Purpose: The purpose of this study is to compare kinematics and kinetics on the knee joint between stair gait with unstable shoes and barefoot in healthy adult women. Methods: Seventeen healthy adult women were recruited for this study. The subjects performed stair ascent and descent with unstable shoes and barefoot. The experiment was repeated three times for each stair gait with unstable shoes and barefoot. Measurement and analysis of the movements of the knee joint were performed using a three-dimensional analysis system. Results: Statistically significant differences in the knee muscle force of semimembranosus, biceps femoris-long head, biceps femoris-short head and sartorius, patellar ligament, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair ascent. Statistically significant differences in the knee muscle force of sartorius, rectus femoris, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair descent. Statistically significant differences in the knee flexor moment of semitendinosus, biceps femoris-long head, biceps femoris-short head, sartorius, rectus femoris, vastus intermedialis, medial gastrocnemius, and lateral gastrocnemius were observed between unstable shoes and barefoot gait during stair ascent. Conclusion: Therefore, wearing unstable shoes during stair gait in daily life is considered to influence knee joint kinematics and kinetics due to the unstable shoes, and thus suggest the possibility that reducing the risks of pain, and knee osteoarthritis, stabilizing the knee joint caused by changes in the loading of the knee joint.

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.

Background: Ankle instability usually occurs after stroke, and contributes to unsafe walking and associated risk of falling in the affected patients. Objective: To investigate the effects of kinesiology taping (KT) on gait and balance ability (center of pressure, CoP) in patients with ankle instability after stroke. Design: One group, pre-post design. Methods: A total of 11 patients with ankle instability after stroke were enrolled. In all subjects, the gait and balance ability were assessed under 2 conditions: KT and barefoot. Gait and balance ability was assessed using GAITRite system and FDM-S platform. Results: Comparison between KT and barefoot condition, KT condition was significantly higher in velocity, cadence, step length, and stride length than barefoot condition (P<.05). KT condition was significantly lower in CoP path length and sway speed than barefoot condition (P<.05). Conclusion: KT indicated potential as a helpful method for walking and balancing ability in patients with ankle instability after stroke. Therefore, this study recommends KT as an option applicable to the stroke with ankle instability.

Purpose : The purpose of this study is to examine the effect of different heel heights on gait deviation and balance. Method : Participants were 16 women majoring in physical therapy in Kyungbuk college, located in Yeong-ju, North Kyungsang Province. Balance and gait patterns were measured by Good Balance and GAIT Rite. Result : Statistically significant differences were found in swing right measured by Gait-rite, and also in Analyze End, Ant-post, Med-Lat, and gait ability score(p < .05) regarding dynamic balance ability. Conclusion : There was no statistically significant difference in gait ability between those who walked barefoot and highheeled. However, balance ability was different "between them". This shows that heel height can lead to decrease in gait ability. Further research should include more participants and use a wide range of heel heights.

본 연구는 맨발 보행과 운동화 착용 보행에서 보행주기의 차이를 비교하여 보행역학에 따른 신발 개발에 기초자료를 제공하고자 한다. 발의 변형과 이상이 없는 정상 성인 여성 30명을 대상으로 보행 주기를 측정하였다. 먼저 운동화를 착용하고 보행하여 주기를 측정한 후, 맨발로 보행하여 주기를 측정하여 데이터를 얻었다. 이후 두 데이터를 대응표본 T-test를 이용하여 비교하였다. 실험 결과 맨발 보행에서 입각기 좌측(p<.001), 우측(p<.005), 체중부하기 좌측(p<.009), 우측(p<.002), 전유각기 좌측(p<.002), 우측(p<.011), 양하지 지지기(p<.004)가 증가하였고, 중간 입각기 좌측(p<.016), 우측(p<.001), 유각기 좌측(p<.001)이 감소하였다. 이는 맨발 보행이 다양한 발의 감각의 입력을 증가시켜 보행안정성이 높은 보행이 가능해 졌다고 보여 지며, 향후 보행 주기에 의거하여 맨발보행과 가까운 신발 개량이 필요하다고 사료된다. 향후 신발의 개량을 위해 신발 종류에 따른 보행주기 연구가 필요할 것이다.

Purpose: The purpose of this study is to compare kinematics on lower limbs between stair walking with high heel and barefoot in healthy adult women. Methods: 18 healthy adult women were recruited in this study. The subjects performed stair ascent and descent with high heels and barefoot. The experiment was conducted in random order and repeated three times for each stair walking with high heels and barefoot. The movements of lower limb joints were measured and analyzed using a three-dimensional analysis system. Results: The ankle, knee, and hip flexion angles on the sagittal plane exhibited statistically significant differences between stair ascent and descent with high heels and barefoot. The pelvic forward tilt angles showed statistically significant differences only during stair ascent. The ankle inversion, hip abduction and pelvic lateral tilt angles on the frontal plane showed statistically significant differences between stair walking with high heels and barefoot. On the transverse plane, the hip rotation angles showed statistically significant differences between the high-heeled and barefoot gait during stair ascent and descent. However, the pelvic rotation angles showed no statistically significant differences. Conclusion: Therefore, wearing high-heeled shoes during stair walking in daily life is considered to influence lower limb kinematics due to the high heel, and thus poses the risks of pain, and low stability and joint damage caused by changes in the movement of lower limb joints.

The purpose of this study was to investigate the immediate effect of fabric ankle-foot orthosis on spatiotemporal gait parameters, compared to a barefoot condition in children with spastic cerebral palsy. Eleven children with spastic cerebral palsy participated in this study. Spatiotemporal gait parameters were measured with the GAITRite system. Fabric ankle-foot orthosis significantly improved Timed Up and Go test time and gait velocity. There was no significant difference in cadence. The step time significantly improved in both the more and less affected foot compared to the barefoot condition. The step length of the affected foot also significantly improved, but there was no significant difference in the step length of the less affected foot. There was significant improvement in the stride length of both the affected and less affected foot, but no significant difference in single stance or double stance. The fabric ankle-foot orthosis could improve stability, and selective control of the joint and promote better walking in children with cerebral palsy. Consequently, the fabric ankle-foot orthosis might be an alternative assistive device for neurological populations as a primary role instead of the typical ankle-foot orthosis.
