Purpose : We aimed to investigate the effect of cranio-cervical flexion exercises(CCFE) with visual feedback(VF) on the muscle activity of the upper trapezius in forward head posture (FHP) and whether deficits in proprioception affect the changes in muscle activity. Methods : Twenty subjects with FHP were assigned to one of 2 groups according to deficits in proprioception. The muscle activity of the upper trapezius during arm movement under three exercise conditions (resting, CCFE, and VF + CCFE). Repeated-measures analysis of variance was used to compare differences in muscle activity according to the exercise conditions between the groups and to analyze the interactions between groups and conditions. Results : Significant differences were observed in muscle activity according to the exercise condition (p<.05), with no significant differences between the groups. The muscle activity of the upper trapezius was significantly different between the resting and VF +CCFE conditions (p<.05), with no significant difference between the resting and CCFE conditions (p>.05). Conclusion : The results of this study showed that the CCFE combined with VF are an effective intervention for FHP to train deep muscles selectively. In addition, the loss of proprioceptive sensation is not related to changes in muscle activity during exercises.

PURPOSE: This study examined the influence of treadmill exercise with initial pain control using transcutaneous electrical nerve stimulation (TENS) on induced pain of knee osteoarthritis in rats. METHODS: Thirty adult male Sprague - Dawley rats were divided randomly into the TENS Group (TG, n = 10), Treadmill Exercise Group (TEG, n = 10), and Treadmill with TENS Group (TTG, n = 10). In the TG, TENS was performed for 20 min per day for two weeks with a TENS program at the knee joint. The TEG performed treadmill exercise 15 m/min for 20 min per day for two weeks. The TTG performed initial pain control by TENS program during the 1st ~ 3rd days, and treadmill exercise was performed using the TEG methods from the 4th day. The lumbar spine was extracted and processed using western blot analysis to evaluate pain (c-fos expression). RESULTS: The results showed that c-fos expression was decreased significantly in all groups after each intervention (p < .05). In particular, TTG produced the most significant decrease compared to the other groups. CONCLUSION: These results suggest that treadmill exercise with initial pain control using TENS is a suitable method for relieving pain in knee osteoarthritis.

Objective: The purpose of this studyaimed to investigate the effects of scapular stabilization training using the different exercise prop for impingement syndrome of factory workers. Design: A randomized controlled trial Methods: Twenty shoulder impingement syndrome subjects were randomly divided into two groups of ten subjects each. Inclusion criteria was presence of positive sign in at least two of Neer test, Hawkins test, Yocum test, Jobe test and Speeds test. Andexclusion criteria, those with surgical history of rotator cuff, those with disease in upper limb other than shoulder impingement syndrome, those who took anti-inflammatory drugs over the past 12 months were excluded from the sample. One group was performed scapula stabilization exercise using elastic bands, while dumbbell group performed the exercise using dumbbell. Both groups performed the exercise after applying the general physical therapy. After applying five days a week for a total of six weeks, range of motion of shoulder joint, muscle strength and pain and function level were evaluated. Results: After the intervention, in both groups, all dependent variables at the 6-week post-test significantly improved compared with the pre-test (p<0.05). In addition, elastic band exercise group showed a significant differences in SPADI function score and SPADI total score compared to the dumbbell group(p<0.05). Conclusions: The elastic band training may be effective methodology using low-to-moderate intensity resistance for SPADI scores.

Fat embolism syndrome is a rare but alarming, life-threatening clinical condition attributed to fat emboli entering the circulation. It usually occurs as a complication of long-bone fractures and joint reconstruction surgery. Neurological manifestations usually occur 12 to 72 hours after the initial insult. These neurological complications include cerebral infarction, spinal cord ischemia, hemorrhagic stroke, seizures, and coma. Other features include an acute confusional state, autonomic dysfunction, and retinal ischemia. In this case series, we describe three patients with fat embolism syndrome who presented with atypical symptoms and signs and with unusual neuroimaging findings. Cerebral fat embolism may occur without any respiratory or dermatological signs. In these cases, diagnosis was established after excluding other differential diagnoses. Neuroimaging using brain magnetic resonance imaging is of paramount importance in establishing a diagnosis. Aggressive hemodynamic and respiratory support from the beginning and consideration of orthopedic surgical intervention within the first 24 hours after trauma are critical to decreased morbidity and mortality.

Total hip replacement is a crucial intervention for patients with fractured hips who face challenges in natural recovery. The design of durable prostheses requires a comprehensive understanding of the natural processes occurring in bone. This article focuses on static loading analysis, specifically during stumbling activity, aiming to enhance the longevity of prosthetic implants. Three distinct implants, Charnley, Osteal, and Thompson, were selected for a detailed study to determine the most appropriate model. The results revealed critical insights into the distribution of Von Mises stresses on the components of femoral arthroplasty, including the cement, implant, and cortical bone. Furthermore, the examination of shear stress within the cement emerged as a pivotal aspect for all three implants, playing a crucial role in evaluating the performance and durability of hip prostheses. The conclusions drawn from this study strongly suggest that the Thompson model stands out as the most suitable choice for hip joint implants.

Purpose: This study compared the effects of the elastic resistance and general training for college Taekwondo athletes, and investigated the biomechanical ability and lower extremity function according to the movement speed of the knee joint. Methods: Twenty university student Taekwondo athletes participated voluntarily in this study. The subjects performed general resistance training for four weeks, followed by elastic resistance training for another four weeks. The biomechanical parameters during the fast and slow isokinetic conditions, Y-balance ability, and vertical jump ability were measured three times: before training, after general resistance training, and after elastic resistance training. Statistical analysis was performed under isokinetic conditions and the intervention effect. Results: The biomechanical ability differed significantly between fast and slow isokinetic conditions (p<0.05). An analysis of the training method revealed a significant difference in the maximum knee extension speed and the posterior-lateral direction of the Y-balance test (p<0.05). Conclusion: Elastic resistance training had a more positive effect on the functional task performance than biomechanical factors related to muscular strength compared to general resistance training. In addition, speed-related knee biomechanical information of subjects with strong physical abilities could be utilized in sports physiotherapy.

Objective: This study aimed to explore the effects of a novel training program that integrates ultrasound technology to enhance the palpation skills of physical therapy students. The program was designed to support students in developing more precise palpation techniques by using ultrasound as a supplementary tool for anatomical identification. Design: A randomized controlled trial. Methods: A total of twenty students, all enrolled in the physical therapy department at S University, who met the specified selection criteria, were randomly assigned to one of two groups: the experimental group (EG, n=10) or the control group (CG, n=10). The experimental group participated in an ultrasound-assisted palpation training program, while the control group did not receive this intervention. Results:The experimental group demonstrated significant improvements in their ability to accurately palpate anatomical landmarks, specifically the long head of the biceps brachii (LHBT) and the lateral joint line of the knee (LJLK), as well as an increased level of confidence in their palpation skills (p<0.05). A comparative analysis of changes from pre- to post-training revealed statistically significant differences between the two groups (p<0.05). Conclusions: The findings of this study suggest that the ultrasound-assisted training program can provide valuable educational benefits, offering foundational data to enhance the development of palpation skills in physical therapy students and making a meaningful contribution to educational research within the field.

Stabilization splint therapy Precedes orthodontic intervention to enable the operator to find a 'true' centric(which is stable and comfortable), to test the patient's response to a change in the occlusion, prior to embarking upon a complex course of occlusal therapy : and finally, to see if the centric relation position can be stabilized. For this study, 47 malocclusion Patients enrolled for orthodontic treatment at the Department of Orthodontics, College of Dentistry, Chosun University comprised the malocclusion group, little variation of growth factor by the second molar eruption. They had Cr-Co discrepancy beyond normal range. For each patients the stabilization splint with mutually protected type of occlusal scheme was applied for 3 months. Condylar positions in CR and CO were measured using Penadent articulators, Panadent condylar position indicator(CPI), and transcranial projection before & after stabilization splint therapy. On the basis of this study, the results of this study were as follows 1. In all samples using CPI, there were statistical significances in CR-CO discrepancy(p<0.001) both before 8t after stabilization splint therapy. 2. In Rt and Lt+Rt/2 of superior joint space using transcranial projection, there were statistical significances in CR-CO discrepancy({<0.05) before & after stabilization splint therapy. 3. In supero-inferior components using CPI, there were statistical significances in CR-CO discrepancy(p<0.01) before & after stabilization splint therapy. 4. In all components except Rt using transcranial projection, there were no statistical significances in CR-CO discrepancy(p>0.05) before & after stabilization splint therapy. To sum up, CPI might be more effective than transcranial projection to reveal the changes between CR-CO discrepancies and stabilization splint might be more useful appliance for displaying the vertical changes, than the antero-posterior changes, of condylar position.

Background: Some 60 years after introduction of the Papanicolaou smear worldwide, cervical cancer remains a burden in developing countries where >85% of world new cases and deaths occur, suggesting a failure to establish comprehensive cervical-cancer control programs. Effective interventions are available to control cervical cancer but are not all affordable in low-income settings. Disease awareness saves lives by risk-reduction as witnessed in reducing mortality of HIV/AIDS and smoking-related cancers. Subjects and Methods: We initiated a community-based awareness program on cervical cancer in two low-income Muslim Uyghur townships in Kashi (Kashgar) Prefecture, Xinjiang, China in 2008. The education involved more than 5,000 women from two rural townships and awareness was then evaluated in 2010 and 2011, respectively, using a questionnaire with 10 basic knowledge questions on cervical cancer. Demographic information was also collected and included in an EpiData database. A 10-point scoring system was used to score the awareness. Results: The effectiveness and feasibility of the program were evaluated among 4,475 women aged 19-70 years, of whom >92% lived on/below US$1.00/day. Women without prior education showed a poor average awareness rate of 6.4% (164/2,559). A onetime education intervention, however, sharply raised the awareness rate by 4-fold to 25.5% (493/1,916). Importantly, low income and illiteracy were two reliable factors affecting awareness before or after education intervention. Conclusions: Education intervention can significantly raise the awareness of cervical cancer in low-income women. Economic development and compulsory education are two important solutions in raising general disease awareness. We propose that implementing community-based awareness programs against cervical cancer is realistic, locally affordable and sustainable in low-income countries, which may save many lives over time and, importantly, will facilitate the integration of comprehensive programs when feasible. In this context, adopting this strategy may provide one good example of how to achieve "good health at low cost".
