Nems

Question 1

what is neuromuscular electrical stimulation (NMES)

Answer 1

causes muscle contraction through electrical stimulation

Question 2

what are the benefits of nems

Answer 2

can improve muscle strength and endurance for individuals who cant perform a a high intensity, can decrease pain, can be used when immobile

Question 3

what are some limitations of nems

Answer 3

increased muscle fatigue vs voluntary movement, less muscle activation than voluntary, could be painful for individual, expensive

Question 4

what examples could nems be used for

Answer 4

Post acl surgery, hamstring strain rehab, ankle sprain recovery,

Question 5

how does it work compared to a voluntary contraction

Answer 5

nems - pulse is delivered through electrode which causes muscle contraction
voluntary- muscles receive a pulse from CNS through the motor nerve cells which are connected with the muscle fibre

Question 6

what are some factors that influence electrical stimulation

Answer 6

electrode placement, condition of muscle,

Question 7

contraindications for nems

Answer 7

bleeding tissue, acute fracture, infection, skin condition, malignancy, epilepsy

Question 8

considerations for nems

Answer 8

dont handle while electrodes are on, dont use on open wounds, dont apply to head, neck, chest could disrupt rhythm

Question 9

what are the different modes used for

Answer 9

mode 1- 2 blood flow
mode 3-4 pain
mode 5-6 endurance
7-8 muscle conditioning
mode 9 - power/strength
