Short-Term Response of Thoracic Spine Manipulation With or Without Trigger Point Dry Needling for Mechanical Neck Pain

Brooke Army Medical Center42 enrolled

Overview

This study will assess the short term response of thoracic spinal manipulation with or without trigger point dry needling in 58 subjects with a primary complaint of mechanical neck pain.

Neck pain is common, and return to duty rates after medical evacuation from theater for spinal pain is low. Muscles comprise the majority of the stability for the cervical spine, yet neck muscle function can be altered in the presence of pain. Research has consistently shown the benefit of including thoracic spine manipulation (SMT) in the treatment of patients with mechanical neck pain. Emerging evidence is now also showing promising benefit of including trigger point dry needling (TDN) for the treatment of mechanical neck pain. Treatment regimens commonly address anterior cervical stabilizing musculature, but little is known regarding the response to treatment of the deep posterior stabilizing musculature. This study will assess the short term response of thoracic SMT with or without TDN in 58 subjects with a primary complaint of mechanical neck pain. Subjects will be randomized to receive 2 treatment visits approximately 2-3 days apart of either SMT+sham TDN or SMT+TDN. TDN will be directed to the upper trapezius and deep cervical extensor muscles of the neck. Outcomes of interest will be changes in function and pain. Assessments will be made at baseline, immediately after the first treatment, at the 2nd treatment, and approximately 5-7 days after the 2nd treatment visit. A subgroup of 20 subjects (10 per group) will also have the upper trapezius and deep cervical extensor muscle activation assessed via shear wave elastography, and deep cervical flexor activation assessed via the craniocervical flexion test.

Interventions

Thoracic spinal manipulationPROCEDURE

All patients will receive 3 different thrust joint manipulations to the middle and upper thoracic spine region. Each technique will be applied up to 2 times, per the discretion of the treating therapist discretion

Trigger point dry needlingPROCEDURE

The TDN treatment will consist of a trained investigator inserting a needle through the participant's skin, into the deep cervical extensor muscles and/or the upper trapezius muscles using FDA approved (FDA regulation # 880.5580) disposable 0.2-0.3 x 40-50 mm stainless steel Seirin J-type needles (Seirin, Japan). Those subjects randomized to TDN will undergo this treatment.

Outcomes

Primary Outcomes

Change in Neck Disability Index (NDI)

The NDI is a revised form of the Oswestry Low Back Pain Index. It is designed to measure the activities of daily living in persons with neck pain.

Time frame: Change in NDI from baseline to 2-3 days

Change in Neck Disability Index (NDI)

The NDI is a revised form of the Oswestry Low Back Pain Index. It is designed to measure the activities of daily living in persons with neck pain.

Time frame: Change in NDI at 7-10 days

Secondary Outcomes

Change in Numeric Pain Rating Scale (NPRS)

An 11-point NPRS will be used to measure pain intensity. The scale is anchored on the left with the phrase "No Pain" and on the right with the phrase "Worst Imaginable Pain".

Time frame: Change in pain from baseline to 2-3 days

Change in Numeric Pain Rating Scale (NPRS)

An 11-point NPRS will be used to measure pain intensity. The scale is anchored on the left with the phrase "No Pain" and on the right with the phrase "Worst Imaginable Pain".

Time frame: 7-10 days

Global Rate of Change (GRC)

The GRC assesses subjective perception of overall change over time and the importance of that change. A 15-point Likert type scale ranging from -7 (very great deal worse) to +7 (a very great deal better) will be used.

Time frame: 2-3 days
