12- Mobility Rehabilitation

Question 1

What are some possible causes of short step length?

Answer 1

a. weak pushoff prior to swing b. weak hip flexors at toe-off and early swing c. above-normal knee extensor activity during pushoff d. excessive deceleration of leg in late swing

Question 1

What is involved with stability when it comes to intervention at the strategy level?

Answer 1

• control of the head, arms, and trunk (HAT) - use of assitive devices - extensor support moment - foot placement at initial contact - balance during double and single-limb support

Question 2

What does the effect of strength training on gait performance show?

Answer 2

a nonlinear relationship between gait speed and strength in lower extremity muscles

Question 3

What are some limitations of functional gait measures?

Answer 3

• indicators of the end of project only - do not provide insight into underlying impairments

Question 3

What can cause weak pushoff prior to swing?

Answer 3

below-normal plantar-flexor moment or power generation or EMG during pushoff

Question 4

What are some standard measures of functional activity when it comes to temporal and distance parameters?

Answer 4

• gait velocity - 6 or 12 min walk test - technological devices (force place, EMG)

Question 5

True or False: resolution of impairments alone may not be enough to ensure recovery of functional ambulation skills

Answer 5

True

Question 7

What is the level of mobility disability?

Answer 7

restriction in PARTICIPATION of mobility related activities in the person’s home and community environment

Question 7

What can cause excessive deceleration of leg in late swing?

Answer 7

above-normal hamstring EMG or knee flexor moment or power absorption late in swing

Question 7

What has beneficial effects on gait parameters, especially in the frail elderly group with slow walking speed?

Answer 7

exercise and strength training (high intensity) programs

Question 8

What are the limitations to visual gait analysis?

Answer 8

Poor reliability Time-consuming

Question 9

What are functional mobility skills?

Answer 9

mobility within a standard setting (eg., clinical environment)

Question 11

How do you measure participation when examining at the functional level?

Answer 11

• self-report measures of mobility participation - activity measures (like pedometer)

Question 14

What are some examples of OGA?

Answer 14

-Rancho los Amigos Gait Analysis Form -Gait Assessment Rating Scale -Rivermead Visual Gait Assessment

Question 15

_______ at the _______ level is essential.

Answer 15

training at the strategy level

Question 16

What ate the 3 main concepts when it comes to gait and mobility?

Answer 16

1. Progression 2. Stability 3. Adaptation

Question 17

What are some examples of adaptation when it comes to intervention at the strategy level?

Answer 17

-obstacle courses -forward/backward/sideways -anticipation of potential balance threats

Question 18

What can cause weak hip flexors at toe off and early swing?

Answer 18

below normal hip flexor moment or power or EMG during late pushoff and early swing

Question 19

What can cause above normal knee extensor activity during push off?

Answer 19

above normal quadriceps EMG or knee extensor moment of power absorption in late stance

Question 20

What is the most commonly used clinical tool to assist the therapists in analyzing a patients gait strategies in a systematic way?

Answer 20

Observational Gait Analysis (OGA)

Question 21

The relationship between impairments and gait parameters is very complex and depends on many factors such as:

Answer 21

• the type and extent of impairment - the functional level of the patient - the capacity for compensation by other systems

Question 22

What does progression involve when it comes to intervention at the strategy level?

Answer 22

-energy generation -advancement of the swing leg/foot clearance

Question 23

No matter what skills to work on with clients, it is critical to _______.

Answer 23

vary the tasks and environmental demands early on

Question 24

What are some assessment tools for examining mobility?

Answer 24

1. dynamic gait index 2. functional gait assessment 3. Rivermead mobility index 4. Emory functional ambulation profile 5. physical performance and mobilitly examination

Question 25

Who is important in gait analysis?

Answer 25
