The subjects were evaluated with the case report form, the balance and fall risks, the Tinetti Gait and Balance Test (TGBT) and the 5-times Sit to Stand Test, while the gait speed was assessed by the Gait Speed Measurement Test (GSMT). The virtual reality group was trained with games selected from different categories such as balance and aerobic exercises with Nintendo Wii virtual reality device for 6 weeks, 1 session 30 min, 2 times a week. In the control group, no treatment was performed during this period and routine medical treatments were continued. In the first session, each Nintendo Wii components were introduced to each individual. The selected games and how they were played were taught to each individual by the physiotherapist and practically taught. The games were played with the help of physiotherapists in the first session so that individuals could transfer the correct weight on the Nintendo Wii balance board and to use the game console's control.

The sociodemographic characteristics of the subjects were evaluated with the case report form, the balance and fall risks, the Tinetti Gait and Balance Test (TGBT) and the 5-times Sit to Stand Test, while the gait speed was assessed by the Gait Speed Measurement Test (GSMT).the control group was reevaluated at the end of the 6th week after the initial evaluation. After the study was completed, training was given to the volunteers from the control group.

In the first session, each Nintendo Wii components were introduced to each individual. The selected games and how they were played were taught to each individual by the physiotherapist and practically taught. The games were played with the help of physiotherapists in the first session so that individuals could transfer the correct weight on the Nintendo Wii balance board and to use the game console's control. The patient was supported with verbal and physical feedback when the patient played incorrectly during the games in the next sessions. Games that require serious balance and coordination were considered as a difficult activity for the patient and were not used in this study. The difficulty of the games was set to the simplest level for each patient. As the patients were successful the games' difficulty level was upgraded. The difficulty of the games has been increased according to the classification determined by the Nintendo Wii device.

TGBT consists of balance and gait subheadings. For balance, there are 13 items, and 9 items for gait. Items are scored as 0 (abnormal), 1 (adaptive) and 2 (normal) for balance, 0 (abnormal), 1 (normal) for gait. The maximum balance score of the patient is 26 and the maximum gait score is 9. Total score (balance + walking) is 35 points.

5 times sit to stand test is a test that evaluates the functional strength of the lower extremity, balance and fall risk. In order to perform this test, a standard size chair with a stopwatch and a flat back is required. We said to the patient that "Please cross your arms to the other shoulder, and when I say start, sit and stand 5 times in the fastest and straightest way you can". I will measure your time with the stopwatch. The rank of the patients was told to them for sit and stand. In the elderly, if the duration of this period is more than 12 seconds indicated the risk of falling, if it is over 15 seconds, this is an indicator of the presence of a risk of repetitive drop

For GSMT, individuals were asked to walk at a speed they wanted on a flat surface of 14 m. Signs were placed on the 2nd and 12th meters of the test area to minimize the speed changes between walking start and walking finish, and to make a more objective measurement. The walking time at this 10-meter distance was measured with the stopwatch and the results were recorded in sec and the walking speed was determined

It was used to determine the cognitive state before the training. The Mini-Mental State Test was first published by Folstein et al. It consists of eleven items under 5 main headings: orientation, record memory, attention and calculation, recall and language, and the total score is evaluated over 30 points.
