Brief summary
The purpose of this study will investigate the effect of adding high power pain threshold ultrasound to traditional therapy on axioappendicular muscles amplitude and fatigue in neck pain
Detailed description
Myofascial pain syndrome is a common musculoskeletal pain disorder affecting almost 95% of people with chronic pain disorders and is a common finding in especially pain management centres.It is characterized by trigger points, defined as hyperirritable spots within taut bands of skeletal muscle fibers. The syndrome is associated with tenderness in the muscle, referred pain, spasm and restriction of motion. Patients with MPS begin with one active MTrP (called the primary MTrP) in the affected muscles due to chronic repetitive minor muscle strain, poor posture, systemic diseases, or neuro-musculoskeletal lesions. When not treated correctly, expansion of the pain region and additional active MTrPs (called secondary or satellite MTrPs) will develop one of the most appropriate treatments for trigger points ultrasound therapy. The high-power pain threshold ultrasound (HPPTUS) technique is one of the ultrasound modifications used to treat trigger points In 2004, Majlesi et al. performed the first clinical study to compare this technique with the traditional ultrasound technique in patients with myofascial trigger points. The results showed that HPPTUS was much more effective than the traditional technique, and pain reduction and improved range of motion (ROM) were significant in a smaller number of sessions.sixty patients with mechanical neck pain will be assigned randomly to two equal group. one group will receive high power pain threshold ultrasound and traditional therapy and the other receive traditional therapy alone for four weeks. .
Interventions
After explaining the procedure, and the trigger points will be marked by a physical therapist that . Then, the hand placed next to the prone position with the head in the neutral position, and the hands placed next to the body. The frequency was set to 1 MHz, and the intensity increased from 0.5 to 2 until the patient reported an unpleasant sensation. The probe will be held there for 4 s; then, the intensity was reduced by 50%, and the probe was moved over and around the trigger point. This process is done several times for three minutes.
OTHERtraditional therapy
the patients will receive traditional therapy in the form of postural correction exercise, active range of motion and stretching exercise for cervical muscles
