How does the Ultrasound work?
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.
