Comparative Clinical Trial: Manual Therapy With and Without Radial Extracorporeal Shockwave Therapy to Treat Acute Low Back Pain

The goal of this clinical trial is to learn if the addition of radial pulse therapy to chiropractic care will help adult patients recover faster to an acute bout of low back pain. Radial pulse therapy is the application of acoustic waves that passes through the skin to tissues and cells in the body. The main questions that the clinical trial aims to answer are: * Does the addition of radial pulse therapy to chiropractic care result in better or earlier reduction in pain intensity? * Does the addition of radial pulse therapy to chiropractic care result in better or earlier improvement in physical function? Researchers will compare radial pulse therapy plus chiropractic care to chiropractic care alone to see if patients with acute low back pain recover faster with the addition of radial pulse therapy. Participants will: * Visit the clinic once a week for 5 weeks * Receive chiropractic care with or without the addition of radial pulse therapy to the low back and hip regions of the body * Report their pain intensity and perform a physical function test at each clinic visit
