Summary

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.

Conditions

• Lumbar Spinal Stenosis With Bilateral Lower Extremity Radiculopathy

Interventions

Type	Name	Description
PROCEDURE	conventional local anesthetic injection	A conventional infiltration anesthesia will be conducted on the lumbar area of the patient, targeting the epidermis and subcutaneous tissue. A 25G syringe will be used, with the needle angle set between 30° and 45°. 1cc of 1% lidocaine will be injected. The target size of the wheal is 5-10 mm.
PROCEDURE	skin stetching technique for local anesthetic injection	Skin stretching techinique will be applied to the local anesthetic injection site by stretching the skin around the needle entry point.
