Purpose: This study was to determine the effect of a smartphone video educational program on educational satisfaction of patients in rehabilitation units at a university hospital. Methods: The subjects of this study were 60 stroke patients recruited and divided into two groups; experimental group (n=30) and control group (n=30). Subjects in the experimental group and control group conducted conventional physical and occupational therapy. In addition, only the experimental group provided smartphone video information for a total of 15 sessions. The video consisted of five episodes (10 minutes each) viewed a total of 15 times (for each video three times). The outcome was assessed by educational satisfaction. Result: After inervention, both groups revealed significant increased awareness of prevention of infection educational satisfaction and prevention from falling educational satisfaction and exercise program educational satisfaction. However, the experimental group was more effective than the control group relative to heightened awareness of increasing prevention of infection prevention from falling and exercise program. Conclusion: We suggest that a smartphone video educational program may be effective in improving awareness of the prevention of infection, prevention from falling, and exercise program educational satisfaction. Therefore, video-based information is beneficial for such patients. Further studies are needed for better understanding of the effectiveness of a smartphone video educational program in rehabilitation units at a university hospital.

PURPOSE: Most gait assessment tools are expensive and require controlled laboratory environments. Tri-axial accelerometers have been used in gait analysis as an alternative to laboratory assessments. Many smartphones have added an accelerometer, making it possible to assess spatio-temporal gait parameters. This study was conducted to confirm the reliability and validity of a smartphone-based accelerometer at quantifying spatio-temporal gait parameters of stroke patients when attached to the body. METHODS: We measured gait parameters using a smartphone accelerometer and gait parameters through the GAITRite analysis system and the reliability and validity of the smartphone-based accelerometer for quantifying spatio-temporal gait parameters for stroke patients were then evaluated. Thirty stroke patients were asked to walk at self-selected comfortable speeds over a 10 m walkway, during which time gait velocity, cadence and step length were computed from smartphone-based accelerometers and validated with a GAITRite analysis system. RESULTS: Smartphone data was found to have excellent reliability ($ICC2,1{\geq}.98$) for measuring the tested parameters, with a high correlation being observed between smartphone-based gait parameters and GAITRite analysis system-based gait parameters (r = .99, .97, .41 for gait velocity, cadence, step length, respectively). CONCLUSION: The results suggest that specific opportunities exist for smartphone-based gait assessment as an alternative to conventional gait assessment. Moreover, smartphone-based gait assessment can provide objective information about changes in the spatio-temporal gait parameters of stroke subjects.

In the paper, we developed the mobile based rehabilitation system for patients with upper extremity hemiplegia after stroke and evaluated clinical usefulness and effectiveness of the system. The sensors built in the smartphone were used to track patients' upper limb motion and the movements was transferred to the tablet PC through bluetooth connection so that the game contents could be interact with the movements. The rehabilitation game contents was based on Brunnstrom stage(B-stage), and was designed to lead accurate movement of upper limb. For the clinical evaluation of the effectiveness, 11 patients were recruited and make them perform an exercise of their wrist, shoulder, and forearm using the system for two weeks. The change of upper limb motor function was measured using fugl-meyer assessment(FMA), Brunnstrom stage(B-stage). And the change of quality of life was measured using EuroQoL-5 Dimension(EQ-5D), Beck Depression Inventory(BDI). The results showed significant improvement in upper limb function but not in quality of life. We verified mobile based rehabilitation program could be useful and effective for the clinical use.

Purpose: Smartphones, which are widely used worldwide to detect acceleration and position, have been used in the area of rehabilitation medicine in recent clinical research studies and tests. The aim of the present study was to determine the feasibility of using a smartphone application based on center of movement (COM) displacement to measure gait parameters in stroke patients in the clinical field of rehabilitation medicine. Methods: The study consisted of 30 stroke patients. The COM was measured using a smartphone application, Gait Analysis Pro, during a 6-m walk. Each patient performed three 6-m walking trials, and the smartphone application measured gait duration, gait speed, step length, cadence, and vertical and lateral displacement of the COM. The Kolmogorov-Smirnov test was conducted to determine the normality in gait parameters, and a repeated one-way analysis of variance (ANOVA) was performed to determine the consistency among the three trials. A p value of 0.05 was considered statistically significant in all the tests. Results: In all the measured parameters, the smartphone application showed a normal distribution, as shown by the results of the Kolmogorov-Smirnov test. There were no significant differences among the three repetitive walking trials. Conclusion: These results suggest that the smartphone application can be used for evaluating gait in stroke patients, as well as in healthy adults. However, prior to using the smartphone application in the clinical field, further research involving three-dimensional gait analysis is needed to enhance the confidence level of the findings.

Purpose: This study investigated the effects of virtual reality-based task training (VRBTT) using a smart glove on upper extremity function and activity of daily living in stroke patients. Methods: Twenty-nine patients with chronic stroke disease were randomly allocated to two groups: the VRBTT group (n=14) and the control group (n=15). All patients received 30 minutes of standard occupational therapy, 5 times a week, for 8 weeks. The VRBTT group performed an additional 30 minutes of virtual reality-based rehabilitation training, 5 times a week, for 8 weeks. Results: Both groups showed significant improvements in upper extremity function, yielding an increase in FMA and K-WMFT (p<0.05). There was a more significant increase in the VRBTT group before and after interventions (p<0.05). There was no significant difference in MAS for the control group (p>0.05); however, there was a significant increase for the VRBTT group (p<0.05). In the activities of daily living, there was a significant difference in the values for K-MBI (p<0.05). In addition, both groups showed a significant increase for K-MBI and K-RNLI (p<0.05). Conclusion: This study showed that VRBTT using smart gloves can have a more positive effect on upper extremity function and activities of daily living in stroke patients than conventional intervention methods. A variety of virtual reality-based contents and glove-shaped wearable devices will help stroke patients in rehabilitation clinics recover and return to society.
