About this study

Patients will be randomized into either Cervical High-Intensity Resistive Exercises group or Conventional physical therapy group. Patients will receive the intervention for six weeks. Outcomes will be assessed at baseline and post-intervention.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Thirty-four patients diagnosed CNSNP.
  • Age of the patients between 20-40 years.
  • Non-specific neck pain started more than 3 months.
  • Reduce ventilatory function; FVC >= 70% from predicted.
  • Waist to height ratio (WtHR)> 60 %.
  • Positive craniocervical flexion test.
  • Positive neck flexor endurance test.
  • Pain at neck after prolonged static weight bearing positions.
  • Pain with palpation of the neck paraspinal or suboccipital or trapezius muscles.

Exclusion criteria

  • History of whiplash injury.
  • Clinical sign of cervical radiculopathy.
  • Clinical signs of cervical myelopathy.
  • Rheumatoid Arthritis or any other autoimmune diseases.
  • Any respiratory disorders.
  • Tumors.
  • vertebrobasilar insufficiency VBI.

Treatment and study plan

Cervical High-Intensity Resistive Exercises

Other

The patient will wear a neck harness, and a weight equivalent to 90% of the patient's measured maximum voluntary isometric contraction (MVIC) will be attached to it.

Conventional physical therapy

Other

Conventional physical therapy consisting of TENS for pain control, soft tissue release for the cervical and associated muscles, activation and strengthening exercises for the deep neck flexors, extensors, and scapular muscles, as well as diaphragmatic breathing exercises.
