Therapeutic Potential of Digital Nerve Block in Rheumatoid Arthritis Patients: A Clinical and Sonographic Prospective Study

This study attempted to test the effectiveness of digital nerve block (DNB) in active rheumatoid arthritis (RA) joints with respect to local disease control. Methods: The study included 83 RA patients aged 18 years or above and diagnosed, after American College of Rheumatology/European League Against Rheumatism criteria 2010, with bilateral proximal interphalangeal (PIP) arthritis. PIPs were examined by European League Against Rheumatism-outcome measures in rheumatoid arthritis clinical trials scoring system at 0, 2, and 8 weeks. Visual analog scales for each hand were also done at the same intervals. DNBs of the second and third PIPs were performed to the dominant hand in 50% of participants. The other hand was used as a control, and saline was injected in the same level at the control side. Results: At 2 weeks and 8 weeks intervals, the active side showed significantly less clinical and ultrasound scores when compared to the control side and the baseline values. The mean OMERACT score for the active hand dropped from 3.37±1.43 at 0 time to 2.31±1.66 after 2 weeks and 2.55±1.43 at 8 weeks (P
