Detailed Description
Pain is a major problem due to issues such as the impact on quality of life and the associated health and social costs. Neck pain is a very common disorder in our society. It is characterized by the presence of hyperalgesia, increased muscle tone, limited range of motion and sensitization. It is well known that pain of visceral origin can generate all these phenomena. In most cases, there is no antecedent of trauma, and no evidence of a specific origin (oncologic, rheumatic, infectious…), so patients are classified as suffering non-specific or idiopathic pain. The absence of a specific diagnosis makes it difficult to find a therapeutic target to increase the probability of successful therapies. Thus, in the case of neck pain, the recurrence of consultations is very high.
It is known that cervical pain frequently presents peridiaphragmatic visceral comorbidities. Furthermore, it is known that these peridiaphragmatic organs produce referred pain to the neck, and this pain is known as phrenic pain. To date, there are no studies that analyze the role of phrenic afferents in subjects with neck pain and peridiaphragmatic visceral disorders. The aim of this study is to evaluate the effect of phrenic nerve anaesthesia in subjects with neck pain. For this purpose, the investigators intend to perform a randomised clinical trial, assessing the effects on pain threshold to pressure, visual analogue scale, range of motion and craniocervical questionnaires. There will be only one intervention session. The experimental group will receive an ultrasound-guided anaesthetic infiltration of the phrenic nerve, while the control group will receive a placebo infiltration. A one-week follow-up, with intermediate measurements, will be carried out to assess the evolution of cervical sensitization and symptomatology.
The results of this study will make it possible to establish the role of peridiaphragmatic organic disorders and phrenic afferents in cervical pain, thus making it possible to specify a specific therapeutic target (phrenic nerve) as well as the importance of visceral treatment in subjects presenting for consultation for cervical pain.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Phrenic nerve anesthetics infiltration
The experimental intervention will consist of ultrasound-guided anesthetic blockade of the phrenic nerve at the laterocervical supraclavicular level with 1 ml of lidocaine without vasoconstrictor 2% to infiltrate the skin and 3ml of bupivacaine without vasoconstrictor 0.25% for neural blockade, making the local anesthetic surround the nerve between the anterior scalene muscle and the sternocleidomastoid muscle.

Placebo Comparator: Physiological serum infiltration
The placebo intervention will be similar in relation to 2% lidocaine without vasoconstrictor for the skin, but an ultrasound-guided puncture will be performed at the level of the subcutaneous cellular tissue by injecting 3 ml of physiological saline.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline in algometry
Time Frame: Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 days and 7 days
|
Pressure pain threshold in neck tissues.
PPT levels defined as the minimum necessary pressure to evoke pain will be evaluated using a handheld electronic pressure algometer.
|
Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 days and 7 days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Range of motion
Time Frame: Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 days and 7 days
|
Neck range of motion.The range of motion will be assessed in degrees.
Flexion, extension, left and right side flexion, and left and right rotation will be assessed, and the sum of all of those parameters will be the considered outcome.
|
Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 days and 7 days
|
Visual Analogue Scale
Time Frame: Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 hours, 6 hours, 24 hours, 2 days, 3 days and 7 days
|
Perceived neck pain.
Self-perceived pain intensity will be evaluated during all active cervical movements by a 0 to 10 Visual Analogue Scale (VAS), where 0 denotes no pain and 10 denotes the maximum possible pain.
|
Pre-intervention. Post-intervention: 1 hour, 2 hours, 3 hours, 6 hours, 24 hours, 2 days, 3 days and 7 days
|
Neck Disability Index
Time Frame: Pre-intervention. Post-Intervention: 3 days and 7 days.
|
Neck Disability Index (Questionnaire).
The Neck Disability Index will be used in the Spanish version.
This questionnaire assesses how neck pain affects the ability to manage everyday-life activities.
Scores range from 0-50 with higher scores indicating higher disability.
|
Pre-intervention. Post-Intervention: 3 days and 7 days.
|
Headache Impact Test-6
Time Frame: Pre-intervention. Post-intervention: 3 days and 7 days.
|
Headache Impact Test (Questionnaire).
The Headache Impact Test-6 was developed to measure a wide spectrum of the factors contributing to the burden of headache, and it has demonstrated utility for generating quantitative and pertinent information on the impact of headache.
Scores range from 0-120 with higher scores indicating a worse outcome.
|
Pre-intervention. Post-intervention: 3 days and 7 days.
