Dry Needling Effectiveness and Post-punction Pain

Benefits and Harms of Dry Needling vs Transcutaneous Nerve Stimulation and Dry Needling in Patients With Chronic Myofascial Neck Pain and Relationship With Psychological Influences

The purpose of this estudy was to dertermine if the application of Transcutaneous Nerve Stimiulation (TENS) current have an hypoalgesic effect on pattientes suffering from miofascial neck pain, compared with a only dry needling treatment. Psicological varaibles were also mesured in order to determine how they change after each treatment.

Study Overview

• Status: Completed
• Conditions: Neck Pain
• Intervention / Treatment: Procedure: Transcutaneous Nerve Stimulation.; Procedure: Placebo needling; Procedure: Dry needling

Detailed Description

All patients suffered from mechanical neck pain and were randomized into three groups of treatment. A doible blinded control was carryed out. The main outcome messures were Visual Analogue Scale (VAS). The scondary outcome messures were Pressure Pain hreshold (PPT) and Active Range of Movement (ROM). Also psicologicla messures were taken, like Neck Dissability Index, Level of stress and ansiety, Fear Pain and Pain Avoidance Strategies.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: dry needling and TENS; A dry needling treatment was performed on trapezius trigger point number 2, and just after thar, a TENS curretn was applied. Patients will be reassed on fourth day after treatment.	Procedure: Transcutaneous Nerve Stimulation.; Transcutaneous Nerve Stimulation (TENS) is a current used for pain treatment. The needle will be used as the negative pole and a adhesive patch 2 centimeters lateral will be the positive pole. The frecuency selected will have 2 Hz with pulses of 120 microseconds. The currente will be applied for 15 minutes.
Placebo Comparator: Placebo; A placebo dry needling was performed on trapezius trigger point number 2. Patients will be reassed on fourth day after treatment.	Procedure: Placebo needling; No active technique is performed with the placebo needling. Patient will be supine and a placebo needle willb be performed. The patient will remain supine for 15 minutes.
Experimental: dry needling; A dry needling treatment was performed on trapezius trigger point number 2. Patients will be reassed on fourth day after treatment.	Procedure: Dry needling; Dry needlin is a manual therapy technique used for miofascuial pain syndrom treatment. The patient will be supine, in a confortable position. The therapist localizes the trapezius trigger point number 2 and then performes the needling until 2 REL are obtenined. The patient will remain supine during 15 minutes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual Analogue Scale	Visual Analogue Scale (VAS) is a subjective evaluation. There are previous studies that demonstrate its reliability and its sensitivity, wich give validity to VAS messures. The messure is made using a two sides 10 centimeters scale. The patient´s face shows an increasing slope that allows the patient to mark his pain level. That mark has his equivalent number on the scale, so 0 is no pain and 10 is maximum pain. A differece of 2 points on the scale means the minimum clinically significant change.	Patients will be reassed in four days.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Active Cervical Range of Movement	To messure the cervical range of movement, a CROM will be used. The CROM is a special goniometer that allows therapists to messure cervical movements. It conists on trhee pairs of inclinometers that allow reserchers to messure range of flexion-extension, lateral flexion and rotation. The CROM has a porved reliability, providing a inter-meter reliability from 0,7 to 0,9 and an intra-meter reliability from 0,8 to 0,87. The patient will be seated on a cheir, and he´ll perform cervical movements actively, just untill he starts to feel his pain. Each movement will be messure three times, and the average will be taken.	Patient will be reassed in four days.
Pressure Pain Threshold	Pressure Pain Threshold (PPT) is the minimun pressure needed to araise pain. To messure PPT, an digital algometer will be used. An algometer consists on a 1 square centimeter rubber piece inserted on a pressure gauge. Previous studies have shown the reliability of this method (ICC=0,91) and also inter meter (ICC from 0,82 to 0,97) and intra meter (ICC=0,78). The minimun detectable change on the cervical area goes from 0,44 Kg/cm2 to 1,11 Kg/cm2. We will apply the algometer over trapezius trigger point number 2, and the patient will tell the therapist when he start to feel hgis pain. We´ll do the messure 3 times and the average will be taken.	Patients will be reassed in four days.
