Investigating the Minimum Number of Needling Required to Optimize Trigger Point Injections Outcome

Myofascial pain is a common condition in which patients may experience severe chronic pain. The source of this pain is typically the soft tissue. Current methods to address myofascial pain include a procedure called Trigger point Injections. This method involves identifying the areas of muscles that are causing the pain. The most common way to perform trigger point injection involves infiltrating the muscle with local anesthetics and then repeatedly passing the numbing needle in and out of the muscles (needling). This procedure is successful for most patients. However, there is great variability in the way needling is done. Some pain physicians perform 1-2 needle passes while other pain physicians may exceed 20 passes. There are currently no guidelines as to the number or amount of needle passes needed to achieve pain control. Furthermore, there is no study or research to shed light on the relationship between the number of needles passes and the degree and duration of pain relief coupled with patients' satisfaction. This study is proposed to address this gap in knowledge. It is a prospective and randomized clinical trial that follows the standard of care. The investigators will recruit patients from The University-Banner Medical Center at Tucson, Arizona chronic pain clinic who are candidates for trigger point injections. The participants will be randomized into 3 different groups. Group one will receive 2 needle passes per identified trigger point. Group two will receive ten needle passes per identified trigger point. Group three will receive twenty needle passes per identified trigger point. The investigators will analyze the data to understand the relationship between the number of needles passes and the degree of pain relief, improved functional capacity, and patients' satisfaction.

The Effectiveness of Dry Needling Treatment in Patients Diagnosed With Dorsal Myofascial Pain Syndrome.

Back pain is commonly seen in the working-age population, with the peak occurrence around the age of 40. Its frequency does not increase with age and is not associated with age-related degenerative changes in the spine. Especially when the underlying cause is conditions such as myofascial pain syndrome (MPS), where regional muscle sensitivity in the rhomboid and trapezius areas is prominent, dry needling treatment has become increasingly popular and the subject of numerous studies in recent years. In the diagnosis of MPS, two valuable findings include the detection of a taut band upon palpation and the presence of trigger points in muscle fibers with mild finger pressure. The study we are planning involves a double-blind efficacy trial where real and sham dry needling procedures will be performed under ultrasound guidance, ensuring that both the patient and the evaluator are blinded. This study design has the potential to make a significant contribution to the literature in this field.

The Therapeutic Effects of Dextrose Injection for Myofascial Pain Syndrome

Patients with an myofascial trigger point (MTrP) in their upper trapezius will be divided into three groups: Group A receiving MTrP injection with normal saline (control group), Group B with hypo-osmolar dextrose (5% dextrose), and Group C with hyper-osmolar dextrose (15% dextrose). Clinical outcomes and morphological changes will be measured before the injection, one hour after, one week after, two weeks after, and one month after the injection to delineate the therapeutic effects of dextrose injection for an MTrP.

Myofascial Release Technique in Women With Primary Dysmenorrhea

It has been found that women with dysmenorrhea have active trigger points, particularly in the rectus abdominis, oblique abdominal muscles, quadratus lumborum, and paraspinal muscles. The myofascial release technique is a widely used manual therapy method characterized by the application of low-load, long-duration mechanical forces to manipulate the myofascial complex. This technique aims to restore optimal length, alleviate pain, and improve function. This study aims to examine the effect of the myofascial release technique on central sensitization, myofascial trigger points, and menstrual symptoms in women with primary dysmenorrhea.
