Benefits of technology

[0013] A second set of adjustments is provided at the trigger by changing the spring that is used to push the trigger back to the starting point FIG. 2. This embodiment of the tool allows the operator to remove the trigger and replace the standard spring with one with a higher or lower spring constant. The trigger spring is instrumental in the design as the spring can be the dominant force at both low and high loads depending on the settings and adjustments.

[0017] Being able to adjusting the depth of the trigger provides A third additional feature FIG. 3e. Since work is equal to force times distance, changing the distance changes the work done by the user. This feature also helps to improve the ergonomics since hand sizes differ and thus the overall position where the fingers would curl the trigger would differ.

[0021] By working with variants of the four settings, a versatile and ergonomic tool is available for a vast population from rehabilitation to world class athlete. The discussion has shown that the hand, fingers, wrist and forearm can all be strengthened using this tool. The versatility, ease of use, and upgradeability / repairability all make the device an improvement of current product on the market.

Problems solved by technology

Some forms of equipment do not allow adjustments or have very minimal adjustment capability.

For instance, a broken wrist cannot begin with some of the tool that that require up to 5 to 10 pounds of force to pull the levers.
