NMES

Question 1

what are the indications to perform NMES?

Answer 1

Indications:
Prevent/Slow muscle atrophy
Increase range of motion
Perform muscle re education
Reduce muscle spasticity
Increase local blood circulation
Muscle Strengthening
Improve functional movements

Question 2

what are the contraindications?

Answer 2

pacemaker
osteomyelitis
malignant tissue
metal in the area of application
uncontrolled hypo/hypertension
vascular disorders
over broken or irritated skin
along the carotid sinus/neck area

Question 3

when should you use NMES for patients

Answer 3

Use of NMES/FES in patients with
neurologic conditions is based on
having an intact peripheral innervation
to target muscles (Upper Motor neuron
injury)

Question 4

what are the four principals of electricity?

Answer 4

1. there are two charge- positive and negative
2. Like charges repel while opposites attract.
3. energy can neither be created nor destroyed
4. energy can be transferred from one object to another

Question 5

what is Ohm’s law?

Answer 5

I=v/r
current=voltage over resistance

Question 6

what is a conductor

Answer 6

Water, metals, muscles, nerves =
conductors materials that allow easy
movement of electrons or ions

Question 7

what is an insulator?

Answer 7

Rubber, plastic, fat = insulators hinder
movement of electrons and ions

Question 8

describe current and what is its relationship to resistance and voltage?

Answer 8

Current: movement of ions/electrons
in response to voltage force (ampere)
*
Current flow is directly proportional to
the magnitude of the voltage force
*
Current is the quantity of electrons or
ions flowing at a given time; universal
symbol = I and unit of measurement is
the ampere or amp (A) or milliamp mA
*
Resistance is opposition to the flow of
current

Current (I in amperes) is directly proportional to the voltage
force (V) pushing the current and inversely proportional to
resistance (R) to the voltage

Question 9

what does ohms law tell us?

Answer 9

Ohm’s law tells us that the more resistance there is to the flow of current, the less current there will be.

Question 10

what tissues in the human body have higher resistance or lower resistance?

Answer 10

Skin ■Hair ■Fascia ■Ligament ■Callus ■Fat ■Bone ■Tendon ■Scar
