The Effect of Motor Image Training on Balance Performance in Geriatric Individuals

Official title

Investigation of the Effects of Motor Imagery Training Given With Action Observation on Balance Performance in Geriatric Individuals

Overview

The goal of this study \[type of study: clinical trial\] is to was planned to investigate the effect of motor imagery training given to geriatric individuals with action observation on their balance performance and to compare these two methods. The main questions it aims to answer are: 1. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving static balance than virtual reality-based balance training given alone? 2. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving dynamic balance than virtual reality-based balance training given alone? 3. Is virtual reality-based balance training given together with motor imagery for six weeks in geriatric individuals more effective in increasing balance confidence than virtual reality-based balance training given alone? 46 geriatric individuals will be randomized into 2 groups. Along with action observation, motor imagery training and virtual reality-based balance training will be given to the study group. On the other hand, only virtual reality-based balance training will be given to the control group. All assessments will be repeated before and after the trainings. The trainings will be applied 2 days a week for 6 weeks. Each training session; 25 minutes for the control group and 45 minutes for the study group.

Detailed description

Muscle strength, proprioception, joint mobility, vestibular losses and vision losses may occur with the aging process. These losses may lead to a decrease in the ability of geriatric individuals to adapt to environmental factors. This loss of harmony may cause balance disorders in individuals by affecting static and dynamic postural control performance. Looking at the literature, balance trainings, functional exercises, flexibility, muscle strength and endurance trainings, Tai Chi, Qigong-like yoga exercises, dance, walking programs, motor imagery training given with traditional methods or virtual reality systems for the purpose of improving balance and postural control. There are studies showing the effectiveness of many methods in geriatric individuals. However, no study has been found that examines and compares the effects of virtual reality-based balance training and motor imagery training combined with action observation in addition to virtual reality-based balance training in geriatric individuals. For this reason, this study was planned to investigate the effect of motor imagery training given to geriatric individuals with action observation on their balance performance and to compare these two methods.

The study, which was designed as a prospective, randomized controlled, cross-sectional, single-blind (evaluator), will include 46 geriatric individuals aged 60 and over. The study will be initiated with individuals who meet the inclusion/exclusion criteria of the study. 46 geriatric individuals will be randomized into 2 groups. The study group (23 cases) will be given motor imagery training and virtual reality-based balance training along with action observation. Only virtual reality-based balance training will be given to the control group (23 cases). First of all, age, gender, height, body weight, upper extremity dominant side, lower extremity dominant side, body mass index, smoking history, alcohol consumption, occupation, employment status, chronic diseases, regularly used drugs, history of falling and staggering, history and pedigree information, independence in daily living activities, ability to walk 10 meters without any walking aid will be recorded. In the first evaluation before the training, the measurement of the electrical potential changes known as muscle motor unit action potentials of the subjects during the postural swings will be evaluated with the electromyography biofeedback device. Static and dynamic balance assessments will be evaluated with computerized kinesthetic balance device, Berg Balance Scale and 10 Meter Walk Test. Three-axis (x, y and z) evaluation of body oscillations will be made with an android-based smartphone application. Motor imagery skills will be evaluated with the Movement Imagination Questionnaire-3 (HIA-3) and the mental stopwatch test. All assessments will be repeated before and after the training (6 weeks later) by a researcher blinded to the training. As a training protocol, individuals in both groups will be given static and dynamic balance training with a balance platform game console (20 minutes) containing interactive video games based virtual reality for a total of 6 weeks. Before the balance training, a 5-minute relaxation training will be given to both groups. In addition to the virtual reality-based balance and relaxation training, the study group will be given motor imagery training (10 min + 10 min) with action observation before the balance training. The trainings will be applied 2 days a week for 6 weeks. Each training session; 25 min for the control group. (Relaxation training (5 min) + virtual reality-based balance training (20 min), 45 min for the study group. (Relaxation training (5 min) + motor imagery training (20 min) + virtual reality-based balance training (20 min) with action observation. All questionnaires, scales, tests and devices used in the initial evaluations will be repeated for the individuals in both groups at the end of the 6-week training. The effectiveness of the trainings will be compared with appropriate statistical methods within and between groups and discussed in the light of the literature.

Interventions

• Other Balance Training
  Participants will be given static and dynamic balance training with a balance platform game console (20 minutes) containing interactive video games based virtual reality for a total of 6 weeks.
• Other Motor İmagery Training
  For motor imagery training, two visualization scenarios will be created: anterior and posterior motor imagery. One of the visualization scenarios appropriate to each individual's needs will be used. Participants will be asked to perform kinesthetic or visual motor imagery in accordance with the scenario they listened to (10 minutes).
• Other Action Observation Training
  Action observation training will be done using video modeling method. The video content will include Nintendo Wii games in which the games that the person will play in that session are played by someone else and successful scores are achieved (10 minutes).
