Simultaneous characterizations of reflex and nonreflex dynamic and static changes in spastic hemiparesis.
This study characterizes tonic and phasic stretch reflex and stiffness and viscosity changes associated with spastic hemiparesis. Perturbations were applied to the ankle of 27 hemiparetic and 36 healthy subjects under relaxed or active contracting conditions. A nonlinear delay differential equation model characterized phasic and tonic stretch reflex gains, elastic stiffness, and viscous damping...
متن کاملUse of a hand-held dynamometer and a Kin-Com dynamometer for evaluating spastic hypertonia in children: a reliability study.
BACKGROUND AND PURPOSE Studies in subjects with spastic hypertonia indicate that the higher resistance to stretch in the spastic muscles is not only due to hyperactive stretch reflexes but also to changes in the muscle-tendon unit (nonreflex components). The aim of this study was to compare the test-retest reliability of two methods: hand-held dynamometry and isokinetic dynamometry for the eval...
متن کاملAltered excitability of the crayfish lateral giant escape reflex during agonistic encounters.
The excitability of the lateral giant escape reflex of socially dominant and submissive crayfish at rest and during agonistic encounters was studied and compared. During agonistic encounters the excitability of the lateral giant reflex falls, substantially in subordinates and slightly in dominants, whereas at rest excitability seems to be independent of social status. Thus, paradoxically, socia...
متن کاملThe Effect of Adding Homeopathic Treatment to Rehabilitation on Abnormal Reflexes of Children with Spastic Cerebral Palsy
Objectives: Cerebral palsy (CP) is a static encephalopathy with abnormal reflexes that cause motor developmental delay. In addition to conventional methods, complementary medicine like homeopathy has been used in treatment of neuro-developmental disorders. This study has been done to determine the effect of adding homeopathic treatment to rehabilitation on abnormal reflexes of children with spa...
متن کاملModulation of stretch reflexes of the finger flexors by sensory feedback from the proximal upper limb poststroke.
Neural coupling of proximal and distal upper limb segments may have functional implications in the recovery of hemiparesis after stroke. The goal of the present study was to investigate whether the stretch reflex response magnitude of spastic finger flexor muscles poststroke is influenced by sensory input from the shoulder and the elbow and whether reflex coupling of muscles throughout the uppe...
