This study aimed to compare functional recovery after rehabilitation exercise between isolated PCL reconstruction and combined PLC reconstruction. Patients were divided into two groups: those who had isolated PCL reconstruction (n = 16) and those who had combined PLC reconstruction (n = 16). We assessed knee joint ligament laxity, subjective questionnaires, and isokinetic muscle function before, after 12, and 24 weeks of a rehabilitation exercise program. In both groups, there were significant differences in knee joint laxity (p = 0.048), IKDC subject score (p < 0.001), Lysholm knee (p < 0.001), Tegner activity scale (p = 0.027), and isokinetic muscle deficit (p = 0.040) by estimated period. However, no significant difference between groups was observed (p > 0.05). These results suggest that rehabilitation exercise after isolated PCL and combined PLC reconstruction influenced structural, subjective, functional recovery positively.

This paper uses variables following as : to follow me well(0-9), it takes a lot of time to make a decision (0-9), lethargy(0-9) during physical activity in the exercise learning program of the children in the marginalized class. This paper classifies 'gender', 'physical education classroom', and 'upper, middle and lower' of age, and observe changes in ego-resiliency and self-control through sports rehabilitation therapy to find out changes in mental health. To achieve this, the data acquired was merged and the characteristics of large and small numbers were removed using the Label encoder and One-hot encoding. Then, to evaluate the performance by applying each algorithm of MLP, SVM, Dicesion tree, RNN, and LSTM, the train and test data were divided by 75% and 25%, and then the algorithm was learned with train data and the accuracy of the algorithm was measured with the Test data. As a result of the measurement, LSTM was the most effective in sex, MLP and LSTM in physical education classroom, and SVM was the most effective in age.

Background: Physical therapy (PT) plays an important role in the recovery of function following anatomic total shoulder arthroplasty (aTSA). While several PT protocols have been published for these patients, there is no standardized protocol for aTSA rehabilitation. This lack of standardization may lead to confusion between patients and physicians, possibly resulting in suboptimal outcomes. This study examines how PT protocols provided by academic orthopedic surgery programs vary regarding therapeutic goals and activities following aTSA. Methods: PT protocols for aTSA available online from the Accreditation Council for Graduate Medical Education accredited orthopedic surgery programs were included for review. Each protocol was analyzed to evaluate it for differences in recommendation of length of immobilization, range of motion (ROM) goals, start time for and progression of therapeutic exercises, and timing for return to functional activity. Results: Of 175 accredited programs, 25 (14.2%) had protocols publicly available, programs (92%) recommended sling immobilization outside of therapy for an average of 4.4±2.0 weeks. Most protocols gave recommendations on starting active forward flexion (24 protocols, range 1-7 weeks), external rotation (22 protocols, range 1-7 weeks), and internal rotation (18 protocols, range 4-7 weeks). Full passive ROM was recommended at 10.8±5.7 weeks, and active ROM was 13.3±3.9 weeks, on average. ROM goals were inconsistent among protocols, with significant variations in recommended ROM and resistance exercise start times. Only 13 protocols (52%) gave recommendations on resuming recreational activities (mean, 17.4±4.4 weeks). Conclusions: Publicly available PT protocols for aTSA rehabilitation are highly variable. Level of evidence: IV.

Based on related studies on 'disability sports,' 'sports for all,' and 'rehabilitation sports,' this study collected the results of a survey on the disabled, who are the actual users of rehabilitation sports services. It analyzed the need for rehabilitation sports services. The requirements of persons with disabilities were extracted, and the extracted contents were presented as inductive content analysis. The researcher's preconceptions and subjective judgments were to be excluded as much as possible. Based on studies related to "Disability sports," "Sports for all for disability," and "Rehabilitation sports," conducted in Korea, a study that included the results of the survey on disabled people was selected. This study's results were categorized into eight categories (perception of sports activities, programs, instructors, facilities, accessibility, cost/support/financial resources, and others) for people with disabilities.

Forward Head Posture (FHP) involves the anterior positioning of the head relative to the shoulders, often associated with muscular imbalances. It is known that individuals with FHP experience shortening of craniocervical extensors and cervical flexors. However, contrary to the understanding of flexion in the craniocervical extension subaxial region, a study has reported flexion in the craniovertebral spinal vertebrae among individuals with FHP. The aim of this study was to examine the consistency of biomechanical study results conducted for FHP. The relevant studies were investigated in PubMed and Google Scholar databases using the keywords "forward head posture OR cervical sagittal alignment OR cervical spine AND biomechanics OR kinetic analysis OR kinematic analysis." During the research selection process, only nine studies relevant to the purpose of our study were identified. Out of these nine studies, four conducted kinematic analysis related to FHP formation, while six conducted kinetic analysis. During the comparison of these studies, five inconsistencies were identified. Biomechanical studies on FHP reveal conflicting findings, suggesting potential variability in the biomechanics of FHP formation across individuals. However, drawing definitive conclusions requires further exploration through additional biomechanical investigations on FHP in the future.

[Purpose] This study evaluated the anti-atopic dermatitis (AD) properties of Cordyceps militaris (CM) aqueous extract in keratinocytes in vitro and in vivo. We investigated the nutraceutical composition of the CM extract, including its protein, carbohydrate, and selected phytochemical content. [Methods] The expression of pathogenic cytokines in keratinocytes was assayed using an in vitro model. The CM extract downregulated extracellular signalregulated kinase 1/2 (ERK1/2) and p38 kinase expression in TNFα/IFNγ-stimulated HaCaT cells. We also established an in vivo AD model by repeatedly exposing the ears of mice to local Dermatophagoides farinae extract (DFE; house dust mite extract) and 2,4-dinitrochlorobenzene (DNCB). The epidermal and dermal ear thickness, mast cell infiltration, and serum immunoglobulin levels were measured following a 4-week oral administration of the CM extract. [Results] Histopathological examination showed reduced epidermal/dermal thickness and mast cell infiltration in mouse ears. The CM extract also suppressed serum immunoglobulin levels and gene expression of T helper (Th)1/Th2 cytokines in mouse ear tissue. [Conclusion] These results suggest that the CM extract may be useful for the treatment of AD-like skin lesions.

The purpose of this study is to highlight nationalistic characteristics of private school's military gymnastic education in early modern Korea. so deal with the process of Military Gymnastics between 1895, when modern public school in Korea was first established, and 1910, when Korea was deprived of its sovereignty by japan. The following conclusions have been drawn from the study. The main idea of military style-gymnastics came from the consciousness of crisis caused by threat of the Japanese aggression. At that time, Korean realized the importance of physical education by this crisis consciousness. And Korean people was interested in physical education that they could not think of in traditional education. This Gymnastic class was much more like military training and has a patriotic character.

Breast cancer is the most common malignancy in women, and lymphedema is one of the most common postoperative complications of breast surgery. Exercises are usually prescribed to prevent this occurrence. On the other hand, conflicting results regarding the effects and timing of such exercises have been reported. This study reviewed systematically the contemporary literature, peer-reviewed publications, and web sites of professional organizations that examined exercise for lymphedema prevention or therapy to determine the effects of exercise on lymphedema providing the best evidence for the treatment of patients. Exercise or training groups have strategies that appear to reduce the development of secondary lymphedema and altering its progression compared to the control group. Advances in cancer treatment, cancer and exercise research, and lymphedema management require physicians to have a basic understanding of the current evidence to provide the appropriate patient education and specialist referral.
