This study was to evaluate the walking speed of elderly people by using the travel route big data collected by travel diary and smart phone application. We analyzed the change of walking behavior in the residential street environments of the elderly whether they had a company or not. We interpreted the meaning based on previous studies. In addition, the characteristics of elderly people's use of the residential street environment were analyzed by comparing the change in spatial speed according to the companion. The result reveals that the usage patterns of the residential street environments change depending on whether they were accompanied or not. First, the elderly tend to do more social activities while walking alone than when they were accompanied. When they were accompanied the social activities occur in empty lot near the residential area. However, the social activities of the elderly occur in open space such as neighborhood park or playground while walking alone. Finally, This study has strength that it empirically analyzes the elderly's walking behavior and usage paths in small outdoor spaces, including residential streets.

The active living of the elderly leads to improve their lives and enhance social networks. In the view of the active living, the walkability is an essential factor for the elderly's daily life. To support the active living, making age-friendly environment is important. Considering that the elderly mainly carry out activities through walking, making the age-friendly walking environment is a preliminary action. The existing studies applied various methods such as surveys by experts. In spite of the benefits in theirs, there is still a limitation that current walkability measurement methods did not incorporate the actual elderly's walking activity. Thus, the purposes of this study is to measure the elderly's walking quantitatively using a wearable sensor, and to investigate the feasibility of comparing several walking environments based on the data collected from the actual elderly's walking. To do this, experiment was conducted in four types environments with 22 senior subjects. The walkability was measured by walking stability represented quantitatively as Maximum Lyapunov Exponent (MaxLE). Through the experiment results, it was confirmed that the stability of the elderly walking was different according to the walking environment, which also meant that bodily responses (walking stability) is highly related to walkability. The results will provide an opportunity for the continuous diagnosis of walking environments, thereby enhancing the active living of the elderly.

Walking is not only an essential component of the human mobility, but also is a good exercise. Inability to walk freely can reduce an individual's quality of life and independence substantially. Being a relatively low impact activity, walking is particularly good for the elderly and research has shown that regular walking in the elderly reduces the chance of fall-related injuries and mental diseases as well. In spite of the documented benefits of regular walking, it is still difficult to walk without the aid of assistive devices for the frail elderly who have lower extremity problems. Assistive walking devices(AWD), such as crutches, canes, hiking-poles, T-Poles and walkers, are often prescribed to the elderly to make their walking be safe and efficient. Many researchers have demonstrated the effects of AWDs such as reducing lower extremity loading, improved dynamic/gait stability, yet, no study has been done for gait pattern when the elderly gait with AWDs. Therefore, the purpose of this study was to examine whether T-Poles, one of the AWDs, change the elderly gait pattern. Eight community-dwelling female elderly participated in this study. Laboratory kinematics during walking with T-Poles(PW) and with out T-Poles(NPW) was assessed. PW showed significant increase in step width, stride length, gait velocity and decrease in swing time. No significances were found in lower body joint angles but meaningful trend and pattern were found. Maybe the reason was due to the participants. Our participants were healthy enough so that the effect of T-Poles was minimum. PW also showed typical gait phases which are no single support phase during a gait cycle. It indicates that walking with T-Poles may guarantee safe and confident walking to the frail elderly.

This study compares the gait characteristics of elderly women during barefoot walking and walking with sneakers. We measured foot angles, max foot pressure, peak plantar pressure of each plantar region, velocity of Center of Pressure(COP), and axis shifting of COP with an RS-scan system. Elderly women's foot angles were narrower when walking with sneakers than when barefoot walking. We found that the subtalar joint angle (representing ankle joint flexibility) affected walking stability. Regarding the peak plantar pressure of each foot region, pressures were high in the medial regions and the pressures greatly varied depending on the region measured during barefoot walking. The COP moved significantly faster when walking with sneakers than barefoot walking and suggests that elderly women walked faster in sneakers. Axis shifting of the COP decreased during walking with sneakers and indicated that gait balance improved when walking with sneakers. The findings of the present study can be utilized as foundational data for elderly women's gait characteristics as well as data for the production of functional footwear. Future research that focuses on various types of shoes, age groups, and gender are recommended for the development of more functional footwear for stable gaits.

본 연구의 목적은 노인과 정상 성인의 보행경로 너비에 따른 보행 시, 시 공간적 보행 변수의 변화를 알아보기 위함이다. 연구의 대상자는 낙상의 경험이 없는 건강한 노인 20명과 20대 성인 18명으로 하였으며, 3가지 다른 너비의 보행경로(평상시 보행(usual walking), 좁은 너비 보행(narrow base walking), 한줄 보행(centerline-guided walking)에서 보행을 실시하였다. 평상시 보행은 보행경로에 제한을 두지 않았고, 좁은 너비 보행은 각 대상자의 양측 ASIS 사이의 거리를 1/2로 나눈 너비를 보행경로로 설정하였으며, 한줄 보행은 보행경로 중앙에 한 줄을 표시하여 보행을 실시하였다. 보행을 실시하는 동안, GAITRite system을 이용하여 시 공간적 보행 변수의 변화를 비교 분석하였다. 보행경로 너비에 따른 시 공간적 보행 변수 비교에서 20대 성인은 모든 변수에서 유의한 차이를 나타내지 않았으나, 노인의 경우 보행속도, 분속수, 양 뒤꿈치 사이 기저면, 기능적 보행지수가 통계적으로 유의하게 감소하였다(p<.05). 본 연구의 결과를 통해 노인은 20대 성인에 비해 보행경로의 너비가 좁아질수록 낙상에 대한 두려움으로 인해 보행변수에 영향을 미친다는 것을 확인할 수 있었으며, 이를 통해 노인의 낙상 예방 훈련을 위한 적절한 보행너비에 대한 이론적 근거를 제시할 수 있을 것으로 생각된다.

The purpose of this study is to analyze the daily living area of the elderly using the vast amount of travel route data collected through smart phones. In order to analyze the utilization status of the elderly into the visiting area and the living area, the subway station influence area was typed based on the number and ratio of the elderly visiting and the elderly living there. The characteristics of the elderly visiting area and the living area of the subway station area were derived by analyzing the walking route data for the three types of subway station influence areas where the elderly visit and live. First, we derive the range of visiting area and living area of the elderly near the subway station. Second, we derive the characteristic of moving distance which causes the linked walking of the elderly. Third, destination distribution and facility utilization are influenced by the subject of use, movement pattern, and facility awareness.

This paper has regarded mechanism design of cane-like passive type walking aid for the elderly using 3-RPS parallel manipulator. First, gait patterns of the elderly have been experimented. By means of motion capturing and image processing, we decided loaded forces and places of the cane when the elderly walked with a cane. Using these results we have developed a passive type walking aid. Second, the walking pattern has been simulated using dynamic analysis program, ADAMS and we find out the similarity between the real walking and the simulated walking. Finally after assuring the similarity, with adjusting the new mechanism design to the simulated walking we will decide whether the walking aid is safe and stable when the elderly walks with this cane-like walking aid. This paper will be basis for the development of the mechanism design applying 3-RPS parallel manipulator.

Background: Knee osteoarthritis (OA) causes not only pain during walking but also walking disorders. Therefore, intervention for older patients with OA is important. Objective: To study investigated the effects of kinesio taping (KT) on pain and walking ability in elderly persons with knee OA. Design: One group, pre-post design Methods: This study enrolled 12 community-dwelling elderly people with knee OA. KT was applied on the surrounding structures, including the patellar and bilateral lateral ligaments. Assessment was made using the visual analog scale and GAITRite system to measure pain and walking ability during KT and non-KT conditions. Results: In this study, compared to the non-KT condition, the KT condition showed a significant improvement in walking ability and pain reduction during walking (velocity, cadence, step length, and stride length) (p < 0.05). Conclusion: This study demonstrated that knee KT has a positive effect on pain reduction and walking ability of the elderly with OA.
