Goniometry Flashcards
What does a goniometer consist of
Moving arm
Body
Stationary arm
Hypermobility
Joints have an unusually large range of motion
Hypomobility
Joints are too tight and there is a decreased range of motion
Ways of measuring the range
Using a goniometer
Measuring the distance between points
Visual estimation in degrees or as a fraction of the total range
Tracing limb on a piece of paper
Procedures of Goniometry
Positioning
Stabilization
Goniometer alignment
End feels
Soft - knee flexion (soft tissue approximation)
Firm - Hip flexion (knee straight - Muscular stretch capsular and ligaments)
Hard - elbow extension
Empty - no mechanical limitations to the end of range but client experiences excessive pain
Factors affecting joint ROM
Pathological factors - diseases
Neurological factors - stroke and accidents
Biological - difference between male and females
Why do we measure joint ROM
For progress and regress
Baseline readings
Motivation
Principles for measuring joint ROM
- Motions of a joint are measured from zero starting position
- Anatomical position of an extremity is the accepted zero position
- Movement examined should be compared to the opposite extremity
- Distinguish between active and passive range of motion
- AROM - unassisted voluntary movement
- PROM - movement attained by the examiner without the assistant of the subject
How are movements done
Actively
Active assisted
Passively
Documenting the range
Number of degrees of movement from the zero position indicates the range of motion, eg
Knee flexion : 0 - 135 ( full flextion and extension)
Knee flexion : 20 - 135 ( limitations of extention)
