| The number of wave forms being emitted by the electrical stimulating unit in one second. | frequency |
| message technique in which the fingers and thumbs move in circular patterns, stretching the underlying tissue and thus | friction |
| direct electrical currents that can flow continuously or intermittently | galvanic current |
| alternating vasoconstriction and vasodilation in the body's effort to prevent tissue damage from cold | hunting reaction |
| the voltage output of the stimulation unit | intensity |
| process whereby ions in solution are carried through the intact skin by an electrical current | iontophoresis |
| lack of blood supply to a body part | ischemia |
| systematic manipulation of the soft tissue | massage |

| the ability of the electrical stimulating unit to change or alter the magnitude or duration of a wave form | modulation |
| momentary loss of function caused when cold is applied to a part that has motor nerves close to the skin | nerve palsy |
| resistance to the passing of an electrical current along a conductor | ohms |
| rare disease that occurs minutes after cold exposure; may lead to renal dysfunction, hypertension, and coma | peroxysmal cold hemoglobinuria |
| message technique in which soft tissure is held between the thumb and forefinger and is alternately rolled, lifted, and twisted to loosen tissue and stimulate drainage | petrissage |
| electrical current produced by applying pressure to certain crystals such as quartz | piezoelectrical effect |
| refers to the direction of current flow | polarity |
| the transfer of heat through space from one object to another | rediation |

| message technique using cupping, hacking, and pinching movements | tapotement |
| application of heat to treat disease and traumatic injuries | thermotherapy |
| small hyperirritable are within a muscle in which nerve impulses bombard the central nervous system and are expressed as a referred pain; may be active or latent | trigger point |
| closing of blood vessels | vasoconstriction |
| opening of blood vessels | vasodilation |
| rapid shaking of tissue either manually or with a mechanical vibrator | vibration |
| force that moves current along a conductor: 1 volt is the amount of electrical force required to send a current of 1 amp through a resistance of 1 ohm. | voltage |
