Abstract. [Purpose] To investigate effects of thoracic manipulation versus mobilization on chronic neck pain.
[Methods] Thirty-nine chronic neck pain subjects were randomly assigned to single level thoracic manipulation,
single level thoracic mobilization, or a control group. The cervical range of motion (CROM) and pain ratings (using
a visual analog scale: VAS) were measured before, immediately after and at a 24-hour follow-up. [Results] Thoracic
manipulation significantly decreased VAS pain ratings and increased CROM in all directions in immediate and 24-
hour follow-ups. The thoracic mobilization group significantly increased in CROM in most directions at immediate
follow-up and right and left rotational directions at the 24-hour follow-up. Comparisons between groups revealed
the CROM for the manipulation group to increase significantly more than for control subjects in most directions
at immediate follow-up and flexion, left lateral flexion and left rotation at the 24-hour follow-up. The CROM for
the thoracic mobilization group significantly increased in comparison to the control group in flexion at immediate
follow-up and in flexion and left rotation at the 24-hour follow-up. [Conclusion] The study demonstrated reductions
in VAS pain ratings and increases in CROM at immediate and 24-hour follow-ups from both single level thoracic
spine manipulation and thoracic mobilization in chronic neck pain.
