Impact of virtual reality games on psychological well-being and upper limb performance in adults with physical disabilities: A pilot study.

INTRODUCTION: There is limited information regarding the effects of interactive virtual reality (VR) games on psychological and physical well-being among adults with physical disabilities. We aimed to examine the impact of VR games on psychological well-being, upper limb motor function and reaction time in adults with physical disabilities. METHODS: Fifteen participants completed the intervention using Wii VR games in this pilot study. Depressive, Anxiety and Stress Scales (DASS) and Capabilities of Upper Extremity (CUE) questionnaires were used to measure psychological well-being and upper limb motor function respectively. Upper limb reaction time was measured using reaction time test. RESULTS: Results showed that there was a significant difference (p<0.05) in DASS questionnaire and average reaction time score after intervention. CONCLUSION: There is a potential for using interactive VR games as an exercise tool to improve psychological wellbeing and upper limb reaction time among adults with disabilities.

Nutrition and Frailty: A Review of Clinical Intervention Studies.

Frailty is one of the major health concerns in aging. It is considered a geriatric syndrome characterized by muscle weakness, sarcopenia and fatigue. It is also associated with several adverse health outcomes, including disability. Literature shows that there are a number of studies conducted to define the relationship between frailty and nutrition. The majority is from cross sectional, longitudinal, and cohort studies. Few intervention studies using micronutrients, macronutrients, nutritional supplement, or food regimens have been found. This review examines the nutrition intervention studies targeted towards older adults with frailty, and evaluates the effectiveness of nutrition interventions on frailty indicators. Twenty-four intervention studies from six electronic databases met the inclusion criteria. Sixteen were randomized controlled clinical trials; one was a quasi-experimental design, whilst the rest were controlled trials. Participants included in the studies differed in terms of age and frailty status. The studies were inconsistent in intervention type, duration, and targeted outcomes. Most of the studies indicated that modification of nutrition quality, either by giving supplements or by improving diet intake, could improve strength, walking speed, and nutritional status in majority of frail or pre-frail older adults. However, there was limited evidence on the effectiveness of intervention on inflammatory status and other biomarkers related to frailty due to limited number of studies targeting frailty biomarkers as a major outcome.

Effects of balance-focused interactive games compared to therapeutic balance classes for older women.

OBJECTIVE: The prospective pre-post control study was designed to evaluate the effect of introducing balance-focused interactive virtual-reality games to community-dwelling older women to improve their agility, balance and functional mobility. METHOD: The study was set in a senior citizens' club in Cheras, Kuala Lumpur, Malaysia. The participants were 36 community-dwelling older women. Participants were randomly divided into either a group undertaking balance-focused virtual-reality games or a group doing therapeutic balance exercises. The program lasted 6 weeks and was conducted twice a week for 40 min during each session. As the main outcome measures, the results of the Ten Step Test (TST), postural sway (overall performance index, OPI) and the Timed Up and Go test (TUG) were measured pre- and post-intervention to evaluate agility, balance and functional mobility, respectively. RESULTS: Although both groups improved in OPI (F = 4.63, p < 0.001), TST (F = 46.15, p < 0.001) and TUG (F = 52.57, p = 0.03), combined time and group interaction only improved in the TUG (F = 4.54, p < 0.05). No significant differences between the two groups were found in terms of TST (F = 0.02, p = 0.86), OPI (F = 0.66, p = 0.42), and TUG (F = 0.11, p = 0.74). CONCLUSION: Older people could improve their agility, balance and functional mobility by complementing therapeutic balance exercises with active participation in interactive virtual-reality games at home or in the community.
