Project Orekhov has conducted an in-depth literature review to evaluate the state of the field. This has allowed the team to work diligently towards a working solution ascertained from the failures and success of other devices. Project Orekhov identified two primary categories of devices that provide assistance to the hand and upper limb: therapeutic devices, and engineering (research) devices. A brief explanation of each type of device is provided below.
Bridging the gap between engineering devices and therapeutic devices

|---|---|
| Light and Portable | Little or no dynamic assistance |
| Affordable | Little to no research potential |
| Easily adjustable | One device adresses one function |
| Low maintenance | Relies on straps, buckles, and fasteners |
| Verified clinical benefit |
| Benefits | Shortcomings |
|---|---|
| Dynamic assistance | Bulky and Heavy |
| Precise controllability | Expensive |
| Multiple degrees of freedom | Often uncomfortable |
| Provides direct feedback | Clinical benefit is rarely verified |
| High maintenance |
