The effects of hyperventilation on postural control mechanisms.
The effect of hyperventilation on postural balance was investigated. Voluntary hyperventilation increased body sway in normal subjects, particularly in the sagittal plane. The possibility that this hyperventilation-induced unsteadiness is due to interference with lower limb somatosensory input, vestibular reflexes or cerebellar function was assessed. (i) The effect of hyperventilation on periph...
متن کاملEffects of chlorpromazine on spinal cord reflex mechanisms.
-The effects of chlorpromazine (CPZ) on the patellar reflex and segmentally evoked spinal cord potentials were determined in the high spinal and hemiscctioned spinal cat preparations. CPZ in doses of 1-32 mg/kg given intravenously (as an accumulative dose) produced no statistically significant alteration of the patellar reflex and segmentally evoked monosynaptic potentials. The segmentally evok...
متن کاملEffects of postural changes of the upper limb on reflex transmission in the lower limb. Cervicolumbar reflex interactions in man.
The influence of passive changes in upper limb position on the excitability of three myotatic arc reflexes (soleus, quadriceps, and biceps femoris) of the lower limb has been explored on 42 volunteers. The results indicate that the excitability of the three myotatic arcs can be influenced at a distance by postural modifications of the upper limb. When the ipsilateral upper limb is forwards or t...
متن کاملMechanical effects of pharyngeal constrictor activation on pharyngeal airway function.
The mechanical effects of pharyngeal constrictor (PC) muscle activation on pharyngeal airway function were determined in 20 decerebrate, tracheotomized cats. In 10 cats, a high-compliance balloon attached to a pressure transducer was partially inflated to just occlude the pharyngeal airway. During progressive hyperoxic hypercapnia, changes in pharyngeal balloon pressure were directly related to...
متن کاملNeurophysiology of Postural Mechanisms
undertaken! Imbalances in presentation are exemplified by the treatment of Bacteroides (just a half-page) whilst Myco leprae fills more than two pages. On p.315 the multiple pressure method of smallpox vaccination is said to be a special procedure! On p.47 the brief paragraph on 'Droplets' frightens the reviewer-it is non-informed and tells the reader nothing of significance of large droplets c...
