Purpose: This study aimed to verify the impact of the time that the sitting posture is maintained on changes in muscle performance and head alignment. Methods: The subjects of this study were healthy adults aged between 20 and 30 years. Ninety-three subjects participated in this study (male: 57, female: 36). The subjects were divided into a one-hour group, a two-hour group, and a three-hour group. All the subjects adjusted the height of their chair to a comfortable position and then seat for one, two, or over three hours. Both prior to and after the experiment, the muscle performance (muscle strength, endurance, and flexibility) of the subjects was measured. Results: In the 2-hours and 3-hour group, muscle strength, flexibility and endurance reduced significantly before and after the study, and the head alignment significantly changed. Conclusion: Thease findings showed that sitting continuously for longer than two hours decreases muscle strength, endurance, and flexibility. A flexed posture affects the muscle performance of the lumbar region and may result in problematic postures, such as a forward head position.

The Purpose of this study was ta investigate the change of bone density by Partial weight bearing and non-weight bearing exercise. Twelve female volunteers in good health (between 20 and 30 years of age) were studied as subjects. Subjects were divided into three groups; an experimental group 1(n =4 swimming group), group 2(n = 4 bicycle group) and control group=4. Before and after 11weeks(five times a week), the subjects were examined for change of bond density using a dual energy X-ray absorptiometry. The results were summarized as fellows T . There was increase in bone density of femoral neck in the group that swam but there was no difference in lumbar, femoral neck and femoral ward's triangle region (P<0.05) 2. There was increase in hone density of femoral ward's triangle in the group that swam but there was no difference in lumbar, femoral neck and femoral ward's triangle region(P<0.05) 3. After a aerobic exercise by partial weight bearing and non-weight bearing , there was no difference in the part of excessive muscle's exercise but there is the increase of the bone density in figures.

Degenerative lumbar spinal stenosis(DLSS) is a disease inducing low back pain, leg pain, convulsion, numbness, and neurogenic claudication from compression of nerve root. Intervertebra fixation was reported to increase the degenerative of neighbor region after treatment. Recently, a new surgical technique of inserting a fixator between interspinous processes has been introduced. The purpose of this study is to design of the interspinous process fixator with flexibility to complement the trouble of using fixator in DLSS. This study evaluated the existing fixator through the mechanical test and modified fixators using the finite element analysis(FEA). Displacement, stiffness and Von-Mises stress were found to have similar values to those obtained from the mechanical test and the FEA in the biomechanical loading condition. Effects of variation in length and thickness were investigated to design an optimal fixator.

Gold thread therapy (GTT) continuously stimulates acupoints and is used to treat chronic conditions/diseases such as chronic lumbar pain. During the procedure gold thread is embedded into the skin and although gold thread is medically pure, GTT is an irreversible treatment where there is limited evidence on its safety. Here, we report a case of a 79-year-old woman being treated for low back pain who developed side effects following moving cupping therapy at a site of GTT (performed in the 1970s). Adverse reactions causing radiating pain persisted more than at least 9 days following moving cupping therapy. The symptoms of pain were evaluated using the numerical rating scale, and changes in tenderness and the state of bruising was recorded. Low back pain improved but the radiating low leg pain did not improve. This case highlights the need for caution when performing moving cupping therapy where GTT has been previously performed.

The purpose of this study was to compare and analyze the differences in scan time, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) in the third lumbar vertebral region including the back fat, spinal cord, and cerebrospinal fluid using the mDixon, T2 TSE, and T2 spectral pre-saturation with inversion-recovery (SPIR) techniques. With the factors affecting the SNR fixed, the lumbar sagittal plane images of 30 adults were compared on mDixon, T2 TSE, and T2 SPIR imaging tests. The test times for mDixon, T2 TSE, and T2 SPIR were 115 seconds, 60 seconds, and 60 seconds, respectively. The mDixon T2 images showed higher SNR than the T2 TSE images at the third lumbar vertebral region (p<0.05), lower SNR in the back fat and cerebrospinal fluid (p<0.05) areas, and comparable SNR in the spinal cord (p>0.05). The CNR between the third lumbar vertebral area and back fat was higher in the mDixon T2 images, and the CNR of the cerebrospinal fluid and spinal cord images was higher in the T2 TSE images (p<0.05). The mDixon T2 FS images CNR was lower for the 3rd lumbar vertebral body region and back fat than the T2 SPIR images, and higher for the spinal cord and cerebrospinal fluid images (p<0.05). The CNR between the third lumbar body and back fat areas was higher in the mDixon T2 FS images (p<0.05), and there was no difference in the CNR in the images of the cerebrospinal fluid and the spinal cord (p>0.05). It is difficult to determine whether the mDixon technique is superior to the conventional T2 TSE and T2 SPIR techniques in terms of test time, SNR, and CNR. This study was confined to patients with simple lower back pain and was limited by controlled experimental conditions. Studies using clinically applied protocols are warranted in the future.

This paper was the study of a change in the body temperature of each region(Oral cavity, Axillary, Cubital, Popliteal, Inguinal region)and by time after appling hot(Hot Pack, Infra Red) and cold (Ice Pack, Cooling Pack) to lumbar region. The statistical measures were sampled through 16 senior students in dept. of Physiothrapy, Kim Cheun College and the period for this was from July 13, 1995 to July 20, 1995. There was an increse in the temperature of distal portion besides application area after hot application. The increse in the body temperature according to applied agents and time showed significance statistically(p<0.01, p<0.05). There was just a decrease in the temperature of distal portions besides application area after appling Ice Pack. Furthermore there was an increase in the body temperature after appling Cooling Towel. Therefore, during cold application the appling agents and time did not showed any significance statistically.

The purpose of this study is to analyze, durability of motor effort after finishing rehabilitation program and the influence from the isotonic lumbar region extension exercise after an operation according to the different operation way in invasive degrees. We selected randomly 80 patients who have no complication and musculoskeletal system diseases with finishing the 12 weeks' rehabilitation program after getting laser discectomy, but fail to conservative treatment, about Lumbar HNP, and divided into minimal invasive groups 38 and invasive groups 42 for study. As the results, in minimal invasive group, after finishing cure and 6 months later, the degree of hold muscle of women is much better than that of men. but in Invasive group, that of men is better than that of women, in case of women, the $0^{\circ}$ and $72^{\circ}$ in lumbar flexion angle have weaken or no improvement than before beginning exercise. and muscle force in $72^{\circ}$ in lumbar flexion angle increased to all men and women than before beginning exercise in Minimal invasive group. but in invasive group. it decreased. When analyze the lapsed time in Minimal invasive group, the groups who start the exercise within 3 months are better than the groups who start the exercise above 3 months after an operation the hold muscle degree all angles after finishing cure and 6 months later. Meanwhile, in invasive group, the groups who start the exercise within 3 months are better than the groups who start the exercise above 3 months after an operation about the hold muscle degree in 36-72 of lumbar flexion angle but 0-36 are not good after finishing cure and 6 months later. When analyze BMI in Minimal invasive group, the normal groups are better than the overweight groups about hold muscle degree in all angles after finishing cure and 6 months later.

Spinal epidural abscess, if especially caused by Brucellosis is a very rare disease which is usually a consequence of spondylodiscitis. The spinal column can be affected at any joint; however, the lumbar spine is the most common region, especially at the level of the L4-5 and L5-S1. The frequency of spinal involvement usually seen at the lumbar, thoracic and cervical spine respectively. As an occupational disease in farmers, veterinaries, butchers, laboratory staff and shepherds, brucellosis can also occur by direct contact to animals and infected materials or ingestion of raw cheese, milk or unpasteurized milk products. In this study, we presented two cases with cervical spinal epidural abscess caused by brucella melitensis, which was successfully treated by surgical approach. Initial treatment was combined with antibiotic therapy after the surgery for 3 months.

The common etiologies of pneumocephalus, presence of air in the intracranial cavity, are trauma and cranial surgery. Pneumocephalus after spinal surgery is an unusual postoperative complication. We report the case of a male 59-year-old man who developed a pneumacephalus after posterior lumbar surgery for spinal stenosis. Intraoperatively, a cerebrospinal fluid leak following a dural tear was noted and immediately repaired. The next day, the patient complained of headache and dizziness. Head and lumbar computed tomography scans revealed significant air in the frontal region, several cisterns, intraventricle, and extra-dural area in the spine canal. Symptoms were spontaneously resolved within 2 weeks with conservative management.

To study the effect of a disc creep on the cauda-equina occlusion, 3D-viscoelastic FE model including dura mater was developed. The model was analyzed according to various loading conditions and studied the contact between cauda-equina and nearby elements with time. With this contact the volume of the cauda-equina was changed. The contact and change of the volume were happened most highly in extension with time. By this result, it was concluded that the extension is the most fatal motion to cauda-equina in lumbar spine in all time region.
