Purpose: The purpose of this study was to find out changes in muscle activity and body heat of tibialis anterior and gastrocnemius muscles according to the area touching the ground through the areas of different heel heights using electromyography and infrared thermography. Method: This study was carried out for 15 healthy women. After walking for 30 minutes, the body temperature was measured in a standing state in front of the measuring instrument, and the distance between the treadmill and the thermography was about 50M, which may cause an error in measurement. Result: The results of the comparison of changes in muscle activity and body heat showed significant differences all in tibialis anterior, medial gastrocnemius muscle an lateral gastrocnemius muscle. The changes in body heat of tibialis anterior and medial gastrocnemius muscles according to the shape of the heel were lower as the area of the heel touching the ground was wider. Conclusion: This study was conducted to find out changes in muscle activity and body heat of tibialis anterior and gastrocnemius muscle depending on the area touching the ground through different heel areas.

Background: Shoulder function is achieved by the coordinated movements of the scapula, humerus, and thoracic spine, and shoulder disorders can be associated with altered scapular kinematics. The trunk plays an important role as the kinematic chain during arm elevation. Objects: The purpose of this study was to determine the effects of thoracic hyperkyphosis on scapular orientation and trunk motion. Methods: Thirty-one subjects (15 in the ideal thorax group and 16 in the thoracic hyperkyphosis group) performed right-arm abduction and adduction movements in an unconstrained plane. The scapular orientation and trunk motion were recorded using a motion analysis system. Results: Those subjects with thoracic hyperkyphosis displayed greater scapular posterior tilting at a $120^{\circ}$ shoulder elevation, greater scapular internal rotation throughout the arm raising phase, and greater trunk axial rotation at the upper ranges of the shoulder elevation, compared to those subjects with an ideal thorax (p<.05). Conclusion: Thoracic hyperkyphosis can cause scapular instability, greater trunk rotation and greater scapular posterior tilting, and may contribute to preventing the achievement of a full range of humeral abductions in an unconstrained plane.

Posterior interosseus (PI) nerve compression is a rare form of compressive neuropathy. It can cause pain along the radial nerve course and weakness of radial nerve innervating muscles without sensory symptoms. A 65-year-old man visited our institution complaining weakness of finger extension and thumb abduction after 2 times of injections at the right elbow in local clinic. The patient's clinical history and physical examination implied an iatrogenic radial nerve injury caused by the injection. The electrophysiologic study revealed of posterior interosseus neuropathy (PIN) with incomplete conduction block. However, the ultrasound study showed that the PI nerve was compressed by an anechoic cyst. The magnetic resonance imaging also confirmed of a ganglion cyst, not a hematoma. After repeated aspirations and a steroid injection, the electrophysiologic study showed recovery of motor weakness. Despite of the clue which implying an iatrogenic injury, clinician should consider other possibilities such as ganglion cysts and ultrasound guided aspiration and steroid injection could be an effective option for conservative management.

Background: Backpacks are one of the most widely used accessories in modern society. However, previous studies have shown that carrying a backpack can cause various musculoskeletal problems. Objectives: To investigate the effects of a body-adhesive backpack on craniovertebral angle, sagittal shoulder angle and the muscle fatigue in the upper extremity. Design: Randomized cross-over design. Methods: For this study, 36 healthy university students participated in this study. The experiment was conducted three times using common backpack, and body-adhesive backpack condition. The angles of the cervical spine and shoulder joints of the subjects were calculated without the backpack. Electrodes were placed at upper trapezius, lower trapezius, rectus abdominis and erector spinae to check for muscle fatigue. Subjects carried a backpack and walked on a treadmill for 15 minutes at 4 km/h. The muscle fatigue signal was also measured while walking. After walking, the craniovertebral and sagittal shoulder angles were measured again while subjects carried backpack. Results: As a result of this study, body-adhesive backpack condition showed significant decrease and significant increase in craniovertebral angle and sagittal shoulder angle than common backpack (P<.05). Body-adhesive backpack condition showed significant decrease in upper trapezius, lower trapezius, erector spinae, and rectus abdominis when compared to a common backpack (P<.05). Conclusion: This study suggests that a body-adhesive backpack is more beneficial in correcting body posture than a common backpack.

Plantar heel pain is a common clinical problem in foot and ankle clinics. Typically, several conditions such as plantar fasciitis, fat pad atrophy, and calcaneal fracture may lead to plantar heel pain. However, subcalcaneal bursitis occurred between plantar fascia and plantar fat pad has rarely been described as a cause of plantar heel pain. To our knowledge, subcalcaneal bursitis has been reported only once, but there was no mention of preceding factors. We firstly present a case of subcalcaneal bursitis occurred after excessive walking exercise known as "Nordic walking" and successfully managed with conservative treatments that relieve impact on plantar heel.

Parkinson's disease(PD) is a progressive neurodegenerative disease that affects the functioning of the basal ganglia, a brain area that contributes to the control of movement. The disease is caused by the death of nerve cells in the brain that produce dopamine, a chemical messenger. The cells affected usually produce a neurotransmitter(a chemical that transmits nerver impulses) called dopamine, which acts with acetylcholine, another neurotransmitter, to fine-tune muscle control. In Parkinson's disease, the level of dopamine relative to acetylcholine is reduced, adversely affecting muscle control. When the supply of dopamine is depleted, the function of the basal ganglia is disrupted and its ability to control movement deteriorates. The result is that PD patients experience moderate rigidity, difficulty in initiating movements and slowness in executing them, and a rhythmical tremor at rest. Although the cause of Parkinson's disease is not known, genetic factors may be involved. About 3 in 10 people with the disorder have an affected family member. About 1 in 100 people over the age of 60 in the US have Parkinson's disease. And Parkinson's disease is slightly more common in men. The course of the disease is variable, but drugs may be the best effective in treating the symptoms and improving quality of life. But, The doctor may arrange physical therapy to help with physical mobility problems. It is important to continue to exercise and take care of your general health. Try to take a walk each day. Stretching exercises can help you maintain your strength and mobility. So, This papers will serve about the information of PD for clinical physical therapist. Finally, The aim of review is increasing approach method and technique for PD patients by the view of physical therapy.

Background: A typical plank exercise (PE) strengthens the core muscles, stabilizes the spinal column, and provides stability around the pelvis and trunk when the trunk is aligned. However, because PE require that the hip joint be kept straight, they can activate the hamstring (HAM). Excessive HAM activation can induce tightness, which may cause low back pain. Therefore, it is necessary to explore PE methods that can minimize HAM activity while maximizing core muscle activity. Design: Cross-sectional study. Methods: This study included 30 healthy adults as subjects. We measured the activity of the HAM and the erector spinae (ES), rectus abdominis (RA), and external oblique (EO) muscles using surface electromyography during three PEs (typical PE, PE with balance pad, and PE with sling). Results: The RA, EO, and ES showed the highest muscular activity during PE with balance pad and the lowest during PE with sling; however, the differences were not significant. The HAM showed lower activity during PE with sling than during the other two PEs; however, these differences were also not significant. Conclusion: Although HAM activation was not significantly difference among PE positions, we should recognize altering activation of core and hamstring muscle according to PE postures.

This paper studied the causes of job stress of driving crews working in Metropolitan Transit Authorities in Daejeon, Daegu, Seoul Metro Line 9, and Incheon, analyzing psychological, physical, and environmental factors, along withdriving crews' assignments. Regarding driving crews' assignments, it was found that driving crews had strong senses of obligation for their job, and hence their aptitude for their job was in accordance, and also it was found that most driving crews worked devotedly with a desirable occupational view and pride. However, psychological and physical factors that contributed to stress were identified: lack of sleep, high task burden, physical fatigue, and boring daily life. Furthermore, the driving crews' irregular working conditions and irregular meal time and burden related to on-time transit service with prolonged immobilization raised their stress levels. In terms of external environmental factors, it was found that driving crews' anxiety due to possible accidents caused a roughly four-fold increase in stress levels compared to other factors. Furthermore, personnel system and salary issue were also found to be closely related to the driving crews' job stress.

Recently, the damages by typhoons and heavy rains are increasing due to the climate change. However, we are still vulnerable to inundation disaster due to various causes such as poor physical flood control and lacks of disaster and safety management. Therefore, it is necessary to establish systems to ensure safety and prepare practical countermeasures that can minimize damage when an inundation occurs, thereby minimizing economic loss and casualty. In this study, hydrodynamic inundation modelings were implemented to analyze the "Noryangjin reservoir inundation accident" and "Choryang No. 1 underground road inundation accident." and spatial risk was assessed by a quantitative hazard index. In addition, cause and effect diagrams were provided to present the risk causes in terms of physical and managemental aspects.
