Figure 2: Percent Improvement in Post-Traumatic Stress Disorder (PTSD) After Treatment with Stellate Ganglion Block (SGB)
aCases 1, 2, & 12-24 scores measured using the PTSD Checklist - Military Version (PCL-M), cases 3-11 scores measured using Clinician Administered PTSD Scale (CAPS).
bFor case 19, change measured using scores from pre-SGB 1 and post-SGB 3 due to limited data;
c Overall=Improvements in PTSD calculated as the difference in either PCL-M or CAPS scores from pre-SGB 1 to post-SGB 2 or 3. PTSD improvement as measured by the PCL-M were adjusted by subtracting 17 from all pre- and post-SGB scores given the baseline value of PCL-M starts at 17, not 0 as is the case for CAPS.
