12- Mobility Rehabilitation Flashcards
What are some possible causes of short step length?
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
What is involved with stability when it comes to intervention at the strategy level?
- 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
What does the effect of strength training on gait performance show?
a nonlinear relationship between gait speed and strength in lower extremity muscles
What are some limitations of functional gait measures?
- indicators of the end of project only - do not provide insight into underlying impairments
What can cause weak pushoff prior to swing?
below-normal plantar-flexor moment or power generation or EMG during pushoff
What are some standard measures of functional activity when it comes to temporal and distance parameters?
- gait velocity - 6 or 12 min walk test - technological devices (force place, EMG)
True or False: resolution of impairments alone may not be enough to ensure recovery of functional ambulation skills
True
What is the level of mobility disability?
restriction in PARTICIPATION of mobility related activities in the person’s home and community environment
What can cause excessive deceleration of leg in late swing?
above-normal hamstring EMG or knee flexor moment or power absorption late in swing
What has beneficial effects on gait parameters, especially in the frail elderly group with slow walking speed?
exercise and strength training (high intensity) programs
What are the limitations to visual gait analysis?
Poor reliability Time-consuming
What are functional mobility skills?
mobility within a standard setting (eg., clinical environment)
How do you measure participation when examining at the functional level?
- self-report measures of mobility participation - activity measures (like pedometer)
What are some examples of OGA?
-Rancho los Amigos Gait Analysis Form -Gait Assessment Rating Scale -Rivermead Visual Gait Assessment
_______ at the _______ level is essential.
training at the strategy level
What ate the 3 main concepts when it comes to gait and mobility?
- Progression 2. Stability 3. Adaptation
What are some examples of adaptation when it comes to intervention at the strategy level?
-obstacle courses -forward/backward/sideways -anticipation of potential balance threats
What can cause weak hip flexors at toe off and early swing?
below normal hip flexor moment or power or EMG during late pushoff and early swing
What can cause above normal knee extensor activity during push off?
above normal quadriceps EMG or knee extensor moment of power absorption in late stance
What is the most commonly used clinical tool to assist the therapists in analyzing a patients gait strategies in a systematic way?
Observational Gait Analysis (OGA)
The relationship between impairments and gait parameters is very complex and depends on many factors such as:
- the type and extent of impairment - the functional level of the patient - the capacity for compensation by other systems
What does progression involve when it comes to intervention at the strategy level?
-energy generation -advancement of the swing leg/foot clearance
No matter what skills to work on with clients, it is critical to _______.
vary the tasks and environmental demands early on
What are some assessment tools for examining mobility?
- dynamic gait index 2. functional gait assessment 3. Rivermead mobility index 4. Emory functional ambulation profile 5. physical performance and mobilitly examination
