Even though many researchers studied the foot shape and dimension, those applications lacked. The purpose of this study was to develop insole pattern of elderly women according to footprint. Discrepancy in the classification criteria among of foot parameters complicates attempts for elderly women classification of foot sole. To develop a footprint-based classification technique for the classification of foot sole types by allowing simultaneous use of several parameters. Foot sole data from static standing footprints were recorded from 48 elderly women. The factors of footprint shape were determined. Cluster analysis was applied to obtain individual foot sole classifications. The classification model of foot insole is proposed for a classification of footprint in elderly women. An application of ANOVA, Duncan's analysis, frequency analysis, factor analysis, and cluster analysis have been made to footprint data. In order to make clear foot sole characteristics, the factors of footprint shape have been discussed. The results are as follows. The factors of footprint shape have been classified into four types: foot length, sole slope, outside sole slope, and foot width. The types of foot sole shape have been classified into four types: longed, shortened, outside sloped, and toes sloped.

Purpose: This study was undertaken to investigate the effects of foot reflexo-massage on physical, psychological, and physiological parameters in patients with osteoarthritis of the knee. Method: This study was employed non-equivalent control group pretest-posttest time series experimental design. The subjects of this study were 47 elderly patients with osteoarthritis of the knee from two different nursing homes in Deajeon. The patients were divided into two groups; 26 patients in experimental group, the rest in control group. Each patient in experimental group received the 30-minute foot reflexo-massage, 3 times per week for 4 weeks. The dependent variables of each patient were measured before treatment, after 2 weeks and after 4 weeks during the treatment session. The collected data was analyzed using the Social Package Social Science(version 10.0) software program. Result: There were significant differences in the flexion angle of both knees; the flexion and extension muscle strength of both knees; systolic blood pressure; POMS; plantaris skin temperature and blood velocity of dorsalis pedis artery between the two groups over different the three measurement times. Conclusion: The results suggest that foot reflexo-massage could be an effective intervention to improve physical, psychological and physiological parameters for patients with knee osteoarthritis.

Purpose: To investigate the relationship between radiographic parameters of the forefoot and plantar pressure in patients with hallux valgus. Materials and Methods: Plantar pressures of 21 patients with hallux valgus were examined with EMED-ST system. The data were compared with the parameters on the simple weightbearing dorsoplantar radiographs of the feet. The radiographic parameters that were measured were hallux valgus angle, 1-2 intermetatarsal angle, relative lengths of the metatarsals which were measured with the methods described by Maestro et al. and Okuda et al. Results: Statistically significant correlation was found between peak pressures under 2, 3 metatarsal heads and the relative lengths of 2, 3 metatarsals which were measured with the method described by Maestro et al. However they could explain only 13% of the pressures under the 2, 3 metatarsal heads by multivariate analysis. Conclusion: These results suggest that we cannot predict the plantar pressures under the foot with the parameters on the simple weightbearing dorsoplantar radiographs of the feet.

Purpose; This study was aimed to identify the effect of foot reflexology massage on climacteric symptom, fatigue and physiologic parameters of middle-aged women. Method; A non-equivalent pretest-posttest experimental design was used. Participants were recruited from the Community Health Center in Busan, Korea. Forty participants were assigned to either an experimental group(20) or a control group(20). Foot reflexology massage was administered twice a week for 6 weeks in the participant in experimental group. Results: There were statistically significant differences in climacteric symptom, fatigue, total cholesterol and cortisol level. However, there were no statistically significant differences in triglyceride, high density lipoprotein and low density lipoprotein. Conclusion; These results suggest that foot reflexology massage could be utilized as an effective nursing intervention to reduce climacteric symptom and fatigue in middle-aged women.

The structural and biomechanical characteristics of pelvic and foot are important factors of back pain, but it is still complicated to clearly explain the relationship among them. The purpose of this study was to find out the characteristic of pelvic parameters and biomechanics of foot in patients with low back pain. Thirty-three female subjects with chronic low back pain were enrolled and ODI and VAS score were measured for back pain index. All subjects were taken the X-ray examination for major pelvic parameters and foot scan analysis for foot pressure, gait angle, fore-foot/rear-foot peak pressure ratio and asymmetric index. Statistical analysis were performed to examine the inter-relation between the measurement. As a result, it was shown the positive interrelation between back pain and F/R ratio, but others were not shown the relationship related to low back pain. And there were correlations between the lumbo-pelvic structure and biomechanics of foot in some aspects, but the causal relationship between them are still indefinable. In order to get more information about structures and biomechanics related to low back pain, subsequent researches are needed.

Background: Foot drop is a common symptom in stroke patients. Tape applications are widely used to manage foot drop symptoms. Previous studies have evaluated the effects of static and dynamic balance and gait on foot drop using kinesiology tape; however, only few studies have used dynamic tape application in stroke patients with foot drop. Objects: The purpose of this study was to investigate the immediate effects of dynamic taping, which facilitates the dorsiflexor muscle, on static and dynamic balance and gait speed in stroke patients with foot drop. Methods: The study included 34 voluntary patients (17 men, 17 women) with stroke. The patients were randomly assigned to the experimental group (n = 17), wherein dynamic taping was used to facilitate the dorsiflexor muscle, or the control group (n = 17), wherein kinesiology taping was used. Before the taping application, velocity average, path-length average, Berg balance scale, and timed up and go test (TUG) were recorded to measure static and dynamic balance, whereas the 10-meter walk test (10MWT) was used to measure gait speed. After the taping application, these parameters were re-evaluated in both groups. Repeated measure analysis of variance was used. Statistical significance levels were set to α = 0.05. Results: Except for the 10MWT scores in the control group, significant differences were noted in all the parameters measured for static and dynamic balance and gait speed between the pre and post-test (p < 0.05). However, the parameters showed significant interaction effects between group and time in the TUG and 10MWT (p < 0.01). Conclusion: These results indicate that compared with kinesiology taping, dynamic taping used in chronic stroke patients with foot drop had a more significant effect on dynamic balance and gait speed.

This study examined the differences in spatio-temporal parameters, joint angle, ground reaction force (GRF), and joint power according to the changes of gait speed for trans-tibial amputees to investigate the features of the energy-storing foot for sports. The subjects walked at normal speed and at fast speed, wearing a single-axis type foot (Korec) and an energy-storing foot for sports (Renegade) respectively. The results showed that Renegade yielded faster gait speed as well as more symmetric gait pattern, compared to Korec. However, as gait speed was increased, there was no significant difference in kinematics, ground reaction force, and joint power between two artificial foots. This was similar to the results from previous studies regarding the energy-storing foot, where the walking velocity and gait symmetry have been improved. Nevertheless, the result of this study differed from the previous ones which reported that joint angle, joint power, and GRF increased as the gait speed increased except spatio-temporal parameters.

Objectives: This study investigated the change of foot rotation angle of gait analysis parameters according to gait improvement in post-stroke hemiplegic patients. Methods: We measured the foot rotation angle of eight post-stroke hemiplegic patients at the time of dependent and independent gait. Results: The foot rotation angle of the paralyzed side reduced closer to normal average according to gait improvement, but the non-paralyzed side not significantly. Conclusions: Improvement of foot rotation is an important thing for independent gait of post-stroke hemiplegic patients so this treatment seems worthy of being considered in clinical trials.

A structured beam laser is often used to scan object and make 3D model. Multiple cameras are inevitable to see occluded areas, which is the main reason of the high price of the scanner. In this paper, a low cost 3D foot scanner is developed using one camera and two mirrors. The camera and two mirrors are located below and above the foot, respectively. Occluded area, which is the top of the foot, is reflected by the mirrors. Then the camera measures 3D point data of the bottom and top of the foot at the same time. Then, the whole foot model is reconstructed after symmetrical transformation of the data reflected by mirrors. The reliability of the scan data depends on the accuracy of the parameters between the camera and the laser. A calibration method is also proposed and verified by experiments. The results of the experiments show that the worst errors of the system are 2 mm along x, y, and z directions.
