Nerve torsion is a rare condition that causes sensory abnormalities and decreased muscle strength due to a nerve-twisting phenomenon in the peripheral nerves. To date, the progression of the condition from its cause to diagnosis and treatment has not been established. The authors report three cases of good results from the treatment of nerve torsion in the anterior interosseous and radial nerves with epineurotomy and neurolysis.

Selective fascicular involvement of the median nerve trunk above the elbow leading to anterior interosseous nerve (AIN) syndrome is a rare form of peripheral neuropathy. This condition has recently garnered increased attention within the medical community owing to advancements in imaging techniques and a growing number of reported cases. In this article, we explore the topographical anatomy of the median nerve trunk and the clinical features associated with AIN palsy. Our focus extends to unique manifestations captured through MRI and ultrasonography (US) studies, highlighting noteworthy findings, such as nerve fascicle swelling, incomplete constrictions, hourglass-like constrictions, and torsions, particularly in the posterior/posteromedial region of the median nerve. Surgical observations have further enhanced the understanding of this complex neuropathic condition. High-resolution MRI not only reveals denervation changes in the AIN and median nerve territories but also illuminates these alterations without the presence of compressing structures. The pivotal roles of high-resolution MRI and US in diagnosing this condition and guiding the formulation of an optimal treatment strategy are emphasized.

Aging has been recognized as the primary cause of disc degeneration. A biomechanical characteristics of disc degeneration has been demonstrated that intradiscal pressure is reduced. With the increasing population of elderly people, disc degeneration and associated problems of nerve entrapment are becoming more prevalent. Presently, research on reduced intradiscal pressure associated with degeneration is insufficient. In this study. we used the Finite Element Method (FEM) of computerized simulations to investigate the effects of variation in intradiscal pressure on mechanical behaviours of L4-5 intervertebral disc degeneration. Degeneration was classified using four grades based on initial intradiscal pressure; Normal (135 kPa), mild(107 kPa), moderate (47 kPa) and severe (15 kPa). The predicted results f3r bending loads were as follows; 1 . Range of motion increased progressively with severity of degeneration with flexion and lateral bending moments, but decreased with extension moments. 2. Discal bulging of posterolateral aspect was larger in lateral bending and extension moment. But bulging was increased with severity of degeneration in lateral bending and torsion(same side).3. The rate of increasing intradiscal pressure was decreased in all bending motions with severity of degeneration. In conclusion, lateral bending and extension moment yield greatest bulging in severe degeneration. In torsion, although bending load produces disc bulging, disc bulging was associated more strongly with severity of degeneration than increasing torsional moments. Clinical Implications: Discal bulging may produce nerve root impingement and irritation. The effect of loading and posture on the varying degrees of disc degeneration has important implications especially in the elderly. In the presence of disc degeneration, avoidance of end range postures, especially extension and lateral bending may help reduce discal bulging and in turn, nerve entrapment.

Purpose : Dysmenorrhea can be caused by misalignment of the pelvis. Since pilates stabilization exercise is a methods that affects pelvic alignment by inducing contraction of abdominal muscles, the purpose of this study is to determine whether dysmenorrhea is reduced when pilates stabilization exercise is applied. Methods : 47 dysmenorrhea patients were randomly divided into experimental (n=23) and control (n=24) groups. The experimental group performed pilates stabilization exercise three times a week for 12 weeks, and the control group did not perform any intervention. Abdominal muscle thickness, lumbar pelvic alignment, and dysmenorrhea were measured before intervention, 6 weeks, and 12 weeks after intervention to determine the mean change over time and the effect of group and factor interactions (repeated measured ANOVA and contrast test for each period). Results : In the experimental group, the thickness of the transverse abdominis, internal oblique, and external oblique muscles were increased significantly by group and period (p<.05). The pelvic torsion, lordosis and dysmenorrhea were also significantly decreased by group and period. But the control group did not change significantly in any of the variables. Conclusion : Applying pilates stabilization exercise to women with dysmenorrhea may be an effective intervention that contributes to relieving dysmenorrhea by correcting the stability and alignment of the lumbar pelvis.

Objectives : It is important to develop a new Chuna manual therapy as a representative of Chuna manual therapy technique at the time of KSCMM's (Korean Society of Chuna manual medicine) joining a $F{\acute{e}}d{\acute{e}}ration$ Internationale de $M{\acute{e}}decine$ Manuelle (FIMM). Therefore, Sunu manual therapy (SMT) will be introduced as a purely new Chuna manual therapy. Main subject : Sunu manual therapy (SMT) was discovered about two decade ago by a Korean Medicine doctor who wanted to develop a new manual therapy to treat a internal disease. It is very important to make the best use of four powers such as a compression force, a torsion force, a bending force, a tension force using a resonance principle and to experience a feeling of spine axis. SMT is different from Chiropractic technique and Osteopathy technique, in that SMT could treat so many disease using only one technique, but other manual therapy could utilize so many technique to treat only one disease. Discussion : Because SMT utilize a power of a moving in silience, it will take several years to totally master a SMT which will make a patient and a doctor experience a feeling of spine axis. As a feeling of spine axis is deeper, a nerve could be excited and treated by a SMT. Also as a feeling of spine axis is shallower, a muscle could be excied and treated by a SMT. Conclusions : SMT could be classed as a craniosacral chuna therapy or visceral chuna therapy to treat a internal disease considering SMT's action and purpose.
