- Abstract
- Background High Velocity Thrust (HVT) techniques are widely used in osteopathic treatment. of somatic and visceral dysfunction. Research has demonstrated the existence .of somato-visceral and viscero-somatic reflex interactions but to date the neurophysiological mechanisms of the effects of HVT are not well understood. There has been little research investigating the effects of osteopathic spinaL manipulation on visceral function. HVT has been shown to influence the autonomic nervous system (ANS), apparently by stimulating sympathetic reflexes, which alter function in the viscera or vasculature. Changes in vasomotor activity are mediated by the sympathetic nervous system (SNS) and it is considered that measuring changes in cutaneous blood flow (CBF) provides a valid reflection of SNS activity. Laser Doppler Flowmetry provides continuous measurement of cutaneous microvascular blood perfusion. It is non-invasive, non-injurious. and does not affect the local blood perfusion. It is convenient for recordingrelative intra-subject changes in blood flow in response to graded stimuli Methods CBF at the dorsal aspect of both wrists was monitored in twenty asymptomatic, male osteopathic students of similar age and body mass index. CBF was recorded for an initial 5-minute 'control' period with the subject at rest. This was followed by a 'sham HVT' to the cervical spine which involved 'setting up' the subject's cervical spine as if to carry out an HVT in right rotation at C6 but without actually thrusting. CBF was recorded for another 5 minute period before an actual HVT was applied at C6. This was followed by a final 5 minute recording period. Results The results showed that there was no significant difference in CBF between the 'control' and 'post sham HVT' readings but a significant decrease (p
