Subject has been receiving medication for persistent post-operative low back and/or radiating leg pain, including opioid or non-opioid analgesic medication, and is on a stable analgesic dosing regimen (i.e. the same medications and dosages) for > 30 days prior to the Screening Visit.
Average Pain Intensity (calculated as the mean of the daily Average Pain Intensity scores for either back and/or leg) is ≥ 3 and < 9 as measured on Numeric Pain Rating Scale (NPRS) during the 10-day run-in period.
Subject has completed a minimum of 80% (8 of 10 possible) of the electronic Patient Reported Outcome (ePRO) assessments during the 10 day run-in period.
Subject is able to access an internet browser in the home environment.
Subject is willing and able to give written informed consent and to comply with all parts of the study protocol.
Female subjects must be post-menopausal, surgically sterile, abstinent, or practicing (or agree to practice) an effective method of birth control if they are sexually active for the duration of the study.

Subject had disc fusion at any level in the most recent surgery.
Subject has received any investigational drug or device within 30 days or 5 half-lives of the drug, whichever is longer, prior to the Screening Visit or is enrolled in another clinical trial.
Subject has undergone any local injection into the lumbar spine within 30 days prior to the Screening Visit or within 6 weeks prior to the Screening Visit for long acting lidocaine injection products.
Subject has used systemic corticosteroids within 2 months of the Screening Visit.
Subject has a history of any uncontrolled medical illness that in the investigator's judgment places the subject at unacceptable risk for receipt of PEMF therapy.
Subject has a history of malignancy within the past five years other than successfully treated non-metastatic basal cell or squamous cell carcinomas of the skin in the treatment area and/or localized in situ carcinoma of the cervix.
Subject has an ongoing painful condition that in the opinion of the investigator might have a confounding influence on the safety or effectiveness analyses for this study.

Subject has an implanted pacemaker, defibrillator, neurostimulator, spinal cord stimulator, bone stimulator, cochlear implant, or other implanted device with an implanted metal lead(s).
Subject consumes an average of > 100 mg oral Morphine Sulfate equivalents per day during the 10 day run-in period.
Standard deviation around the mean of the average pain intensity scores during the 10 day run-in period is > 2.0.
Subject has a Body Mass Index (BMI) > 38 kg/m2.
Subject is currently pregnant or planning on becoming pregnant prior to Day 75.
Subject has been previously treated with the PROVANT Therapy System.
