Objective:
To evaluate whether exposure to different metronome rhythms is associated with variations in patient-reported pain intensity and anxiety levels during transperineal prostate biopsy performed under local anesthesia.
Methods:
This single-center, prospective, non-randomized study included 200 patients undergoing TPBx. Patients were assigned according to routine clinical workflow to a control group or metronome rhythm groups at 60, 80, 100, or 120 bpm. Pain was assessed using the Visual Analog Scale, and anxiety was evaluated using the State-Trait Anxiety Inventory. The primary outcome was overall procedural pain.
Results:
Final analysis included 196 patients. Overall pain scores and pain during local anesthetic administration differed significantly among groups (P <.001). The lowest pain scores were observed in the 100 bpm group. Post-procedural anxiety scores were significantly lower in the 60-100 bpm groups compared with the control and 120 bpm groups. Baseline characteristics were comparable.
Conclusion:
Metronome rhythm-based auditory stimulation was associated with differences in pain and anxiety during TPBx and may represent a simple adjunct to improve patient experience.

The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
