Pain intensity was assessed using the visual analog scale (VAS), and cervical ROM was measured in multiple directions before and immediately after the intervention.<br> <strong>Results</strong>: Both intervention groups (TE and TEKE) showed significant improvements in pain reduction and cervical ROM compared to the control group (P<0.05). However, no statistically significant differences were found between the TE and TEKE groups in either outcome, suggesting comparable effectiveness. These findings indicate that TE-based SMR alone may be highly effective in managing neck pain and improving mobility.<br> <strong>Conclusion</strong>: SMR with a TE is an effective and low-cost intervention to reduce neck pain and increase cervical ROM in women with nonspecific chronic neck pain. The addition of Kinesio taping did not yield additional benefits. This method offers a practical self-management strategy that can be easily implemented in both clinical and home settings. Further studies are warranted to evaluate its long-term application and broad clinical relevance.</div> Neck pain, Myofascial release, Kinesio taping, Range of motion, Musculoskeletal manipulations 445 452 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-724-1&slc_lang=en&sid=1 Vahid Mazloum Vahid.mazloum@yahoo.com 0000-0001-7524-3400 No Department of Sport Injuries and Corrective Exercises, Ka.
