The purpose of the current study will be focused on the following issues. Evaluation of the effect of magnetic therapy on sonographic findings ,the pressure pain threshold and disability in stroke hemiplegic shoulder.

Further understanding of rotator cuff tendon impairment and other shoulder soft tissue structural abnormalities in stroke patients may help clinicians in assigning more complete therapeutic plans to hemiplegic patients. The radial extra-corporeal shock-wave therapy has promising results in patients with musculoskeletal problems and in those with various causes of HSP, including spasticity, rotator cuff problems, adhesive capsulitis, and complex regional pain syndrome.

Inclusion Criteria:

1. Patient's age was between 40 to 50 years old with
2. mild spasticity (grade 1, +1) according to modified Ashworth scale (MAS)
3. All conducted patients experienced a single stroke more than six months with cognitive capacity that enables them to comprehend and follow the instructions (Mini-Mental Scale score > 24).

Exclusion Criteria:

• history of shoulder pain, trauma, or surgery before the stroke; current treatment with warfarin and an international normalized ratio greater than 4.0; use of oral non steroidal anti inflammatory drugs within 3 days before enrolment; or intra articular injections within the previous month. Patients who were unable to report their pain intensity, those with a cardiac pacemaker, and those with clinically significant osteoporosis were also excluded

The patients in control group will be treated by sham radial extracorporeal shock wave therapy in addition to, the same design physical therapy program. Stimulation will not deliver as the transmitter head will be removed.

The patients will receive the same frequency of air pressure and
