Primary

MeasureTime frameDescription
Number of participants with a reported Adverse Event7 daysCharacterize the number of adverse events for the combined use of RF and EMS with the BACK4 device across the device's intended configurations

Secondary

MeasureTime frameDescription
Number of participants with a device-related adverse event7 daysCharacterize the number of device-related adverse events for the combined use of RF and EMS in terms of with the BACK4 device across the device's intended configurations
Number of patients reporting therapy tolerability7 daysTherapy tolerability assessment will be ascertained by the subject using a 5-point scale (1=very uncomfortable, 2=somewhat uncomfortable, 3=neutral, 4=somewhat comfortable, 5=very comfortable)
