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
