Question

How should the EMT properly assess muscle strength in the upper extremities?

1) The patient should be able to flex and extend all fingers.
2) The patient should be able to feel you touching each finger.
3) Have the patient grip your hands simultaneously.
4) Have the patient grip your hands, one at a time.

Answer 1

To assess muscle strength in the upper extremities, an EMT can perform tests such as contracting muscles against resistance and checking for lateral differences in strength.

Step-by-step explanation:

To properly assess muscle strength in the upper extremities, an EMT can perform various tests. One method is to have the patient contract muscles against resistance, such as lifting the arm while the EMT pushes down on it. Another method is to test for lateral differences in strength, which can indicate deficits in the corticospinal tract. Additionally, the EMT can check for pronator drift, where the patient unconsciously allows one arm to slowly relax, indicating a motor system failure to maintain the supinated position.
