Dizziness is a predictor factor for the risk of falls in institutionalised older adults in Brazil.

Considering the small number of studies aimed at evaluating outcomes related to dizziness and falls in the older adults who live in long-term care facilities, especially in north-eastern Brazil, and considering the negative impact of these events on the quality of life of these individuals, this study purpose was to evaluate dizziness as a predictor of risk of falls in institutionalised older adults. This cross-sectional analysis of data on falls and dizziness of 187 institutionalised older adults carried out between the years 2014 and 2016. The data collection instruments used were a socioeconomic and demographic questionnaire and questionnaires for assessing variables related to falls. The different diagnostic methods were compared using the Spearman correlation, and the Dizziness variable was evaluated by means of logistic regression. Inferential statistical analysis showed a significant association between dizziness and number of morbidities (p = .03) and dizziness and a history of falls (p = .04). Spearman's correlation analysis revealed statistically significant results only for FES-I (Falls Efficacy Scale-International) (p < .01). Dizziness was a predictor of risk of falls and that it was associated with a greater number of morbidities and previous history of falls. Implementing rehabilitation practices to reduce dizziness symptoms can significantly reduce the risk of falls for institutionalised older adults.

Immersive virtual reality is effective in the rehabilitation of older adults with balance disorders: A randomized clinical trial.

QUESTION: What are the effects of immersive virtual reality (IVR) training compared to conventional physiotherapy on body balance and risk of falls in older adults with balance disorders? DESIGN: A randomized controlled trial with two intervention arms, concealed allocation, per-protocol analysis, and blinded assessment. PARTICIPANTS: Thirty-seven older adults with balance disorders and risk of falling. INTERVENTION: Participants were randomized into two groups: a control group, which received balance training with conventional physiotherapy using multimodal circuit exercises, and an experimental group, which received balance training using immersive virtual reality. Both groups received 16 individual sessions, twice a week. OUTCOME MEASURES: The primary outcome was functional balance. Secondary outcomes were static balance, gait speed, functional range, dizziness symptoms, and fear of falling. Safety was ensured by assessing any adverse events during the intervention. RESULTS: After 16 sessions, in the intragroup analysis, the functional balance score in the experimental group increased by 3.00 (95% CI 1.42 to 4.57) and in the control group by 3.88 (95% CI 2.16 to 5.59). Both groups improved in assessments of sensory interaction and anterior reach. Only the experimental group presented increased mobility and reduced dizziness. After two months, there was a maintenance of gains in functional balance and a reduction of the gains in functional reach for both groups. In the intergroup comparison, there was no significant difference. CONCLUSION: Immersive Virtual Reality training proved to be effective for balance-related outcomes, although it was not superior to conventional therapy. TRIAL REGISTRATION: RBR-3tk7fw.

Effects of Resistance and Combined training on Vascular Function in Type 2 Diabetes: A Systematic Review of Randomized Controlled Trials.

BACKGROUND: Cardiovascular disease (CVD) is the main cause of mortality in type 2 diabetes (T2D). Exercise can reduce the risk factors associated with CVD in T2D patients. However, research evaluating its beneficial effects in these patients has used different measurement protocols and types of exercise, complicating comparison. AIM: To assess the effects of resistance training (RT) and combined training (CT) on the vascular function of T2D patients. METHODS: A database search (MEDLINE, Scopus, and Web of Science) was performed to identify relevant articles that were published up to August 2017. Only original studies evaluating the effects of RT or CT interventions on vascular function in T2D patients were included. The articles were reviewed independently by at least three reviewers. The Cochrane guidelines were used to assess the methodological quality of the studies. Fourteen studies were finally included. Two studies only used RT and twelve studies used CT as intervention strategy. RESULTS AND CONCLUSIONS: The results show that resistance training is a useful means for primary treatment of vascular diseases and maintenance of vascular function in T2D patients. However, more studies are necessary to gain full knowledge of the beneficial effects and to identify tailored exercise plans to optimize these benefits. The information provided in this review may help to improve current treatment of vascular diseases in T2D patients and to design future studies.
