- 1What is muscle stimulation?-using electricity to make a muscle contraction and relaxation
- 2define atom- a neutral with a central nucleous proton and electron
- 3define ionan atom that has become charged
- 4what is a conductor?assists the flow of electrons
- 5what is an insulatorresists the flow of electrons
- 6what is impedance?tissues ability to allow electricity flow
- Resistance of the tissue to the electrical current - 7Is skin impedance high or low?skins resistance (impedance) is high
- 8what is the best impedance for skin?warm moist skin
- 9define amplitudemax intensity in one phase
- 10define chargetotal amount of electrons in one phase. strength of the machine
- 11Define the ALL or NONE principleall motor neurons reach there threshold level and fire all at once, or not at all
- 12what is the different from a involuntary muscle stim contraction and an actual active voluntary contraction ?muscle stim- depolorization occurs and motor neurons fire all at once making it un coordinated and not smooth can lead to cramping and fatigue faster , muscles fire opposite to active contraction
Active contraction- coordinated smooth, fire normally, fatigue not as quickly - 13define accommodationautomatic rise in threshold of excitation resulting from gradually increasing the stimulus
- 14what is another name for muscle stim electrodes:active(cathode)
negative, inactive/positive (cathode) - 15where do u place electrodes to get a deeper currentfarther apart
- 16Name the 4 levels of intensity that muscle stim produces1.subsensory
2. sensory
3. motor
4. noxious - 17Name contraindications for Muscle stim1. pace maker
2. over carotid sinus
3. over reproductive organs
4. over rib cage
5. over bruises - 18name precautious for muscle stim1. obesity
2. decrease in sensation
3. decrease in circulation
4. metal
5. unreliable clients - 19name the 3 ways the muscle stim currents can be classified as:1. alternating current
2. direct current
3. pulsed current
