To systematically review the effectiveness of dance-based programs to improve motor-cognitive dual-task performance in middle-aged and older adults.Five scientific databases were selected to identify the articles included in this systematic review. Ninety-one articles were found in the electronic databases. Fourteen articles fulfilled all inclusion and exclusion criteria. The methodological quality of the studies was assessed with a modified version of Downs and Black checklist. PRISMA guidelines were followed in the data extraction process. The overall effect size of the improvements was calculated through a meta-analysis.All the studies had an acceptable methodological quality. Dance-based interventions had a duration of 8-52 weeks, 1-3 sessions per week, with sessions lasting 40-90 min. According to the overall effect size, dance-based interventions significantly improved dual-task performance (-0.48 with a 95% confidence interval from -0.88 to -0.08).Dance-based intervention programs may be effective at improving the performance on motor-cognitive dual-task in middle-aged and older adults. Apart from the effects on the cognitive Time Up and Go test, dance interventions may also improve speed walking with a cognitive task. All these conclusions must be taken with caution due to the heterogeneity and the small number of articles. Future research can be developed to increase the knowledge on these issues.Implications for rehabilitationInterventions based on dance as part of rehabilitation can improve the performance on TUG under dual-task condition in aging.Interventions based on dance can be effective to improve the development of some tasks of daily life by reducing time in a motor task under dual task condition in aging.Physical therapists, personal trainers and other clinicians can use different types of dance for improving dual-tasking among the adults.

Patients with fibromyalgia (FM) show widespread pain associated with other symptoms such as cognitive problems, depression, and anxiety among others associated with alterations in the central nervous system. The hippocampal subfields had differences in function, histology, and connectivity with other brain regions, and are altered in different diseases. This study evaluates the volumetric differences between patients with FM compared with a healthy control group. A total of 49 women with, and 43 healthy women completed this study. T1-weighted MRI was used to assess brain volume, and FreeSurfer software was used to segment the hippocampal subfields. Women with FM had a significant reduction in most of the hippocampal subfields. The regression equation models were obtained to predict the volume of specific subfields of the right and left hippocampus. These findings provide that women with FM have lower hippocampal subfields volumes compared with healthy women. Besides, regression models show that different covariates, such as age, cognitive impairment, or depression, are related to specific subfields.

Background: Exergame-induced changes in the volume of brain gray matter have not been studied in fibromyalgia (FM). This study evaluates the effects of a 24-week exergame-based intervention on the gray matter volume of different brain structures in patients with FM through magnetic resonance imaging (MRI). Methods: A total of 25 FM patients completed 24 weeks of intervention program, and another 25 FM patients did not receive any intervention. T1-weighted MRI was used to assess brain volume, and FreeSurfer software was used to segment the brain regions. Results: No significant effects on gray matter volume of different structures and total gray matter were found. Conclusions: FM patients did not show significant changes in gray matter brain volume between the control and experimental groups after 24 weeks. FM patients showed significant relationships between peak oxygen consumption (pVO2) and the left and right regions of the hippocampus and the left and right regions of the amygdala.

OBJECTIVE To assess the test-retest reliability of the 10-step stair ascent test, Timed Up and Go (TUG) test, and 10-meter walking test under dual-task conditions in patients with fibromyalgia. DESIGN Test-retest reliability. SETTINGS Local fibromyalgia association and university facilities. PARTICIPANTS Thirty-eight women with fibromyalgia. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Fear of falling and the number of falls in the last year were measured using a visual analogue scale. The 10-step stair ascent test, TUG test, and 10-meter walking test were conducted under single- and dual-task conditions. The order between single- and dual-task condition was randomized in both test and retest. Retest measurement was assessed the week following the test. RESULTS The reliability of the performance on the 10-step stair ascent test under dual and single conditions ranged between good (>0.75 to

Background: Childhood obesity has negative impact on heart-rate variability (HRV) and, thereby, on the cardiovascular health of children and adolescents. Thus, physical-exercise interventions were proposed to increase HRV. The present systematic review aims to provide an up-to-date analysis of research on the effect of physical-exercise interventions on HRV in obese children and adolescents. Methods: An electronic search of the literature was performed, and 10 articles were included. PRISMA guideline methodology was employed. Results: Physical-exercise interventions predominantly involved aerobic training; however, alternative training programs, including judo or recreational soccer, were found. The duration of intervention ranged from 6 to 24 weeks, with a training frequency of between 2 and 7 times per week. The duration of sessions typically ranged from 40 to 60 min. Conclusions: Results of the included articles indicated that physical-exercise intervention increased the HRV and thereby the autonomic modulation of obese children and adolescents. This is significant, as HRV is associated with cardiovascular health. Such physical-exercise interventions are crucial to reduce weight and improve cardiovascular health in children and adolescents, thereby achieving a sustainable future.

Fibromyalgia is a syndrome that is characterized by widespread pain; fatigue; stiffness; reduced physical fitness; sleep disturbances; psychological symptoms, such as anxiety and depression; and deficits in cognitive functions, such as attention, executive function, and verbal memory deficits. It is important to analyze the potentially different performance on the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) test in patients with fibromyalgia as well as examine the relationship of that performance with physical and cognitive performance. A total of 36 women with fibromyalgia participated in the study. Participants completed the MoCA test, the MMSE, and the TUG physical fitness test under dual-task conditions. The results obtained on cognitive tests were 28.19 (1.74) on the MMSE and 25.17 (2.79) on the MoCA. The participants’ performance on cognitive tests was significantly related to the results of the TUG dual-task test. In this way, cognitive performance on a dual-task test can be used to support the diagnosis of cognitive impairment in patients with fibromyalgia. The MoCA test may be a more sensitive cognitive screening tool than the MMSE for patients with fibromyalgia.

The present study aimed to: (1) analyze the test&ndash, retest reliability of the 30 s chair stand test and the 30 s arm curl test under dual-task conditions, (2) analyze the test&ndash, retest reliability of a new variable which assesses the total performance (cognitive + physical) in both tests. A total of 37 women with fibromyalgia participated in the study. Participants completed the 30 s arm curl test and 30 s chair stand test in both simple and dual-task conditions. These tests were repeated after seven days. In the 30 s chair stand dual-task test the reliability was low to good whereas that of the total performance variable was low to moderate. The reliability in both the 30 s arm curl dual-task test and the total performance variable were good to moderate. Both the 30 s chair stand test and 30 s arm curl test under dual-task conditions and the total performance variables had good test&ndash, retest reliability. However, it is necessary to consider the fluctuations of the intraclass correlation coefficient (ICC).
