4. Terminology
electrical stimulation (E-Stim) – using electricity to target a motor nerve and cause a muscle response
transcutaneous electrical nerve stimulation (TENS) – using electricity to target a sensory nerve to decrease pain

Think-Pair-Share
What are the similarities between E-Stim and TENS? What are the differences between the 2?
3. Think-pair-share
teacher presents a question
teacher gives wait time for student to form answer
teacher instructs students to share their answer with a partner
teacher calls on non-volunteers to share with the class

7. E-Stim and TENS Comparison
Similarities
1. Both are electrical modalities
2. Both transmit electricity through electrodes
3. Both stimulate nerves
4. Both produce therapeutic effects
Differences
1. E-Stim is used to stimulate motor nerves; TENS stimulates sensory nerves
2. E-stim produces muscle contractions; TENS controls pain
3. An E-stim unit can function as a TENS

8. How Electrical Stimulation Units Work
The unit generates an electrical current
The current is transmitted by the electrodes (two or more electrodes are required to complete an electrical circuit)
The electrodes are placed on the skin
The current carried by the electrodes is used to stimulate a nerve (sensory or motor)
The amount of electricity is controlled to produce a therapeutic effect
