Effect of spinal cord injury and its lesion level on stretch reflex modulation by cold stimulation in humans

摘要: Abstract Objective To determine how short-latency stretch reflex amplitude in the soleus muscle is modulated by cold stimulation able-bodied individuals and with complete spinal cord injury. Methods An initial 100-s baseline period was followed 50-s periods. Stretch of right elicited for 10-s intervals, while applied to left thigh. Results Peak-to-peak increased significantly during up 127 ± 21% group ( n  = 9, P  = 4), although this increase not significant. On other hand, decreased down 78 ± 20% a injury level at or above thoracic 6  = 8, Conclusions Effect afferent inputs induced on modulation different depending extent central nervous systems participating modulation. Significance Our findings provide better understanding some basic changes afferent–efferent pathways which are probably monosynaptic nature.
