Tennis Elbow is a condition that commonly affects professional to recreational tennis players. Tennis elbow is referred to as lateral elbow tendinopathy (LET) in clinical practice. This study was conducted to test the effectiveness of iontophoresis treatment on patients with LET. Iontophoresis is defined as a treatment that uses an electric charge to move liquid medication into the body or specific targeted area of a muscle or inflamed area. The liquid is known as dexamethasone and is negatively charge so the electric current draws the negatively charged medication into the skin. This process is commonly used in physical therapy practice to treat all kinds of inflammatory conditions, all from the basic principle that the medication is negatively charged and an electric current draws it into the body. The medication is an anti-inflammatory steroid used to treat inflammation and in this case muscle tenderness …show more content…
The positive electrode will get an acid accumulation because the chloride ions will be attracted to the positive charge. The negative side will have an alkaline accumulation because the sodium hydroxide in the batter will be attracted to the negative side of the battery. This process of attraction makes a current and draws the medication into the skin. This is interesting because it a very simple principle in chemistry. The greater the current or the stronger the reaction the greater the input of medication will be. The longer the iontophoresis is on the stronger the reaction will be. The third way to increase the effectiveness is through tissue resistance which increases the medication distribution. With the simple principle of electric charge and negatively charged medication, Iontophoresis evenly distributes the steroid throughout the
