Affective and autonomic response to dynamic rhythmic entrainment: Mechanisms of a specific music therapy factor

The objective of this study was to examine specific cardiovascular and affective effects of live music matched with the listener’s heart beat, with the tempo gradually decreased to assess the relaxation effect.Thirty apparently healthy students were randomized to either the experimental (EG) or the control group (CG). After a brief mental stress task, both groups listened to a live music therapy relaxation technique. While a biofeedback device was utilized to enable real-time synchronization of relaxing music to the listener’s pulse in the EG, the tempo in the CG was fixed to 70 beats per minute. Self-ratings of stress and well-being, as well as autonomic measures of cardiovascular reactivity were assessed.The entrained-tempo condition led to a significantly stronger increase in peripheral blood flow (p   .05).We conclude that rhythmic entrainment may promote a psychophysiological relaxation response. The decrease in sympathetic arousal may have led to more favorable affective self-ratings via an interoceptive feedback process, but more research is needed to clarify the direction of effects.

ConclusionThe VEMPs and vHIT tests demonstrated that there is no evidence of hypofunction of the semicircular canals in the high-frequency spectrum of VOR functioning. Nor are there any indications of impairment of the otolith system in patients with PD, regardless of their subjective vestibular sensations. The findings of the current study confirm the proposed link between anxiety, panic symptoms and postural instability in PD patients.

Objective: Electrical impedance myography (EIM) is a quantitative and objective tool to evaluate muscle status. EIM offers the possibility to replace conventional physical functioning scores or quality of life measures, which depend on patient cooperation and mood. Methods: Here, we propose a functional mixed-effects model using a state-space approach to describe the response trajectories of EIM data measured on 16 boys with Duchenne muscular dystrophy and 12 healthy controls, both groups measured over a period of two years. The modeling framework presented imposes a smoothing spline structure on EIM data collected at each...

Int J Sports Med DOI: 10.1055/a-0783-2581Offering large muscle benefits despite low metabolic demand, continuous eccentric exercise appears to be an interesting alternative to concentric exercise. Nevertheless, further knowledge is needed about prolonged eccentric exercise. This work sought to investigate the cardiovascular responses to prolonged constant-load eccentric compared to concentric cycling. Ten healthy males performed two 45-min exercise sessions of either concentric or eccentric cycling separated by a month and matched for heart rate during the first 5 min of exercise. Cardiorespiratory, autonomic nervou...

AbstractObjectiveTo observe the imbalance of anatomical and functional innervation factors of sympathetic nerves, nerve growth factor (NGF) and leukemia inhibitory factor (LIF), in salt-sensitive hypertensive heart failure rats and to explore the effects of treatment with Guizhi Decoction ( 桂枝汤) on sympathetic remodeling by inhibiting cholinergic transdifferentiation.MethodsSS-13BN and Dahl salt-sensitive (DS) rats were divided into 3 groups: SS-13BN group (control group,n=9), DS group (model group,n=9) and GS group (Guizhi Decoction,n=9). After 10 weeks of a high-salt diet, the GS group rats were given Guizhi Decoct...

AbstractBackgroundSympathetic neural activation plays a key role in the incidence and maintenance of acute myocardial infarction (AMI) induced ventricular arrhythmia (VA). Furthermore, previous studies showed that AMI might induce microglia and sympathetic activation and that microglial activation might contribute to sympathetic activation. Recently, studies showed that light emitting diode (LED) therapy might attenuate microglial activation. Therefore, we hypothesized that LED therapy might reduce AMI ‐induced VA by attenuating microglia and sympathetic activation.MethodsThirty anesthetized rats were randomly divided in...

Abstract In memory research, studying cerebellum-dependent memory is advantageous due to its relatively simple neural architecture compared with that of other memory circuits. To understand how cerebellum-dependent memory develops and is stored in this circuit, numerous hypotheses have been proposed. These hypotheses are generally able to adequately explain most learning and memory processes; however, several reported results are still poorly understood. Recently, the importance of intrinsic plasticity (i.e., plasticity of intrinsic excitability) has been highlighted in several studies. Because the classical view ...
