 The above named study only assessed immediate pain-related changes due to the intervention and did not assess functional improvements. The investigators of this study were not able to find any articles investigating this phenomenon in the lower extremity. This project will use a similar set up as the above study, but the subjects will receive sham DN, not real DN in a non-trigger point tissue which, as explained above, will still elicit physiological effects and could have some segmental influence as in the above named study. In addition, the investigators will explore if there are functional improvements in subjects receiving DN. Consequently, the investigators propose to perform the following controlled study that explores the questions Does site specific trigger point dry needling evoke segmental neuromodulation in the lower extremity and if so, do these changes make an impact on the subjects disability?.
