This study was designed to assess the effects of a rehabilitation program on clinical symptoms, subacromial space parameters and the supraspinatus vascularity in individuals with subacromial impingement syndrome (SIS). Methods: Thirty-five participants (exercise group with SIS [EG]=11, non-exercise group with SIS [NEG]=10, control group [CG]=14) took part in this study. Only EG participated in 6-week rehabilitation program. Outcomes were evaluated at baseline, 6 weeks, and 10 weeks. Changes in symptoms and functional limitations were assessed using Shoulder Pain and Disability Index (SPADI) questionnaire. Changes in acromiohumeral distance (AHD) and supraspinatus tendon thickness (STT)/AHD were assessed using ultrasonographic measures. Quantitative analysis of tendon blood flow was performed by determining four regions of interest with power Doppler quantification and analysis software to normalize data for interpretation of the mean ratio of colored pixel to the region of interest (vascularization index [VI]) and the intensity per pixel (flow index [FI]). Results: Following the rehabilitation program, the scores on SPADI were significantly improved (p＜0.05). However, AHD, STT/AHD, VI, and FI indicated no significant difference within groups or interactions of time and group in between groups. Conclusion: The rehabilitation program yielded improvements in symptoms, but not in subacromial parameters and the vascularity of supraspinatus in participants with SIS.
Clinical Practice Guideline on Acupuncture for Post-stroke Spasticity
Journal of Korean Medicine, 2015
This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the patients with post-stroke spasticity. Methods: Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on post-stroke spasticity, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions: One systematic review and 7 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of electroacupuncture treatment for post-stroke spasticity. However, it did not show any sufficient evidence to treat the patients with post-stroke spasticity with the sole acupuncture. The moderate evidence was presented that over 3 times of the electroacupuncture treatments with 1-100 Hz frequency should be performed every week on the acupoints, such as LI11, LI10, TE5, LI4, ST36, GB34, ST40, or LR3, for 20-30 minutes. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. Finally, there was a moderate evidence to support safety of acupuncture treatment for post-stroke spasticity.

This study examined the effects of a physical therapy program on quality of life (QOL), and neck and shoulder disability in head and neck cancer patients. The program included neck and shoulder range of motion (ROM) exercises, massage, progressive strengthening exercises, and stretching exercises. Sixteen patients who were assigned to an experimental group performed physical therapy for 40 minutes three times a week for eight weeks. Fifteen other patients were assigned to a control group who did not performed the physical therapy program. The European organization for research and treatment of cancer (EORTC QLQ-C30) and head and neck (EORTC QLQ-H&N) instruments, and the Neck Disability Index (NDI) were assessed before and after the rehabilitation program. The 40-minute program consisted of a 10-minute ROM exercise for the neck and shoulder, a 10-minute massage and 15-minute of progressive resistance exercises, followed by a five-minute stretching exercises. Statistically significant differences were noted for changes in global health, physical function in the EORTC QLQ-C30 and cancer related symptoms in the EORTC QLQ-H&N35 (p<.05). The NDI also showed significant differences (p<.05). Physical therapy may therefore benefit the physical aspects and QOL and improve neck and shoulder disability in patients with head and neck cancer.

Musculoskeletal disorders of the elderly and women in agricultural environment often come from the uncomfortable positions to heavy work for a long time or carrying more exposed the situation which includes repetitive tasks, uncomfortable working postures, heavy material handling and transportation. In order to prevent MSDs and improve work environment in agricultural work, this paper introduces some human factor engineering efforts which has been made in term of farmer-centered design and evaluation of tools and equipment. And it also has conducted a survey on the improvement satisfaction.
Virtual reality based stroke rehabilitation
Journal of the Korean Medical Association, 2013
V irtual reality (VR) is defined as an approach to user-computer interface that involves real-time simulation of an environment, scenario, or activity that allows for user interaction via multiple sensory channels. In recent years, virtual reality has grown immensely with rapid advancement of VR technologies in the field of stroke rehabilitation. In this paper, current VR applications to the field of rehabilitation are reviewed. In the field of stroke rehabilitation, many clinical trials related to VR-based assessment and treatment have been performed to assess and treat arm dysfunction, walking ability, visuospatial problems, cognitive dysfunction, etc. Among them, VR is beneficial in improving arm function when compared with conventional therapy with limited evidence. Whether VR improves walking, visuospatial problems, or cognitive function has not been well established yet. However, VR can simulate the real environment without the risks arising from errors, and can also give a sense of immersion in the simulated environment and a concomitant feeling of 'presence'. Moreover, VR provides the motivation of gaming factors. With these advantages, VR will be one of the major advanced technologies for assessment and managing post-stroke dysfunction in the future.
Shake Table Testing of Steel Braced Frame Considering Member Fracture
Key Engineering Materials, 2018
The authors have proposed a method to assess local fracture of concentric braced frames under cyclic loading from global member results termed the Direct Local Strain Evaluation Method. In this method there is no need to use detailed member shell models to estimate the strain at the fracture point in the braces. This enables accurate time history response analysis using less computationally intensive stick models, while including the effect of local member fracture. However, up to now, the accuracy of the proposed method has only been validated under static loading. This research validates the proposed method with dynamic numeric and shake table testing. The proposed method is effective in simulating the braced frame response including the brace fracture under dynamic loading.
