Study Notes
Electrotherapy Introduction
- Electrotherapy is the use of electrophysical agents for both treatment and evaluation purposes.
- The use of electrotherapy dates back to ancient Greece; Largus used eels and torpedo fish for gout treatment.
- In the 1780s, Luigi Galvani discovered that frog's gastrocnemius muscle contracted with electricity.
- Alessandro Volta discovered the Voltaic pile in 1800, which generates current flow from the contact of two metals.
- Galvani and Volta laid the foundation for modern electrotherapy.
General Effects of Electricity
- Heat: Electrical current produces heat.
- Chemical: Electrical current can alter chemical reactions.
- Physiological: Electrical current has effects on living organisms.
- Mechanical: Electrical current can cause movement.
- Electromagnetic: Electrical current generates electromagnetic fields.
Atomic Structure
- The atom is the smallest unit of a chemical element.
- The atom is composed of a nucleus and an electron cloud.
- The nucleus contains protons and neutrons.
- Proton count determines the element and dictates the atom's neutrality or electrical charge.
- Atoms with an equal number of protons and electrons are electrically neutral.
- Atoms lose electrons due to electrical stimulation to become electrically positive.
- Atoms gain electrons due to electrical stimulation to become electrically negative.
- Atoms with eight electrons in their outer shell are considered saturated.
- Low voltage currents are characterized by 150V and short pulse duration.
