studies to assess neurocognitive rehabilitation pro-
grams efficacy. The studies present a considerable
heterogeneity of the instruments and methods used,
even for the same assessment purpose; a lack of con-
sensus regarding assessment protocol is well visible.
A systematic review in (Resch et al., 2018) exam-
ines studies investigating cognitive rehabilitation in-
terventions for children with ABI, also focusing on
identifying effective (computerized) drill-based exer-
cises. Authors conclude (preliminarily, due to small
sizes and heterogeneity of included studies) that avail-
able evidence suggests that multi-component rehabil-
itation, including drill-based training, is most promis-
ing and can lead to improvements in children’s cogni-
tive and psychosocial functioning ABI.
A clinical review dealing with neurorehabilita-
tion of traumatic brain injuries (TBIs) is presented
in (Oberholzer and M
¨
uri, 2019). The authors point
out specific characteristics of TBI individuals com-
pared to individuals with ABIs. They address ques-
tions on timing and existing evidence for various re-
habilitation programmes and their impact on the out-
comes in TBI rehabilitation. They also state that
there are currently no international guidelines regard-
ing treatment in the early rehabilitation phase for pa-
tients with severe TBI and that only a few studies
have investigated the effect of integrating rehabilita-
tion into acute TBI care.
A literature review of immersive virtual reality in
TBI rehabilitation is provided in (Aida et al., 2018)
concluding that ”while the current literature gener-
ally offers support for the use of VR in TBI recov-
ery, there is a paucity of strong evidence to support its
widespread use”.
A qualitative study aimed to explore the needs of
individuals with TBIs and their loved ones (Lefebvre
and Levert, 2012) point out that health care profes-
sionals should adopt a personalized approach to re-
spond to needs related to the evolution of informa-
tion, support, and relationships among them, individ-
uals with TBIs and their loved ones.
A systematic review (Coxe et al., 2020) deal-
ing with telebehavioral interventions for family care-
givers of individuals with TBI concludes that care-
givers generally express positive outcomes related to
telebehavioral interventions, but low diversity of sam-
ples prevents generalizing these outcomes.
A critical review of the literature (Fetta et al.,
2017) dealing with the efficacy of computer-based
cognitive rehabilitation interventions on cognitive
performance after mild TBI and ABI concludes that
computer-based interventions seem promising when
improving working memory in individuals with ABI.
However, there is no evidence that currently available
interventions are specific to mild TBI.
To summarize the state-of-the-art section, we can
argue that many studies describe ABI/TBI rehabilita-
tion’s success. On the other hand, only a small part
of the studies was carried out so that the success of
the rehabilitation, or rather the rehabilitation proce-
dures used, was proven. This can also be stated in the
case of computer-based rehabilitation. All in all, the
evidence that targeted rehabilitation procedures lead
to significantly better results than any rehabilitation,
even if based on everyday human activities, is not
convincing.
Finally, we can modestly state that various stim-
uli that motivate ABI people to be active and improve
their abilities and skills have a rehabilitative character.
Then, a computer-based system providing tasks tar-
geted to improve various skills and abilities can help
ABI people, their families, and therapists in the long
term.
3 BrainIn SYSTEM
BrainIn is an online software system (web applica-
tion) for the neurorehabilitation of patients with ABI.
It is designed for patients in institutional and home
care, their families, and therapists and enables the
computerized definition, execution, and basic evalua-
tion of personalized neurorehabilitation tasks of vary-
ing degrees of difficulty for each patient. The ther-
apist defines the sets of personalized neurorehabilita-
tion tasks, and the patient then performs them with the
help of the therapist, the family, or completely alone.
The main advantage of the BrainIn system is the pos-
sibility of personalization of the tasks by the therapist,
the creation of exercises of different difficulty lev-
els, the organization of activities in packages, and the
readiness of the system for partially automated evalu-
ation of the patient’s results and the subsequent use of
machine learning methods to make recommendations
for personalized therapies.
The BrainIn system is based on task templates
with input variables for adjusting each task for an in-
dividual patient. These input variables must be set
before execution. Their setting occurs in the task that
runs the program. These tasks are easily editable, and
it is easy to create a similar version (for example, with
a different number of rounds, other pictures, ques-
tions, etc.). The exercise for each patient typically
forms a package consisting of multiple tasks.
We have introduced the terms template, task, and
package.
• A template is both the program itself and a web
form defining input and output variables. Input
