Purpose: This study examined the dynamic peak plantar pressure under the foot areas in those with a functional leg length inequality. Methods: The dynamic peak plantar pressure under the foot areas in an experimental group with a functional leg length inequality (n=20) and a control group (n=20) was assessed a using the Mat-Scan system (Tekscan, USA). The peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th metatarsal head (MTH), mid foot, and heel was measured while the subject was walking on the Mat-Scan system. Results: The experimental group had significantly higher peak plantar pressure under all foot areas when the dynamic peak plantar pressure in the short leg and long leg sides was compared. The control group had a significantly higher peak plantar pressure under the 1st, 2nd, 3-4th, and 5th MTH when the dynamic peak plantar pressure in the short leg and long leg sides were compared. The experimental group showed a significantly larger difference in the dynamic peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th MTH, mid foot and heel than the control group. Conclusion: A functional leg length inequality leads to an increase in the weight distribution and dynamic peak plantar pressure in the side of the short leg.

경추안정화 운동과 경추관절가동술이 경부의 최대근력과 정적근지구력에 미치는 영향을 알아보기 위해 60명을 경추안정화운동군, 경추관절가동술군, 대조군의 3개의 군으로 나누어 각 그룹당 20명씩 무작위 배치하였다. 경추관절가동술과 경추안정화운동은 일주일에서 3회씩 총 3주 동안 시행되었고, 경추안정화운동군은 선자세, 바로누운자세, 엎드려누운자세에서 경추심부근육의 등척성운동을 적용하였다. 경추관절가동술군은 칼텐본 기법을 이용한 관절내 운동을 적용하였다. 경추안정화운동과 경추 관절가동술 모두 최대근력과 정적근지구력이 증가하였고 그 중 경추안정화운동이 경추관절가동술보다 최대근력과 정적근지구력에 더 많은 영향을 미쳤다. The purpose of this study was to identify cervical stabilized exercise and joint mobilization, the difference between them, and the maximum muscle strength and static muscle endurance of each group after the enforcement to general people. Cervical joint mobilization group refers to interarticular exercise (traction, pressure, glide) using with Kaltenborn technique. 3 classes were divided into 20 people each, cervical joint mobilization and stabilized exercise, and the comparison groups were randomized for the study. Both cervical stabilized exercise and joint mobilization increased maximum muscle strength and static muscle endurance. Patients should be able improve muscle stabilization and deep cervical muscle by using joint mobilization when the patient is unable to exercise on their own.

회외발에 대한 거골하 관절가동술이 균형능력에 미치는 영향을 알아보기 위해, 주상골 하강 검사에서 주상골의 하강이 4mm이하의 저가동성인 회외발군 20명을 실험군으로, 정상발군 20명을 대조군으로 하여 거골하 관절가동술을 주 3회 4주간 총 12회 적용한 결과 실험기간에 따라 동요 면적, 동요길이, 동요 최대 속도가 유의하게 감소하였으며, 실험군과 대조군에서 유의한 차이가 있었다. 실험군에서는 기간에 따라 동요 면적, 동요 길이, 동요 최대 속도가 유의하게 감소하였으나, 대조군에서는 기간에 따른 유의한 차이가 없었다. 동요 면적, 동요 길이, 동요 최대 속도에 대한 그룹 간 비교에서 설험 전은 유의한 차이가 없었으나 실험 2주 후, 실험 4주 후, 실험종료 2주 후에서는 실험군이 대조군에 비해 유의하게 낮았다. The purpose of this study was to evaluate the influence of ankle joint mobilization on equilibrium ability of supinated foot. Both Joint mobilization group(n=20) and control group(n=20) were measured an equilibrium ability by Balance performance monitor at pre-test, post-test in 2 weeks, post-test in 4 weeks and follow-up test in 2 weeks. The sway area, sway path length and sway maximum velocity of the joint mobilization group were significantly reduced among the experimental period (p<.05). The reduction of sway area, sway path length and sway maximum velocity were significantly different between the joint mobilization group and the control group at in 2 weeks, 4 weeks and follow-up test(p<.05). In conclusion, we were found that ankle joint mobilization could reduce sway area, sway path length and sway max velocity and improve a balance for the individuals with supinated foot.

The purpose of this study is to understand the structure and biomechanics of the skeletal muscle. The skeletal muscle takes 40 to 45% of the whole body. Stable posture requires a balance of muscle. However, when the muscle strength is unbalanced, movement initiates. The power generated by the muscle is a primary means to adjust the equilibrium of posture and movement. The structural unit of the skeletal muscle is a long cylindrical type muscle fiber which contains hundreds of nucleus. The thickness of muscle fiber is about $10-100{\mu}m$, and its length is about 1-50cm. Muscle fiber is composed of myofibril that is covered with plasma membrane which is called sarcolemma. In understanding the movement of human body, it is important to comprehend the movement of bone and joint and the tension of muscle. Understanding the structure and biomechanics of muscle also provides basic information on clinical treatment of patients.

Background: The purpose of this study is investigate the effects of cervical range of motion (ROM) and forward head posture (FHP) on cervical manual traction in normal adults. Methods: The subjects were randomly assigned to either the experimental group(Female 9, Male 6) who conducted the manual cervical traction or the control group(Female 9, Male 6) who did not conduct the any intervention. The subject in the EG have conducted the 1 set of 10 minutes of manual cervical traction per day, 2 times a week for 6 weeks. The cervical ROM was measured by the digital inclinometer and The factors of FHP was measured by cranial vertebral angle (CVA) and cranial rotation angle (CRA). Results: Comparing the cervical ROM and FHP between the experimental and control groups before and after the experiment, it could be seen that flexion, extension, right lateral flexion, left lateral flexion, CVA and CRA of the experimental group has been increased. Thus, cervical manual traction was resulted in the increased cervical ROM and decrease FHP. Conclusion: In this study, it was confirmed that cervical manual traction affects increase cervical ROM and decrease FHP that play a important role in neck stability and mobility.

Purpose: The purpose of this study was to evaluate the The Influence of contract-relax exercise of PNF on Equilibrium Ability. Methods: The subjects were consisted of thirty patients (14 females and 16 males). They were from 20 to 42 years old and the mean age was 25.03. All subjects were randomly assigned to two groups: contract-relax exercise of proprioceptive neuromuscular facilitation(PNF) group (n=15), control group (n=15). Contract-relax exercise group received contract-relax exercise for about 10 minutes along with therapeutic massage for about 15 minutes, 3 times per week during 4 weeks period. However, control group did not receive intervention during the same 4 weeks. The Balance performance monitor(BPM) was used to measure equilibrium ability. All measurements of each subjects were measured at pre-experiment, after 2 weeks, and post-experiment. Results: The results of this study were summarized below : 1. The sway area of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). 2. The sway path length of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). Conclusion : Contract-relax exercise applied with therapeutic massage can increased equilibrium ability. Additional randomized controlled trials to more fully investigate treatment effects and factors that may mediate these effects are needed.

Purpose: Our study sought to investigate differences in plantar foot pressure as a function of type of pack carried and of changing weight during gait and stance. Methods: Subjects were 40 students with no disabilities. Plantar foot pressure was measured with different types of packs carried and with changing weight of the pack during both gait and stance and while changing feet. During stance while carrying a satchel on the shoulder caused a disproportionate change in plantar foot pressure. An even great imbalance occurred for plantar foot pressure during gait. Results: Using a satchel can influence diseases such as scoliosis that are caused by unbalanced muscle activation and by a disproportionate distribution of the weight of the body. Conclusion: Knowing how to use a pack correctly and how to appropriately adjust the weight of bag should be taught.
