Quiz - Categorization of Activities of Daily Living of Lower Limb Amputees During Short-Term Use of a Portable Kinetic Recording System: A Preliminary Study, Laurent Frossard, PhD, et al.

1. True or false __________It was determined that pedometers are accurate to detect distinct gait cycles, and they provide a complete description of the level of intensity and type of activities, particularly the ones that are not derived from steps.

2. [Select the correct response.] Studies focusing on other populations completed analysis of the raw data by implementing a(n) __________recognizing typical patterns of certain ADL, such as lying, sitting, standing, level and incline walking and ascending and descending stairs.

A. Biorhythm

B. Formula

C. Algorithm

3. [Select the correct response.] The analyses conducted have the potential to render a more comprehensive and realistic insight into the actual functional outcome, provided that the population involved __________.

A. Presents tremendous variability of kinematic patterns

B. Presents small variability of kinematic patterns

C. Presents moderate variability of kinematic patterns

4. [Select the correct response.] The purpose of this preliminary study was to determine the relevance of the categorization of the __________.

A. Load regime data

B. Raw load data

C. Kinematic pattern data

5. True or false __________During the procedure, the prosthetic leg was worn approximately 30 minutes before recording to ensure subject confidence and comfort.

6. [Select the correct response.] Which of the following categories of activities was not used for load?

A. Localized locomotion

B. Stationary loading

C. Reverse loading

D. Directional locomotion

E. Inactivity

7. True or false __________Approximately half of the total impulse of the resultant force was due to directional locomotion.

8. [Select the correct response.] The overall cadence was__________ strides/minute, but the more meaningful cadence during directional locomotion was __________strides/minute.

A. 10…47

B. 12…53

C. 15…45

9. True or false __________Localized locomotion is considered more of an in-between activity, which is difficult to validate.

10. [Select the correct response.] This article highlighted the __________of achieving appropriate assessment of the true functional output and usage of the prosthesis with typical resources available in clinical settings.

A. Ease

B. Difficulty

C. Usefulness

11. [Select the correct response.] From a(n) __________point of view, this study corresponded to a(n) __________study.

A. Scatological…. empirical

B. Engineering…proof-of-concept

C. Scientific…trial-and-error

12. True or false __________The proposed categorization can be done regardless of the attachment, providing that the transducer can be mounted within the prosthesis above or below the knee.
