OBJECTIVE:   The aim of the current study was to investigate changes in the intrinsic inhibitory interactions within the somatosensory system subsequent to a session of spinal manipulation of dysfunctional cervical joints.

METHOD:   Dual peripheral nerve stimulation somatosensory evoked potential (SEP) ratio technique was used in 13 subjects with a history of reoccurring neck stiffness and/or neck pain but no acute symptoms at the time of the study. Somatosensory evoked potentials were recorded after median and ulnar nerve stimulation at the wrist (1 millisecond square wave pulse, 2.47 Hz, 1 x motor threshold). The SEP ratios were calculated for the N9, N11, N13, P14-18, N20-P25, and P22-N30 peak complexes from SEP amplitudes obtained from simultaneous median and ulnar (MU) stimulation divided by the arithmetic sum of SEPs obtained from individual stimulation of the median (M) and ulnar (U) nerves.

RESULTS:   There was a significant decrease in the MU/M + U ratio for the cortical P22-N30 SEP component after chiropractic manipulation of the cervical spine. The P22-N30 cortical ratio change appears to be due to an increased ability to suppress the dual input as there was also a significant decrease in the amplitude of the MU recordings for the same cortical SEP peak (P22-N30) after the manipulations. No changes were observed after a control intervention.

World Spine Day – October 16th, 2015

World Spine Day is a part of the Bone and Joint Decade Action Week which occurs each year in October. The 16th of October is the day dedicated as World Spine Day.

The theme “Straighten Up and Move” was introduced in 2012 and emphasized the importance of healthy spinal posture and activity which promote body awareness and minimizes the day-to-day wear and tear on a person’s spine. The theme of posture and movement supports the BJD’s Vision of “Keep People Moving”. The intent of WSD is to bring people from all walks of life – patients, health providers, health care organizations, associations and governments to help ease this global burden.

The aims of WSD:

  1. Raise awareness about spinal health and spine disorders within the interdisciplinary health care community and amongst public policy decision-makers and the general public;
  2. To provide an opportunity for and encourage ongoing discussion about the burden of spinal disorders; and
  3. To promote an interdisciplinary, collaborative approach to easing the burden of spinal disorders.

WSD Theme 2015- “Your Back at Work”

In 2015 a new theme is being introduced for WSD- “Your Back at Work”.  It is anticipated that this theme will continue for the next 2-3 years, building on the “Straighten Up and Move” theme.

Prevention, education and management of spine disorders in the workplace are of utmost importance and this year’s theme provides an important opportunity to highlight the importance of global, regional and local initiatives to address the burden of MSK disorders in the workplace.
