Ultrasound Physiotherapy
When an ultraswave propagates in human tissues, its energy is incessantly absorbed by tissues and changed into heat to elevate the temperature of tissue cells, so as to enhance blood circulation, accelerate metabolsm, enhance local histotrophic nutrition, and strengthen the activity of enzyme .
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 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.
The effect of therapeutic ultrasound via an increase in local blood flow may help reduce local swelling and
chronic inflammation, and, according to some studies,promote bone fracture healing. The intensity or power
density of the ultrasound can be adjusted depending onthe desired effect. A higher power density (measured in
watt/cm2) may soften or breakdown scar tissue.
*Bursitis
*Tendonitis
*Muscle Strain and tears
*Osteoarthritis
*Ligament and tendon injuries
* Soft tissue injuries.
* Chronic strains and sprains.
* Myositis – the inflammation of muscle tissues.
* Bursitis – inflammation of the fluid-field pads surrounding joints.
* Tendonitis – inflammation of the tissue connecting the muscles to the bones.
* Tendon Sheath Inflammation.
* Osteoarthritis.
* Plantar fasciitis.
Precautions in Ultrasound Treatment
Always use the lowest intensity which produces a therapeutic response
The head of the applicators should be moving throughout the treatment
The ultrasound beam (treatment head) should be perpendicular to the treatment area for best results.
All parameters (intensity, duration, and mode) need to be considered carefully for desired therapeutic effects.

Ultasound wave Principle:
1.Mechanical function: the ultrasound have the [micro massage" to the tissue substance and tiny cell. It could soften tissue, enhance penetration, improve metabolism, promote blood circulation, stimulate nerve system and cell, relief pain.
2.Heating function: it forms heat during ultrasound therapy, so it is also called
as"ultrasound diathermy therapy". it is deep heating, that penetrate below the muscle.
Thus, ultrasound therapy is applied to chronic soft tissue pain, arthritis, rheumatism.
3.Physical therapy function: based on the mechanical and heating function,
it will trigger physical therapy.
