PHYSIOLOGICAL EFFECTS

The principal effect of SWD on the body is the production of heat in the tissues due to the rise of temperature.1. Increased metabolism:•Heating tissues accelerates chemical changes such as metabolism, so oxygen and food stuffs are used up.•With increased metabolism, there will be increased output of waste products.

2. Increased blood supply:•As a result of increased output of waste products such as metabolites, which act on the walls of the capillaries and arterioles, these tissues dilate.•In addition, heat has direct effect on blood vessels, causing vasodilatation.•Heat also produces stimulation of superficial nerve endings, causing reflex dilatation of the arterioles.

3. General rise of temperature:

•As blood passes through the heated tissues, it also becomes heated and carries the heat to other body parts.

•Rise of temperature induces muscle relaxation and increases the efficiency of muscle action.

4. Fall in blood pressure:

•The generalized vasodilatation reduces the peripheral resistance to blood flow.

•Heat also reduces blood viscosity, which helps in the reduction of blood pressure.

5. Increased activity of sweat glands:

•If a general rise of temperature occurs, there will be increased activation of the sweat glands.

Therapeutic Uses

1.1. Effect on InflammationEffect on Inflammation

Assist in removal of Waste Products

All these effects bring about resolution of inflammation

2. Effect on Bacterial Infection2. Effect on Bacterial Infection

• Inflammation is normal response of Body to bacteria

•Heating the tissue auguments these changes so reinforces body's normal mechanism to of dealing with infecting organisms

Ex. Boils, Carbuncles, Abscesses.

3. Traumatic Conditions3. Traumatic Conditions

Healing

4. Reducing Healing time4. Reducing Healing time• Increased Blood supply• More Nutritive Material

•More O2 supply

5. Relief of Pain5. Relief of Pain
