WIMI Hologram Academy: Virtual Reality Technology Provides An Immersive Recovery Experience
May 19 2022 - 8:30AM
WIMI Hologram Academy, working in partnership with the Holographic
Science Innovation Center, has written a new technical article
describing their exploration of virtual reality technology in the
field of immersive recovery experience. This article follows
below:
For many stroke patients, if timely and
effective rehabilitation training and treatment can be obtained,
the patients' limb movement can be restored to realize their
self-care ability. However, the traditional rehabilitation training
therapy needs to match auxiliary rehabilitation training
institutions and medical staff guidance, and different
rehabilitation training conditions need to match the auxiliary
rehabilitation medical equipment, and medical staff skills and
clinical experience requirements are very high, due to the shortage
of medical staff and rehabilitation patients, cause individual
patients rehabilitation training time is limited, which lead to
patients miss the best rehabilitation training time. Because of the
current supply and demand imbalance between rehabilitation doctors
and patients, new rehabilitation treatment has been introduced into
the rehabilitation medical field, with the development of computer
technology, and the gradual development of virtual reality has been
rapidly caused the medical experts and scholars to attach great
importance to and gradually apply virtual reality technology in
rehabilitation training, so virtual reality rehabilitation
technology arises at the historic moment.
Virtual reality technology is widely used in
education, entertainment, medical care, and other fields due to its
interaction, immersion, and conception. In the medical field,
virtual reality can provide patients with an immersive
rehabilitation experience, and human-computer interaction
technology can greatly improve the rehabilitation efficacy of
patients. Scientists who are from WIMI Hologram Academy of WIMI
Hologram Cloud Inc.(NASDAQ: WIMI), discussed the virtual reality
rehabilitation technology with the limb movement function
rehabilitation training of stroke patients as an example.
Virtual reality technology is constantly applied
in the rehabilitation training of patients, on the one hand, it
reduces the traditional assisted exercise treatment mainly based on
rehabilitation doctors while avoiding the irregular problems; on
the other hand, it drives the consciousness of active
rehabilitation training to some extent, enabling rehabilitation
training in a comfortable environment. Virtual reality technology
is constantly applied in rehabilitation training, also mainly
reflected in its can provide other based on auxiliary mechanical
training can not provide perception and enjoyment, can make the
patient in the process of rehabilitation training appear more
natural, have a sense of achievement, virtual reality technology
into rehabilitation treatment will be an important direction in the
field of future rehabilitation.
Clinical studies have shown that, through timely
and active rehabilitation training, most stroke patients can
recover their simple limb movement ability, and even recover. The
traditional recovery treatment of stroke is based on reflex or
graded motor control, which mainly relies on rehabilitation doctors
to manually assist patient rehabilitation training. The progress
and formulation of rehabilitation training cannot be effectively
guaranteed, which often makes patients miss the more serious
consequences due to the best treatment period. Regarding the
individual variability of convalescent stroke patients,
Electroencephalography (EEG) and Electromyography (sEMG) signals
can reflect the motor functional status of different individuals in
real-time, Patient physiological status was obtained by analyzing
B- EMG signals, And as feedback adaptive adjust the virtual scene
is difficult, Not only can improve the patients' initiative and
self-confidence in rehabilitation training, And to avoid secondary
injuries caused by training under fatigue, Ensure the safety of
rehabilitation training, Make the rehabilitation training more
intelligent and humanized, promote the clinical and practical
process of virtual reality technology, To alleviate the shortage of
rehabilitation doctors and the lack of assisted training of
rehabilitation robots, It has important economic and social
value.
The traditional recovery treatment of stroke is
based on classification or reflex motion control, mainly relying on
rehabilitation doctors to manually assist patient rehabilitation
training, rehabilitation training cannot be effectively guaranteed,
thus affecting the rehabilitation effect.
Common rehabilitation sports function training
based on virtual reality technology mainly includes the
corresponding game scene in the process of rehabilitation training,
so that patients have some fun in the rehabilitation training
process, but it is still difficult to mobilize patients' active
participation consciousness and self-confidence. At the same time,
due to the lack of evaluation strategy for the patients'
physiological state, patients have fatigue in the rehabilitation
process, prone to accidents and secondary injuries, which limits
the clinical promotion and application of virtual reality
technology.
The system workflow is as follows:
(1)Stroke patients combined with rehabilitation
training with a virtual rehabilitation system, synchronously
collect EEG & EMG signals from stroke patients and wirelessly
sent them to the PC end.
(2) The PC terminal obtains EEG & EMG
signals and carries out the signal preprocessing in the early
stage. On the one hand, the feature vector based on the sEMG motion
pattern is extracted to realize the effective characterization of
the movement pattern of stroke patients; On the other hand, EMG
fatigue index and EEG fatigue index were extracted as the
characteristic vectors of exercise fatigue evaluation, to
effectively depict the fatigue degree of stroke patients.
(3) Send the motion mode feature vector to the
intelligent classifier 1 for motion mode classification, and
control the virtual rehabilitation training scene according to the
classification results.
(4) The s EMG fatigue index and EEG fatigue
index are sent to the intelligent classifier 2 for fatigue
classification and adjust the difficulty of the virtual
rehabilitation training scene according to the classification
results. The system overcomes the shortcomings of current
rehabilitation training, not only realizing human-computer
interaction based on virtual scene to get rid of physical
rehabilitation training, reduce or enhance the rehabilitation
training intensity and avoid secondary damage caused by improper
training.
