The Effect of Dry Needling of the Gluteus Medius Muscle in Patients With Chronic Low Back Pain

University of Haifa25 enrolled

Overview

The effectiveness of dry needling of the Gluteus Medius muscle in combination with active exercises will be examined compared with sham needling with active exercises in low back pain (LBP) patients.

Objectives: To examine if dry needling in combination with active physiotherapy is more effective in reducing pain and increase activity of daily living, range of motion and muscle strength in patients with chronic low back pain compared to sham dry needling in combination with active physiotherapy. Methods: the study will include individuals with non-specific LBP over 3 months. Subjects will be divided randomly into two research groups, both will receive physiotherapy including mobility, strengthening and stretching exercises. Intervention group, additionally to exercises, will receive dry needling to the Gluteus Medius muscle by inserting a needle to a trigger point until a visible involuntary twitch in the muscle appears. Sham needling will be applied by needling with pre-cut and smoothed needles that will not penetrate the skin. Both groups will receive two treatments per week and up to six treatments overall, evaluation will be performed before and after the series of treatments.

Outcomes

Primary Outcomes

change in visual analog scale (VAS)

assessing pain on a scale from 0 (no pain) to 10 (most sever pain). Higher scores means worse outcome.

Time frame: baseline and at 3 weeks

Change in Modified Oswestry Disability Index

questionnaire to assess the disability level associated with LBP and includes 10 questions regarding activities likely to be affected by LBP. Higher scores means worse outcome.

Time frame: baseline and at 3 weeks

Global rating of change

a 15-point Likert scale ranging to assess treatment success. Higher scores mean a better outcome.

Time frame: 3 weeks

Secondary Outcomes

Change in hip abductors muscle strength

muscle strength in Newton, assessed by an hand held dynamometer

Time frame: baseline and 3 weeks

Change in lumbar flexion range of motion

lumbar flexion assessment by bending forward and measuring distance of fingers from the floor

Time frame: baseline and 3 weeks
