Inclusion criteria

• Are you between 18 and 80 years of age (inclusive)?

• Are you willing to document usage of any medications during the study period?
• Do you agree to discontinue all other interventional treatment modalities on the lower back during the study? (e.g., transcutaneous electric nerve stimulation [TENS], electronic muscle stimulation, traditional ultrasound, massage therapy, chiropractic services)
• On a Numeric Rating Scale (NRS) of 0 (no pain) to 10 (pain as bad as you can imagine), how would you rate your average pain over the past week? Pain must be ≥4 for the subject to be enrolled in this study. This criterion will be assessed by self-report at Visit 1.
