The purpose of this meta-analysis study was to investigate the effect of lumbar stabilization exercise on low back pain by analyzing Korean studies. Studies for the analysis were searched in electronic bibliographic databases by using the keywords ‘lumbar stabilization exercise’ and ‘low back pain’. Only randomized controlled trials (RCTs) and clinical controlled trials (CCTs) were included. Of the 36 studies identified in the search, 11 studies met the study criteria and were thus included in the meta-analysis.

Only randomized controlled trials (RCTs) and clinical controlled trials (CCTs) were included. Of the 36 studies identified in the search, 11 studies met the study criteria and were thus included in the meta-analysis. As a result, lumbar stabilization exercise showed a large effect size(ES) on back pain(ES, 0.84; 95% confidence interval, 0.55–1.22, p=0.025). In the analysis of the subcategorical variables, the RCTs showed larger ES(0.921) than the CCTs(0.693) and static+dynamic exercise showed larger ES than static exercise (0.675). In the analysis of the subcontinuous variables, as the exercise duration (weeks) and number of exercise per week increased, pain decreased(p<0.05). Our results indicated that lumbar stabilization exercise had a beneficial effect on low back pain. In the future, accumulation of more research studies about lumbar stabilization in Korea will lead to more systematic and comprehensive analyses.

가상현실기반 재활프로그램이 뇌졸중환자의 균형에 미치는 영향 : 국내연구에 대한 메타분석

노정석,Roh, Jung-suk 대한물리치료과학회 2017 대한물리치료과학회지 Vol.24 No.1

Purpose : The aims of this study was to conduct a systematic literature review with meta-analysis to investigate the effect of virtual reality based rehabilitation program on balance of patient with stroke in Korean studies. Method : The studies for analysis were searched in electronic databases(Research Information Sharing Service; RISS, Korean Studies Information Service; KISS, DBpia, e-articles, National Assembly Library). The key words for search were 'virtual reality', 'stroke', and 'balance' and only randomized controlled trials and clinical controlled trials were included. Of 40 studies identified in the search, 20 studies met the criteria of this study and included in this meta-analysis. Result : The results were as follows: 1) The overall effect size of virtual reality based rehabilitation program was 0.557(95% critical interval; 0.340~0.774). 2) In the analysis of sub-categorical variables, effect size was as follows; the commercial game type(0.621) > virtual environment type(0.335); the dynamic balance measurement(0.750) > static balance measurement(0.226); randomized controlled trial(0.653) > clinical controlled trial(0.275); and thesis type(0.706) > article of journal type(0.339). 3) In the analysis of sub-continuous variables, as time of program(per session) increased, the balance increased(p<0.05). Conclusion : The results of this study showed that virtual reality based rehabilitation program moderately improves the balance of stroke patient. Further studies are recommended to investigate the effect of sub-variables related to virtual reality programs on motor functions of patient with stroke.

집중방식이 과제수행에 미치는 영향

노정석,김장환,Roh, Jung-Suk,Kim, Jang-Hwan 대한물리치료과학회 2006 대한물리치료과학회지 Vol.13 No.3

The purpose of this study is to introduce the effect of attentional focus on performance of task. Previous studies has shown that motor learning can be enhanced by directing performers's attention to the effects of their movements(external focus), rather than to the body movement producing the effects(internal focus). Wulf and colleagues have invoked the 'constrained action hypothesis' to explain the comparative benefits of adopting an external rather than an internal focus of attention. This hypothesis proposed that when performers utilize an internal focus of attention, they may actually constrain or interfere with automatic control processes that would normally regulate the movement, whereas an external focus of attention allows the motor system to more naturally self-organize. Electromyography(EMG) was used to determine neuromuscular correlates of external versus internal focus differences. EMG activity was lower with an external relative to an internal focus. This suggest that an external focus of attention enhances movement economy, and presumably reduces 'noise' in the motor system that hampers fine movement control. Focusing on a more remote effect seems to facilitate the discriminability of the effect from the body movements that produced it and to be more beneficial than focusing on a very close effects. There might be an optimal distance of the effect, at which ti wis easily distinguishable from the body movement but at which it is also still possible for the performer to relate this effect to the movement techniques. Future Studies of motor learning of patient need to accommodate these new finding and account for the role of the learner's attentional focus and its influencing on learning.

Parotec System을 이용한 족저압 측정의 신뢰도

노정석,김택훈 한국전문물리치료학회 2001 한국전문물리치료학회지 Vol.8 No.3

In-shoe measurement systems allow the clinician and researcher to examine the pressure parameters within the shoe. The purpose of this study was to investigate the test-retest reliability of plantar pressures using the Parotec system over speeds and plantar regions. Seventeen healthy subjects were recruited for the study. Sampling rate was 100 Hz, and data of six variables (pressure on medial heel, lateral heel, 1st metatarsal head, 5th metatarsal head, and great toe and total impulse) were collected in four different gait speed (1.0 m/sec, 1.5 m/sec, 2.0 m/sec, and comfortable walking speed) in each day. The result indicates fair to excellent reliability between the two day test. Intraclass correlation coefficients (ICCs) ranged from .693 to .979, and range of reliability was similar depending on the speed and plantar region. In most cases, data recorded by the Parotec systems provide good evidence for the reliability.

컴퓨터 작업 동안 키보드의 위치가 척수손상자의 근활성도에 미치는 영향

박수현,정민예,유은영,박수현,이진,고상백,노정석 대한작업치료학회 2012 대한작업치료학회지 Vol.20 No.2

목적 : 본 연구는 상위흉수손상군, 하위흉수손상군, 정상군을 대상으로 체간과 상지의 컴퓨터 사용과 관련된 여덟 가지 근육의 활성도를 측정하여 흉수손상자에게 적절한 키보드의 위치를 제시하고자 실시되었다. 연구방법 : 연구대상자는 미국 척수 손상 협회(American Spinal Injury Association; ASIA) A 또는 B의 흉수손상자 중 상위흉수손상자(T2-T8) 9명, 하위흉수손상자(T9-T12) 11명, 그리고 정상인 9명이었다. 적절한 키보드의 위치를 알아 보고자 두 가지 위치 즉, 팔꿈치 굽힘 100°위치와 팔꿈치 굽힘 70°위치에서 근활성도를 측정하였다. 모든 대상자는 2분간 메트로놈의 박자에 맞춰 키보드 중간열의 키를 1초에 4타의 속도로 타이핑하였으며 이때 표면근전도기를 이용하여 목과 어깨의 목세움근, 위등세모근, 앞어깨세모근, 뒤세모근, 중간등세모근과 손목폄근군, 그리고 척수손상자의 체간유지 보조근육인 넓은 등근과 큰가슴근의 근활성도(%RVC)를 측정하였다. 결과 : 상·하위흉수손상군의 측정치는 정상인과 동일하게 팔꿈치 굽힘 100°의 자세에 비해 팔꿈치 굽힘 70°인 위치에서 위등세모근, 손목폄근군, 앞어깨세모근의 활성도가 유의하게 낮게 나타났다. 또한 하위흉수손상군의 경우 정상인과 다르게 팔꿈치 굽힘 100°높이에서 목세움근과 넓은등근의 활성도가 유의하게 증가하였다. 결론 : 흉수손상자의 체간과 상지의 근긴장도를 감소시키기 위해 적절한 키보드 위치는 팔꿈치 굽힘 70°정도의 높이였다. 차후 연구에서는 보다 많은 척수손상자를 대상으로 장시간의 포괄적 컴퓨터 작업을 적용하여 장애특성에 적합한 VDT 환경을 파악하는 연구가 필요할 것으로 사료된다.

대한물리의학회지 논문의 주제어와 MeSH용어의 비교

노정석 ( Jung Suk Roh ) 대한물리의학회 2012 대한물리의학회지 Vol.7 No.3

Purpose The purpose of this study was to investigate the coincidence between keywords of Journal of the Korean Society of Physical Medicine (JKSPM) and MeSH terms, a controlled vocabulary used in MEDLINE. Methods A total of 838 keywords used in 252 papers of JKSPM from Vol.1, No.1, 2006 to Vol.7, No.1, 2012 were compared with MeSH terms. All of keywords are classified to three large categories; complete coincidence, incomplete coincidence, and complete incoincidence. Results The keywords in complete coincidence category were 183(21.8%), the keywords in incomplete coincidence category were 378(45.1%), and the keywords in complete incoincidence category were 277(33%). The most used keyword in complete coincidence category was ``stroke`` and in complete incoincidence category was ``balance``. The most used keyword matching entry terms in incomplete coincidence category was ``elderly``. Conclusion The rate of complete coincidene of keywords with MeSH terms was not higher than the rates of incomplete coincidence and complete incoincidence. It is necessary to understand MeSH terms more accurately and specifically. The JKSPM should ask the authors to use MeSH terms as keyword when they submit the paper.
