Study Notes
Goniometer Alignment for Elbow Flexion
- Stationary arm: Lateral midline of humerus towards acromion process
- Axis: Lateral epicondyle of humerus
- Moving arm: Lateral midline of radius towards radial styloid process
Elbow Extension
- Normal ROM = 0 to 5 degrees
- Patient position: Supine with upper extremity in anatomical position, elbow extended as far as possible, folded towel under distal humerus, proximal to humeral condyles
Reliability of Assessment Tools
- Test-retest reliability indicates how repeatable scores are across time
- Alternate or parallel form reliability determines the consistency of scores on different forms of a test
- Inter-rater reliability indicates the consistency of scores when assessed by different raters
Joint Hypermobility & Hypomobility
- Hypermobility occurs from laxity, allowing for greater than normal movement
- Hypomobility is joint tightness or decreased ROM
Uses of Goniometric Measurements
- To evaluate the joint's range of motion
- To determine the effectiveness of treatment programs
- To reassess a patient's status after treatment
- To develop patient motivation and enthusiasm for treatments
Factors Affecting Range of Motion
- Age: Generally, younger people have greater ROM
- Sex: Women tend to have greater ranges than men
- Joint structure: Genetics and posture can influence hypermobility or hypomobility
- Body type: Can influence joint activity, as can tendon and ligament flexibility
- Muscle bulk: Soft tissues can limit motion
Considerations for Goniometric Measurement
- Patient position: The selected position must allow for the intended movement
- Stabilization: Ensure adequate stabilization of the proximal bony segment to prevent substitution motion
- Palpating bony landmarks: Essential for accurate alignment of the measurement device
Goniometry Procedure
- Determine the type of measurement (AROM or PROM)
- Explain the purpose of the procedure
- Position the patient according to measurement requirements
- Stabilize the proximal joint segment
- Instruct the patient on the motion to be measured
- Determine the end-feel of the motion
- Return the joint to the starting position
- Palpate bony landmarks for alignment
- Align the measurement device
- Read the scale on the device
- Have the patient actively or passively move through ROM
- Re-palpate bony landmarks and adjust alignment as necessary
- Read the scale and note the reading
- Record patient ROM
Glenohumeral Joint
- Ball-and-socket joint
- Formed by the articulation of the humeral head with the glenoid fossa of the scapula
- Relatively unstable due to shallowness of the glenoid fossa
- Allows for wide range of motion
- Three degrees of freedom: flexion/extension, abduction/adduction, and medial/lateral rotation
- Normal end-feel for all motions is firm
Limitations in the Glenohumeral Joint
- Elevation (flexion or abduction) is limited by the inferior glenohumeral ligament and the inferior joint capsule
- Extension is restricted by the superior and middle glenohumeral ligaments
