The Effect of Dual Task Training With Virtual Reality on Upper Extremity Functions and Cognitive Functions in Stroke Patients

Purpose: To investigate the effect of upper extremity single and double task training using virtual reality on upper extremity functions, cognitive functions and dual task performance in stroke patients.

Materials and Methods: The study was planned on patients who applied to Erenkoy Physical Therapy and Rehabilitation Hospital and were diagnosed with hemiplegia by a specialist neurologist. Participants who met the inclusion criteria in the study will be divided into two groups as Group 1 = study group and group = 2 control groups by computerized randomization method. For the evaluation of upper extremity functions of the participants whose socio-demographic characteristics were recorded; Fugl Mayer Upper Extremity Assessment Scale, Box and Blocks Test (BBT), Stroop Test and Montreal Cognitive Assessment Scale (MOCA) will be used to evaluate cognitive functions. The Barthel index of daily living activities of the patients and the Stroke-Specific Quality of Life Assessment Scale will be used to evaluate the health-related quality of life. Evaluation of double-task performance will be evaluated by the Box and Blocks Test (BBT) and a cognitive task added to the Xbox 360 Kinect game apps. Participants will be evaluated 4 times before the treatment, after the treatment and at the 1st month and 3rd month after the treatment in order to see the sustainability of the effect of the rehabilitation program.

Patients in both groups will receive a conventional upper extremity rehabilitation program (neurophysiological methods, joint range of motion exercises, strengthening exercises, occupational therapy) and 30 minutes of virtual reality training for 6 weeks, 5 days a week, for 45 minutes daily. Participants in the study group will be given double-task training in addition to stroke rehabilitation and virtual reality training. Dual task training will be performed with the addition of cognitive tasks in addition to virtual reality training.

Cognitive Tasks;

1. Attention-oriented, e.g. Counting numbers: Counting numbers backwards three by three from the participant rhythmically,
2. For memory, e.g. describing activities of daily living: Describing an event from the participant in detail,
3. For executive functions, e.g. Verbal communication: It will be planned in the form of giving the participant a letter from the alphabet and asking for words in certain categories such as plants, animals and countries. As progress is made, the difficulty of the missions will increase.
