Avulsion rupture of the flexor digitorum profundus tendon at the distal phalanx is a rare injury. It usually occurs during extension of the DIP joint, while the flexor digitorum profundus tendon is contracted, or when strong extension force is applied, to the distal phalanx. We experienced a patient, combat policeman who had avulsion rupture of flexor digitorum profundus tendon at the distal phalanx after 2 days of combat exercise. Here, we would like to report unusual case of rare tendon injury with studies from other papers.

This research is first to analyze an electomygram reaction of the lower limbs among the muscles used during a back-round kicking of Taekwondo, second to analyze the relationship between the muscles of the kicking limb and those of the supporting limb, third to compare EMG activity of expert with novice. Measured muscles are as follows; rectus fermoris which control flexion and stretching of femora and knee joints, vastus medialis and vastus lateralis, which control flexion and stretching of legs, and biceps fermoris, which control stretching of femora, bending of knee joints and abduction of the crus. The electomygram reaction of all these selected muscles were analyzed. Three kicks were performed, and electomygram of each of kicks were measured. Then, electomygram reaction of the best kick was used for electomygram analysis.

Purpose : To identify the effects of flexion-extension of stretching on the functional improvement of patients with neck myofascial pain syndrome. Methods : the present research investigated 30 patients with neck myofascial syndrome, dividing them into a group doing flexion-extension of stretching. This study examined degree of recovery from neck pain by comparing their neck myofascial pain syndrome before and after the treatment, and compared to find difference in the degree of recovery from myofascial pain syndrome. Results : The results are as follows. For the flexion of stretching, 1. For the visual analogue scale (VAS) decreased significantly for six weeks treatment, 2. For the flexion decreased significantly for six weeks treatment. and the range of motion of cervical vertebrae increased significantly(p>.05). 3. For Stretching, range of motion left rotation indicated significant difference after pre test and after two week but no significant difference after six week. 4. For the left rotation decreased significantly for six weeks treatment. and the range of motion of cervical vertebrae increased significantly(p>.05). 5. For the right rotation decreased significantly for six weeks treatment. and the range of motion of cervical vertebrae increased significantly(p>.05). Conclusion : This study suggest that flexion-extension of stretching have an effect on the functional improvement of patients with neck myofascial pain syndrome.

Injection laryngoplasty is simple and useful procedure in patient with vocal cord paralysis even under local anesthesia. For approaching vocal cord level, flexibility of neck mobility is required to operate injection laryngoplasty but it is relatively difficult to approach vocal cord in patient who has cervical fixations. Laryngeal mask airway (LMA) can be helpful:We use a LMA (I-gel$^{TM}$) during intubation without neck extension on flat supine position under general anesthesia and have a good operation filed. LMA with swivel connector give surgeons better surgical vision and make insertion of fibroscope easily during operation. Hyaluronic acid injection was done use needle (25 G, 5 cm) via percutaneous cricothyroid space : This procedure can be useful method for patients who suffer from not only weak voice but also dysphagia and aspiration high vagal palsy patient after spine surgery or uncooperative with awake injection laryngoplasty.

The purpose of this study was to describe the biomechanical characteristics of stroke patients. These characteristics were obtained during walking on a Zebris system, cinematography system and EMG system. Seven female stroke patients participated in this study. The magnitude of the profiles (joint peak angle, joint peak moments, foot pressure COP, EMG data) correlated with rehabilitation training duration using t-test. The significance level selected for this study was p<0.05, t-test. Joint analysis identified significant differences in hip joint peak angle and hip joint peak moment. Foot pressure verified significant differences in gait line length of COP. The EMG signal proved significant differences in rectus femoris and vastus lateralis.

이 연구의 목적은 노인들 중, 넘어지는 사람들(fallers)과 안 넘어지는 사람들(nonfallers)의 경부, 체간, 하지의 관절가동범위를 측정하여 비교하는 것이다. 본 연구대상은 남자 6명, 여자 22명, 나이 65세에서 88세의 노인으로 독립적으로 활동할 수 있는 사람들을 두 개의 집단으로 한 사람씩 면접을 통해 분류하였다. 대상자 선정 이전 일년 동안 한번 이상 넘어진 경험이 있는 사람들을 넘어진 사람들로 규정, 그리고 넘어진 경험이 없는 사람들을 안 넘어진 사람들로 정의하였다. 관절가동범위는 각도기로 측정하였고 미국 정형외과 학회(American Academy of Orthopaedic Surgeons)의 표준화된 가동 범위 측정방법을 사용하였다. 넘어진 사람들과 안 넘어진 사람들의 연구 결과의 차이를 알아보기 위하여 양측 독립성 t-검정을 사용했다. 연구결과, 넘어진 사람들과 안 넘어진 사람들간의 관절가동범위 중 흉요부의 굴곡, 신전, 우측굴곡, 좌측굴곡, 그리고 우측회전과 좌측회전, 고관절부의 신전, 내전, 외측회전과 내측회전, 그리고 족관절의 배굴에서 유의한 차이가 있었다. 이와 같은 결과는 체간, 고관절부 그리고 발목의 유연성이 노인들의 균형을 유지하는데 영향을 준다고 말할 수 있다.

In this paper, we discuss the abnormalities of flexion and extension in elbow disease in general. Flexion and extension represent arm flexion and extension while being set to 90 degrees. In this case, the angle of the arm is remarkably small, or the pain is accompanied by an abnormality in the elbow. We tested 100 elbow flexions and extensions at the age of 50 and calculated the number of people in each case. After that, patients with abnormalities in flexion and extension were classified and their treatment methods were presented. In this paper, we have developed a system for treating musculoskeletal disorders.

Case of patients with weakness in cardiopulmonary system, other ambulatory function is normal, but oxygen supply function is problem. So they need reduce energy consumption for gait by assistance system. In this study, we designed and developed walking assistant device which helps flexion and extension of hip joint for cardiopulmonary patients. There are two motors, each at the left and right side of pelvis, providing torque to the hip joint. The target angle of the flexion and extension in the hip joint is set according to the normal gait. As a result, reduction of energy consumption was 14.8% by gait assistive device.

A checkrein deformity can occur after a distal tibiofibular fracture. Usually, a checkrein deformity due to a dysfunction of the extensor hallucis longus muscle is rarer than that of the flexor hallucis longus. Only a few related studies have been reported. The authors encountered an extensor hallucis longus checkrein deformity due to extensor retinaculum syndrome while managing a triplane fracture. In magnetic resonance imaging, an increase in the heterogeneous signal was observed on the T2-weighted images suggesting muscle necrosis or ischemic changes in a part of the extensor hallucis muscle. Postoperative great toe motor weakness, unintentional movement, sensory changes, and weakness improved spontaneously during the follow-up.

목적: 농촌 지역사회 기반의 허리 근력 강화 운동 프로그램이 운동과 허리 건강에 대한 개인의 태도 및 믿음에 미치는 효과를 평가하고자 하였다. 방법: 강원도 지역 네 개의 농촌 마을에서 가벼운 허리 통증이 있는 79명의 여성 자원자(42-76세)들을 운동군(n=40)과 대조군(n=39)으로 마을단위로 배정하였다. 운동군에서는 지역사회 기반의 허리강화 운동 프로그램(주당 3회, 8주간)이 시행되었고 대조군에는 일반적인 건강 관리에 대한 강의가 제공되었다. 등척성 허리 신전 근력과 허리 통증 관련 장애, 운동에 대한 태도, 허리 질환에 대한 위협인지, 운동의 자기 효능감을 중재전과 중재후 1, 2개월째 측정하였다. 결과: 운동군에서 2개월후 허리 신전근력은 뚜렷이 증가하였으며 허리 통증 관련 장애도 유의미하게 감소하였다. 운동에 대한 태도와 허리 질환에 대한 위협 인지는 운동군에서 증가하였으나 대조군에서는 변화가 없었다. 운동의 자기효능감은 양군에서 같이 증가하였으나 운동군에서 그 정도가 더 뚜렷했다. 결론: 농촌 지역 여성들을 대상으로 한 허리 근력 강화 운동 프로그램은 허리 통증으로 인한 장애를 감소시켰고 운동의 효과에 대한 태도와 믿음을 변화시켰다.
