SI Joint Pain Clinical Trial
Official title:
VaReFi Validity and Reliability of Diagnostic Findings of SI Joint Blocking
The purpose of the trial is to confirm the validity and reliability of diagnostic SI joint blocks.
Subjects with suspected SI joint pain will undergo 3 SI joint blocks, 2 with local anesthetic
and 1 sham block.
The sequence of blocks is randomly assigned. This study examines both the test-retest
reliability of response to diagnostic sacroiliac (SI) joint injection and the specificity of
response to local anesthetic or sham block. The goal of the study is to validate the use of
diagnostic SI joint block.
Subjects with pain suspected to be generated by one SI joint will undergo three diagnostic SI
joint blocks each separated by one week. Two blocks will be with local anesthetic (LA) and
one will be a sham block (SB). Both the Coordinator (collecting pain assessments) and subject
will be blinded to the sequence of blocks (LA or SB each time). The sequence of blocks will
be randomly assigned for each subject on study. The subject's participation in the study is
complete after 6-month post-procedure assessment.
