaluated the safety, acceptability, and adherence to the interventions. MATERIALS AND METHODS: The study was a randomized clinical trial in which 46 elderly individuals were selected, mean age 69.3 (5.34) years. Participants were allocated to the Kinect Adventures Training Group (KATG) or the Conventional Physical Therapy Group (CPTG), 23 individuals in each group. Participants of both groups participated in 14 training sessions lasting 1 hour each, twice a week. The KATG practiced four Kinect Adventures games. The CPTG participated in conventional physiotherapy. The primary outcome was PC: Mini-Balance Evaluation Systems Test (Mini-BESTest), and secondary outcomes were gait: Functional Gait Assessment (FGA), cardiorespiratory fitness: Six-minute step test (6MST), and cognition: Montreal Cognitive Assessment (MoCA). Acceptability was assessed through a questionnaire created by the researchers themselves. Adherence was assessed by the "frequency of the number of elderly individuals who completed the interventions and safety through the presence of adverse effects." Participants were assessed immediately pre- and posttreatment and fourth week after the end of the treatment. Statistical analysis was done through repeated-measures analysis of variance and Tukey post hoc test. RESULTS: Both groups presented a significant improvement in the PC (Mini-BEST), gait (FGA), and cognition (MoCA) posttreatment that was maintained at fourth week after treatment (post hoc Tukey test; P < 0.05). Regarding cardiorespiratory fitness (6MST), the KATG presented improvement posttreatment and maintenance of the results in the fourth week after treatment. CPTG showed improvement only in fourth week after treatment (post hoc Tukey tests; P < 0.05). Regarding the acceptability, the questionnaire showed that both groups were satisfied with regard to the proposed interventions. There was 91% adherence in both training sessions. Regarding the safety, 34% and 26% of the individuals of the KATG and CPTG, respectively, presented adverse effects of delayed muscle pain in the lower limbs after the first session only. CONCLUSION: There were no significant differences between the KATG and CPTG; both interventions provided positive effects on PC, gait, cardiorespiratory fitness, and cognition of the elderly.

Feasibility, safety, acceptability, and functional outcomes of playing Nintendo Wii Fit Plus™ for frail elderly: study protocol for a feasibility trial.

BACKGROUND: Frailty can be defined as a medical syndrome with multiple causes and contributors, characterized by diminished strength and endurance and reduced physiological function that increases the vulnerability to develop functional dependency and/or death. Studies have shown that the most commonly studied exercise protocol for frail older adults is the multimodal training. Interactive video games (IVGs) involve tasks in virtual environments that combine physical and cognitive demands in an attractive and challenging way. The aim of this study will be to evaluate the feasibility, safety, acceptability, and functional outcomes of playing Nintendo Wii Fit PlusTM (NWFP) for frail older adults. METHODS/DESIGN: The study is a randomized controlled, parallel group, feasibility trial. Participants will be randomly assigned to the experimental group (EG) and control group (CG). The EG will participate in 14 training sessions, each lasting 50 min, twice a week. In each training session, the participants will play five games, with three attempts at each game. The first attempt will be performed with the assistance of a physical therapist to correct the movements and posture of the patients and subsequent attempts will be performed independently. Scores achieved in the games will be recorded. The participants will be evaluated by a blinded physical therapist at three moments: before and after intervention and 30 days after the end of the intervention (follow-up). We will assess the feasibility, acceptability, safety, and clinical outcomes (postural control, gait, cognition, quality of life, mood, and fear of falling). DISCUSSION: Due to the deficiencies in multiple systems, studies have shown that multimodal interventions including motor-cognitive stimulation can improve the mobility of frail elderly adults. IVGs, among them the NWFP, are considered as a multimodal motor-cognitive intervention that can potentially improve motor and cognitive functions in the frail elderly. However, there is still no evidence in the literature that proves the feasibility, safety, acceptability, and functional outcomes of this intervention in frail elderly individuals.
