Lumbar braces, cast jackets and lumbar corsets are commonly prescribed for the relief of low back pain or the prevention of instability of lumbar or lumbosacral vertebrae. These devices have been presumed to achive their effect by (1) decreasing movement at the involved intervertebral joints, (2) shifting a portion of the load from the spine to the rest of the trunk by compressing the abdomen, (3) decreasing lumbar lordosis and therefore, mechanical stress on the spine and (4) providing sufficient support to allow relaxation of the muscles of the trunk. But it is doubtful that lumbar braces or corsets significantly decrease movement between lumbar vertebrae. To maintain the stability of the lumbar and lumbosacral spine, abdominal muscles and intrinsic muscles of the back play an important role. When these muscles weaken the lumbar lordosis becomes exaggerated possibly bringing about degenerative changes in the articular processes and approximation of the spinous processes. In severe cases results in the so-called kissing spine which causes low back pain. The pain may be relieved by use of lumbo-sacral corsets or knight braces, which diminish lordosis. However, there has been no scientific report on adequate types of braces, duration of use or muscle weakness resulting from its use as yet. The prupose of this study is to provide a theoretical braces for, planning adequate prevention and early treatment, so that labour loss from retirement or change of job due to low back pain could be minimized, permitting early return to employment and resumption of activities of daily living. In other words, this study concentrates on the indications for use and selection of which will produce optimum results in the treatment of patients with low back pain. The EMG was taken immediately after admission, and after 3 weeks of bed rest accompanied by pelvic traction with or without heating, and also it was taken after 6 weeks of use of brace. The results obtained from this study were as follows; 1. After bed rest the EMG activities were increased in back muscles, such as longissimus dorsi, multifidus and iliocostalis lumborum and in abdominal muscles of internus abdominis while decreased in rectus abdominis. 2. There has been no significant change after use of corset in acute cases while the muscle activities. were increased after use of lumbar corset in chronic cases. 3. Rectus abdominis was most senstively influenced by bed rest or use of brace both in acute and chronic cases. And it was the last to recover probably because it does not contract in ordinary alow walking. 4. Knight brace was considered to be preferable to lumbar corset in acute cases with evidence of weakness in abdominal muscles by EMG. 5. There was no difference between bed rest and use of brace in patients who had radiculopathy with functional difficulties or not.

Measurement of motor nerve conduction velocity(MNCV) of the median and peroneal nerves was performed in 79 normal fullterm newborn infants and children up through the age of 329 weeks. They were divided into eight groups by age. The following study was undertaken to obtain the mean +/- S.D. and the regression equation of Y (MNCV) on X (age). The MNCV values of each group were compared with those of normal adults.

The objective of this study was to investigate the influence of the hip flexion upon parameters that are indicators of spinal mobility. These parameters include intervertebral disc angle and lumbar curvature by measurement of the radiography in twenty eight healthy men. The state of knowledge of how these parameters relate to lumbar mobility have resolved. The results of the parameters showed negligible changes in relation to the mobility of lumbar spine according to angle of hip flexion except at L4-L5 intervertebral disc angle and lumbar curvature (p< 0.05). This results of study confirms that hip joint movement therapy can be applied to these norms in patient management in supine position of for the stable spinal injuries in the upper lumbar region during early phase.

Orthotic technology has developed rapidly in recent decades m western countries. Korea has been confronted with the problems of purchasing the appropriate orthotic materials, training of orthotists and financial expense. The introduction of new materials and lamination technology for orthotic appliance will enable such problems to be solved. Fiberglass reinforced plastic (FRP), which was laminated with Korean made plastic resins and fiberglass, was superior to the mechanical properties of other plastic materials, such as acrylic, polypropylene and thermoplast. Lamination of the orthotic devices with FRP was introduced and it should be technically possible for an orthotist in a small workshop or a member of the house staff of a hospital to make an appliance on the premises.

OBJECTIVE: The purpose of this study was to investigate the effects of video feedback training for the parents of autistic spectrum disorder children. METHOD: Ten Autistic spectrum disorder children and their mothers participated in this training. Twenty minutes play times were videotaped including free play time and chosen play time. After one session, watching videotape, the researcher analyzed the relation of the children and their mother and had a feedback training with the mother of child. RESULTS: The child's responses to the mother's start actions had significant differences (p<0.05). The language responses of children increased in the organized environment of chosen play. Language responses increased but negative actions and no responses reduced when mother encouraged child centered play rather than mother engaged in children's play directly. In log sector model, mother's responses according to the play type had meaningless difference (p0.05). But in division analysis mother's responses to child's start action had meaningful difference in pre/post treatment and play type. CONCLUSION: The effects of video feedback training of autistic spectrum disorder children's parents were positive. Through this investigation the interaction and the communication with autistic spectrum disorder children and their parents are influenced positively.
