Patients with multiple sclerosis (PwMS) have a high level of fatigue and a reduced quality of life (QoL) due to the impact of multiple sclerosis (MS). Virtual reality-based therapy (VRBT) is being used to reduce disability in PwMS. The aim of this study was to assess the effect of VRBT on fatigue, the impact of MS, and QoL in PwMS. Methods: A systematic review with meta-analysis was conducted through a bibliographic search on PubMed, Scopus, Web of Science, and PEDro up to April 2021. We included randomized controlled trials (RCTs) with PwMS that received VRBT in comparison to conventional therapy (CT) including physiotherapy, balance and strength exercises, and stretching or physical activity, among others; or in comparison to simple observation; in order to assess fatigue, MS-impact, and QoL. The effect size was calculated using Cohen’s standardized mean difference with a 95% confidence interval (95% CI). Results: Twelve RCTs that provided data from 606 PwMS (42.83 ± 6.86 years old and 70% women) were included. The methodological quality mean, according to the PEDro Scale, was 5.83 ± 0.83 points. Our global findings showed that VRBT is effective at reducing fatigue (SMD −0.33; 95% CI −0.61, −0.06), lowering the impact of MS (SMD −0.3; 95% CI −0.55, −0.04), and increasing overall QoL (0.5; 95% CI 0.23, 0.76). Subgroup analysis showed the following: (1) VRBT is better than CT at reducing fatigue (SMD −0.4; 95% CI −0.7, −0.11), as well as in improving the mental dimension of QoL (SMD 0.51; 95% CI 0.02, 1); (2) VRBT is better than simple observation at reducing the impact of MS (SMD −0.61; 95% CI −0.97, −0.23) and increasing overall QoL (SMD 0.79; 95% CI 0.3, 1.28); and (3) when combined with CT, VRBT is more effective than CT in improving the global (SMD 0.6, 95% CI 0.13, 1.07), physical (SMD 0.87; 95% CI 0.3, 1.43), and mental dimensions (SMD 0.6; 95% CI 0.08, 1.11) of QoL. Conclusion: VRBT is effective at reducing fatigue and MS impact and improving QoL in PwMS.

(1) Background: Mild cognitive impairment in older adults is a condition characterized by a decrease in mental abilities that affects their quality of life. The aim of this study is to evaluate the effects of an aerobic training program based on dance on depression, sleep quality, and quality of life in older adults with mild cognitive impairment. (2) Methods: This study employed a randomized controlled trial design with a total of 92 older adults with cognitive impairment, randomly assigned to an experimental group (n = 47) undergoing dance-based aerobic training and a control group (n = 45) who did not receive any intervention. Depression was assessed using the Yesavage Geriatric Depression Scale, sleep quality through the Pittsburgh Sleep Quality Index (PSQI), and quality of life through the SF-36 questionnaire. (3) Results: Statistically significant improvements were observed in depression (t(46) = 4.783, p = 0.000) and in the PSQI domains: subjective sleep quality (t(46) = 3.333, p = 0.002, and Cohen’s d = 0.35), sleep duration (t(46) = 5.511, p = 0.000, and Cohen’s d = 0.73) and PSQI total score (t(46) = 2.116, p = 0.040, and Cohen’s d = 0.20). Regarding quality of life, improvements were observed in all domains of the questionnaire: the general health (t(46) = −9.374, p = 0.000, and Cohen’s d = 0.03), physical function (t(46) = −9.374, p = 0.000, and Cohen’s d = 0.03), the physical role (t(46) = −5.954, p = 0.000, and Cohen’s d = 1.06), the emotional role (t(46) = −6.200, p = 0.000, and Cohen’s d = 0.80), social function (t(46) = −5.585, p = 0.000, and Cohen’s d = 0.53), physical pain, (t(46) = −9.224, p = 0.000, and Cohen’s d = 1.04), vitality (t(46) = 2.289, p = 0.027, and Cohen’s d = 1.27), mental health, (t(46) = −7.985, p = 0.000, and Cohen’s d = 1.33), the physical summary component, (t(46) = −13.532, p = 0.000, and Cohen’s d = 1.81), and in the mental summary component (t(46) = −10.6 81, p = 0.000, and Cohen’s d = 0.06); (4) Conclusions: The results of the present study showed that they suggest that a dance-based aerobic training program improves mental health and quality of life in older people with mild cognitive impairment, providing a non-pharmacological approach to improve general well-being in this population.

Background/Objectives: The purpose of this study has been to evaluate the effects of a dance-based aerobic training program on frailty, cognitive impairment, executive functions, and verbal fluency in older adults with mild cognitive impairment. Methods: Randomized clinical trial, whose sample was made up of 92 older adults, of which 47 performed rhythmic physical activity for 12 weeks. Data on frailty were collected through FRAIL, cognitive function through the Mini-Mental State Examination (MMSE), cognitive impairment through The Montreal Cognitive Assessment (MoCA), verbal fluency using the Isaac test, and executive functions with the Trail Making Test (TMT). All variables were measured before and after the intervention by an independent researcher blinded to the treatment. Results: Participants in the experimental group showed statistically significant improvements in frailty (Cohen’s d = 0.60), cognitive function (Cohen’s d = 0.98), cognitive impairment (Cohen’s d = 1.22), verbal fluency (Cohen’s d = 0.61) and executive functions (Cohen’s d = 0.64). Conclusions: This study demonstrated that a 12-week dance-based aerobic training program can significantly reduce frailty and improve cognitive abilities in older adults with mild cognitive impairment. These improvements suggest that the intervention is not only effective in terms of physical health, but also in promoting mental health and general well-being.

(1) Background: Nowadays, it is essential to implement new non-pharmacological strategies, such as rhythmic physical activity, to improve mental health and quality of life in both individuals experiencing normal brain aging and those with cognitive impairment. Therefore, the objective of this study is to identify the effects of rhythmic physical activity interventions on mental health and quality of life in older adults, with or without mild cognitive impairment; (2) Methods: We conducted a systematic review with a meta-analysis, searching the Pubmed, Scopus, Web of Science, and Cochrane Plus databases using specific keywords. We selected studies that included rhythmic physical activity as the primary intervention for patients aged 65 and above, with or without cognitive impairment. We assessed the methodological quality of the articles using the PEDro scale; (3) Results: Out of 961 identified studies, we included 11 in this review, all of which employed rhythmic physical activity as an intervention. The selected studies consistently measured depression, anxiety, and quality of life; (4) Conclusions: This review demonstrates that rhythmic physical activity can effectively improve depression, anxiety, and quality of life in older adults, whether or not they have mild cognitive impairment. However, it is worth noting that while we have identified beneficial outcomes, the evidence supporting the use of rhythmic physical activity in enhancing depression, anxiety, and quality of life in older adults with or without mild cognitive impairment remains somewhat limited.

(1) Background: Numerous exercise programs that improve physical capacity and the risk of falls in older adults have been proposed with varying degrees of success. A novel approach may be to use a video game system that uses real-time force feedback to train older adults. The aim of this study was to evaluate the effects of a Nintendo™ Wii-based exercise program on physical function and risk of falls in older people. (2) Methods: This 12-week randomized controlled clinical trial involved 73 participants: 36 individuals participating in a control group (CG) and 37 in an experimental group (EG) participating in a combined program. Balance was measured using the Tinetti scale, flexibility was assessed with the back scratch test and the sit-and-reach test, and lower body strength was assessed with the 30 s chair stand-up test. (3) Results: The results of this study show significant improvements in balance, gait, flexibility, and strength of the lower limbs compared to a control group. (4) Conclusions: A Nintendo™ Wii-based exercise program for seniors produces improvements in the physical health of older adults. These improvements highlight the importance of integrating physical exercise through video games as an effective strategy to improve the general health and quality of life of older adults.

Background: Older adults with mild cognitive impairment are at increased risk for physical decline and falls due to decreased strength, flexibility, balance, and gait. Dance-based aerobic training has emerged as a promising and enjoyable intervention to promote physical function and cognitive stimulation. This study aimed to evaluate the efficacy of a 12-week structured dance-based aerobic program, based on line dancing and Latin rhythms (e.g., salsa, merengue, and bachata), in improving functional capacity and reducing the risk of falls in older adults with mild cognitive impairment. Methods: A randomized controlled trial was conducted with 92 participants aged ≥65 years diagnosed with mild cognitive impairment. The participants were randomly assigned to an experimental group (dance-based training, twice weekly for 12 weeks) or a control group (usual activity). Outcomes included muscle strength (grip dynamometry), flexibility (back scratch and chair sit-and-reach tests), gait speed (Timed Up and Go test), balance (Tinetti scale), and total falls risk score (Tinetti). Mixed ANOVA and Cohen’s d were used for statistical analysis. Results: Significant improvements were observed in the experimental group on all variables compared to the control group. Muscle strength (p < 0.001, d = 0.86), gait speed (p = 0.026, d = 0.48), and upper and lower extremity flexibility (d = 0.43–0.79) improved significantly. The balance and gait components of the Tinetti scale also increased (p = 0.007 and p = 0.048, respectively), as did the total Tinetti score (p = 0.002, d = 0.67), indicating a reduction in the risk of falls. Conclusions: These findings suggest that, under structured conditions, dance-based aerobic training may serve as a promising non-pharmacological strategy to support healthy aging in older adults with mild cognitive impairment, although further validation in larger cohorts is needed.
