简要总结
The goal of this interventional study is to test the effects of trigger point dry needling to the low back in a healthy population. The main aims are to answer:
- Is there a change in sensitivity to experimental pain after trigger point dry needling
- To determine if there is an association between demographic and psychological factors and immediate changes in pain sensitivity after receiving trigger point dry needling.
Participants will be randomly assigned to one of two groups a dry needling group or a sham dry needling group. The dry needling group will receive trigger point dry needling to the lumbar spine. The sham dry needling group will receive needling to the lumbar spine with a sham needle which does not penetrate the skin.
In other words, researchers will compare an intervention group and a sham group to see if dry needling has an immediate change in pain sensitivity in response to experimentally induced pain.
详细描述
The intent of this study is to investigate the effects of trigger point dry needling on pain sensitivity in a healthy population. In this study, the effects of trigger point dry needling will be measured using quantitative sensory testing. This is a method of testing pain sensitivity by providing a painful stimulus and having the participant rate their response to the stimulus on a pain scale. In this way, the researchers will be able to determine changes to participant's response to painful stimuli and changes to the nervous system after trigger point dry needling interventions to the low back. This information will provide important insight as to how dry needling modulates pain.

结局指标
主要结局
Change in Cold Thermal Pain Threshold degrees Celsius baseline and Cold Thermal Pain Threshold degrees Celsius immediately following intervention
时间窗: Baseline and immediately following the intervention
Participants will indicate when an thermode of descending temperatures first changes from a sensation of cold to painful by saying "pain" and indicating the amount of pain with a visual analog scale. This change will be calculated by taking the difference between the two scores.
Change in Pressure Pain Threshold Kilopascals baseline and Pressure Pain Threshold Kilopascals immediately after following intervention
时间窗: Baseline and immediately following the intervention
Participants will indicate when ascending pressure from an algometer first changes from a sensation of pressure to painful by saying "pain" and indicating the amount of pain with a visual analog scale. This change will be calculated by taking the difference between the two scores.
Change in baseline Conditioned pain modulation
时间窗: Baseline and immediately following the intervention
Pressure pain threshold will be assessed immediately prior to and following a pain inducing cold water bath immersion. Condition pain modulation will be defined by the changes in pressure pain threshold prior to and immediately following the cold water bath immersion
Change in Heat Thermal Pain Threshold degrees Celsius baseline and Heat Thermal Pain Threshold degrees Celsius immediately following intervention
时间窗: Baseline and immediately following the intervention
Participants will indicate when an thermode of ascending temperatures first changes from a sensation of warmth to painful by saying "pain" and indicating the amount of pain with a visual analog scale. This change will be calculated by taking the difference between the two scores.
Change in baseline After sensation
时间窗: Baseline and immediately following the intervention
After sensation is the term used to describe the measurement of pain that remains after a painful stimulus. Participants will rate the pain remaining every 15 seconds for a total of one minute following the final thermal pulse in the Thermal Temporal Summation protocol (as described in outcomes 4). The numeric rating scale is (0 - 100) with "0" being no pain at all and "100" being worst pain imaginable
Change in baseline Thermal Temporal Summation
时间窗: Baseline and immediately following the intervention
Participants will rate the pain associated with a series of 10 heat pulses applied to the skin on a 0 to 100 numerical rating scale with 0= no pain to 100= worst pain imaginable.
