Efficacy of Intramuscular Electrical Dry Needling and Dry Needling over Quadratus Lumborum Muscle Among Mechanical Low Back Pain Subjects - a Pilot Study

Mechanical Low back pain is represented by pain or discomfort in the lower back area, frequently coupled with a reduced in flexion to the sides. According to the prevalence from the global burden of disease study done in 2023, eighty-nine percent of people suffered among sedentary populations. This research is designed to determine the effect of Intramuscular Electrical Dry Needling (IMEDN) stimulation and Dry Needling (DN) in the management of pain pressure threshold (PPt), Postural sway (PS) among patients with mechanical LBP. In this study, Thiry-four individuals who satisfied the research criteria aged 30 to 45 years were divided into two groups. Group A underwent treatment with Intramuscular electrical dry Needling Stimulation, while Group B was treated with Dry Needling. Before and after the three-week treatment duration, the outcome measures PPt and PS were assessed using pressure algometry and lords sway meter. The calculated p value for variables PS and PPt were 0.021 and 0.012 which less than the common alpha level (α=0.05). There was substantial variation in PPt and PS was observed between IMEDN and DN. Both the dry needling technique and the intramuscular dry needling stimulation approach would help patients with mechanical low back pain minimize their PPt and PS, according to the statistical results. Intramuscular Dry Needling Stimulation is superior to Dry Needling in terms of controlling pain pressure threshold and postural sway in people with mechanical low back pain, despite the fact that all the variables that were measured showed comparable improvements for both treatment groups.
