About

shoulder sub acromial impingement syndrome is an encroachment of subacrormial tissues, rotator cuff, subacrormial bursa, and the long head of the biceps tendon, as a result of narrowing of the subacrormial space. Activities requiring repetitive or sustained use of the arms over head often predispose the rotator cuff tendon to injury. Hence the objective of the study is to examine the influence of extra corporeal Shock wave versus phonophoresis on pain severity and functional disability in patients with sub acromial impingement syndrome.

Full description

Background: shoulder sub acromial impingement syndrome is an encroachment of subacrormial tissues, rotator cuff, subacrormial bursa, and the long head of the biceps tendon, as a result of narrowing of the subacrormial space. Activities requiring repetitive or sustained use of the arms over head often predispose the rotator cuff tendon to injury. Objective of the study: To examine the influence of extra corporeal Shock wave versus phonophoresis on pain severity and functional disability in patients with sub acromial impingement syndrome. Subjects and Methods: Thirty patients diagnosed as shoulder impingement syndrome stage II Neer classification due to mechanical causes. Patients were randomly distributed into two equal groups. The first group consisted of 15 patients with a mean age of 45.46 (+ 8.64) received therapeutic exercises( stretching exercise of posterior shoulder capsule and strengthening exercises of shoulder muscles) and shockwave therapy (6000 shock, 2000/session, 3 sessions, 2 weeks a part, 0.22mJ/mm2) years. The second group consisted of 15 patients with a mean age of 46.26 (+ 8.05) received same therapeutic exercises and phonophoresis (3 times per week, each other day, for 4 consecutive weeks). Patients were evaluated pretreatment and post treatment for shoulder pain severity, shoulder functional disability, shoulder flexion, abduction and internal rotation motions.

Enrollment: 30 patients

Sex: All

Ages: 30 to 50 years old

Volunteers: No Healthy Volunteers

30 participants in 2 patient groups

Shockwave therapy

Experimental group

Description:

All patients were received (ESWT) at sitting position, exposed the affected shoulder, the shoulder adducted and elbow extended and the shock wave applicator was directed in most tender point near the insertion of rotator cuff at greater tuberosity under the acromion \[23\]. The treatment area was prepared with a coupling gel to minimize the loss of shockwave at the interface between applicator tip and skin. Each patient was received (6000 shocks,21000 shock/ session, 3 session 2 weeks apart, energy flux density 0.22 mJ/mm2, energy level 5-7, pulse rate 160/min., 2-3Hz)

Treatment:

Device: Shockwave therapy

Phonophoresis

Description:

Pagani ultrasound apparatus 200 cosistts of multi frequency head(1 and 3 MHz), surface area 4 cm², continuous and pulsed mode, main voltages: 100-240-VAC.50/60Hz.

Treatment:

Device: Phonophoresis
