Brief Summary

This study will be conducted to investigate the difference between high-intensity laser and extracorporeal shock wave on supraspinatus tendon thickness, subacromial space, occupation ratio, shoulder pain intensity, shoulder range of motion (ROM), hand strength, and functional disability in patients with chronic supraspinatus tendinopathy.

Conditions

Supraspinatus Tendinopathy

Keywords

High-intensity Laser Therapy; Extracorporeal Shock Wave; Tendon Thickness; Chronic Supraspinatus Tendinopathy

Outcome Measures

Primary Outcomes (3)

• supraspinatous tendon thickness

  supraspinatus tendon thickness will be assess by ultrasonography.The tendon often appears swollen or thickened (frequently \> 6 to 7 mm)

  up to 6 weeks

• supracromial space

  supracromial space will be measured by ultrasonography. A normal resting subacromial space generally ranges from 9 to 11 mm. A measurement of less than 6 mm is often pathological

  up to 6 weeks

• occupation ratio of subacromial space

  The ratio comparing the thickness of the supraspinatus tendon to the overall acromiohumeral distance. An increased occupation ratio (i.e., a thickened tendon taking up too much of the space) indicates a higher risk of impingement

  up to 6 weeks

Secondary Outcomes (4)

• pain intensity

  up to 6 weeks

• shoulder range of motion

  up to six weeks

• upper limb disability

  up to six weeks

• supraspinatus muscle strength

  up to six weeks

Study Arms (3)

High-intensity Laser Therapy

EXPERIMENTAL

ACTIVE COMPARATOR

Twenty-three patients with chronic supraspinatus tendinopathy will receive conventional physiotherapy twice a week for six weeks

Other: conventional therapy

Interventions

High-intensity Laser Therapy OTHER

the patients will receive HILT with peak power 3kW, intensity 15000W/cm and energy per pulse 350 mj) at supraspinatus tendenopathy.The treatment consisted of 3 phases in each session. the initial phase will be rapid manual scanning (100 cm2/30s) of the anterior joint line of the shoulder with one shot of 850 mj at frequency of 30 Hz. The scanning will be performed parallel to the joint line, with the patient arm internally rotated on the posterior scan and externally rotated on the anterior scan. the intermediate phase will be a fixed scan phase , with one -shot emission of 350mj at a frequency of 20-25Hz. plus conventional therapy

High-intensity Laser Therapy

Extracorporeal Shock Wave OTHER

patients will be sitting with shoulder abduction at 45 and elbow flexed and the forearm rested on flat surface and shock wave applicator directed in the most tender point near the insertion at the greater tubrosity under acromion with 2000 impulses, and energy flex density of 0.22mj/mm , pulse rate 10/sec and frequency 1-15 Hz plus conventional therapy

Extracorporeal Shock Wave

conventional therapy OTHER

will receive Conventional physical therapy in form of stretching exercise of posterior shoulder capsule, passive stretching exercise, will be done only 3 times with holding time 30 sec and 10 sec rest period between repetitions , strengthing exercise consists of 3 exercises all have been recommended as essential for any shoulder rehabilitation program. These exercise include shoulder flexion, scaption and horizontal extension. for each exercise, a 10-repetition maximum for 3 sets with 60 sec rest between every set + TENS and hot back.
