The Effects of Spinal Manipulation on Central Integration of Dual Somatosensory Input Observed After Motor Training: A Crossover Study

The Effect of Cervical Spine Manipulation on Postural Sway in Patients With Nonspecific Neck Pain

“…Instead, there was a significant decrease in the MU:M+U ratio for the cortical N30 SEP component. The ratio changes appear to be due to an improved ability to suppress the dual input as concurrent changes in the MU amplitudes were observed (Haavik-Taylor & Murphy, 2010b).…”

“…Surround, or lateral inhibition is a mechanism by which the nervous system amplifies information from one area by reducing the excitability of adjacent areas (Haavik-Taylor & Murphy, 2010b). This acts to enhance the contrast between different stimuli, for example borders between colours and contours on objects.…”

Subclinical Neck Pain and the Effects of Cervical Manipulation on Elbow Joint Position Sense

“…[1][2][3][4][5][6][7][8][9][10][11][12] However, it is less certain whether these observed changes in central nervous system (CNS) processing reflect clinically beneficial changes to the individual participants. It has been suggested that these observed changes in sensory processing, sensorimotor integration, and motor control could reflect a mechanism that explains the functional improvements observed after chiropractic care.…”

“…It has been suggested that these observed changes in sensory processing, sensorimotor integration, and motor control could reflect a mechanism that explains the functional improvements observed after chiropractic care. 6,10,12,13 Our group has proposed that high-velocity, low-amplitude manipulation has a neuromodulatory effect on CNS function. 13 Furthermore, we have proposed that segments of the spine where the movement is functionally restricted in at least 1 plane may represent an ongoing state of altered afferent input that could induce maladaptive neuroplastic changes.…”

“…13 Furthermore, we have proposed that segments of the spine where the movement is functionally restricted in at least 1 plane may represent an ongoing state of altered afferent input that could induce maladaptive neuroplastic changes. 6,10,12,13 The functional segmental restriction could involve restriction in the coronal plane, such as reduced lateral flexion motion, or could include restriction of appropriate movement in the sagittal plane, such as decreased flexion or extension movement. This functional putative manipulable lesion is known by a variety of terms such as joint dysfunction, fixation, or subluxation.…”
