Final Flashcards
what is NMES
a way to generate contractions for people who have a reduced ability to voluntarily contract skeletal muscle by using electrodes placed on the skin
What is the difference between NMES and FES
NMES is anytime stimulation is applied for the purpose of improving muscle quality or function
FES is when stimulation is used to assist a functional movement
How does NMES create smooth contractions
summation of small twitches
What are the disadvantages of NMES (5)
not everyone can use it
no muscle recruitment specificity
power source required
random muscle fibre recruitment
shaving stimulation surfaces required
Who cannot use NMES
SCI injuries below t12-l1
-this is because the spine down there is the caudal equine which is no longer whole neurone and is just axons. If they are damaged they will die which removes the nerves that NMES uses to activated muscles.
SCI injuries above t6
- can trigger autonomic dysreflexia. This means that NMES can cause an episode of high BP from sympathetic hyperactivity.
-irregular sign is reduced heart rate
what is the difference between the terms ‘deaf’ and ‘Deaf’
deaf is a medical perspective term that implies that deaf people are not as available.
Deaf is a cultural perspective term that implies Deaf people and sign language are just as capable.
what are common obstacles for Deaf people in sport (7)
excessive background noise
distance from person speaking
reverberation
low confidence
mental health issues
difficulty understanding others
social issues
what are some examples of assistive hearing devices (4)
hearing aids
bone anchored hearing aid
cochlear implants
FM systems
what do assistive hearing devices do
amplify and enhance speech
louder not clearer
What is Deaf Gain
a shift away from the pathological focus and towards the idea that Deaf people are valuable and have potential to contribute to the greater good of humanity
what is ocularcentrism
valuing of vision over other senses in western cultures
What was the Soundscape documentary about
it was about a visually impaired man who climbs mountains. It emphasises the point that people with visual impairments can still enjoy activities and experiences the same way an unimpaired person can. While they may experience it in a different way, it is still just as meaningful and important.
what is visual acuity
central vision. usually expressed in a x/20 scale. ex. 20/20
some common problems involving visual acuity is myopia, hyperopia, astigmatism
what is visual field
peripheral vision
what is macular degeneration>
the breakdown of the macula. This affects the central field of vision.
risk factors: ageing, smoking and heredity
what is glaucoma
fluid pressure on the optic nerve reduces peripheral vision.
risk factors: age, heredity
what is cataracts
clouding of the lens due to chemical change in lens
risk factors: ageing, medication, heredity
what is diabetic retinopathy
damage to retina from diabetes and blood sugar levels
what are the factors influencing physical activity participation for people with visual impairments (4)
age of onset
acquired or congenital
communication methods
sporting opportunities
what is the cultural language model term for people who have undergone an amputation
amputee
after an amputation, what is the name of the part of the limb left after?
stump (casual), residual limb (medical term)
what is the goal in an amputation surgery?
a balance between post surgery healing and prosthetic fitting
what conditions commonly lead to amputation (6)
trauma, tumors, infection, peripheral vascular disease (most common), diabetic neuropathy (indirect), congenital defects
what are some pain related concerns after amputation (3)
residual limb pain (related to bone growth, prosthetic use and nerve issues- neuroma) , back pain, phantom limb pain.
what are some skin problems after amputations (3)
erosion/abrasion/blisters, ulcerations, skin infections
what are some non skin or pain related problems after amputations (5)
circulatory disturbances, local osteopenia, muscle atrophy, edema, psychological and social adjustment
