Methods: Sixteen patients within 12 weeks after stroke and determined gait as categorized with a Functional Ambulation Category score of 3 or 2 were contained in this pilot study.

Participants received eight 30-min sessions of Virtual Reality For Training during four weeks as part of their normal inpatient rehabilitation program. Feasibility was evaluated using compliance with all the practice, adverse events, experiences of the participants along with the physiotherapists; and

effectiveness with all the Berg Balance Scale, the center of pressure pace, Functional Ambulation Category and 10-meter walking test. Results: Participants positively assessed the intervention and enjoyed the training sessions. Additionally, physiotherapists observed the training as possible and

beneficial for enhancing balance or gait. Compliance with all the practice was 88% and no severe adverse events happened. The Berg Balance Scale, the anterior-posterior center of pressure velocity, Functional Ambulation Category, and 10-meter walking evaluation revealed significant improvement after four weeks of training Conclusion:

This study demonstrates that Virtual Reality in patients early after stroke is feasible and might be effective in improving balance and/or gait ability.

Balance and gait retrieval are believed to be crucial aspects of stroke rehabilitation [1-3]. Also, cognitive participation, functional relevance and the presence of opinions improve learning [5]. In present physiotherapy or occupational therapy, it is difficult to meet all of these above-mentioned coaching attributes as therapy may be dull and resource-intensive [6-9].

In addition, the frequency and intensity of current treatments have been suggested as inadequate to reach maximum recovery at the early phase of rehabilitation [8,10]. There's a need for engaging, inspiring and diverse therapy that achieves maximal recovery [11]. In the last few years, Augmented Reality Companies has been introduced in the subject of balance and gait rehabilitation after stroke [12]. Since Virtual Reality Companies is

characterized by individualized, high-intensity training in many different virtual environments with a high amount of real-time feedback [13-15] it might be valuable in stroke rehabilitation. This is supported by recent studies [12,15-18]. However, almost all research on the effect of VR on balance and/or gait capacity was running at the chronic stage after brain injury

[9,12,16,17,19-23]. Because of the potential relevant qualities of VR for motor learning and neuroplasticity [14], VR might be of even more added value during the earlier rehabilitation stage. On the other hand, the results of the studies cannot be generalized to the entire population of patients with stroke since comprised participants had a relatively high functional level regarding balance and gait at the start of the VR intervention.

A scarcity of studies including patients with lower functional status after stroke might be caused by the concept that the feasibility of using advanced VR technology might be restricted due to visual, cognitive or endurance impairments. These impairments are more often present in impaired patients early after stroke [27-29].

Due to the expected promising consequences of VR training to the healing of balance and gait in patients who have low functional level early after stroke, it is very important to inquire into the feasibility of the innovative type of training and also to ascertain whether the above-mentioned impairments interfere with the use of virtual reality for training early after stroke.

Patients with stroke who have been after an inpatient rehabilitation program with a treatment goal to improve balance and/or gait. Inclusion criteria consisted of hemiplegia resulting from a stroke, a time because stroke of less than 12 weeks, a Berg Balance Scale (BBS) score of 20, i.e. the minimal degree of balance deemed safe for balance interventions [30], and

a Functional Ambulation Category (FAC) score of 3 or 2 out of 5 [31]. All participants provided written permission to use data obtained during the rehabilitation program for study, and anonymity was ensured. The study procedures follow the principles of the Declaration of Helsinki. The GRAIL includes a dual-belt treadmill with force system, a motion-capture system (Vicon, Oxford, UK) and speed-matched virtual surroundings projected onto a 180° semi-cylindrical display

The VR Companies for training program consisted of 2 30-min sessions of exercises around the GRAIL a week for four months. Participants wore a safety harness which has been connected to an overhead suspension system but did not offer weight support. A predefined routine of
VR applications was used during the practice sessions of this four-week intervention.

This predefined protocol has been innovative starting with inactive balance exercises focussing on altering weight, followed by coaching lively balance and, if possible, coaching gait ability. Each application could be individualized to the individual's skill concerning difficulty, such as by adjusting duration, speed, the number of simultaneous activities and the amount of real-time visual, sensory or sensory feedback throughout the exercises. A physiotherapist, who is certified for working with the GRAIL, determined the development of their training sessions.
The physiotherapist regulated the degree of the exercises,

judged if a brand new and more difficult application could be used and guaranteed that security and quality of movement were preserved during the practice. Patients were asked about their experiences in the virtual training environment, the existence of potential side effects and their view on the plan and effects of the VR intervention. These interviews were conducted after the final training session. The questions about the

patients' experiences in the virtual surroundings comprised understanding and sense of presence in the virtual environment and were partially translated and adapted from the ITC-Sence of Presence Inventory poll of Lessiter et al. [33]. The statements that were covered in the interviews in the arbitrary sequence are exhibited in Tables 1 and 2.
