Anatomical Movement[edit | edit source]
Thumb metacarpophalangeal (MCP) joint flexion and extension
Testing Positions[edit | edit source]
Thumb Metacarpophalangeal Joint Flexion[edit | edit source]
Starting Position[edit | edit source]
Patient is seated with arm rested on a table and elbow flexed. The forearm is positioned in the mid-position and the wrist is slightly positioned in extension. The MCP joint being measured is at 0° of extension.[1]
Ending Position[edit | edit source]
The thumb MCP joint is flexed to the limit of motion.[1]
Stabilization[edit | edit source]
The clinician stabilizes the metacarpal.[1]
Thumb Metacarpophalangeal Joint Extension[edit | edit source]
Starting Position[edit | edit source]
Patient is seated with arm rested on a table and elbow flexed. The forearm is positioned in the mid-position and the wrist is slightly positioned in extension. The MCP joint being measured is at 0° of flexion.[1]
Ending Position[edit | edit source]
The thumb MCP joint is extended to the limit of motion.[1]
Stabilization[edit | edit source]
The clinician stabilizes the metacarpal.
- Clinical Tip: The interphalangeal (IP )joint is allowed to flex/extend during flexion and extension measurements respectively.[1]
Goniometer Placement[edit | edit source]
| AXIS LOCATION[1] | STATIONARY ARM[1] | MOVEMENT ARM[1] |
|---|---|---|
| Over the dorsal aspect of the MCP joint | Parallel to the longitudinal axis of the shaft of the metacarpal | Parallel to the longitudinal axis of the proximal phalanx |
Expected Findings[edit | edit source]
Thumb MCP Joint Flexion[edit | edit source]
0-55°[2]
Thumb MCP Joint Extension[edit | edit source]
0-10°(Hyperflexion)[2]
