mechanoreceptors of foot sole likely contribute in the reflex regulations. stimulation of these receptors in the lateral aspect of the foot is corresponded to the lateral plantar division of the tibial nerve. therefore, it was hypothesized that repetitive low threshold afferents stimulation would have an inhibitory effect on the soleus h-reflexes. methods: sixteen normal subjects voluntarily pa...

The plantar grasp reflex is of great clinical significance, especially in terms of the detection of spasticity. The palmar grasp reflex also has diagnostic significance. This grasp reflex of the hands and feet is mediated by a spinal reflex mechanism, which appears to be under the regulatory control of nonprimary motor areas through the spinal interneurons. This reflex in human infants can be r...

Recent studies indicate that rats can increase or decrease H-reflex amplitude in response to an operant conditioning paradigm. In addition, rats also display a circadian rhythm in H-reflex amplitude. As part of the development of H-reflex conditioning in the rat as a new model for defining the plasticity underlying a simple form of learning, this study examined the relationship in the rat betwe...

The Hoffmann (H-) reflex is an electrical analogue of the monosynaptic stretch reflex, elicited by bypassing the muscle spindle and directly stimulating the afferent nerve. Studying H-reflex modulation provides insight into how the nervous system centrally modulates stretch reflex responses.A common measure of H-reflex gain is the slope of the relationship between H-reflex amplitude and EMG amp...

Moderate rectal distension elicits recto-rectal reflex contractions and simultaneous recto-internal anal sphincter reflex relaxations that together comprise the defecation reflex. Both reflexes are controlled by 1) pelvic nerves, 2) lumbar colonic nerves, and 3) enteric nervous system. The aim of the present study was to explore a novel approach to repairing the defecation reflex dysfunction by...

Heart rate variability biofeedback (HRV BFB) is paced breathing scheme that stimulates resonance in the cardiovascular system. This study aimed to investigate effect of a single-session HRV BFB on Hoffman reflex (H-reflex) soleus muscle. Twelve healthy males (height: 173.7 ± 7.18 cm; weight: 72.7 17.7 kg; age: 24.0 5.02 yrs) completed randomized-crossover intervention involving 10-minute and no...

The organizational reflex in relation to the company is considered be an instinctive reaction of its employees external stimulus that has arisen or, other words, ability employee spontaneously generate a competitive response based on information received from global environment. It intentional algorithm enables know how and when react as quickly possible, according signal environment received, ...

In 30 normal subjects, the influence of the reflex activation of one myotatic reflex arc on the excitability of other myotatic reflex arcs of the lower limb has been investigated using excitability curves. Soleus, quadriceps, and short biceps tendon reflexes as well as H reflex at two different intensities (liminal and H max/2) were used either as conditioning or as conditioned responses. The r...
