Almost of alternate computer access devices which assist people with disabilities to utilize the computer connected to computer by some cables or installed in as a S/W program. These devices have some spatial limitations to the people with disabilities, it can't guarantee the free and diverse access to the computer. For these reasons, in this paper, an Android-based mouse program for alternative computer access was developed. A people with physical disabilities who has some limitation of hand movements can use it in anywhere and anytime using only the fine motor skill of the upper limbs. The developed device recognizes the user's point touch and transforms it into the location of mouse cursor. The location information transferred to the computer via Bluetooth communication module equipped in smart devices. Also the group scanning method which can reduce the user's fatigue degree was employed and click, double click, drag & drop functions by hand's movements were equipped. The developed device will help the people with disabilities to use computer with brief touch and convenient operation without spatial limitation.

Background: Therapeutic climbing training, which originated in Germany, is a wall-hanging rock climbing-based therapy to increase the body's coordination through movement of the upper and lower limbs against gravity. However, there are no studies examining the effectiveness of therapeutic climbing training to treat balance and gait ability in patients with chronic stroke. Objectives: To investigate therapeutic climbing training program on balance and gait in patients with chronic stroke. Design: Pretest-posttest control group design. Methods: Fourteen patients with chronic hemiplegic stroke participated. Participants were randomized into the therapeutic climbing training group (TCTG, n=7) and the standard rehabilitation program group (SRPG, n=7) group. All subjects participated in the same standard rehabilitation program consisting of 60 minutes 5 times a week for 6 weeks. TCTG participated additionally in the therapeutic climbing program consisting of 30 minutes sessions 3 times a week for the same 6 weeks. Berg balance scale (BBS), Gaitview Measure, Timed up and go test (TUG) were measured. Results: In the TCTG, revealed a statistical difference in BBS between the groups; in the difference of plantar pressure ratio in the static standing position revealed a statistical difference between the groups after training; the balance ability in the one-leg standing tests increased significantly; the time in TUG decreased significantly after training in both groups; The changes in the difference of dynamic plantar pressure ratio were reduced significantly in the TCTG. Conclusion: Therapeutic climbing training contribute to improve balance and walking function in patients with chronic stroke.

Background: The most distal sensory fibers of the feet are often affected first in polyneuropathy. However, they are not evaluated in routine nerve conduction studies. Thus we evaluated the dorsal sural sensory nerve in patients with sensorimotor polyneuropathy with normal sural response, in order to assess the usefulness in electrodiagnostic practice. Methods: In this study, 53 healthy subjects and 27 patients with clinical evidence of sensorimotor polyneuropathy were included. In all subjects, peripheral motor and sensory nerve studies were performed on the upper and lower limbs including dorsal sural nerve conduction studies. On electrodiagnostic testing, all patients had normal sural responses. Results: The dorsal sural sensory nerve action potentials (SNAPs) mean amplitude was $13.12{\pm}5.68{\mu}V$, mean latency was $3.12{\pm}0.43msec$, and mean sensory conduction velocity (SCV) was $36.50{\pm}3.40m/s$ in healthy subjects. In 7 of 27 patients, the dorsal sural nerve SNAPs were absent bilaterally, and in 20 patients, the mean dorsal sural nerve distal latency was longer($3.40{\pm}0.48ms$, P=0.006), and mean SCV was slower than in healthy subjects($35.08{\pm}4.59$, P=0.043). However, dorsal sural nerve amplitude was not different between the groups (P=0.072). Conclusions: Our findings suggest that dorsal sural nerve conduction studies should be included in the routine electrodiagnostic evaluation of patients with suspected polyneuropathy and normal sural nerve responses.

Purpose: In this study, I am going to figure out Korean workers' actual exposure to risk factors and percentage of the workers who complain of health problems by performing a comparative analysis of the characteristics of the workers and working conditions in Korea and EU. Methods: The data used in this study includes the $1^{st}$ working conditions survey conducted in 2006 in Korea, the $2^{nd}$ working conditions survey in 2010, the $4^{th}$ EU working conditions survey, and the $5^{th}$ EU working conditions survey. I have compared the changes to Korean working conditions and those to EU working conditions in the categories of demographic characteristics, quality of labor, exposure to risk factors, and health problems included in the data. Results: The analysis of the characteristics of the demographic characters of Korean workers shows that aged and female workers register increased labor force participation. The analysis of labor quality shows that Korea has a long working time but with a lower work intensity compared to the countries included in EU working conditions survey. As for risk factors, Korea registers a low level of exposure as compared to countries included in EU working conditions survey and characteristically shows a decreasing exposure to tobacco smoke. The survey shows sharply increasing complaints of muscle pain in the upper and lower limbs. Conclusion: In this study, I have identified vulnerable social groups by using quantified values in a comparison of the working conditions of Korea and those of EU.

Background: Musculoskeletal pain is associated with obesity; however, information on factors associated with pain in adults with obesity and severe obesity is limited. The purpose of this study was to assess the prevalence of musculoskeletal pain by site and intensity of pain and associated factors in individuals with severe obesity (body mass index ≥ 35.0 kg/㎡). Methods: Baseline data from the DieTBra Trial study evaluating pain symptoms in nine body regions over the last seven days using the Nordic Questionnaire on Musculoskeletal Symptoms and Numerical Pain Scale. The variables analyzed using multiple Poisson regression with hierarchical analysis were: sociodemographic, lifestyle, food consumption, clinical, and anthropometric, and the outcome was moderate and intense pain. Results: In 150 participants, there was a high prevalence of ankle and foot pain (68.7%), lower back pain (62.7%), pain in the knees (53.3%) and upper back pain (52.0%), with a predominance of intense pain. Factors associated with pain according to specific sites were: type 2 diabetes with hand/wrist pain; sedentary time with hip pain; insomnia with pain in the hip and knee; edema in the lower limbs with pain in the lower back and ankles/feet; degree of obesity with ankle/foot pain; and percentage of total fat with ankle/foot pain. Conclusions: There was a high prevalence of pain and intense pain in individuals with severe obesity and an association with clinical variables, the degree of obesity, and sedentary lifestyle.

The purpose of this study was to verify the validation of effect on improvement of muscle strength unbalance according to exercise load deviation during rowing exercise. We performed evaluation of muscular activity and joint torque before the test. We recruited twenty subjects who one side's muscle strength is bigger in more 20% than other side. Subjects divided two groups. One is dominant left side and the other was dominant right side. Subjects performed rowing exercise in electric load deviation rowing equipment (Robo.gym, Humonic Co., Ltd., Daegu, Korea). Exercise performed four sets a day including 25 times a set, and three days a week. Measurements consist of evaluation of muscular activity and joint torque. Exercise load deviation adapted that different value of muscle strength in both arms multiplied 1RM% and added 1RM 50%. The results in adapted load deviation showed that the differences of maximal peak torque in 22.75% were getting increase significantly during exercise in 5.72%. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time for balance. Our study found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance.

Objectives: This study was to examine the features of work and posture analysis outputs in assessment of exposure to musculoskeletal disorder (MSD) risk factors in general hospital nurses. Methods: Work and posture analyses were carried out using observational approaches for nurses at general hospitals across Korea. With development of a taxonomy for assessing exposure to MSD risk factors, nursing tasks were documented in frequency (%time) for 8 hours a day in work analyses. Rapid Entire Body Assessment (REBA) scores were obtained for mode and maximum risk levels, respectively, during posture analyses. Results: A total of 27 nurses were observed while conducting 7 nursing tasks at 6 general hospitals. For both the work analyses and posture analyses, the taxonomy was developed and used. In the work analyses, 'Video display terminal task' and 'Nursing examination/ treatment' were the highest as 25%time for 8 hours a day, followed by 'Patient care' and 'Room rounding' as 13%time in order. In the posture analyses, the mode REBA scores were 2 or less for all nursing tasks while the maximum REBA scores were 7 for upper limbs at 'Room rounding' and 6 for trunk/neck/legs at 'Patient care'. Conclusions: The results showed the study nurses are occasionally at a risk for MSD, a medium level as designated in the REBA risk level, suggesting that it is important to control awkward posture at the nursing tasks such as 'Room rounding' and 'Patient care', in priority, for preventing MSD in the hospital sector including the study general hospitals.

Objective: Cerebral palsy (CP) is a neurodevelopment disorder attributed to an insult or injury to the developing brain with abnormalities in muscular tone, movement and motor skill. Improvement in quality of life and ameliorating symptoms can be achieved. Therefore, this case report details a distinctive approach to treating a 5-year-old male child with quadriplegic spastic cerebral palsy utilizing Unani treatment modalities. Methods: The treatment regimen commenced with 'Habb Ayarij for constipation followed by Sharbat Ustukhuddus administered orally. Notably, Sharbat Ustukhuddus was combined with Melia Azedarach L. leaves vapour bath. Subsequently, Roghan Babunna douche was performed followed by Dalk Layyin andcontinued until symptomatic improvement was observed. Majun Falasfa, Khamira Marwareed and Khameera Gauzaban were administered for 30 days. The therapeutic outcome included anthropometrical measurements, developmental milestones, spasm/reflex scale, and muscle power grading. Results and conclusion: Over the course of a 2-year follow-up, several clinical findings emerged. These included notable improvements in anthropometric measurements, developmental milestones such as improved head control and sitting ability, and a reduction in spasticity of the upper limbs, along with decreased muscle spasms. The therapeutic outcome of this individualized and holistic approach is potentially due to the multifaceted properties of medicinal plants (Musakkin wa Muharrik wa Muqawwi-i- A'sab wa Dimāgh, Munawwim, Dafi-i-Tashannuj, Muqawwi-i-Qalb-i-Ruh). Furthermore, the use of Dalk and Naṭūl was instrumental in providing nourishment to musculoskeletal cells and initiating intracellular signaling cascades. While these findings are encouraging, further research in the form of case series andrandomized controlled trials is warranted to validate the efficacy of this unique holistic approach.
