  • The aim of this study was to evaluate the effects of mental practice to improve on gait and quality of life in stroke patients. Participants were randomly allocated to two groups: experimental(n=10) and control (n=10). Both groups received neural development treatment training for 6 sessions 1 hour per week during 6 weeks. Experimental group practiced additional mental practice for 3 session 10 minutes per week 6 weeks. Results were evaluated by spatial-temporal parameter, 10m walk test, and quality of life. There were significantly increased by mental practice in outcomes of the gait performance from the gait velocity, cadence, double support, single support, 10m walk test. There were significantly increased by mental practice in outcomes of stroke impact scale from the strength, social participants, and stroke recovery. In conclusion, the mental practice improves gait performance and quality of life in stroke patients. The results suggest that mental practice training is feasible and suitable to stroke patients.

  • Objective : The aim of this study is to prove the effects of mental practice in balance ability of elderly population, and to investigate the possibility of application as an effective intervention method for fall prevention. Methods : This study provided mental practice to 3 subjects over 65 years old who have experienced fall, but do not have cognitive dysfunctions and independent in gait without any use of assistive devices from July to October, 2013. Within the individual case study, 4 sessions of initial baseline process (A), 5 sessions of mental practice (B), 4 sessions of re-initial baseline process (A') were proceeded using ABA design. Independent variable used mental practice for enhancing balance ability and fall efficacy in elderly population, and dependent variable were Berg Balance Scale (BBS) to find out the change in overall balance ability, Fall Efficacy Scale (FES) to see the change in fall efficacy, One-Leg Standing test(OLS), and Timed Up and Go Test (TUG) to determine the changes in both static and dynamic balance. Analysis of the results were provided via mean value and graph. Results : After the application of mental practice method, all of the subjects have shown increase in fall efficacy baseline values, and in addition, overall balance ability and both static and dynamic balances either increased or maintained. Conclusion : This study demonstrated that mental practice has positive effects on fall efficacy improvement and maintenance in elderly, thereby suggesting mental practice for fall prevention in elderly populations.

  • The purpose of the research was to examine the effect of field of view on egocentric distance perception in the real and virtual environment. The replica that mimicked the real environment condition was used to create the virtual environment condition. We manipulated field of view levels equally in both viewing conditions using glasses that limit the field of view in real-world conditions and limiting the field of view in virtual-world conditions in a manner equivalent to real-world conditions via HMD. Eighteen participants observed the target with a limited field of view in a real and virtual environment without head movement. Then, we measured perceived distance using the timed imagined walking method, which measures the time taken by each participant to mentally walk to the target. The target was shown three times at three different distances from the participants: 3, 4, and 5 m. For the analysis, we converted time estimates into distance estimates. Consequently, the estimated distance in the virtual environment condition was less than the estimated distance in the real environment condition. And as the field of view shrank, the estimated distance also decreased. The estimated distance did not vary with field of view levels in real-world conditions. In the virtual environment, the estimated distance decreased as the field of view decreased, whereas in the real environment, the estimated distance increased. The implications of the results and some future research directions are discussed below.
