Stretch reflexes of triceps surae in normal man.
In order to learn more about stretch reflex behaviour of triceps surae, normal human subjects sat in a chair with one foot on a platform attached to a torque motor that produced phasic dorsiflexion displacements on the ankle. EMG activity was recorded from triceps surae and responses were obtained for various conditions. When the subjects's foot was relaxed, stretch of triceps surae produced a ...
متن کاملStretch reflexes of triceps surae in patients with upper motor neuron syndromes.
Electromyographic responses of triceps surae to dorsiflexion stretch were studied in 47 patients with a variety of lesions producing an upper motor neuron syndrome. The short latency spinal reflexes, both when the patient was at rest and when he was exerting a voluntary plantarflexion, were frequently enhanced in magnitude and the rate of increase with acceleration was also enhanced. Long-laten...
متن کاملTriceps Surae Short Latency Stretch Reflexes Contribute to Ankle Stiffness Regulation during Human Running
During human running, short latency stretch reflexes (SLRs) are elicited in the triceps surae muscles, but the function of these responses is still a matter of controversy. As the SLR is primarily mediated by Ia afferent nerve fibres, various methods have been used to examine SLR function by selectively blocking the Ia pathway in seated, standing and walking paradigms, but stretch reflex functi...
متن کاملStretch and H reflexes in triceps surae are similar during tonic and rhythmic contractions in high decerebrate cats.
During locomotion in decerebrate and spinal cats the group Ia afferents from hind leg muscles are depolarized rhythmically. An earlier study concluded that this locomotor-related primary afferent depolarization (PAD) does not contribute to modulation of monosynaptic reflex pathways during locomotion. This finding indicated that the neural network generating the locomotor rhythm, the central pat...
متن کاملStretch hyperreflexia of triceps surae muscles in the conscious cat after dorsolateral spinal lesions.
Resistive force and electromyograms from triceps surae muscles were measured during dorsiflexion of both ankles of awake cats before and after interruption of one dorsolateral funiculus (DLF). DLF lesions produced ipsilateral increases in dynamic and static reflex force that persisted over 66 weeks. The increase in dynamic reflex force was velocity sensitive, as demonstrated by a greater effect...
