Ultrasound-guided vs. Blinded Dry Needling for Piriformis Syndrome

Not Applicable
Not yet recruiting
Conditions
Piriformis Syndrome
Interventions
Procedure: Ultrasound-guided dry needling
Procedure: Blinded dry needling
Registration Number
NCT05882799
Lead Sponsor
Uskudar State Hospital
Brief Summary

This randomized controlled trial aims to compare the effectiveness of ultrasound-guided versus blinded dry needling for the treatment of piriformis syndrome.

Detailed Description

This randomized controlled trial aims to compare the efficacy of ultrasound-guided versus blinded dry needling for the treatment of piriformis syndrome. Patients in both groups will receive three weekly sessions of dry needling performed by a single experienced physiatrist. The intervention will involve inserting a sterile acupuncture needle into the trigger points of the piriformis muscle and manipulating the needle to elicit a twitch response. Patients in the ultrasound-guided group will receive dry needling under real-time ultrasound guidance, while patients in the blinded group will receive dry needling without ultrasound guidance. Patients will be assessed before treatment, after treatment, after the third week, and after three months.

Primary Outcome Measures
NameTimeMethod
Change in Visual Analog Scale for PainFirst day, after three weeks, after three months

A Visual Analog Scale (VAS) for pain is a commonly used tool to measure the intensity of pain experienced by a patient. It typically consists of a horizontal or vertical line, typically 10 centimeters long, with endpoints labeled as "no pain" and "worst possible pain." The patient is asked to mark on the line the point that best represents the intensity of their pain, with the distance from the "no pain" end of the line to the patient's mark representing the pain score.

Change in Oswestry Disability Index (ODI)First day, after three weeks, after three months

The Oswestry Disability Index (ODI) is a self-administered questionnaire that is widely used to assess the functional status of patients with low back pain or sciatica. The ODI consists of 10 sections, each relating to a different aspect of functional impairment, such as pain intensity, personal care, lifting, walking, sitting, standing, sleeping, social life, traveling, and employment/homemaking. Each section is scored on a scale of 0-5, with a total score ranging from 0 (no disability) to 50 (complete disability). The ODI is a validated and reliable tool for assessing functional status and has been used in many clinical trials to evaluate the effectiveness of interventions for low back pain or sciatica.
