Here is a marketing hype link explaining BFST.
Anyone have an opinion on electro-magnetic approach?
Just some general info below. First, my thoughts on the device-mostly hype and unnecessary as very deep heat not needed. A physical therapy modality popular several years ago used ultrasound. I actually have one of the devices. However, some studies raised the possibility of deeper tissue oxidation (cooking the muscle) over time which may have been a reason for almost nonuse now. You may find this useful to put things in perspective:
Ultrasound
Ultrasound is a deep heating modality that is most effective in heating tissues of deep joints. It has been found to be helpful in improving the distensibility of connective tissue, which facilitates stretching. It is not indicated in acute inflammatory conditions where it may serve to exacerbate the inflammatory response and typically provides only short-term benefit when used in isolation. It is perhaps best used to improve limitations in segmental spinal range of motion following recurrent or chronic low back pain as an adjunct in facilitating soft tissue mobilization and prolonged stretching by a skilled manual therapist.
The use of ultrasound is contraindicated over a previous laminectomy or peripheral nerve secondary to alterations in membrane stability. It should be discontinued as segmental motion is improved with the patient then moved into an active strengthening program and eventual transference to an independent home exercise program.
Superficial Heat
Superficial heat can produce heating effects at a depth limited to 1-2cm. Deeper tissues are generally not heated due to the thermal insulation of subcutaneous fat and the increased cutaneous blood flow which dissipates heat. It has been found to be helpful in diminishing pain and decreasing local muscle spasm. Superficial heat, such as the hydrocolater pack, should be used as an adjunct to facilitate an active exercise program. It is most often used during the acute phases of treatment when the reduction of pain and inflammation are the primary goals. If beneficial, it can be incorporated into the education program and utilized on a home basis prior to the therapy program.
