The aim of this study is to evaluate the effects of vibration anesthesia for reducing pain induced by trigger point injection of gastrocnemius. Sixty patients were randomized into the vibration or placebo group. In vibration groups, vibrator head was applied (100Hz) on the popliteal fossa, during the trigger point injection. In placebo group, same vibrator head was applied with switch-off sate. Then, a visual analog scale to evaluate the pain of trigger point injection and a five-point Likert scale for patients satisfaction were compared between the two groups.

Visual analog scale
100 mm visual analog scale for evaluating the pain of trigger point injection
Time frame: Immediately after trigger point injection (within 5 minute)
5 point Likert scale for participant satisfaction
5 point Likert scale to answer "Are you satisfied with the vibration application for reducing the pain of trigger point injection?"
Time frame: Immediately after trigger point injection (within 5 minute)
5 point Likert scale for repeated usage
5 point Likert scale to answer "Will you use the vibration application again if the trigger point injection is repeated in the future?"
Time frame: Immediately after trigger point injection (within 5 minute)
