Systolic Blood Pressure Response to Laterally Directed Pressure Applied to the Cervical Spine – A Randomized, Repeated-Measures, Double Blind, Placebo-Controlled Study
Background: The neurophysiologic system that modulates pain overlaps with blood pressure (BP) as observed in BP-related hypoalgesia. Cervical spine (CS) posterior pressure (AP) was shown to decrease systolic BP (SBP) while lateral glides (LAT) in the upper limb neurodynamic test (ULNT) position, LAT+ULNT, increased SBP. CS LAT appears effective for cervical radiculopathy. However, the cardiovascular response to LAT alone is unknown and many patients early on may only tolerate LAT but not LAT + ULNT.
