Tonic vibration reflex in spasticity, Parkinson's disease, and normal subjects.
The tonic vibration reflex (TVR) has been studied in the quadriceps and triceps surae muscles of 34 spastic, 15 Parkinsonism, and 10 normal subjects. The TVR of spasticity develops rapidly, reaching a plateau level within 2-4 sec of the onset of vibration. The tonic contraction was often preceded by a phasic spike which appeared to be a vibration-induced equivalent of the tendon jerk. The initi...
متن کاملAsymmetric tonic neck reflex and symptoms of attention deficit and hyperactivity disorder in children.
One of the particularly important postnatal developmental reflexes that diminish in later stages of development is asymmetric tonic neck reflex (ATNR), which belongs among the so-called primitive reflexes. According to current evidence, certain later developed functions during ontogenesis of the central nervous system tend to replace the primitive reflexes, and their persistence is related to c...
متن کاملA CODlparative Study on the Presence of the ASYDlDletrical Tonic Neck Reflex in Adult
In this study, the intensity of the asymmetrical tome neck reflex (ATNR) was measured in post-cerebrovascular accident (CVA) adults with hemiplegia and in neurologically intact adults to determine if the reflex exaggerated following CVA. Fourteen subjects with right and left hemiplegiC! were matched to neurologically intact subjects by age and sex and tested for the ATNR. Intensity of the refle...

متن کاملInteraction between voluntary contraction and tonic stretch reflex transmission in normal and spastic patients.
Transmission characteristics of tonic stretch reflex (TSR) pathways in both normal and spastic patients have been measured during different levels of sustained voluntary contraction of the biceps brachii muscle. A cross-correlation technique of analysis was used to separate reflex responses from the total electromyographic activity. TSR transmission in normal subjects was observed to change wit...
