Vibration for Pain Reduction During Trigger Point Injection

Not Applicable

Completed

• Conditions: Myofascial Pain Syndromes
• Interventions: Device: Vibration; Device: Placebo vibration

• Registration Number: NCT03365674
• Lead Sponsor: The Catholic University of Korea

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Vibration group	Vibration	Vibrator head was applied (100Hz) on the popliteal fossa, during the trigger point injection
Placebo group	Placebo vibration	In placebo group, vibrator head was applied with switch-off sate, during the trigger point injection

Primary Outcome Measures

Name	Time	Method
Visual analog scale	Immediately after trigger point injection (within 5 minute)	100 mm visual analog scale for evaluating the pain of trigger point injection

Secondary Outcome Measures

Name	Time	Method
5 point Likert scale for participant satisfaction	Immediately after trigger point injection (within 5 minute)	5 point Likert scale to answer "Are you satisfied with the vibration application for reducing the pain of trigger point injection?"
5 point Likert scale for repeated usage	Immediately after trigger point injection (within 5 minute)	5 point Likert scale to answer "Will you use the vibration application again if the trigger point injection is repeated in the future?"
