Effect of Skin Stretching on Pain Reduction During Local Anesthetic Injections: A Randomized Clinical Study

The purpose of this study is to investigate the potential analgesic effect of skin stretching during local anesthetic injection in patients with chronic lumbar pain and bilateral lower extremity radiculopathy undergoing selective transforaminal nerve block. This research is based on the hypothesis that mechanical skin stretching can reduce injection-related pain by facilitating the dispersion of the anesthetic agent and decreasing tissue resistance. By comparing the skin stretching technique with the conventional method of local anesthetic administration, this study aims to evaluate differences in pain perception, discomfort, and behavioral pain responses. The ultimate goal is to provide evidence for a simple, non-invasive, and effective intervention that can improve patient comfort and enhance the quality of clinical pain management.
