AbstractThis study aimed to investigate how the presence of neuropathic pain related to partial rotator cuff tears affects the short-term results of subacromial injection and suprascapular nerve blockade therapy in patients with chronic shoulder pain. In this prospective observational study, shoulder pain via verbal numeric pain rating (VNPR, 0-10) and functional status through simple shoulder test (SST) were evaluated before and second week after procedure. After dividing as neuropathic pain and non-neuropathic pain groups, pre-procedural and follow-up scores concerning pain intensity, functional status, and whether there were those of patients with minimal clinically important change (MCIC) in areas of pain and function were evaluated. Between the groups including 140 patients, while there was no statistical difference in baseline pain intensity and functional status (P = .14,.11, respectively), outcomes of those without neuropathic pain were favored at the follow-up (P = .02,.01, respectively). Given baseline pain scores, the reduction (%) was significantly lower in neuropathic pain group (P = .03). There was no significant difference in patients with MCIC in pain intensity and functional status between the groups (P = .08,.59, respectively). An improvement was determined in pain intensity and functional status at the follow-up in both groups (P < .001). The improvement in pain intensity and functional status is poorer in patients with partial rotator cuff rupture-related neuropathic pain than in those without neuropathic pain. However neuropathic pain has no negative effect on the response to treatment.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
