Study Notes
Electrical Current and Muscle Contractions
- The electrical current waveform characterized by a flow of charged particles through a conductor in response to an applied electrical field is known as electric current.
- Parameters used to describe electrical currents include amplitude, frequency, wavelength, and threshold.
Muscle Contractions
- The principle that states the intensity of electrical stimulation needs to be greater than the physiological threshold to produce muscle contractions is known as the threshold principle.
- Clinical applications of electrically-stimulated muscle contractions include muscle strengthening and rehabilitation, muscle re-education, and management of muscle weakness or paralysis.
Electric Current
- The term that refers to the flow of charged particles through a conductor in response to an applied electrical field is electric current.
