Purpose : The purpose of this study was to examine the effects of combination of isotonic and rhythmic stabilization in proprioceptive neuromuscular facilitation on trunk stability and balance in elderly people with chronic low back pain. Subjects : Thirty-two elderly people ($73.78{\pm}8.49$ years of age) who had complaints of CLBP were randomly assigned to 2 groups: experimental group and control group. Methods : Subject trained with combination of isotonic and rhythmic stabilization in proprioceptive neuromuscular facilitation for 4weeks with aim of improving trunk stability and balance. Weight distribution, trunk muscle balance, static balance ability and dynamic balance ability were measured before, at the end of training. Results : Data were analyzed using two-way ANOVA. After the exercise programs, there were significant differences in the weight distribution, trunk muscle balance and dynamic balance ability between the experimental and control group. However there was no significant difference in the one leg stance test(p<.05). Conclusion : This study suggest that PNF programs may be appropriate for improving trunk stability and balance in elderly people with CLBP.

Purpose: This study compares and examines the effects of proprioceptive neuromuscular facilitation (PNF) on patients with chronic low back pain through systematic literature review and meta-analysis. Methods: Domestic literature was searched with combinations of keywords including "proprioceptive neuromuscular facilitation," "PNF," "back pain," and "low back pain" using the Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS), and Korean Medical Database (KMbase). Six studies (n=148) were finally included in the analysis through a selection and exclusion process. The quality of the studies was evaluated using the PEDro scale. Results: According to the meta-analysis results, the low back pains of the PNF group and the contrast group showed a standardized mean difference (SMD) of 2.21 (95% CI: -3.35, -1.07, p=0.01, $I^2=83%$) after intervention. Thus, the PNF group showed a statistically significant decrease in low back pain compared with the control group. In addition, the SMDs of the Oswestry Disability Index (ODI), lung function, and the Roland and Morris Disability Questionnaire (RMDQ) were -1.34 (95% CI: -1.88, -0.79, p<0.01, $I^2=35%$), 1.14 (95% CI: 0.49, 1.79, p=0.01, $I^2=0%$), and -1.59 (95% CI: -2.56, -0.62, p=0.01, $I^2=46%$), respectively. Thus, the PNF group showed statistically significant differences from the control group. Conclusion: At present, there is some limit to obtaining definite results about effect sizes because there are relatively few randomized controlled experiments that analyze the effects of PNF exercise in patients with chronic low back pain. Therefore, continuous efforts should be made to conduct randomized clinical trials and long-term efficacy studies in the future.

Purpose - Korea became a trillion-dollar trading country in 2011. With the exponential increase in Korea's trade volume over the past decades, trade-related administrative burdens per capita for Korea Customs became enormous, for which the government established the Single Window, a trade-facilitating system, in 2004 to enhance the efficiency of customs-clearing procedures for traders. This paper focuses on finding whether the Korean Single Window system affects the country's trade facilitation positively through an empirical methodology. Design/methodology - To find empirical evidence that Single Window affects trade facilitation for the customs-clearing procedure, this study assumes that a time-efficient environment enables the handling of the increase in trade volume, under which four independent variables related to import customs-clearing procedures and two dependent variables to import were adopted for empirical analysis. The import customs procedures are classified into four steps from port entry to declaration acceptance. To understand the relationship between variables, scattered plots and correlation coefficients were calculated. Eight hypotheses were set and underwent simple linear regression. The data for analysis were collected by Korea Customs, and were about the lead time of import, the volume of imports in million USD, and the number of import declarations reported to customs offices on a monthly basis from 2005 to 2013. Findings - Six of the eight hypotheses showed the statistically significant result that lead time in the import customs-clearing procedure positively affects the number of import declaration reports and import volume. Specifically, Hypothesis 1, Hypothesis 2, and Hypothesis 3 strongly support the assumption lead time in import customs declaration has an inverse relationship with the number of import declarations, which means that the shorter the import lead time, the more import declaration increases. Research Limitations/Implications - With limited data accessibility to the government's custom-sclearing procedures, only the import lead time for customs clearance were adopted as independent variables. This paper, however, successfully found that the Single Window system contributed to trade facilitation. Originality/value - This study found that the time-saving Single Window system of Korea Customs enables itself to manage an exponentially-increasing trade volume by creating a trade-facilitating environment for customs personnel and traders, which may be a unique implication found through quantitative methodology.

The purpose of this review are that what is the concept of sport P. N. F and to give the information about proprioceptive neuromuscular facilitation technique when the sport physical therapy will be needed in field. Technique of proprioceptive neuromuscular facilitation are methods of placing specific demands in order to secure a desired response. Greatest emphasis was placed on the application of optimal resistance throughout the range of motion, using many combinations of motions which were related to primitive patterns and employment of postural and righting reflexes. The treatment after sport injury patient is required that two component actions of muscles as well as permitting action to occur at two or more joint. The effect of P. N. F and of sprot P. N. F are reviewed. Implications for treatment of sport disability are suggested.

Purpose: This study examined the effects of an exercise program involving the Proprioceptive Neuromuscular Facilitation (PNF) lower-extremity patterns on the Bone Mineral Density (BMD), balance and lower muscular strength in patients with osteoporosis. Methods: The participants were allocated randomly to 2 groups: experimental group and control group. To evaluate the effects of exercise, the subjects were evaluated using the BMD and Time Up & Go Test and One Leg Stance Test for balance, and the Sit To Stand for lower muscular strength. Results: After the 8 week study, the experimental group showed a significant difference in all items compared to the control groups. Conclusion: These results suggest that a PNF exercise program is effective in patients with osteoporosis. Furthermore, an exercise program involving these patterns can be used in a follow-up program for patients with osteoporosis. Overall, more study will be needed to develop and apply more efficient exercise programs for such patients.

Background : Guillain-$Barr{\acute{e}}$ syndrome(GBS) is a neurologically emergent condition, leading to respiratory insufficiency without an early and appropriate treatment. Thus, the treatment of GBS requires early diagnosis but it is difficult due to the low sensitivity of laboratory tools in the initial stage. Hoffman reflex (H-reflex) and its facilitation by Jendrassik maneuver (JM) are sensitive tools evaluating the central circuit of motor system on the spinal cord level. The aim of this study is to test whether the change of H-reflex and F-wave under the JM is able to detect the early stage of GBS and whether GBS involves the central nervous system (CNS). Material and Methods : All 7 GBS patients who showed normal or nearly normal nerve conduction study were included. The facilitation of H-reflex and changes of F-wave were calculated by measuring the percent difference of H-reflex or F-wave amplitude under JM compared to basal H-reflex of F-wave amplitude. The changes of F-wave and H-reflex in the GBS patients were compared with them of 8 healthy controls. Results : The F-wave amplitudes of both healthy controls and GBS patients did not changed under the influence of JM ($102.4{\pm}24.9%$, $108.7{\pm}29.0%$ respectively). However, the facilitation of H-wave by JM in the GBS patients was absent ($98.8{\pm}5.8%$), even though the H-reflex amplitude I the healthy controls increased under the influence of JM ($124.8{\pm}12.1%$). Conclusions : The loss of H-reflex facilitation in GBS implies that this phenomenon might be the most early change detected in the electrophysiological study and support the early diagnosis, and that GBS might include lesion in the spinal motor CNS.
