Three Points to Watch

• Arch - the arc created while your hand is in mid-range of motion
• Alignment - the "straightness" from your elbow to your hand through the wrist
• Rotation - movement of the hand like opening a door; a twist

Example

Example Explained

Arch usually refers to the right hand as seen in the above left example.

The right example shows that the arch exists also in the left hand because it is also in the mid-range of motion.

To clarify, the wrist, just like the fingers, can be in mid-range of motion (relaxed in the middle of flexion and extension).

Example

Example Explained

Alignment is easy to see if you can imagine a straight line being drawn from the inside arm up through the knuckle of the "i" finger of the right and the "1" finger of the left hands.

Remember these are ideal guidelines and the most efficient. However, in certain and few circumstances they can be slightly altered. Afterwards, the hands should return to their states of ideal movement

Example

Example Explained

Rotation applies mainly to the right hand.

In later chapters, this rotation will become more meaningful. For now, remember the term associated with the right hand.
