머리 위 던지는 운동선수는 전방 관절낭의 이완과 강력한 동적 안정성이 요구되므로 조금이라도 흔들리면 쉽게 견관절 통증이 유발될 수 있다. 이러한 상태가 계속되면 견관절 조직의 강한 스트레스로 손상히 발생하게 된다. 따라서 정확한 재활 프로그램을 통하여 효과적인 결과를 얻을 수 있다. 상해가 발생한 던지기 선수에서 내회전의 소실, 외회전근과 견갑근육의 약화를 교정하여 주는 것에 중점을 두고 치료한다. 추가적으로 재활에 성공한 선수에서 던지기 동작의 생역학을 평가하고 오류를 교정하면서 지속적인 교육을 시행하여 재발을 방지하고 원할한 동작을 수행하게 한다.

The aim of this study was to determine the effect of a non-elastic fixation belt on the balance ability and fall prevention in elderly women. Elderly women experience reduced balance ability and an increased risk of falls due to a weakening of the surrounding sacroiliac joint and pelvic muscles during childbirth and menopause. On the other hand, specific studies are still needed. The subjects were allocated randomly to two groups: control (n=20) and experimental (n=20). The experimental group used a non-elastic fixation belt, whereas the control group had no fixation belt. The balance ability and the fall index were measured in all subjects using a balance measurement device, and the low abdominal muscle thickness was determined in the experimental group using ultrasound imaging for the exact application of the non-elastic fixation belt. The following statistical analysis was performed: an independent t-test for the general characteristics of the subjects, $2{\times}2$ analysis of variance with repeated measures for the balance and fall index score, and a paired t-test for the abdominal muscle thickness. The group ${\times}$ time interaction effect showed significant improvement in the General Stability Index (F1,38=47.24, p=0.001), Fourier Harmony Index (F1,38=88.83, p=0.001), Weight Distribution Index (F1,38=50.21, p=0.001), and Fall Index (F1,38=21.59, p=0.001). The thicknesses of the transverse abdominal (p=0.001) and internal oblique (p=0.001) muscles were increased significantly in the experimental group after using the non-elastic fixation belt. Overall, the application of a non-elastic fixation belt could be effective in improving the balance ability and fall prevention in elderly women.

The purpose of this study was to investigate the effects of cervical vertebral height and shoulder stabilization on anterior head posture in people with turtle neck. The subjects of this study consisted of normal and healthy people with 30 turtle necks. Subjects were randomly assigned to shoulder stabilization exercise and cervical vertebrae exercise (30 men, 15 men and 15 women, height: $168.67{\pm}6.51$, $22.33{\pm}8.27$, $65.03{\pm}11.98$, and $28.66{\pm}1.91$), In the experimental group, shoulder stabilization exercise and cervical spine exercise were performed for 4 weeks. Deep neck flexor, leavator scapular, upper trapezius, rhomboid, and lower trapezius showed significant differences in shoulder stabilization and cervical vertebrae before and after the experiment. As a result, the CVA value decreased significantly and the muscle activity value increased significantly when exercise and Mckenzie program were applied. These results show that exercise and Mckenzie programs have a positive effect on turtle neck improvement.

본 연구는 초기 편마비 환자의 손목에서 표면근전도 분석을 통해 근수축 개시 및 종료의 특성들을 알아보고, 임상적인 치료방법의 기초를 제안하고자 실시하였다. 연구대상자는 원주기독병원에 뇌졸중으로 입원한 환자 중 발병 후 3개월 미만인 13명과 원주시에 거주하는 대조군 7명이었다. 근수축 개시 및 종료의 지연은 표면근전도를 이용하여 손목굽힘근과 손목펴짐근에서 손목관절의 굽힘과 폄동작 시 3초의 근전도 신호음에 따라 가장 빠르고 강하게 최대 등척성 수축과 이완을 하여 신호를 수집하였다. 그 결과 편마비 환자의 환측은 건측과 대조군에 비해 손목관절 굽힘과 폄동작에서 근수축 개시및 종료가 유의하게 지연되었으며, 개시보다 종료가 더 유의하게 지연되었다. 따라서 초기 뇌졸중 환자의 근약화는 근육의 개시 및 종료의 반응시간 지연에 영향을 준다고 볼 수 있다. 앞으로 운동조절과 연관되어 기능적인 회복을 유도할 수 있는 근수축의 민첩성 훈련과 근섬유 동원의 효율성을 증진시키기 위한 치료방법들이 연구되어야 할 것이다.

Distal myopathy is a clinically and genetically heterogeneous group of degenerative diseases of the distal muscle. Glycogen storage disease type IXD (GSD9D) is a metabolic distal myopathy characterized by muscle deficiency of phosphorylase kinase, a key regulatory enzyme in glycogen metabolism. Affected individuals may develop muscle weakness, degeneration, and cramps, as well as abnormal muscle pain and stiffness after exercise. It has been reported that mutations in the PHKA1 gene which encodes the alpha subunit of muscle phosphorylase kinase cause GSD9D. In this study, we examined a Korean GSD9D family with a c.3314T>C (p.I1105T) mutation in the PHKA1 gene. This mutation has not been previously reported in any mutation database nor was it found in 500 healthy controls. The mutation region is well conserved in various other species, and in silico analysis predicts that it is likely to be pathogenic. To date, only seven mutations in the PHKA1 gene have been documented, and this is the first report of Korean GSD9D patients. This study also describes and compares the clinical symptoms and pathological conditions of previously reported cases and these Korean patients. We believe that our findings will be useful for the molecular diagnosis of GSD9D.

The purpose of this study was to compare and analyze the effects of exercise types on lower extremity muscle activity in stroke patients. For the purpose, the subjects of this study were classified into three groups such as therapeutic exercise group(n=7), elastic band group(n=7), and stretch reflex group(n=7). The three exercise programs were 5 times a week for 8 weeks. The stretch reflex group revealed higher in iliopsoas and biceps femoris %MVIC than the therapeutic exercise group and elastic band group, whereas elastic band group revealed lower in tibialis anterior %MVIC than therapeutic exercise group in the primary single-limb support. The stretch reflex group revealed higher in iliopsoas %MVIC than the therapeutic exercise group and elastic band group, whereas stretch reflex group revealed lower in medial gastrocnemius %MVIC than therapeutic exercise group in the secondary double support phase.

This study was intended to implement ankle joint dorsi flexion training against ankle muscule strength weakening that erodes stroke patients' gait performance to examine the effect of the training on stroke patients' plantar pressure and gait ability. In this study, 36 stroke patients diagnosed with stroke due to cerebral infarction or cerebral hemorrhage were divided to measure 10MWS which are stroke patients' gait variables maximum plantar pressure by area of the sole by collecting data using an F-scan system during gait. Given these results of the study, compared to other training groups, the ankle muscule strength reinforcing training group showed statistically significant increases of maximum plantar pressure in the great toe, the toe and the first metatasal areas too and thus it can be said that this training increases forward thrust during stroke patients' foot end taking off and positively affects stroke patients' ability to perform gait.

The motions used in throwing place tremendous stresses on the soft tissues about the player's shoulder. In order to throw successfully, the shoulder complex must be capable of excessive motion, while maintaining stability of the glenohumeral joint. Injuries to the throwing player can result from acute trauma, but more commonly can be a result of overuse injuries from the repetitive throwing activity. Inbalance in the muscles and soft tissue about the shoulder can result in an injury secondary to abnormal biomechanics of the glenohumeral complex. The preventive measure a throwing player can take in order to maintain a healthy throwing shoulder is to participate in a regular shoulder strengthening program. It is when the muscles about the shoulder become imbalanced, secondary to either injury or relative weakness, that instability and injury can occur. By understanding the pitching motion and the relative contribution of the muscles, the treating physician has a framework on which to build knowledge regarding physical findings and diagnosis of shoulder injuries in throwing players. Once a diagnosis is made. a successful treatment plan may be developed for the player, including both conservative and , at time surgical means.

수술시 근육 이완제로 사용되고 있는 metocurine iodide는 항생물질 투여환자, 중증 근무력중, 전해질 평형실조, 중증 신질환이 있는 환자 등에서는 작용이 증가되어서 상용량에서도 약화사고의 우려가 있어 규제가 필요한 약물이다. Metocurine iodide를 생체 시료중에서 분석하기 위해 rosebengal과 착제를 형성시켜 유기용매로 이온쌍 추출을 한 후, HPLC를 이용하여 rose bengal율 분석함으로써 metocurine iodide를 간접 정량하는 방법을 확립하였다. 이 방법은 뇨와 혈액증에 함유된 metocurine iodide를 0.09 - 9.10$\mu\textrm{g}$/m1농도에서 분석할 수 있었으며, 상관계수는 0.994 - 0.999로 양호한 직선성을 나타내었고, 동시 처방 약물의 영향은 거의 없었다. 뇨 및 혈액중 metocurine iodide의 검출 한계는 각각 0.8ng. 1.2ng (S =3)이었다.
