Subacromial Corticosteroid Injection for Hemiplegic Shoulder Pain

- A total of 105 chronic stroke survivors with moderate to severe shoulder pain will be
enrolled. Subjects will be enrolled in the study for 13 weeks. Subjects who complete the
protocol will visit MetroHealth five times.

- Visit 1: Baseline information about demographics, past medical history, and
inclusion/exclusion issues will be collected for study participants. Pertinent lab work
will be performed to determine initial eligibility.

- Visit 2: All initially eligible participants also will undergo a test injection of
lidocaine to localize the pain to the subacromial bursa (Neer's Test). A positive Neer's
test is required to finalize eligibility for further participation. Participants who
satisfy inclusion/exclusion criteria (including a positive Neer's test) will be
randomized to high dose steroid, standard dose steroid, or low dose steroid via a
computer generated random number table. The study participants and the observer will be
blinded as to these groupings.

- After the initial Neer's test and randomization, participants will receive their
assigned injection the same day. Participants then will be followed for an additional 12
weeks, including three follow-up visits (Visits 3-5). The total participation time in
this study will be 13 weeks.

- The primary outcome measure will be the BPI 12. The BPI is a pain questionnaire, which
assesses the "worst pain" in the previous 7 days. Secondary outcome measures also will
be assessed together with BPI 12. There will be 3 additional secondary outcome measures,
Fugl-Meyer Motor Assessment (a measure of poststroke motor impairment), pain free
external rotation range of motion (ROM) and pain free abduction ROM.

- A blinded therapist will administer all outcome measures. The primary outcome will be
assessed on a weekly basis via telephone (or in person during weeks of MetroHealth
visits) starting on the day of Visit 1 and continuing to 12-weeks after steroid
injection (i.e., for the 13 weeks of the subject's participation). The remaining
secondary outcomes will be assessed in clinic visits at least every 4 weeks starting
with Visit 2 (Visits 2-5).

Inclusion Criteria:

- Age greater than 18

- upper extremity hemiplegia due to hemorrhagic or nonhemorrhagic stroke

- ≤ 4/5 on manual muscle testing for the deltoid on the affected side if isolated
movement is present

- post-stroke duration ≥ 1-mo, but < 24-mo

- shoulder pain sustained for ≥ 1-mo

- BPI 12 ≥ 4 (pain scale)

- willing and able to report pain and other conditions throughout the 4-mo study period

- positive Neer's test

Exclusion Criteria:

- evidence of joint or overlying skin infection

- > 2 opioid and/or nonopioid analgesic for shoulder pain (i.e., > 2 regardless of
class)

- regular intake of pain medications for any other chronic pain

- steroid injections to the shoulder in the last 6-wks

3/3 registration and recall the same three objects in 30 minutes. The participant must
also be able to correctly rank the following three levels of pain from highest to
lowest: 1) falling from a 2-story building and breaking both ankles, 2) stubbing one's
toe and 3) getting bitten by a mosquito.

- immunocompromised
