Effects of static flexion-relaxation on paraspinal reflex behavior.
BACKGROUND Static trunk flexion working postures and disturbed trunk muscle reflexes are related to increased risk of low-back pain. Animal studies conclude that these factors may be related; passive tissue strain in spinal ligaments causes subsequent short-term changes in reflex. Although studies have documented changes in the myoelectric onset angle of flexion-relaxation following prolonged s...
متن کاملSpinal interneurons that are selectively activated during fictive flexion reflex.
Behavioral choices in invertebrates are mediated by a combination of shared and specialized circuitry, including neurons that are inhibited during competing behaviors. Less is known, however, about the neural mechanisms of behavioral choice in vertebrates. The spinal cord can appropriately select among several types of limb movements, including limb withdrawal (flexion reflex), scratching, and ...
متن کاملExteroceptive vibration-induced finger flexion reflex in man.
A tonic finger flexion reflex, induced by mechanical vibration (100 Hz) of the fingers, was studied in 20 healthy subjects. The outcome of nerve blocking experiments indicated that the reflex is mainly exteroceptive, distinct from the tonic vibration reflex of muscle spindle origin. Mechanoreceptors with fast conducting nerve fibres in the distal phalanx seem to constitute the major afferent so...
متن کاملEffects of measurement posture and stimulation intensity on the nociceptive flexion reflex (RIII reflex)
[Purpose] The purpose of this study was to examine the effects of the measurement posture and stimulation intensity on the nociceptive flexion reflex (RIII reflex). [Subjects and Methods] Thirty normal female adult subjects were selected for this study. Their RIII reflexes were measured in three positions and with three degrees of stimulation intensity. The measurement posture was randomly sele...
