Effect of Dose Variations of High-Power Laser Therapy on Patients With Nonspecific Cervical Pain

Nonspecific neck pain, defined as pain without a specific underlying pathology, is a common musculoskeletal disorder that affects a significant proportion of the global population. Neck pain often results in considerable discomfort and functional limitations, impacting individuals' quality of life and ability to perform daily tasks. Estimates suggest that up to 30% of adults experience neck pain annually. The condition ranks among the top causes of disability worldwide, contributing to substantial personal and societal burdens, including lost work productivity and increased healthcare costs.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • unilateral or bilateral CNP
  • Experiencing moderate to severe neck pain, defined as a Visual Analog
  • Scale (VAS) score of ≥4.
  • Cervical Range of Motion (ROM) Limitation: Documented restriction in cervical ROM compared to normal values for age and gender, to ensure the condition's impact on functional mobility
  • Patients agreed not to take any medication(anti-inflammatories, analgesics, or muscle relaxants) throughout the course of the study or receive any type of treatment for neck pain

Exclusion criteria

  • Previous Cervical Surgery: Patients with a history of cervical spine surgery will be excluded to eliminate potential influences from post-surgical changes on the outcomes
  • Diagnosed with cervical disc prolapse as confirmed by clinical evaluation and imaging studies (MRI or CT scans).
  • History of malignancy in the cervical region or other serious medical conditions.
  • Severe comorbidities that may affect treatment outcomes (e.g., uncontrolled diabetes, cardiovascular diseases).
  • Pregnancy or lactation.
