The Patient Expectation in Dry Needling and Analgesia
The Influence of Patient Expectation in Dry Needling Induced Analgesia
調査の概要

詳細な説明
Just before DN intervention, participants will receive a positive or a neutral expectation instructional set regarding effects of a DN technique on pain perception. This instructional set will be randomly allocated to each patient.
Participants in the positive expectation group will be told that DN procedure: "is a very effective form of treatment used to treat neck-shoulder pain and it is expected to reduce your perception of pressure pain". Participants in the neutral expectation group will be told that DN procedure: "is a form of treatment used to treat neck-shoulder pain that has unknown effects on your perception of pressure pain".
DN intervention An experienced and trained physical therapist will provide DN to all the subjects. This researcher will be blinded to the specific expectation instructional set the participant receives. Participants will receive one session of DN treatment for the active Myofascial Trigger Points(MTrP) located at the upper trapezius muscle. They will be placed in a prone position on the examination table. Solid filament needles of 0.30 mm diameter and 40 mm length will be used. The needle will be inserted into the skin over the palpated MTrP using pincer palpation, and slowly advanced perpendicularly until it reaches the MTrP and a twitch response is elicited.

Pain Intensity: Visual Analog Scale (VAS)
時間枠：Change from Baseline at after intervention
|
The investigators use a Visual Analog Scale (VAS) to determine the intensity of the patient's current pain before, during DN and immediately after DN.
We will follow the paradigm of Conditioned pain modulation (CPM) paradigm.
CPM will be induced by inflating an occlusion cuff (conditioning stimulus) at the arm, at the opposite side from the affected upper trapezius.The VAS is a 100-mm line, oriented horizontally, with one end representing "no pain"(the best value) and the other end representing "worst pain" (the worse value).
Subjects will be asked to rate their current pain with a mark on the scale.

Pain Pressure Threshold (PPT)
時間枠：Change up 1 hour
|
The PPT serves to determine the sensitivity of hiperalgesic focus. The investigators will done it with one algometer. Lower values are a worse result. Higher values are a better result. |

Dry needling pain
時間枠：Change up 1 hour

The investigators use a Visual Analog Scale (VAS) to determine the intensity of the patient's pain during DN intervention.The VAS is a 100-mm line, oriented horizontally, with one end representing "no pain" (the best value) and the other end representing "worst pain" (the worse value).
Subjects will be asked to rate their current dry needling pain with a mark on the scale.

Dry needling anxiety
時間枠：Change up 1 hour

The investigators use a Visual Analog Scale (VAS) to determine the anxiety of the patient during DN.The VAS is a 100-mm line, oriented horizontally, with one end representing "no anxiety"(the best value) and the other end representing "worst anxiety"(the worse value).
