Background: Determining appropriate cold laser (CL) parameters in post cervical laminoplasty syndrome (PCLS) is a key challenge in physical therapy practice facing conflicting results. Purpose: The purposes of this study was to compare CL with laser puncture (LP) effect on chronic neck pain using pain intensity numerical rating scale (PI-NRS), cervical kinematics using C2-C7 cobb angle, gold method for cervical sagittal lordotic angle and cervical sagittal range of motion (ROM) and neck disability level using neck pain and disability scale (NPDS) in patients suffering from PCLS. Methods: Sixty participants suffering from PCLS randomly allocated into three groups. Group (A) received conventional physical therapy (isometric strengthening and stabilization) exercises, plus CL (632.8 nm, 24 J/cm2 within tender areas); group (B) received conventional physical therapy exercises, plus LP (632.8 nm, 24 J/cm2 over selected acupoints and control group (C) received conventional physical therapy exercises. All groups received fourteen sessions, twice weekly for seven consecutive weeks. All participants underwent three evaluations of outcomes measures using PI-NRS, NPDS and Cobb angle, at the beginning and the end of the study, as well after twelve weeks as a follow up. SPSS was used for statistical analysis. Results: There were no significant differences at the baseline of the study (P-values > 0.5). Statistical analysis shown high significant differences (P-values < 0.005) at 7th week. There was high statistical significant in pain intensity (P-values < 0.005), and significant differences in neck disability (P-values < 0.05), while there were no significances for cervical kinematics measures (P-values > 0.05) at follow up. Only pain intensity showed significant differences (P-values < 0.05) in all groups and other outcome measures have no statistical significant differences (P-values > 0.05) at follow up. The study showed that both CL and LP have extended mild analgesic effect and gained moderate improvement of neck disability. Conclusion: It was concluded that CL and LP (632.8 nm, 24 J/cm2) per tender areas/ selected acupoints were recommended as a physical therapy modality in treating patients with PCLS.
