Effects of contraction and lactic acid on the discharge of group III muscle afferents in cats.
1. In barbiturate-anesthetized cats we examined the interaction of lactic acid and static contraction on the discharge of group III muscle afferents. Only afferents whose receptive fields wereExpand

Spinal manipulation alters electromyographic activity of paraspinal muscles: a descriptive study.
OBJECTIVE To examine the effect of spinal manipulation on electromyographic (EMG) activity in areas of localized tight muscle bundles of the low back. METHODS Surface EMG activity was collectedExpand

Response of muscle proprioceptors to spinal manipulative-like loads in the anesthetized cat.
OBJECTIVE The mechanisms underlying the benefits of spinal manipulation are not well understood. Neurophysiological mechanisms likely mediate its effects, at least in part, yet we know little aboutExpand

Paraspinal muscle spindle responses to the duration of a spinal manipulation under force control.
OBJECTIVE More than 90% of chiropractic patients receive high-velocity, low-amplitude spinal manipulation (HVLA-SM) as part of their chiropractic care. The purpose of the current study was determineExpand

Skeletal muscle ouabain binding sites are reduced in rats with chronic heart failure.
Intrinsic skeletal muscle abnormalities decrease muscular endurance in chronic heart failure (CHF). In CHF patients, the number of skeletal muscle Na(+)-K(+) pumps that have a high affinity forExpand

Response of lumbar paraspinal muscles spindles is greater to spinal manipulative loading compared with slower loading under length control.
BACKGROUND CONTEXT Spinal manipulation (SM) is a form of manual therapy used clinically to treat patients with low back and neck pain. The most common form of this maneuver is characterized as aExpand

Effect of Spinal Manipulation Duration on Low Threshold Mechanoreceptors in Lumbar Paraspinal Muscles: A Preliminary Report
Study Design. Electrophysiologic recordings were obtained from low threshold primary afferent neurons innervating lumbar multifidus and longissimus muscles in the anesthetized cat. Objective. TheExpand

Discharge properties of group III and IV muscle afferents.
Stimulation of group III and IV muscle afferents has been shown to have important reflex effects on both the somatic and autonomic nervous systems. These include an inhibitory effect on alphaExpand

Spinal manipulative therapy and somatosensory activation.
Manually-applied movement and mobilization of body parts as a healing activity has been used for centuries. A relatively high velocity, low amplitude force applied to the vertebral column withExpand
