Ultrasound Treatment for Pain
The human ear has a capacity of hearing sound between the frequencies of 40 Hz to 20 kHz (20,000 cycles per second). Ultrasound is at frequencies well above this, the therapeutic frequency being in the region of 1 to 3 MHz.
Effects of Ultrasonic Waves:
The conduction velocity of a nerve is reduced if is insonated with a dosage of 1 to 2 W / cm2 of ultrasonic energy. Micro massage effect with pulsed ultrasound will block pain pathways by lowering the nerve conduction velocity. If the cause of the pain causing depolymerisation of the mucopolysaccharides , mucoproteins, or glycoproteins, with increase elasticity and thereby reduced adhesions.
Ultrasound is also able to later the distribution of ion concentration at the pain receptor sites, and thus cause increased diffusion of the pain producing plasma peptides and H+ ion concentrations and thus remove the cause of pain.
Local rise of temperature – accelerates healing
- Extensibility of collagen increased
- Stretching of scar or adhesion
- Reduction of pain
One of the most recent treatment modalities available to physiotherapists is the Laser. Laser is an acronym formed the words “Light Amplification by Simulated Emission of Radiation”. Treatment units may combine helium – neon laser which produces a red light beam at 630 nm with an infrared at 904 nm. The useful depth of penetration with an infrared laser could be up to 30 mm, which is considerable deeper than the infrared from a conventional lamp.
Laser are claimed to have several physiological effects that promote healing and pain relief. There are many theories concerning the therapeutic membrane protein structural changes, ATPase activity change, resulting change in membrane ion pumps, and activation of enzymes like phospholipase.
It also is shown to have the following effects:
Promotes the synthesis of collagen and growth hormone.
Activates cells promoting healing like keratinocytes, or endothelial cell.
Generates new blood vessels (angiogenesis).
Lymphatic drainage is improved.
Traction is defined as the act of exerting a pulling force. It involves the application of both manual and mechanical force to adjacent body away from other each other. The resulting separation can decompress irritated tissues, realign parts, and relax tight structures. It helps in straightening fractured bones or relieving pressure on the vertebral column. In orthopaedics it is applied as skin traction, but in physiotherapy, cervical and lumbar traction are commonly applied.

How Stuff Works "Spinal Traction"
Cognitive Behavioral Method
Traction can help:
To lessen or eliminate muscle spasms and thereby pain.
To prevent or reduce skeletal deformities.
To reduce muscle contractures in early stages.
To regain normal alignment, especially in fractured.
Traction on the spine applies a longitudinal force to the spinal column, pulling it in opposite directions in order to stabilize or correct damaged parts of the spine. It is often given to release pressure on nerve roots, or herniated discs. It is being recognized as a very good stabilizer for cervical spines when they are injured or dislocated. Continuous traction; a light weight is applied for prolonged, spinal of time to achieve spinal stabilization in cervical spinal fractures, spinal fusion procedures. In severe cases tongs are applied to the skull for stabilization.
This involves the application of different and increased traction force that are alternately applied and released (hold / rest), by electronic means. The treatment time is 15 minutes to half an hour, with variation in hold time and relax time. This is an inexpensive and non invasive treatment that produces surprisingly good result in some, even avoiding surgery.
If the head is on the table with the cervical spine in a neutral or extended position, traction will exert
its maximal effect interiorly on the inter vertebral structure.
However, if the head is maintained in a flexed position. It will expert pulling effect on the posterior structures.
The greater the angle of flexion, the lower in the cervical spine is the area affected by the traction force.
