Diclofenac Phonophoresis Versus High Power Pain Threshold Ultrasound on Patients With Neck Pain

Diclofenac Phonophoresis Versus High Power Pain Threshold Ultrasound in Patients With Mechanical Non-specific Neck Pain

the aim of this study is to investigate the effect of diclofenac phonophoresis versus high power pain threshold ultrasound in patients with mechanical non-specific neck pain

Neck pain can be a long-lasting condition, Between half and three quarters of patients with neck pain will experience recurrence within 1-5 years. Costs for the society due to neck pain are consequently high. Neck pain (NP) is one of the common musculoskeletal problems. NP can be caused by the stress over the musculoskeletal system due to postural disorders and may also be associated with other causes such as intervertebral disc herniation, nerve compression, or fracture. Musculoskeletal pain due to trigger points is one of the most prevalent reasons for patients to seek treatment. The aim of physical therapy treatment in patient with myofascial pain syndrome is to reduce the pain and restore normal function. Most physical therapy treatments for MPS are targeted to the deactivation of MTrPs. Physical therapy techniques include manual therapies; such as ischemic compression, spray and stretch, strain and counter strain, muscle energy techniques, trigger point pressure release, transverse friction massage; needling therapies, and other techniques such as thermotherapy, ultrasound therapy , phonophoresis and laser therapy.Due to the semi-solid properties, a special method is needed for transdermal permeation of lidocaine. Therefore, many studies have focused on enhancing the level of transdermal permeation by either changing the physiochemical properties of lidocaine or using physical modalities In particular, there has been considerable interest in transdermal permeation using various methods based on the idea that the amount and depth of transdermal permeation can be increased using various physical modalities. patients with mechanical neck pain will be allocated randomly into three equal groups; group A will receive phonophoresis and traditional therapy, group B will receive high power pain thresholdand traditional therapy and group C will receive traditional therapy
