"A Randomized Double-Blind Placebo-Controlled Trial of Botulinum Toxin Type A (BOTOX ) in the Treatment of Hemiplegic Shoulder Pain and Spasticity"
The purpose of this study is to evaluate whether botulinum toxin type A injected into muscles
around the shoulder is effective in treating shoulder pain and improving function in patients
with shoulder pain and involuntary muscle tightness after a stroke.
around the shoulder is effective in treating shoulder pain and improving function in patients
with shoulder pain and involuntary muscle tightness after a stroke.
Subjects with shoulder pain and spasticity at the shoulder following a stroke resulting in
hemiplegia are eligible for participation. Following an initial screening visit involving a
history and physical examination, subjects will be entered in to the study if they have
significant spasticity of shoulder internal rotation/adduction associated with pain rated at
least a 4 on the VAS for pain. Subjects will also be given a cognitive screening in which
they will be asked to rate pain in hypothetical situations.
Shoulder pain is a frequent complication following hemiplegic stroke, and may result in
further disability. Spasticity is also a complication following stroke . Botulinum toxin is
used in the treatment of post-stroke spasticity and may also have pain modulating effects.
Participants in this study will be asked to make total of 6 visits over a period of
approximately 13 weeks. Eligible subjects will be randomized to 100 to 200 units of botulinum
toxin type injected into the pectoralis major at the second visit. If there is significant
spasticity for shoulder extension, subjects will also receive injections into the teres
major. Subjects will be followed up with assessments of pain, functioning, active and passive
range of motion and depression following the initial injection. At the 12 weeks post
injection visit, the blinding will be broken and subjects initially injected with placebo
will be injected with the active drug. This will be done to give all subjects an opportunity
to receive the active drug, as well as to assess the effects of any differences with delayed
treatment. All subjects will return 4 weeks later to repeat the same assessments above.
Subjects will be called at one year post study enrollment for repeat pain ratings and for
information regarding subsequent treatments.
