본 연구는 족소음경근의 구성요소에 대하여 문헌 해석과 인체의 층별 해부를 통하여 해부학적 관점에서 관찰해 보기 위하여 수행되었다. 그리하여 다음과 같은 결론을 얻을 수 있었다. 1. 본 연구 결과 족소음경근의 구성요소와 분석방법에 있어서 기존의 연구와 다소 차이를 보여준다. 2. 족소음경근의 경로와 병증 증상 등을 고려할 때 족소음경근은 근육, 근막, 인대, 그리고 관련 신경을 포함하는 포괄적 개념으로 보인다. 3. 족소음경근의 분포는 경락과 밀접한 관련성이 있으나 일치하지는 않는 것으로 보이며 특히 치골부위 이상의 부위에선 그러할 것으로 사료된다. 4. 이론적으로 MPS와 Anatomy train 같은 가설과는 약간의 차이가 있어 보이며 굳이 관련시켜 생각할 이유가 없다고 생각한다.

In human, ultrasonography is used to measure the pennation angle in various muscles to identify muscle functions such as force production, and to study alterations of the pennation angle during muscle contraction, hypertrophy, and atrophy. However, assessments of the pennation angle have not yet been conducted in dogs. This study aims to assess the normal pennation angle of the tibialis cranialis muscle in dogs using ultrasound and to detect changes in this angle in dogs with muscular atrophy. Sixty-eight healthy dogs were examined to establish normal values, while 12 ataxic and 12 lame dogs with suspected hindlimb muscle atrophy were also included. The pennation angle was measured using ultrasound at the midpoint between the proximal end of the tibia and the malleolus, measuring the angle between the muscle bundle and the deep aponeurosis. To confirm the significance between the 5 breeds and to identify a difference between normal and atrophied muscles, statistical analysis was conducted. The study found no significant difference in pennation angle between breeds, with mean values (± standard deviation) of 4.97° (± 1.88) in neutral, 7.25° (± 2.68) in flexion, and 3.31° (± 1.33) in extension positions. Decrease of the pennation angle was identified in muscle atrophy and the flexion position was determined to be the most appropriate for pennation angle measurement of tibialis cranialis muscle. We recommend considering the pennation angle as a valuable indicator of muscle health in dogs, as it demonstrates significant potential for diagnosing and monitoring muscular conditions.

The aim of this study was to assess whether the functional regeneration of a lyophilized autografted cartilage could be improved by implanting a vascularized muscle flap into the medullary canal of autografted proximal humerus. A hemijoint reconstruction using a lyophilized osteochondral autograft in proximal humerus was done in 4 rabbits for control, and combined with an vascularized intramedullary muscle flap in another 4 rabbits for the experimental group. Graft healing and the repair process of osteochondral graft were followed by serial radiographs and histologic changes for 9 weeks after experiments. Each two rabbits in control and in experimental group on 5th and 9th week after implantation of hemijoint were sacrified. The results were as follows: 1. All of control and experimental froups on 5th week united solidly on osteotomized site radiologically, but their articular cartilages were destroyed more seriously in the control than that in experimental group with muscle flap on 5th and 9th week after experiment... 2. Histochemically, the cartilage surface are completely destroyed and revealed with severe osteoarthritic changes on all cartilage layers in control, but cartilaginous erosions are mild to moderate and their arthritic changes are also mild with somewhat regeneration of chondrocytes on deep layers more prominetly on 9th week of the experimental group. 3. The amount of collagen and protenized matrix which was determined by Masson-Trichrome stain was markedly decreased that means the weakness of bony strength and low osteogenic potential in lyophilized cartilage. These results suggest that an intramedullary vascularized muscle flap can improve the functional results of lyophilized osteochondral autograft by providing both increased vascularity and populations of mesenchymal cells to initiate new bone formation on osteotomized site as well as the regeneration of deep layers in articular cartilage. In clinical relevances, this lyophilized hemijoint autograft combined with an intramedullary vascularized muscle pedicle graft might be used very effectively for the treatment of malignant long bone tumors to preserve the joint functions, all or partly, and so to replace it with the artificial joint after tumor excision and hemijoint autograft.

Background: This study aimed to evaluate the therapeutic results and safety of pectoralis major muscle turnover flaps in the treatment of mediastinitis after coronary artery bypass grafting (CABG) procedures. Methods: Data regarding 33 patients with post-CABG deep sternal wound infections (DSWIs) who underwent pectoralis major muscle turnover flap procedures in the Emam Reza and Ghaem Hospitals of Mashhad, Iran were reviewed in this study. For each patient, age, sex, hospital stay duration, remission, recurrence, and associated morbidity and mortality were evaluated. Results: Of the 2,447 CABG procedures that were carried out during the time period encompassed by our study, DSWIs occurred in 61 patients (2.5%). Of these 61 patients, 33 patients (nine females [27.3%] and 24 males [72.7%]) with an average age of $63{\pm}4.54$ years underwent pectoralis major muscle turnover flap placement. Symptoms of infection mainly occurred within the first 10 days after surgery (mean, $10.24{\pm}13.62days$). The most common risk factor for DSWIs was obesity (n=16, 48.4%) followed by diabetes mellitus (n=13, 39.4%). Bilateral and unilateral pectoralis major muscle turnover flaps were performed in 20 patients (60.6%) and 13 patients (39.4%), respectively. Complete remission was achieved in 25 patients (75.7%), with no recurrence in the follow-up period. Four patients (12.1%) needed reoperation. The mean hospitalization time was $11.69{\pm}6.516days$. Four patients (12.1%) died during the course of the study: three due to the postoperative complication of respiratory failure and one due to pulmonary thromboembolism. Conclusion: Pectoralis major muscle turnover flaps are an optimal technique in the treatment of post-CABG mediastinitis. In addition to leading to favorable therapeutic results, this flap is associated with minimal morbidity and mortality, as well as a short hospitalization time.

Bovine spastic paresis (BSP) is a neuromuscular disorder characterized by hypertension and stiffness of hindlimb. Two Korean native cattle (Hanwoo) calves developed BSP or BSP-like symptoms, and a tenotomy of superficial tendon of medial head and deep tendon of lateral head of gastrocnemius muscle was performed for treatment. A cast was applied postoperatively to prevent muscle rupture and was removed three weeks later. The prognosis was evaluated at 3 weeks, 6 and 18 months postoperatively. Neither calf showed any other postoperative sequelae. This is the first case study to report the diagnosis, treatment, and prognosis of BSP in Hanwoo.

Purpose : The purpose of this study was conducted to find out observation at gait analysis of the stroke patient with proprioceptive neuromuscular facilitation(PNF) concept. Methods : This is a literature study with books, seminar note and international PNF course book. Results : Stroke patient gait was poor initial contact by weakness of tibialis anterior or weakness of contralateral plantar flexor, poor loading response by loss of deep sensation, poor mid stance by loss of deep sensation, weakness of tibialis anterior and weakness of plantar flexors eccentric control, poor terminal stance, pre-swing, initial swing by loss of deep sensation and stiffness fo deep toe flexors. Conclusion : Stroke patient gait determine on loss of mobility, pain, fear, trunk muscle weakness, loss of coordination, loss of deep sensation, neglect and apraxia. Therefore observational gait analysis of the stroke patient focus on gait cycle and take out hypotheses from the gait cycle. These hypotheses have to define accept or not by parameters. Treatment plan made with the hypotheses.

Purpose: The purpose of this study was to identify the effects of an exercise program on muscle strength, Activities of Daily Living (ADL), health perception, and depression among post-stroke elders. Methods: Nonequivalent control group design with pretest and posttest was used. A total of 23 post-stroke elders who met inclusion criteria were recruited. Muscle strength in upper and lower extremities, ADL, health perception, and self-rated symptoms of depression were measured. The exercise program consisted of deep breathing, range of motion, and muscle strengthening exercises using Thera-band, 30~40 min/day, three days a week, for 12 weeks. Results: Muscle strength of right shoulder (U=11.50, p=.001), right leg (U=13.50, p=.002), and health perception (U=24.00, p=.010) in the experimental group was significantly higher compared to the control group at 12 weeks of post-intervention. Depression scores were significantly lower in the experimental group compared to the control group at 6 weeks (U=28.00, p=.021), at 12 weeks (U=22.00, p=.006) of an exercise program. Conclusion: By applying this program, post-stroke elders showed increases in muscle strength and a decrease in depression as well as improvement of health perception. Further study is needed to verify the effects of the exercise program on cardiovascular physiologic variables through long-term follow-up.

Purpose: The aim of the study was to investigate neck posture, range of motion, muscle endurance and self-report of pain and disability in smartphone users. Methods: Seventy-eight university student volunteers, aged between 18 and 30 years (mean age 23.2), were assessed for: a head-neck posture by measuring cranial vertical angle, neck range of motions using cervical range of motion device, and a deep neck flexor endurance using a stabilizer. Finally, subjects were asked about their neck pain and completed disability questionnaires, ie, Short Form McGill Pain Questionnaire, Neck Disability Index, and World Health Organization Disability Assessment Schedule 2.0. Results: Thirty-eight subjects experienced recurrent neck pain with/without upper limb pain (neck pain group) and 40 reported no current neck pain with/without upper limb pain (no neck pain group). Differences were found between groups on pain and disability questionnaires. Subjects with neck pain had significantly higher disability scores than those of no neck pain group. However, there were no differences observed between groups in a head-neck posture, neck range of motions, and deep neck muscle endurance time. The smartphone usage time was negatively correlated with neck pain intensity and disability score whereas it had positive relationship with flexibility and posture. Conclusion: Group differences were observed as lower capacity not only for neck specific daily activities but for general functioning in daily routine when the neck pain and no neck pain groups were compared. Therefore, functioning in daily activities should be investigated as prevention for further developing neck pain in smartphone users.

Background: Neck pain is a common problem in the general population and second only to low back pain in musculoskeletal problems. The aim of this study is to compare three different types of exercise training in patients with chronic neck pain. Methods: This study was conducted on 45 patients with neck pain. Patients were divided into 3 groups: Group 1 (conventional treatment), Group 2 (conventional treatment plus deep cervical flexor training), and Group 3 (conventional treatment plus stabilization of the neck and core region). The exercise programs were applied for four weeks, three days a week. The demographic data, pain intensity (verbal numeric pain scale), posture (Reedco's posture scale), cervical range of motion ([ROM] goniometer), and disability (Neck Disability Index [NDI]) were evaluated. Results: In all groups, a significant improvement was found in terms of pain, posture, ROM, and NDI values in all groups (P < 0.001). Between the groups, analyses showed that the pain and posture improved more in Group 3, while the ROM and NDI improved more in Group 2. Conclusions: In addition to conventional treatment, applying core stabilization exercises or deep cervical flexor muscle training to patients with neck pain may be more effective in reducing pain and disability and increasing ROM than conventional treatment alone.
