Background: There is a research report that lumbar mobilization for healthy people improves the knee extension angles and Q-angle related muscle activity (Q: quadriceps muscle). However, there is a lack of research on the effect of lumbar mobilization on gait variables such as cadence and gait speed, especially when mobilizing the central part of the lumbar spine from posterior to anterior. Objectives: To examine the effect of lumbar central PA mobilization in healthy people on cadence and gait speed. Design: Pilot study. Methods: There were 34 participants in this study. In the experimental group, lumbar posterior-anterior joint mobilization was performed once in Grade III-IV for 5 minutes, focusing on the segment with reduced movement. In the control group, lumbar posteroanterior mobilization was performed once in a total of Grade I-II for 5 minutes. To measure cadence and gait speed, STT-IWS and iSen System (San Sebastian, Spain) were used. Results: The comparison of cadence between groups, CG (Control group) increased cadence was about 6 more than EG (Experimental group) cadence, but it was not statistically significant. The gait speed of EG and CG was .30- .31, which was similar between the two groups, and the before and after values were also similar. There is no statistically significant difference Conclusion: The cadence and gait speed of the experimental group were not statistically significantly different than those of the placebo group.

We report the characterization of a massive (mp = 3:91:4Mjup) microlensing planet (OGLE- 2015-BLG-0954Lb) orbiting an M dwarf host (M = 0:33  0:12M) at a distance toward the Galactic bulge of 0:6+0:4 􀀀0:2 kpc, which is extremely nearby by microlensing standards. The planet-host projected separation is a?  1:2AU. The characterization was made possible by the wide-eld (4 deg2) high cadence (􀀀 = 6 hr􀀀1) monitoring of the Korea Microlensing Telescope Network (KMTNet), which had two of its three telescopes in commissioning operations at the time of the planetary anomaly. The source crossing time t = 16 min is among the shortest ever published. The high-cadence, wide-eld observations that are the hallmark of KMTNet are the only way to routinely capture such short crossings. High-cadence resolution of short caustic crossings will preferentially lead to mass and distance measurements for the lens. This is because the short crossing time typically implies a nearby lens, which enables the measurement of additional eects (bright lens and/or microlens parallax). When combined with the measured crossing time, these eects can yield planet/host masses and distance.

This study addresses the effects of treadmill training on hyperextended knee and cadence in patients with hemiplegia. A single subject research design with multiple baselines across individuals was used for the study. Two patients with hemiplegia participated in the experiment. The experiment consisted of interventions where the patients were asked to ambulate for 15 minutes at a comfortable walking speed on the treadmill with 11% slope grade and were allowed to rest for 10 minutes. Patients, then, were asked to ambulated 20 meters at walkway. The number of occurrences of knee hyperextension and the total number of steps were recorded. The results showed that the occurrence of knee hyperextension decreased by approximately 30% after the first session of the treadmill training and continued to gradually decrease during the following sets of treadmill training. Meanwhile, there was a slight increase in the cadence to a negligible extent. These results suggest that the gait training on the sloped treadmill may be helpful for correcting the knee hyperextension in patients with hemiplegia.

The purpose of this study was to determine whether the biomechanical variables of the walking patterns of the obese children compared with those of normal children would revealing significant differences. Normal(N=25) and obese(N=19) subjects were screened based on a health record which was examined to eliminate any subjects who had any pathological condition related to their gait. Data for a minimum of 5 repeated walking trials were collected using a stop watch and a tape measure. Basic kinematic analyses yielded data based on the following variables : stride length divided by leg length, and cadence divided by leg length. This measurement data was classified by the Obesity Index calculated from by height, weight data. Results showed no significant difference among normal, obese and subjects(p>.05). Difficulties in formulating the experimental condition and poor equipment quality are thought to be reason for the inconclusive results. Future studies might include medical complications such as tibia vara, genu valgum, other diseases caused by obesity.
