Influence of Adding High Power Pain Threshold Ultrasound to Traditional Therapy on Axioappendicular Muscles Amplitude and Fatigue in Mechanical Neck Pain Randomized Clinical Trials
Condition: Neck Pain
MeSH terms: Neck Pain
Study type: Interventional

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.

Intervention name(s): high power pain threshold ultrasound; traditional therapy
Intervention type(s): Other; Other
Intervention description(s): 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.; the patients will receive traditional therapy in the form of postural correction exercise, active range of motion and stretching exercise for cervical muscles
