NMES

Question 1

how to perform

Answer 1

identify clean area, contraindications, pin prick test, place electrodes, attach leads, set frequency/pulse/time, try intensity, start timer for 15 mins (x4 daily), encourage P to watch muscle contracting, work with it, bridge the gap
adverse reactions, teach to do x4 daily

electrodes placed on motor point/either end of muscle belly, should feel like a tingling
pulse - 300us
frequency - 40Hz
on/off - 8/5 sec
ramp 1

modify - decrease intensity, increase rest time
progress by bridging the gap - P maintains contraction during rest time

Question 2

contraindications / precautions

Answer 2

MSK: Neoplastic tissue/tumour, after X-ray therapy, pregnancy
CR:
CV: pacemaker, peripheral VD
N: undiagnosed pain, can’t understand instructions,
driving, skin irritation
not over carotid sinus/mouth/trachea

Question 3

rational

Answer 3

is a pulse generator that sends electrical impulses through electrodes to stimulate nerves + contract a muscle group by mimicking the action potential coming from the CNS
strengthening motor paths by encouraging P to work with + bridge the gap

Question 4

physiological affects

Answer 4

signals mimick CNS causing contraction, recruits more muscle fibres, applies resistance
watch it - motor learning by reinforcing neural pathways, sensory feeling improving motor control
increases muscle strength, decrease muscle spasm, disuse atrophy, blood supply, RoM

Question 5

structures

Answer 5

muscle, nerve
deltoid, axillary nerve
quadriceps (vastus medialis + lateralis), femoral nerve
tibialis anterior, common peroneal nerve

Question 6

principles

Answer 6

do not immerse in water
electrodes placed on motor point/either end of muscle belly
care of electrical equipment
aware of patient discomfort
