The aim of this study is to identify the effects of the correction exercise program on femoral intercondylar distance, Q-angle and plantar pressure in undergraduate with genu varum. A experimental study with a randomized controlled trial design was used. Thirty subjects with genu varum were allocated in two groups: the experimental group (n=15) or the control group (n=15). The experimental group conducted correction exercise program for 30 minutes a day, 5 times a week, for 6 weeks, while the control group did not perform any exercise. The correction exercise program group showed a significant decreased femoral intercondylar distance, plantar pressure of M 4, M 5 (Metatarsal 4, 5). Also the correction exercise program group significantly increased Q-angle, plantar pressure of Toe 2-5 and M 1, M 2, M 3 (Metatarsal 1, 2, 3) (Rt, Lt) (p<.05). Thus, we suggested that the correction exercise program may be suitable intervention to improve normal alignment in undergraduate with genu varum.
The purpose of this study was to investigate the problems of low signal-to-noise ratio(SNR) of single-shot turbo spin echo(SS-TSE) by quantifying numerically decreased signal to noise ratio. Thirty five patients without brain disease underwent diffusion MRI in 3T scanner from July to October in 2015. Single shot echo planar imaging(SS-EPI) which is conventionally used in MRI was taken to compared SS-TSE in SNR of medulla oblongata. As a result, SNR of SS-TSE diffusion(b0=314.41±42.96, b1000=117.33±14.04) is than SS-EPI diffusion(b0=514.84±48.97, b=208.65±25.70) lower in b=0 image(38.9%) and b=1,000 image(43.8%). Thus, diffusion MR using SS-EPI of MS-EPI should be taken for diagnosis of disease in brain stem due to decreased SNR of diffusion using SS-TSE.Keyword: Diffusion weighted image, Single-shot turbo spin echo, Single-shot echo planar imaging, Signal to noise ratio, Brain stem
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
