Joint mobilization (JM), such as lateral glides (LAT) and posterior pressures (AP) appears efficacious for non-specific neck pain (NSNP). The neurophysiologic system that modulates pain overlaps with blood pressure (BP) as observed in BP-related hypoalgesia. Nevertheless, evidence is sparse characterizing the cardiovascular response (CR) to LAT or AP in NSNP. Five sets of (10 seconds on and 10 seconds off) AP and LAT have evidently produced disparate cardiovascular responses in pain-free adults. What is indeterminate is whether these procedures, when dispensed in the same minimal regimen, yield comparable or divergent outcomes in patients with
NSNP.
Our study aspires to explore whether AP or LAT: (1) is more effective in altering neck disability, pain, range of

Ten participants (5 females; mean age of 26.8 ± 8.6) with unilateral NSNP were recruited from two universities.
A research assistant randomly allocated each individual to 1 of 2 groups. Both Group 1: AP and Group 2: LAT obtained posterior pressures and lateral glides respectively to the most tender and restricted segment. An assistant collected baseline numeric pain rating scale (NPRS), and Neck Disability Index (NDI) at the initial session. An OMRON automatic monitor measured the systolic blood pressure (SBP) and heart rate (HR) with recording time points: (1) 5 minutes, and
(2) 7 minutes after lying supine; (3) during the 1st set, (4) 5th set of one of the glides, (5) 2 minutes after time point #4, and (6) 4 minutes after time point #4. Following time point #6, the assistant gathered a global rating of change (GROC) based on the cervical spine and shoulder motion reexamination. Blinded to the random allocation and collected data, the primary author performed one of the techniques on all participants. Within 1 week, follow-up NPRS, and NDI were
