Gait - Effects on Posture and Gait While Walking and Texting

Texting and Walking: Strategies for Postural Control and Implications for Safety

1. The summed absolute distance in lateral direction per meter walked was less during texting than reading on a mobile phone or normal walking.

A. True B. False

2. All of the following are true with regard to the global frame of reference, except for:

A. Head flexion-extension ROM was less during reading and texting than walking without the phone. B. Head lateral flexion ROM was less during reading than walking. C. Head rotation was greater during reading and texting than walking. D. Thorax flexion-extension ROM was less during reading and texting than walking.

3. Thorax lateral flexion ROM decreased more during which of the following?

A. Texting B. Reading C. Walking D. Thorax lateral flexion ROM decreased equally for all of the above

4. Evaluation of gait performance revealed that individuals do which of the following during texting and reading than unconstrained walking?

A. Demonstrate greater absolute medial-lateral step deviation. B. Walk with a flexed head position. C. Move the thorax and head more in-phase with reduced phase variability. D. All of the above.

5. The current study found an increased medial lateral head motion of _____ during texting and reading.

A. Approximately 2.5 degrees B. Approximately 2.0 degrees C. Approximately 1.5 degrees D. Approximately 1.0 degree

6. Increased medial-lateral head motion is associated with a greater risk of falling in healthy older adults and individuals with Parkinson's disease.

A. True B. False

7. A key finding was reduced neck ROM (head relative to thorax) in all planes during reading, and to a greater extent with typing text.

A. True B. False

8. Reduced arm swing can negatively impact walking balance in which of the following ways?

A. Arm swing reduces angular momentum about the vertical axis. B. Arm swing reduced the metabolic cost of walking. C. Arm swing assists with recovery after disturbance to walking balance. D. All of the above.

Does Texting While Walking Really Affect Gait in Young Adults?

9. In regards to Spatio-temporal parameters, all of the following are true except?

A. Texting while walking slowed subjectsâ€™ gait speed, reducing both their cadence and stride length. B. Double support period and CV of stride time increased while texting. C. During the duration of the sub-phases of stance, the flat foot contact decreased. D. During the duration of the sub-phases of stance, the push-off decreased.

10. The results of the study reported did not reveal any significant alterations of the ankle and knee joint kinematics.

A. True B. False

11. Results from the current study showed that the ankle muscle co-contractions decreased during which of the following?

A. The H-phase, roughly corresponding to load response B. The F-phase, mid-stance C. The P-phase, terminal stance D. All of the above

12. Overall, the authors of the study presented feel that gait modifications due to texting while walking are minimal in young adults indicating that texting while walking is a safe dual task activity.

A. True B. False
