About this study
In this study assessing whether platelet rich plasma injections(PRP) are effective in the management hemiplegic shoulder pain, 55 patients with hemiplegic shoulder pain was recruited to this randomized controlled study. Patients were randomized into two groups, first getting PRP injections, and other group taking sham injections.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PRPOther
Also called Platelet rich plasma injections
A venous blood sample of 8.5 ml were obtained from patients. For the study group, the blood samples were mixed with 1.5 ml ACD-A or sodium citrate to achieve anticoagulation. Resulting material was then centrifugated for 5 minutes with RCF 1200 G speed to clump erythrocytes, and then centrifugated for 10 minutes in same speed to obtain thrombocyte concentrate. 2 ml's of the platelet rich plasma was injected to the shoulder of the subjects. For the sham injection group, same amount of blood was taken and they were given a of waiting time of same duration with the study group, with the resulting preparate being 2 ml's of 0,9% saline instead. PRP solutions were prepared with kits of Easy PRP(Neotec Biotechnology, Istanbul, Turkey).
Injections were done every two weeks, for a total of 3 times. 21 G injection needles with injection technique of posterior approach were used(18, 19). To provide blindness, all injections were done using injectors coated with non transparent tape.
ExerciseOther
Also called Rehabilitation
All of the patients were also informed about proper positioning and the standard care for the affected extremity. Their process of neurological rehabilitation was not changed, which was 5 days of the week, one session of 45 minutes a day. They were also given a program of standardized ROM exercises, which included passive and active motions.

What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analogous Scale
Visual Analogous Scales for pain were used as outcome measures. Both resting and activity pain levels were evaluated. Patients were asked to describe their pain, level of disability or treatment satisfaction on a 10 cm long line, with 0 point being "none", and 10 cm point being "highest possible". The proximity of the marked point to the 0 end was measured, and the results were recorded
Measured: 3 months
Secondary outcomes (2)
Shoulder ranges of motion
Shoulder range of motions were also evaluated as outcome measures. The measurements were done accordingly to the guidelines of American College of Orthopedic Surgeons by a conventional goniometer(20, 21). The researcher who performed the measurements was an experienced in this field, and was blinded to the treatment groups. External and internal rotation, adduction, abduction, flexion and extension of both shoulders were recorded for each group.
Measured: 3 months
Functional Independence Measure(FIM)
Functional Independence Measure(FIM) is used to evaluate independence for the activities of daily living. It was developed to measure the results of the rehabilitation on the patient, and Turkish version of the tool shown to be valid and reliable in 2001. Having motor and cognitive subscales, the higher scores in FIM are interpreted as better functional independence.
Measured: 3 months
