Very little motion occurs at the 2nd and 3rd CMC joints as compared to the 4th and 5th CMC joints. The limited ROM of the 2nd and 3rd CMC joints provide stability for grasp functions of the muscles of the hand
More motion occurs at the 2nd and 3rd CMC joints as compared to the 4th and 5th CMC joints. The increased ROM of the 2nd and 3rd CMC joints provides mobility for grasp functions of the muscles of the hand
Very little motion occurs at the 4th and 5th CMC joints as compared to the 4th and 5th CMC joints. The limited ROM of the 4th and 5th joints provide stability for grasp functions of the mucles of the hand.
The same motion occurs at the 4th and 5th CMC joints as compared to the 2nd and 3rd CMC joints. The equality ROM of all the CMC joints provides stability and mobility for grasp functions of the muscles of the hand

Joint ROM of MCP joint decreases from radial side of the hand to ulnar side of the hand. This decrease in ROM helps the ulnar side of the hand shape itself around objects during grasp and adds power to grasp
Joint ROM of MCP joint stays the same from radial side of the hand to ulnar side of the hand. This allows the ROM of the MCP joints to add precision control to grasp
Joint ROM and MCP joint increases from ulnar side of the hand to radial side of the hand. This increase in ROM helps the radial side of the hand shape itself around objects during grasp and adds precision to grasp
Joint ROM and MCP joint increases from radial side of the hand to ulnar side of the hand. This increase in ROM helps the ulnar side of the hand to shape itself around objects during grasp and adds power to grasp
