Hand-forearm dimension | Definitions |
---|---|
1) Hand length | • The distance from the base of the hand to the top of the middle finger measured along the long axis of the hand |
2) Palm length | • The distance from the base of the palm to the base of the middle finger (at the palmar surface). |
3) Hand breadth across thumb | • The breadth of the hand measured at the level of the distal end of the first metacarpal of the thumb. |
4) Hand breadth metacarpal | • The breadth of the hand as measured across the distal ends of the metacarpal bones. |
5) Hand circumference | • The close measurement that follows a hand contour at the maximum palm level. |
6) Fist length | • Length of the hand grip in the same line of the long axis of the hand from the base of the palm to the tip of the fist, wherever found. |
7) Fist circumference | • Maximum circumference of the fist, wherever found, encompassing the knuckles of the middle finger and the thumb. |
8) Maximum internal grip diameter | • The measured by sliding the hand down a graduated cone until the tips of the thumb and the middle finger remain touched to each other |
9) Thumb length (digit 1) | • The distance from the tip of the thumb to its proximal crease. |
10) Index finger length (digit 2) | • The distance from the tip of the index finger to its proximal crease. |
11) Middle finger length (digit 3) | • The distance from the tip of the middle finger to its proximal crease. |
12) Ring finger length (digit 4) | • The distance from the tip of the ring finger to its proximal crease. |
13) Pinky finger length (digit 5) | • The distance from the tip of the pinky finger to its proximal crease. |
14) Hand depth | • The maximum depth from the volar side of the thenar pad to the dorsal surface of the hand (Hand is extended with palm facing down; fingers are close together with the thumb held against the side of the hand) |
15) Wrist circumference | • This dimension is measured using a tape measure, which is wrapped around the bony part of wrist, snug but not tight. |
16) Forearm Length | • The distance between radial styloid process and lateral humeral epicondyle. |
17) Forearm Circumference | • The circumference of the forearm at the point of maximum prominence, slightly distal to the elbow joint. |
