Training based on mirror visual feedback influences transcallosal communication

Abstract Mirror visual feedback (MVF) therapy has been demonstrated to be successful in neurorehabilitation, probably inducing neuroplasticity changes in the primary motor cortex (M1). However, it is not known whether MVF training influences the hemispheric balance between the M1s. This topic is of extreme relevance when MVF training is applied to stroke rehabilitation, as the competitive interaction between the two hemispheres induces abnormal interhemispheric inhibition (IHI) that weakens motor function in stroke patients. In the present study, we evaluated, in a group of healthy subjects, the effect of motor training and MVF training on the excitability of the two M1s and the IHI between M1s. The IHI from the ‘active’ M1 to the opposite M1 (where ‘active’ means the M1 contralateral to the moving hand in the motor training and the M1 of the seen hand in the MVF training) increased, after training, in both the experimental conditions. Only after motor training did we observe an increase in the excitability of the active M1. Our findings show that training based on MVF may influence the excitability of the transcallosal pathway and support its use in disorders where abnormal IHI is a potential target, such as stroke, where an imbalance between the affected and unaffected M1s has been documented. Mirror visual feedback therapy has been demonstrated to be successful in neuro‚Äźrehabilitation likely inducing neuroplasticity changes in the primary motor c...

Conclusion Swim training, a sport characterized by unique cardiac loading conditions, stimulates eccentric LV remodeling with the concomitant augmentation of systolic twist and diastolic relaxation. This volume-mediated cardiac remodeling appears to result in greater systolic susceptibility to acute afterload challenge. Further work is required to establish how training-induced changes in function translate to human performance and whether these are accompanied by physiologic trade-offs with relevance to common forms of heart disease.

Conclusions The increase in HR rather than an increase in CBF or forearm venous volume was responsible for the decrease in SV during moderate-intensity exercise when Tsk was held at 38°C.

Conclusions After accounting for baseline PA, greater positive changes in leisure-time PA levels were associated with a more eccentric-type of LV remodeling pattern over 10 yr. The clinical implications of such findings remain to be determined.

ConclusionFrequency and impact of vestibular symptoms in patients visiting the ED were higher than previously reported, and life-threatening aetiologies such as strokes are common. Therefore, awareness among physicians regarding the importance of vestibular symptoms has to be improved.

For decades, healthy patients were told to take a low-dose aspirin as a precaution to help prevent heart problems, but the guidelines changed this year. For patients who have had a heart attack, stroke or open heart surgery, a daily aspirin is still recommended and can be a lifesaver. But the blood-thinning effect from aspirin could cause a major bleeding event, so for many healthy patients, the daily aspirin habit was not worth the risk.

(Natural News) Reversible cerebral vasoconstriction syndrome (RCVS) is a rare condition caused by the sudden tightening of blood vessels that supply oxygen to the brain. It is characterized by severe ‘thunderclap’ headaches – with or without neurological symptoms – and in some cases, occasional seizures. RCVS can also lead to ischemic or hemorrhagic stroke. Traditionally, two...

Here Matthew O'Connor of the SENS Research Foundation talks about the research that led to founding of Underdog Pharmaceuticals, a biotech startup incubated by the foundation to commercialize a means of targeting 7-ketocholesterol in atherosclerosis and other conditions. Oxidized cholesterols, and largely 7-ketocholesterol, are the primary cause of dysfunction in the macrophage cells normally responsible for preventing the build up of fatty plaques in blood vessel walls. That dysfunction is the cause of atherosclerosis, and the fact that the presence of oxidized cholesterols increases with age is one of the reasons why ath...
