- Front
- Back
|
Medial & Superior Nuclei
|
- mediate vestibulo-ocular reflexes
|
|
|
Inferior Nuclei
|
- projects to Medial Vestibulospinal tract
- reflex control of neck muscles |
|
|
What Are Qualitative Methods of Description?
|
- observational (FGA)
- used in clinical settings - subjective in that it is based on the skills of the observer/rater - Kinetics |
|
|
What Are Quantitative Methods of Description?
|
- primary focus in Biomechanics
- more objective - Kinematic Analsysis |
|
|
What is Kinematic Analysis?
|
description of the type of motion observed:
- angular vs linear - displacement - velocity - ranges of motion - acceleration |
|
|
What is Kinetics?
|
used to measure forces and causes of motion:
- force plates - forces about joints - movements of force (torque) |
|
|
Falls Risk Assessment: Quantitative or Qualitative?
|
Quantitative...I think
Measures: - physiological changes such as sensation, vision, muscle force/activity, neuromuscular |
|
|
What is the Biggest Indicator of Falls?
|
history of previous falls
|
|
|
Physiological Profile Assessment:
- What is it? - Validity Stats? - Ranges of Ratings? |
- it is a test used to determine fall risks factors
- predicts increased risk of falling with 75-79% accuracy - range: -2 (very low risk) to +4 (very high risk) |
|
|
PPA Components
|
- postural control
- reaction time - proprioception - lower limb strength - sensation - vision |
|
|
Effects of Balance Training on Diabetes Patients
|
- increased quadriceps strength
- decreased postural sway |
|
|
Spatio-temporal Variables
|
- stride time (s)
- stride rate = 1/time |
|
|
What is GAITRite?
|
- spatio-temporal analysis of locomotion
- pressure sensitive - reliable and valid |
|
|
What Information Does GAITRite Provide?
|
step time
cycle time step length single support double support toe in/toe out stride length and more... |
|
|
Stride Rate
|
= stride (length/rate)
|
|
|
Stride Length Measurements in Adults and Children
|
Adults: 1.5 m
Children: equal to their height |
|
|
Accelerometer Pads Are Attached to:
|
- head
- neck (C5-C6) - lower trunk - lower leg |
|
|
What is Motion Analysis?
|
- considered gold standard
- used to determine activity that is going on at joints |
