This sounds great. Where is the protocol for building it AND the protocol for recovery of your hand? Your hospital should have it available in one month. If not, have the board of directors fired.

Abstract
Background:Stroke survivors can be affected by motor deficits in the hand.
Robotic equipment associated with brain-machine interfaces (BMI) may aid the
motor rehabilitation of these patients. BMIs involving orthotic control by motor
imagery practices have been successful in restoring stroke patients’ movements.
However, there is still little acceptance of the robotic devices available, either by
patients and clinicians, mainly because of the high costs involved. Motivated by
this context, the present work aims to design and construct the Hand
Exoskeleton for Rehabilitation Objectives (HERO) to recover extension and
flexion movements of the fingers.

Exoskeleton for Rehabilitation Objectives (HERO) to recover extension and
flexion movements of the fingers.
Methods:
A 3D printing technique in association with textiles was used to
produce a lightweight and wearable device. 3D-printed actuators have also been
designed to reduce equipment costs. The actuator transforms the torque of DC
motors into linear force transmitted by Bowden cables to move the fingers
passively. The exoskeleton was controlled by neuroelectric signal —
electroencephalography (EEG). Concept tests were performed to evaluate control
performance. A healthy volunteer was submitted to a training block with the
exoskeleton, according to the Graz-BCI protocol. Ergonomy was evaluated with a
2D tracking software.

Results:
The outcome of the applied manufacturing technique was aesthetically
pleasing. HERO’s glove can be compared to ordinary clothing. The weight over
the hand was around 102 g. The volunteer(Was this a stroke survivor?) was able to control the exoskeleton
with 91.5% accuracy.
Conclusions:

with 91.5% accuracy.
Conclusions:
HERO’s project resulted in a lightweight, simple, portable,
ergonomic, and low-cost device. Its use is not restricted to a clinical setting.
Thus, users will be able to execute motor training with the HERO at hospitals,
rehabilitation clinics, and home, increasing the rehabilitation intervention time.
This may favor motor rehabilitation and improve the life quality of stroke
survivors.
