|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
