A vagal maneuver is an action used to stimulate the parasympathetic nervous system by activating the vagus nerve. The vagus nerve is the longest nerve of the autonomic nervous system and helps regulate many critical aspects of human physiology, including heart rate, blood pressure, sweating, and digestion through the release of acetylcholine .
Vagal tone research has the potential to offer insight into social behavior, social interactions, and human psychology. Much of this work has been focused on newborns and children . [ 26 ] Baseline vagal tone can be used either as a potential predictor of behavior or as a signal of mental health (particularly emotion regulation , anxiety , and ...

Rigidity is a nonselective increase in the tone of agonist and antagonist without velocity dependence, and the increased tone remains uniform throughout the range of movement. On the contrary, spasticity is a velocity-dependent increase in tone resulting from the hyper excitability of stretch reflexes. [ 7 ]
When you first begin with the dumbbell exercises, start with 3-pound weights and work your way up to 5 or even 8 pounds. I recommend a medium-strength resistance with the resistance bands.
Vagovagal reflex refers to gastrointestinal tract reflex circuits where afferent and efferent fibers of the vagus nerve [1] coordinate responses to gut stimuli via the dorsal vagal complex in the brain. The vagovagal reflex controls contraction of the gastrointestinal muscle layers in response to distension of the tract by food.
The reflex was originally demonstrated by Bainbridge in 1915 who observed an increase in heart rate following infusion of blood or saline into the jugular vein of anaesthetized dogs. [6] The response was reduced by cutting the cardiac sympathetic nerves and abolished by cutting the vagus nerve and he therefore concluded that it was a neural reflex.
