Randomised controlled trail

Michele Biasutti, Anthony Mangiacotti
OBJECTIVES: In a randomised controlled trial, we investigated whether a cognitive training based on rhythm-music and music improvisation exercises had positive effects on executive functions in older participants. METHODS: Thirty-five residents in a guest home with mild-moderate cognitive impairment and healthy ageing were randomly assigned to an experimental group (n = 18) featuring cognitive music training composed of 12 bi-weekly 70-min sessions, and a control group (n = 17) attended 12 bi-weekly 45-min sessions of gymnastic activities offered by the institute...

BACKGROUND: Exercise interventions to prevent dementia and delay cognitive decline have gained considerable attention in recent years. Human and animal studies have demonstrated that regular physical activity targets brain function by increasing cognitive reserve. There is also evidence of structural changes caused by exercise in preventing or delaying the genesis of neurodegeneration. Although initial studies indicate enhanced cognitive performance in patients with mild cognitive impairment (MCI) following an exercise intervention, little is known about the effect of an extensive, controlled and regular exercise regimen on the neuropathology of patients with MCI...

BACKGROUND: The REVASCAT trial and other studies have shown that the neurovascular thrombectomy improves outcomes at 90 days post stroke. However, whether the observed benefit is sustained in the long term remains unknown. We report the results of the prespecified 12-month analysis of the REVASCAT trial. METHODS: Patients with acute ischaemic stroke who could be treated within 8 h of symptom onset were randomly assigned to medical therapy (including intravenous alteplase when eligible) and neurovascular thrombectomy with Solitaire FR or medical therapy alone...

INTRODUCTION: Strong evidence shows that exercise is effective to improve fall risk factors among older people. However, older people's participation and adherence to exercise programmes is suboptimal. Type of exercise and apathy are reported to be barriers to exercise participation, suggesting that new effective interventions are needed. The primary aim of this randomised controlled trial is to investigate the effect of Senior Dance plus brief education for falls prevention on balance among people aged 60 years or over, compared with a control group receiving only brief education...

High levels of cardiovascular fitness and physical activity are associated with higher levels of cognitive function in people with HIV, thus, they may reduce the risk of developing HIV-associated neurocognitive disorder (HAND). This study aimed to investigate the effects of a 16-week aerobic exercise intervention on cognitive function in people with HIV. Eleven participants living with HIV were recruited into the study. Participants were randomised into either an exercise group (n = 5), that completed a 16-week aerobic exercise programme training, 3 times per week (2 supervised sessions and one unsupervised session) or a control group (n = 6) that received no intervention...

BACKGROUND: The prevention of falls among older people is a major public health challenge. Exercises that challenge balance are recognized as an efficacious fall prevention strategy. Given that small-scale trials have indicated that diverse dance styles can improve balance and gait of older adults, two of the strongest risk factors for falls in older people, this study aimed to determine whether social dance is effective in i) reducing the number of falls and ii) improving physical and cognitive fall-related risk factors...

BACKGROUND: Femoroacetabular impingement (FAI) and accompanying pathologies are associated with pain and reduced quality of life. Physical impairments can be associated with worse symptoms and may be an important target of rehabilitation programmes in this patient group. Knowledge regarding physical impairments in individuals with symptomatic FAI is limited. HYPOTHESIS: In adults aged 18-50 years with symptomatic FAI, to: (1) identify physical impairments in range of motion (ROM), hip muscle function and functional tasks; (2) to compare physical impairments with healthy controls; and (3) to evaluate the effects of interventions targeting physical impairments...

BACKGROUND: An anatomical reconstruction of the ankle congruity is the important prerequisite in the operative treatment of acute ankle fractures. Despite anatomic restoration patients regularly suffer from residual symptoms after these fractures. There is growing evidence, that a poor outcome is related to the concomitant traumatic intra-articular pathology. By supplementary ankle arthroscopy anatomic reduction can be confirmed and associated intra-articular injuries can be treated. Nevertheless, the vast majority of complex ankle fractures are managed by open reduction and internal fixation (ORIF) only...

Children with a diagnosis of autism are more likely to experience anxiety than their typically developing peers. Research suggests that Cognitive Behavioural Therapy (CBT) could offer a way to help children with autism manage their anxiety but most evidence is based on clinical trials. This study investigated a school-based CBT programme using a quasi-experimental design incorporating the child and parent versions of the Spence Children's Anxiety Scale (Spence, J Abnorm Psy 106(2):280-297, 1997) and the Coping Scale for Children and Youth (Brodzinsky et al...

BACKGROUND: This methodological paper presents both a scientific rationale and a methodological approach for investigating the effects of resveratrol supplementation on mood and cognitive performance in postmenopausal women. Postmenopausal women have an increased risk of cognitive decline and dementia, which may be at least partly due to loss of beneficial effects of estrogen on the cerebrovasculature. We hypothesise that resveratrol, a phytoestrogen, may counteract this risk by enhancing cerebrovascular function and improving regional blood flow in response to cognitive demands...

INTRODUCTION: Most studies conducted at general practices investigate complex interventions and increasingly use cluster-randomised controlled trail (c-RCT) designs to do so. Our primary objective is to evaluate how frequently complex interventions are shown to be more, equally or less effective than routine care in c-RCTs with a superior design. The secondary aim is to discover whether the quality of a c-RCT determines the likelihood of the complex intervention being effective. METHODS AND ANALYSIS: All c-RCTs of any design that have a patient-relevant primary outcome and with a duration of at least 1 year will be included...
