The Immediate Effects of Dry Needling on Post-concussion Syndrome

Official title: The Immediate Effects of Dry Needling on Post-concussion Syndrome

Status Withdrawn

Clinical Trial Summary

In about 15% of adult concussion cases, symptoms last longer than 2 weeks and can largely impact the individual's ability to work, be physically active and participate in everyday life. These symptoms are often partially related to unresolved neck muscle tightness and other neck-related symptoms. Dry needling is a technique that uses acupuncture needles to release muscle knots, decrease neck muscle tightness and decrease neck pain. As far as the investigators are aware, there have been no studies looking at the effects of dry needling on symptoms of chronic concussion. This study will compare the effects of dry needling to traditional hands-on physiotherapy treatment of the neck for concussion-related symptoms. Participants with chronic concussion symptoms will receive either dry needling, hands-on manual physiotherapy or both. Concussion symptoms, symptom severity, neck range of motion and pain with pressure over neck muscles will be compared before and after treatment, and the day after treatment. The investigators expect that the greatest improvement in all of these will be seen in the group receiving both interventions, both immediately after treatment and the following day. If dry needling can immediately improve concussion symptoms, patients may better tolerate therapeutic exercise and experience quicker resolution of chronic symptoms.

Clinical Trial Description

All participants will be tested in clinic once, for approximately a half hour. For all groups, outcome measures relating to concussion symptoms, cervical range of motion and pain pressure thresholds will be taken prior to and after the intervention.

In the DN group, four muscles (upper fibres trapezius, cervical multifidus, levator scapulae and suboccipitals) will be palpated by a physiotherapist trained in dry needling. If a palpable trigger point is found, the physiotherapist will perform dry needling until a local twitch response is elicited. If a trigger point is not found, no dry needling will take place. In this way, up to 8 total muscles will be needled during the session. The participant will be in prone for the above procedure.

In the MT group, soft tissue release will be performed on the above four muscles bilaterally. Cervical traction (unilateral grade 3 oscillatory distraction technique, any cervical segment between C0/C1 and C7/C7, 3-5 sets of 30 seconds) and mobilization (unilateral inferior-medial-posterior or superior-anterior-lateral, grade 3 oscillatory, any cervical segment between C0/C1 and C7/C7, 3-5 sets of 30 seconds ) will also be performed if the physiotherapist deems it necessary, specific to the spinal level noted to be involved. In the DN+MT group, MT interventions will be performed first, followed by DN, of the four above muscles. Immediately following intervention, the outcome measures will all be re-tested. The participants will also be instructed to fill out the SCAT-5 Step 2 upon waking the next morning. Additionally, if one or more of the cervical motions caused pain during initial testing, they will be asked to repeat the motion and report the current level of pain on the VAS scale. ;
