Tissue Changes in Lumbar Multifidus After Dry Needling in Subjects With Nonspecific Low Back Pain.

20. november 2021 oppdatert av: Sebastián Rodríguez PosadaSebastián Rodríguez Posada, University of Alcala

Association Between Tissue Changes in Lumbar Multifidae and Improvement in Pain and Disability After Dry Needling in Subjects With Nonspecific Low Back Pain. Randomized Clinical Trial.

Finding out if tissue changes (thickness, histogram and shrinkage rate) that occur in the lumbar multifidus after deep dry needling are related to changes in patient's pain and disability.

Detaljert beskrivelse

Lower back pain in regarded as the main cause of disability in the world, which has a significant socio-economic impact. Deep dry needling is effective in handling such pain and is one of the techniques of choice by physiotherapists. In this area, the use of ultrasound provides information of interest such as length, thickness, diameter, cross-sectional area or muscle volume, among others.

Objective: Finding out if tissue changes (thickness, histogram and shrinkage rate) that occur in the lumbar multifidus after deep dry needling are related to changes in patient's pain and disability.

It's a double-blind randomized clinical trial in parallel groups. Patients will be randomly divided into 2 groups. One of them will receive dry needling and the other dry needling placebo. The initial, post-needling and a week after evaluations will be performed by a blinded to the intervention therapist.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Placebo komparator: Control group
Placebo dry needling
Annen: Placebo dry needling
Placebo dry needling will be performed with DongBang DB100 Acupuncture Needles which, upon contact with the patient, retract, hiding in the needle handle. The patient will be in the prone position with a pillow in the abdominal region. The area will be cleaned with an antiseptic and allowed to air dry for 3 minutes. At the point indicated by the evaluator, the placebo needle will be placed initially and the introduction of the needle and its location will be simulated with the ultrasound system. 10 repetitions will be performed. The needle will be removed by depositing it in a needle container and a compression will be made in the treated area.
Eksperimentell: Experimental group
Dry needling
Annen: Dry needling
The dry needling will be performed using disposable stainless steel needles (AGU-PUNT needles of size 0.30x50mm or 0.30x60mm depending on the patient) that will be inserted perpendicularly at the point of major hyperalgesia using the Hong technique. The patient will be in the prone position with a pillow placed in the abdominal region. The area will be cleaned with an antiseptic and allowed to air dry for 3 minutes. After this time, the needle will be inserted at the point indicated by the evaluator before reaching the lumbar multifidus by means of echolocation. Once it is assured that it is in the right place, a total of 10 repetitions are performed. The needle will be removed by depositing it in a needle container and a compression will be removed in the treated area until hemostasis is achieved.

Hva måler studien?

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Changes from baseline in pain on the 10-point Visual Analog Scale (VAS, 0-10 score) at immediatelypost-needling and a week after.
Tidsramme: Baseline, immediately post-needling and a week after.
This scale shows concurrent and predictive validity in the assessment of pain. A difference of 2 points represents a clinically significant change that exceeds the limits of measurement error.
Baseline, immediately post-needling and a week after.
