On the whole, subjective (VAS score for pain, VAS score for patient's global assessment, VAS score for global health assessment) and objective (swollen and tender joint counts) variables, as well as US variables, significantly improved throughout the follow-up.
Partial correlation demonstrated that only PAG volume in CM was negatively related to the VAS score, which indicated the PAG volume changes may be associated with VAS score.
Average of VAS score was 8.48.
The mean VAS score for perceived usefulness was 59%.
The VAS score 0 10 measured the intensity of headache.
A mean VAS score of 76.2 ± 16.0 was found.
At follow-up, the mean VAS score was 2.5 (±2.5).
A good clinical outcome was defined as an increased ROM (ROM > 38 mm) and a decreased VAS score (VAS score < 20%, and <60% of the preoperative level).
The primary end point was the comparison of the VAS score at 1 month.
80% showed improvement in the VAS score and functional improvement in Prolo score.
Seventy-four (26.4 %) patients reported mild pain (VAS score 1 3), 165 (58.9 %) reported moderate pain (VAS score 4 6), and 41 (14.6 %) reported severe pain (VAS score 7 10).
