Background: Integrating aerobic exercise (AE) into rehabilitation programs for post-stroke individuals could enhance motor recovery and cardiovascular health by increasing brain-derived neurotrophic factor (BDNF) and the myokine irisin. Chronic stroke survivors typically exhibit elevated matrix metalloproteinase-9 (MMP-9) activity, which is negatively correlated with steps and time in medium cadence, although the impact of AE on this biomarker remains unclear.

Objective: To evaluate the effect of high-intensity AE training prior to modified constraint-induced movement therapy (mCIMT) on BDNF and irisin concentration, and on MMP-2 and MMP-9 activity in chronic post-stroke individuals and to associate these results with functional improvements.

Cognitive fatigue (CF) increases accident risk reducing performance, especially during complex tasks such as driving. We evaluated whether transcranial random noise stimulation (tRNS) could mitigate CF and improve driving performance. In a double-blind study, thirty participants performed a virtual reality truck driving task during real ( = 15) or sham ( = 15) tRNS applied bilaterally on the "anti-fatigue network".

Article Synopsis
  • - The study investigates how spaceflights affect intracranial compliance (ICC) and the relationship between cardiorespiratory fitness and the P2/P1 ratio of intracranial pressure waveforms during microgravity conditions (simulated by a head-down tilt position).
  • - Involving 34 participants who underwent cardiopulmonary exercise testing to assess their fitness levels, the study measured P2/P1 ratios using a non-invasive sensor during a 30-minute head-down tilt.
  • - Results showed a negative correlation (-0.388) between cardiorespiratory fitness (measured by peak oxygen uptake) and the P2/P1 ratio, suggesting improved fitness might lead to better ICC in simulated weightlessness.

The microgravity environment has a direct impact on the cardiovascular system due to the fluid shift and weightlessness that results in cardiac dysfunction, vascular remodeling, and altered Cardiovascular autonomic modulation (CAM), deconditioning and poor performance on space activities, ultimately endangering the health of astronauts. This study aimed to identify the acute and chronic effects of microgravity and Earth analogues on cardiovascular anatomy and function and CAM. CINAHL, Cochrane Library, Scopus, Science Direct, PubMed, and Web of Science databases were searched.

Intracranial compliance (ICC) has been studied to complement the interpretation of intracranial pressure (ICP) in neurocritical care and help predict brain function deterioration. It has been reported that ICC is related to maintaining ICP stability despite changes in intracranial volume. However, this has not been properly translated to clinical practice.

Introduction: Upper limb movements are affected frequently by brain ischemia (BI). Mechanisms involved in recovery and compensatory movements have developed several studies. However, less attention is given to skeletal muscles, where neuromuscular junction (NMJ) has an important role on muscle tropism and functional performance.
