Lying Positions in Intramuscular Injection (Lying)

May 19, 2026 updated by: Handan Eren, University of Yalova

The Effect of Three Different Lying Positions on Pain, Comfort, and Satisfaction Levels in Intramuscular Injection: A Randomized Controlled Trial

The aim of this study is to examine the effects of intramuscular (IM) injections administered in three different lying positions (supine, prone, and lateral) into the ventrogluteal site on patient pain, comfort, and procedural satisfaction. The study will be conducted as a randomized controlled experimental trial with three groups. In Experimental Group 1, patients will be placed in the supine position; in Experimental Group 2, the lateral position; and in Experimental Group 3, the prone position prior to the injection procedure, followed by an IM injection into the ventrogluteal site. Subsequent to the procedure, patients' pain, comfort, and procedural satisfaction levels will be assessed.
