The purpose of the study was to
Myofascial pain syndrome is a common musculoskeletal pain affecting 30% of patients in primary care. It is characterized by trigger points in the upper trapezius muscle, which is linked to neck and shoulder pain. Non-invasive treatments like exercises, manipulation, and physical agents have been suggested for managing neck pain. Laser therapy, including low-level and high-intensity, has been found effective in reducing pain intensity and improving functional activity. Instrument-assisted soft tissue mobilization is another technique used to treat Myofascial pain syndrome. Instrument-assisted soft tissue mobilization stimulates connective tissue remodeling, resorbing excessive fibrosis, and promoting collagen repair and regeneration. The study aims to investigate the effect of high intensity laser therapy versus Instrument-assisted soft tissue mobilization in treating Myofascial pain syndrome of the upper trapezius muscle.

| High Intensity Laser | Device | The therapeutic dose of laser therapy depends on power density, tissue color, and type. Darker skin may absorb the laser in the epidermal layer, but HILT can pass through without absorption. Research has improved power density and dose, with the World Association of Laser Therapy recommending a 5-7 J/cm2 dose for optimal therapeutic outcomes. |
| Measure | Description | Time Frame |
|---|---|---|
| Assessment of change of pain intensity | The Visual Analog Scale is a self-reported pain measurement scale with a 10-cm line labeling extreme pain levels. It is valid, reliable, and suitable for clinical practice, especially for individuals over 18. Studies have shown moderate to strong correlations for VAS validity in pain measurement. | At baseline and after 1 month |
| Measure | Description | Time Frame |
|---|---|---|
| Assessment of change of pressure pain threshold | A pressure algometer is a reliable tool for determining local pressure pain threshold (PPT) in different pain syndromes. It is a force gauge calibrated in kg/cm2 and has a range of 0-10 kg/cm2. A manual pressure algometer will be used to measure pain threshold for upper trapezius fibers, with repeated measurements to improve reliability. | At baseline and after 1 month |

| Instrument-assisted Soft Tissue Mobilization | Other | Instrument-assisted soft tissue mobilization is a popular alternative to traditional manual therapy techniques, derived from Cyriax cross-friction massage. It uses hard tools to manipulate soft tissue, varying in direction, force, and pattern, and allowing pressure to disperse to underlying tissues. Modern Instrument-assisted soft tissue mobilization instruments vary in material and design, and are used to improve musculoskeletal conditions and outcomes. Patients receive Instrument-assisted soft tissue mobilization with an M2T blade, positioned at a 45° angle, and instructed to apply an ice pack if experiencing burning sensations. |
|
| Conventional treatment | Other | conventional physical therapy, which includes ultrasound, isometric neck exercises, chin tucks, stretching of neck muscles, and neck stabilization exercises, were used for groups A, B and C |
|
| Assessment of change of Cervical range of motion | The CROM device is a lightweight, comfortable, and secure device that adjusts to a patient's head, resembling eyeglasses. It features two independent inclinometers, one in the sagittal and one in the frontal plane, and a third in the horizontal plane, indicating head rotation. The device is easy to use, requires minimal palpation, and is affordable compared to more advanced motion analysis systems. | At baseline and after 1 month |
| Assessment of impact of neck pain on quality of life | The Neck Bournemouth Questionnaire (NBQ) is a tool measuring neck pain's impact on daily activities and emotional well-being. It covers seven areas and scores 0 to 70, with higher scores indicating greater disability. The NBQ is sensitive and validated in English, French, Dutch, and Arabic. | At baseline and after 1 month |
