NMES
| Question | Answer |
|---|---|
| What is neuromuscular electrical stimulation | The use of electricity to stimulate the nerves that correspond to a targeted mm or mm group & cause it to contract. |
| What are the physiological requirements for effective tx of NMES | Requires an intact peripheral nerve & healthy mm tissue |
| Clinical indication for NMES | (1.) retard or prevent disuse atrophy (2.) mm re-education (3.) maintain or increase jt mobility (4.) increase local blood circulation (5.) relax mm spasm (6.) prevent thrombosis in calf immediately after surgery |
| Contraindications | PT CUP - Pacemaker, thrombosis, carotid sinus, unstable arrhythmias, pregnancy |
| Precautions | IC Mosi - Iontophoresis, cardiac disease, malignant tumor, open wounds, skin irritation, impaired mentatation or sensation |
| Waveform selections | symmetrical & Asymmetrical |
| What are symmetrical wave forms used for | Large mm |
| What are asymmetrical wave forms used for | Small mm |
| What size should the electrode be | Largest electrode that provides desired response w/o causing overflow to other mm |
| which electrode is more active in the symmetrical wave form | Both are active |
| which electrode is more active in the asymmetrical wave form | the negative |
| Where should the negative electrodes be placed for either wave form | over the motor point |
| What is a motor point | Place in the mm where electrical stimulation will produce the greatest contraction w/the least amount of electricity, generally over the middle of the mm belly |
| The greater the distance between electrodes determines | a deeper current flow |
