Objective: This study was conducted to test the effects of mobile texting and gaming on gait with obstructions under different illumination levels. Design: Cross-sectional study. Methods: Twelve healthy adults aged 20 to 36 years (mean 23.5 years) were tested under six different conditions. All participants used touchscreen smartphones. Testing conditions included: 1) Walking with an obstruction under a bright illumination level; 2) walking with an obstruction with a low level of illumination; 3) walking with an obstruction while texting under a bright illumination level; 4) walking with an obstruction while texting with a low level of illumination; 5) walking with an obstruction while gaming under a bright illumination level; and 6) walking with an obstruction while gaming with a low level of illumination. All participants were asked to text the Korean national anthem by their own phone and play Temple Run 2 using an iPhone 5. Gait variances were measured over a distance of 3 m, and the mean value after three trials was used. A gait analyzer was used to measure the data. Results: Compared to normal gait with obstruction, gait speed, step length, stride length, step time, stride time, cadence while texting and gaming showed significant differences (p<0.05). Differences between the illumination levels included gait speed, step length, stride length, and step time (p<0.05) with no significant differences in stride time and cadence. Conclusions: Dual-tasking using a smartphone under low levels of illumination lowers the quality of gait with obstructions.

최근 승용차의 48%가 수도권에 집중되어 있어 도심의 혼잡이 늘어날 것으로 예상되고 있다. 하지만 일부 도심에서 부설주차장 설치를 제한해야한다는 법률에 제시되어 있어 주차장 공급이 부족할 것으로 예측되고 있다. 따라서 늘어나는 주차수요로 인하여 운전자들이 주차장을 탐색하는데 어려움을 겪는 문제를 해결하기 위하여 본 연구를 실시하였다. 본 연구에서는 주차장 선택이라는 문제가 도보권내에서 발생하는 것이기 때문에 도보권의 개념을 도입하여 구축한 알고리즘을 제시하였다. 본 연구의 결과 이용자의 선호에 따라 선택패턴이 달라지기 때문에 이를 고려하는 것이 타당하고 나아가 유비쿼터스시대가 도래하게 된다면 실시간 정보공유로 인한 더 정확한 정보를 운전자에게 제공할 수 있게 될 것이라는 비전을 제시하고 있다.

PURPOSE: The purpose of this study was to examine the effects of treadmill gait training in an adjusted position from the functional training system on the gait and balance of chronic stroke patients. METHODS: Thirty chronic stroke patients were randomly assigned to either the experimental group, who received treadmill gait training in an adjusted position, or the control group, who received regular treadmill gait training. Both groups underwent a 30-minute comprehensive rehabilitation treatment before receiving an additional 20-minute treadmill gait training. This routine was repeated five times a week for four weeks. To measure the difference before and after training in walking and balance, patients were scored on the following: 10 m walking test (10 MWT), 6 minute walking distance (6 MWD), timed up and go test (TUG), and static standing balance test (stability index). RESULTS: While post-training scores of 10 MWT, 6 MWD, TUG, and stability index for both groups increased significantly compared with pre-training (p<.05), the experimental group showed greater improvement than the control group (p<.05). The scores of the experimental group increased significantly by 9% in the 10 MWT, 11% in 6 MWD, 13% in the TUG, 8% in the stability Index (eye opened), and 10% in the stability index (eye closed). CONCLUSION: Treadmill gait training in an adjusted position from the functional training system would be a useful gait training method to improve walking and balance of chronic stroke patients.

Objective: The purpose of this study is to find the problems of stability when people use the bassinet as an ambulatory aid for old people. Background: Many aged people use a bassinet as ambulatory aid. But the safety of using the bassinet as ambulatory aid has not been verified yet. Method: The 13 university-students who don't have musculoskeletal disorders volunteered to participate in this study. According to structural analysis of the both tools, we compared the structural stability of an outdoor rollator with the structural stability of a bassinet. And when the participants walked using both tools, the motions were captured and analysed. We measured the angle of shoulder joint and the angle of trunk from the ground when the participants were walking. And we found the distance from participants' pressure cone apex and greater trochanter. Results: Following the structural analysis, the bassinet has the lower structural stability than the outdoor rollator. When the people used the bassinet as ambulatory aid, the angle of the shoulder joint was bigger than to use the outdoor rollator. The angle of trunk wasn't different between the outdoor rollator and the bassinet. And distance from pressure cone apex to greater trochanter was far to use the bassinet than to use the outdoor rollator. Conclusion: Through the structure analysis and gait analysis of the bassinet and the outdoor rollator, we can be aware of that the bassinet has problem of stability. Therefore the people who use the bassinet as an ambulatory aid, especially supporting body weight, may be hurt due to the problems of stability. Application: This research can be used for developing a study of the ambulatory aid and preventing the accident when the aged people use the ambulatory aid.

The following study reviewed the walking patterns of stroke patients with hemiplegia, which is called hemiplegic gait of stroke patients. Focusing is given to the changes in the distance and temporal factors of walking, which is called spatiotemporal characteristics, throughout the walking cycle. First, we introduced the definitions of essential terms related to gait and its measure. Second, we reviewed the spatiotemporal characteristics of hemiplegic gait. A main issue was that hemiplegic gait showed significant deviations from normal healthy gait. Although hemiplegia is primarily associated with unilateral motor disorder, changes in almost all spatiotemporal parameters used to assess walking were evident on both the involved and uninvolved sides of the body. Last, we reviewed the changes of spatiotemporal parameters of hemiplegic gait according to the prognosis or status of stroke patients, which may help to give a specific intervention for rehabilitation of stroke.

Purpose : The purpose of this study was to investigate the effect of 2 weeks of backward walking exercise (BWE) on cervical angle and gait parameters in college students with forward head posture. Methods : Fifteen subjects participated in the experiment. All the participants had a craniovertebral angle (CVA) of 55 degrees or less. The purpose of the study was explained to all the subjects prior to participation, and volunteered to take part in the study. A camera capable of taking pictures of the lateral plane was installed at a distance of 1.5 meters from each subject. Images of forward head posture were obtained before and after performing the BWE, and the CVA and craniorotational angle (CRA) were compared pre- versus post exercise. Foot pressure and gait parameters (step length of left and right, stride length, stance of left and right, swing of left and right, step time of left and right, and stride time) were measured using a rehabilitation treadmill. The subjects performed the BWE for 2 weeks. The exercise program consisted of a 5-minute warm-up exercise, 20-minute main exercise, and 5-minute cool-down exercise. In the main exercise, the treadmill speed was set to 2.4 km/h in the first week and 3.4 km/h in the second week. A paired t test was used to compare the CVA and CRA and gait parameters before and after the exercise. Results : Comparison of the CVA and CRA before and after the BWE revealed a significant difference post exercise, with a marked improvement in forward head posture after the exercise (p<.05). Conclusion : Based on the results of this study, the BWE is considered to be an effective exercise for the forward head posture. Also, additional research is needed to shed light on the impact of the BWE on gait parameters.
