Dry Needling

Low back pain is one of the most common health issues worldwide, and in most cases, this pain is nonspecific low back pain (NSLBP). NSLBP is characterized by the inability to determine the real source of the pain and commonly presents with myofascial trigger points (MTrPs) in the muscles related to the lumbar region. One of the most widely used techniques for treating NSLBP by targeting MTrPs is dry needling (DN), a technique that involves inserting a needle to produce a mechanical effect capable of "deactivating" the MTrP and thereby alleviating its symptoms. However, some studies have concluded that other techniques are more effective than DN, such as percutaneous electrolysis (PE). When using the PE technique, it appears that adding a galvanic current enhances the effects of DN. Nonetheless, this poses a greater risk to the patient, as the galvanic current could damage nervous tissue if it comes into contact. For this reason, it is proposed to investigate whether other physical agents that are not electrical could enhance the effect of DN without increasing its risk. This is the case for vibration, a stimulus that has already been used successfully for the treatment of MTrPs, allowing us to investigate whether adding vibration to DN introduces therapeutic capabilities that: * Maintain or increase the effectiveness of DN in terms of pain and functional capacity. * Do not add risks for the patient, unlike PE. * Are less painful than DN and cause less post-needling pain than that generated after successive needle insertions with DN. Emphasizing these adverse effects is necessary since most clinical trials do not report these variables, which is fundamental for describing the safety of invasive techniques. Following this idea, the present project will analyze a new invasive therapy for the treatment of MTrPs: dry needling with vibratory stimulus (DN+V), for which the following hypotheses are proposed: * DN+V, instead of using an electrical stimulus like PE that could cause damage to some tissues, will apply vibration to the DN needles to increase the mechanical stimulus exerted on the MTrP, expecting greater benefits in terms of pain, functional capacity, muscle strength, and other variables of interest in individuals with NSLBP, and possibly requiring less treatment time than DN. * In DN, the repeated insertions and withdrawals of the needle in the MTrP provoke a hemorrhagic and inflammatory reaction that translates into hypersensitivity and microscopic tissue injury in the muscle, causing pain during treatment and post-needling pain for the following 24-32 hours. Another study showed that PE caused less post-needling pain than DN, which may be due to the fact that, unlike DN, it is common in PE to only perform a single puncture with each needle and not mobilize them. * The methodology for DN+V will be the same as for PE, with a single puncture and no needle manipulation, so it is expected that DN+V, being less invasive than DN, will reduce pain during treatment and post-needling pain compared to that generated by DN. There are studies that support this hypothesis, concluding that needle manipulation in DN produces greater post-needling pain than DN without needle manipulation.

Dry needling is a skilled intervention provided by trained physical therapists to treat pain, myofascial dysfunction, and a variety of other diagnosis. While there is research demonstrating the benefits of dry needling in reduction of pain and improvement in strength, research in regards the pediatric population is very limited. I recently completed a retrospective chart review regarding dry needling trends and outcomes in the pediatric orthopedic population. We now know the pediatric population is tolerating this treatment and seeing benefits. Physical therapists are already pushing the boundaries and finding additional benefits in the use of dry needling with our current patients. A diagnosis frequently seen in sports medicine is surgical reconstruction of the anterior cruciate ligament (ACL). Over the last couple of years, therapists have seen an increase in the use of quadriceps tendon autograft for reconstruction following ACL tears due to lower incidence rate of retears. These patients have been struggling to regain strength of the quadriceps to meet desired outcomes. The quadricep muscles are one of the major stabilizers of the knee and with a reduction in strength places the patient at a significant increase of retear. Subjects will be categorized into an experimental group (dry needling intervention + physical therapy) or the control group (physical therapy only) with a N of 20 in each group. The goal for this research is to determine if dry needling use in the subacute phase of post-operative ACLR following quadriceps autograft can assist with increasing quad strength and improve post-surgical outcomes.

The goal of this clinical trial is to learn if the addition of cadaver review improves: * the accuracy of physiotherapists who practice dry needling. * the perceived safety of dry needling by physiotherapists. Researchers will compare the effects of an anatomy review using cadaver material to that of an educational intervention not related to anatomy to see if the anatomy review improves the needling accuracy and safety of physiotherapist who practice dry needling as compared to the control intervention of education not related to anatomy. Participants will: * Needle three muscles related to safety and/or accuracy using ultrasound imaging to gather accuracy and safety measurements. * Take an initial knowledge exam capturing their knowledge on needling safety. * Be randomized into a control group or intervention group. * The control group will receive an online educational session not related to anatomy. * The intervention group will receive a cadaver anatomy review class focused on high-risk area. * Re-take a knowledge exam after their course (either cadaver lab or on-line education) to capture any change. * Needle the same three muscles again using ultrasound to capture accuracy and safety measurements. If reviewing anatomy using cadaver materials improve physiotherapists needling accuracy and safety, then this educational intervention could be recommended to be added to dry needling course instruction.

This study aims to compare the added effects of dry needling and dry cupping to conventional physical therapy on headache pain intensity, headache frequency, headache duration, upper cervical range of motion, and disability levels in patients with cervicogenic headache. It will be assumed that: * All patients will follow all the given instructions strictly during the study duration, regarding the assessment and the treatment procedure. * All participants will be evaluated under the same environmental conditions.
