The purpose of this study was to identify the effects of continuous muscle strengthening applied to the antagonist of the sternocleidomatoid, upper trapezius, and pectoralis major, which are the shortened muscles of forward head posture(FHP) subjects, and Evjenth-Hamberg stretching(EHS) applied to the shortened muscles on changes in pressure pain threshold(PPT). Twenty subjects were divided into the continuous antagonist strengthening(CAS) group(n=10) and the EHS group(n=10), and each group performed its respective exercise three times a week for a six week period. The results were as follows: The comparison of changes in PPT within each group before and after the treatment showed a statistically significant difference(p<.05) according to the treatment period and a statistically significant difference according to the treatment period and method(p<.05). While the comparison of the tests of between subjects effects between the groups did not show a statistically significant difference, the CAS group exhibited better effects. The above results suggest that the combined application of CAS and EHS generates better effects on changes in PPT than the single application of EHS. Given that stretching and muscle strengthening exercises even for the short research period of six weeks could change the PPT, continuous exercises and a correct postural habit for a longer period of time are likely to help prevent chronic pain and correct FHP.

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 aimed to adjust the craniovertebral angle and shoulder alignment through shoulder and abdominal stabilization exercises in adults with a forward head posture. Methods: The study participants were 29 adults with a forward head posture, and they were randomly divided into the following groups: 14 participants in a combined exercise group that used shoulder and abdominal stabilization exercises and 15 participants in a shoulder exercise group that used just shoulder stabilization exercises. The participants performed the stabilization exercises for 30 minutes per day, three times a week for five weeks. Results: There were significant differences in the craniovertebral angle after intervention in the shoulder stabilization exercise group (p < 0.05). There were significant differences in the craniovertebral angle and location of the right root of the spine and both inferior angles before and after intervention in the shoulder and abdominal stabilization exercise group (p < 0.05). There was a significant difference in the location of the right root of the spine and the left inferior angle between the groups at the post-test (p < 0.05), and there was a larger change in the shoulder and abdominal stabilization exercise group. Conclusion: There was a significant difference in the craniovertebral angle and a partially significant difference in shoulder alignment before and after intervention in both groups.

본 논문에서는 환자의 자세를 기반으로 행동을 예측하여, 의료진에 의해 입력된 개인의 병력 중심의 프로파일과 신체정보, 침상의 기본 정보를 모두 조합하여 침대에서의 낙상 위험을 예측하는 모델을 설계하고, 위험의 수준을 판단할 수 있는 알고리즘을 제시한다. 낙상 위험 예측은 크게 환자의 프로파일을 활용한 정성적 낙상 위험 노출도 평가와 실시간 낙상 위험 측정 단계로 구분된다. 정성적 낙상 위험 노출도는 의료진이 낙상 위험과 관련된 환자의 건강 상태를 점검하여 위험 노출도를 평가함으로써 위험 등급이 결정된다. 실시간 낙상 위험 측정 단계에서는 환자의 침대에서의 자세를 인식하고 환자의 정성적 위험등급 정보가 고려된 낙상 위험 측정을 위한 규칙 기반 정보를 추출한다. 인식된 환자 자세 정보와 정성적 위험평가 정보를 모두 조합하여 시그모이드 함수를 활용하여 최종 낙상 위험 수준을 예측한다. 본 연구에서 제시된 절차와 예측 모델은 입원 환자를 위한 낙상 사고 예방과 환자 안전을 위한 개인화 서비스에 크게 기여할 것으로 기대된다.

Gait is defined as "a manor of walking". It can used as a biometric measure to recognize known persons. Gait is an idiosyncratic feature determined by an individual's weight, stride length, and posture combined with characteristic motion. but its feature extracted from images varies with the viewpoint. In this paper, we propose a gait recognition method using a planer homography, which is robust for viewpoint variation. We represent an individual as key-silhouettes. And we endow key-silhouettes with weight calculated using the characteristic of PCA. Experimental result shows that proposed method is robust for viewpoint variation as images synthesised same viewpoint.

Background: Although many of those who drive for a living are exposed to repetitive and awkward posture and whole body vibration which cause them cumulative trauma disorder, therapeutic studies related to the problems from the transport unit are still somewhat inadequate. The purpose of this case report is to identify the effect of combined exercise program on patients suffering chronic neck pain caused by long hour of intra-city bus driving. Method: A total of 4 subjects are selected as patients, all of whom have more than 10 years of experience in intra-city bus transportation services. These people have suffered from neck pain for years. We ran the combined exercise program 3 times a week for 4 weeks and respectively evaluated the results after the 2nd and 4th week. We implemented conventional physiotherapy for 40 minutes, another 40 minutes of combined exercise program, and then educated the patients to enable themselves to do active stretching program as a home program. The combined exercise program contained 3 different stages. 1st stage: active stretching program, 2nd stage combined stabilization exercise and strengthening exercise, 3rd stage: proprioceptive exercise Result: After 4 weeks of intervention, there was enhance in the range of motion. $12^{\circ}$ increase in flexion, $10^{\circ}$ in extension, $6^{\circ}$ in lateral flexion respectively, and $10^{\circ}$ in rotation on average. VAS(visual analgue scale) decreased by 33% on average, NDI(neck diability index) by 28% and fatigability by 23%. Conclusion: There were improved results in the range of motion, NDI, VAS, and in fatigability after applying combined exercise program to intra-city bus drivers exposed to whole body vibration and cumulative trauma disorder.
