 If the patient is deemed eligible for the study, the investigating PT will explain the study to the prospective subject and heshe will be asked if heshe wants to participate. The PT will explain that the subject might not get the actual DN technique, but instead a sham. If the subject declines heshe will receive treatment as normal. If heshe agrees, heshe will receive the informed consent to read and sign. If there are study-related questions they will be answered. After this the subject will fill out an intake sheet for demographic information, the modified Oswestry Disability Questionnaire mOSW Copay as well as a pain map and visual analog scale VAS for low back pain. The subject will then determine hisher group allocation by drawing a piece of paper out of an opaque envelope. This envelope will contain 40 pieces of paper; 20 of them will specify dry needling A for treatment, 20 will specify dry needling B for sham.
