Estim Muscle Contraction Flashcards
T/f Muscle contractions produced by ES are not identical as physiological contractions
TRUE
What are the six things ES contractions can do
Strengthen muscle
Improve muscular endurance
Improve cardiovascular health
Prevent muscle atrophy
Reduce spasticity
Help restore function
In an innervated muscle, what fibers are physiologically activated first
Slow twitch type 1 fibers
In an innervated muscle what fibers are electrically stimulated second ?
Fast twitch type II muscle fibers
T/f during a contraction, physiologically the contractions are smooth
True
T/f during a contraction, electrically the contractions are rapid and jerky
True
What characteristics type I muscle fibers ?
Small
Slow twitch
Produce dec. force contraction
More resistant to fatigue and atrophy
What characteristics are type II muscle fibers
Larger
Fast twitch
Produce inc force and quicker contraction
Fatigue rapidly
Prone to weakening and atrophy with disuse
What effect on muscle fibers does ES have ?
Strengthen muscle fibers that have been atrophied from disuse
In a denervated muscle what happens when es is applied
Muscle no longer contracts physiologically or with electrical stimulation
What can ES do to a denervated muscle nerve growth
Slow it down
What are some clinical applications to apply ES for muscle contraction
Orthopedic conditions
Cardio respiratory
Healthy adults and athletes
Muscle coordination and motor control for patients w neurological conditions
What is AMI
Atherolgenic muscle inhibition, causes shut down of muscle
When a person gets a TKA, the quads shut down, what fibers atrophy?
Type II fibers
How can patients with OA benefit from estim
Decrease pain
Increase strength
Improve walking
Improve climbing
How Can patient who have RA benefits from estim
Improve strength
Improve endurance
Patients who had heart failure and applied NMES to their quads benefited from what ?
Peak O2 uptake
6 min walks test distance
Muscle strength
Depressive symptoms
Quality of life
What athletes improves strength from estim
Rugby players
Hockey players
Tennis players
Soccer players
Gymnasts
Basketball players
Vollyball players
PE students
Following a stroke, NMES can do what?
Reduce shoulder subluxation
Reduce spasticity
Other than ES applied through current and pads, is there other forms it can be applied ?
Yes there is different divides such and hand devices, knee devices
What neurological disorders can NMES benefit
Spinal cord injury
Multiple sclerosis
Cerebral palsy
Dysphagia
Urinary incontinence
What is a precaution for ESTIm for muscle contraction .
DOMS
When applying EStim how should the patient be positioned
Never want them laying on the electrodes
Where do the electrodes get placed for muscle contractions
One electrode over motor point
One on the muscle to be stimulated
