PROPERTY OF PIMA COUNTY JTED, 2010 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 PROPERTY OF PIMA COUNTY JTED, 2010

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 4/28/2017 Property of CTE Joint Venture

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 4/28/2017 Property of CTE Joint Venture
