Stellate ganglion block for post-stroke complex regional pain syndrome

The Effect of Ultrasound-Guided Stellate Ganglion Block on Pain, Functionality, and Quality of Life in Type 1 Complex Regional Pain Syndrome in Stroke Patients

NA · Ankara City Hospital Bilkent · NCT07129811

This will test whether adding a stellate ganglion block to regular physical therapy reduces pain and improves arm function in adults with post-stroke complex regional pain syndrome.

What this trial studies

This interventional study will enroll 32 adults with post-stroke CRPS of the upper limb and a pain score greater than 4 on the VAS. Participants will be assigned to two groups: one receiving conventional physical therapy and exercise (10 sessions) plus stellate ganglion blockade, and the other receiving the same physical therapy without the block. Outcomes focus on pain intensity and functional use of the affected arm, measured before and after the treatment course. Common exclusion criteria include other neurological diseases, active infection, malignancy, open wounds at the injection site, and cognitive impairment.

Who should consider this trial

Good fit: Adults aged 18–75 with post-stroke CRPS (IASP 2012 criteria) and a VAS pain score above 4 who can attend in-person treatment in Ankara are ideal candidates.

Not a fit: Patients with other active neurological diseases, uncontrolled infection, malignancy, open wounds at the injection area, or significant cognitive impairment are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the approach could reduce pain and improve arm function during post-stroke rehabilitation.

How similar studies have performed: Small studies and case series have reported pain relief from stellate ganglion blockade for CRPS, but combining the block with conventional physical therapy specifically in post-stroke CRPS is novel and not well studied.
