Q
Thumb CMC Abduction Goniometer Alignment
A
- Center fulcrum of the goniometer over the lateral aspect of the scaphoid or radial styloid process, so that the proximal and distal arms of the goniometer can be properly positioned over the long axes of the first and second metacarpals.
- Align proximal arm with the lateral midline of the second (index) metacarpal, using the center of the second MCP joint for reference.
- Align distal arm with the dorsal midline of the first (thumb) metacarpal, using the center of the first MCP joint for reference.
11
Q
Thumb CMC Extension Goniometer Alignment
A
- Center fulcrum of the goniometer over the palmar aspect of the first CMC joint.
- Align proximal arm with the ventral midline of the radius, using the ventral surface of the radial head and the radial styloid process for reference.
- Align distal arm with the ventral midline of the first metacarpal.
12
Q
Thumb CMC Flexion Goniometer Alignment
A
- Center fulcrum of the goniometer over the palmar aspect of the first CMC joint.
- Align proximal arm with the ventral midline of the radius using the ventral surface of the radial head and radial styloid process for reference.
- Align distal arm with the ventral midline of the first metacarpal.
13
Q
Thumb MCP Flexion Goniometer Alignment
A
- Center fulcrum of the goniometer over the dorsal aspect of the MCP joint.
- Align proximal arm over the dorsal midline of the metacarpal.
- Align distal arm with the dorsal midline of the proximal phalanx.
14
Q
Thumb MCP Extension Goniometer Alignment
A
- Center fulcrum of the goniometer over the dorsal aspect of the MCP joint.
- Align proximal arm over the dorsal midline of the metacarpal.
- Align distal arm with the dorsal midline of the proximal phalanx.
15
Q
Thumb IP Flexion Goniometer Alignment
A
- Center fulcrum of the goniometer over the dorsal surface of the IP joint.
- Align proximal arm with the dorsal midline of the proximal phalanx.
- Align distal arm with the dorsal midline of the distal phalanx.
