1. Which of the following could lead to a poor solution by the neuromuscular system as it attempts to accomplish the task of walking?

2. It is the lambda at the _____ ankle that was found to be strongly correlated with the patient’s prosthesis preference.

3. The prosthetic ankle in the transtibial amputee is the sole joint that is directly influenced by the biological system and the mechanical system.

4. Gait asymmetry is one of the main concerns in unilateral lower limb amputees to avoid exertion of excessive load on the sound limb.

5. Which of the following can relieve the distal end pressure by applying more loads to the proximal tissues of the residual limb?

6. To compensate for higher loading on the intact limb, transtibial amputees have which of the following?

7. This study found that pistoning values were significantly different among the suspension systems during level walking in the _____ phase.

8. The participants showed higher first peak value for the sound limb with the:

9. Which of the following exhibited more homogenous cadence values between the legs?

10. This study showed a significantly higher magnitude of hip ROM with the sound leg than the prosthetic leg.

11. It may be concluded from the overall findings that _____ can be used clinically as an alternative for lower limb amputees.

12. When people with a leg amputation use a passive-elastic prosthesis, and walk at faster speeds, they experience greater kinematic and kinetic leg asymmetries, including greater unaffected leg forces.

13. Passive-elastic prostheses release less than one-half the mechanical energy, and less than _____ the mechanical power normally generated by the soleus and gastrocnemius during the stance phase of level-ground walking at moderate speeds and are therefore unable to replicate the function of a biological ankle.

14. There were statistical differences in unaffected leg loading rates for GRFs and knee EAMs when subjects used the powered prosthesis compared to the passive-elastic prosthesis.

15. At slow walking speeds, the passive-elastic and powered prostheses, as well as the biological ankle behave in a spring-like manner, where the net mechanical work is nearly zero across the entire _____ phase.

16. The results of this study show that use of a powered ankle-foot prosthesis decreases the unaffected leg peak impact resultant:

17. At the walking speed closest to preferred, subjects with an amputation using a powered ankle-foot prosthesis reduced their unaffected peak knee EAM by over:

18. Which of the following was the only muscle with a variance-to-signal ratio significantly greater in the amputee group compared to the control group?

19. All amputee subjects were able to differentiate tibialis anterior and gastrocnemii activation during volitional maximum activation.

20. The inter-subject variability in the biceps femoris and gluteus medius activation shape observed in the amputee subjects suggests that there are differences in compensatory muscle recruitment patterns used by transtibial amputees during walking.
