High Level Pulsed Heat
Subjects randomized to this arm received a generation 5 device (Soovu Labs Inc.) that produced 30 minutes of heat. The heat was delivered as waves peaking at 45° C. Generation 5 device Soovu Labs Inc.: The Soovu Labs Inc. battery powered device is a one inch diameter heating pod that attaches to the user via a ring system. The device may be programmed to deliver a wide variety of treatment algorithms. Control of the devices are through a phone-based bluetooth connection. The treatment algorithm used for all subjects in this arm pulsed heat to a temperature of 45 degrees C.
Low Level Steady Heat
Subjects randomized to this arm received an identical device (Soovu Labs Inc.) that produced 30 minutes ot heat. The heat was delivered in a steady manner at 37° C. Generation 5 device Soovu Labs Inc.: The Soovu Labs Inc. battery powered device is a one inch diameter heating pod that attaches to the user via a ring system. The device may be programmed to deliver a wide variety of treatment algorithms. Control of the devices are through a phone-based bluetooth connection. The treatment algorithm used for all subjects in this arm maintained a steady temperature of 37 degrees C.

OTHER_PRE_SPECIFIED outcome

Timeframe: Changes in the Numerical Pain Scale will be compared between baseline and thirty minutes post intervention.

Population: All subjects with longstanding chronic low back pain median duration 10 years. Subjects who received the high level pulsed heat device with heat pulses up to 45 degrees C. Steady heat subjects received a device that heated to 37 degrees C at a steady level.

Numerical Pain Scale Range Zero (minimum) through ten (maximum score) In this study a lower number on the Numeric Pain Scale means the subject(s) has less pain. Less pain particularly in the experimental group is a better outcome.
