Special Populations - athletes

Question 1

what is common to see in prosthetic running

Answer 1

• circumduction/vaulting
• increased compensation
• difficulty to maintain posture
• hard to stop

Question 2

step 1 of prosthetic running

Answer 2

• trust the prosthesis

Question 3

step 2 of prosthetic running

Answer 3

• hip extension
• need adequate hip ext ROM and strength to pull through stance phase
• causes speed and power
• loads the forefoot of prosthesis
• increased contralateral stride length

Question 4

step 3 of prosthetic running

Answer 4

• stride symmetry
• equal and relaxed strides
• appropriate pace

Question 5

step 4 of prosthetic running

Answer 5

• arm carriage

- appropriate arm movements

Question 6

implications of prosthetic sprinting

Answer 6

• decreased symmetry during start
• acceleration phase requires continuous adaptation by the runner
• bilateral implications

Question 7

what is a problem when a prosthetic runner does more than 200m

Answer 7

• turns, which creates more compensations

- prosthetic set up

Question 8

compared to able bodied sprinters, prosthetic sprinting does what

Answer 8

• increased demand in muscle work
• asymmetrical stride length, stride time and impact loads
• more energy expenditure
• increased mechanical work on sound limb
• change in mechanics
• ~10% reduction in force

Question 9

advantages of prosthetic cycling

Answer 9

• can be started earlier than running
• may not require specialized prosthesis
• low impact
• can allow for balance loss

Question 10

common modifications for prosthetic cycling

Answer 10

• pedal systems
• shortened, wider crank
• recumbent bikes

Question 11

what other sports can amputees participate in

Answer 11

• swimming
• golf
• skiing
• many others

Question 12

main takeaways for these athletes

Answer 12

• team effort
• risk of overload
• finish with normal rehab before progressing, have a mature limb
• running blades dont increase performance
• unlimited options for athletic involvement
