PURPOSE: This study aimed to provide basic clinical data by analyzing the impact of motion observation training and stretching exercises for improving postures on the neck alignment and balance of stroke patients to enable them to accurately recognize the correct exercise method. METHODS: After sampling 20 stroke patients who met the selection criteria, this study randomly assigned 10 people who were administered the stretching exercise with observation training to the experimental group and 10 who received only the stretching exercise intervention to the control group by drawing lots. Next, neck alignment and balance were pre-tested. All interventions were conducted for 30 minutes, 3 times a week for 4 weeks, and when all the interventions were completed after 4 weeks, neck alignment and balance were re-measured in the same way as the pre-test. RESULTS: The comparison of changes in neck alignment and balance within the experimental and control groups showed statistically significant differences in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). Between the groups, statistically significant differences were found in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). CONCLUSION: A statistically significant difference in neck alignment and balance was observed in the group that underwent stretching exercises combined with observational training and a statistically significant difference was found between the groups. Therefore, it is believed that observation training should be used in clinical practice to improve forward head posture and restore balance in stroke patients.

Purpose : This study examined the effects of pain, neck dysfunction, psychosocial level, headache impact test (HIT), postural alignment, and trapezius muscle tone of the complex exercise program using dynamic taping in patients with tension headache and chronic neck pain with forward head posture. Methods : The design of this is a randomized controlled trial (RCT). Thirty-four patients with chronic neck pain were screened using a randomized assignment program and assigned to experimental group (n=17) and control group (n=17). Both groups underwent a complex exercise program. In addition, the experimental group dynamic taping was applied to the upper trapezius muscle. All interventions were applied three times per week for four weeks. The visual analogue scale (VAS), the neck disability index (NDI), short form-12 health survey questionnaire (SF-12), Headache impact test-6 (HIT-6), Craniovertebral angle (CVA), Cranial rotation angle (CRA), upper trapezius muscle tone were compared to evaluate the effect on intervention. Results : Both groups showed significant differences before and after the intervention in VAS, NDI, SF-12, HIT-6, and CVA, CRA (p<.05). In addition, significant differences in NDI and upper trapezius muscle tone were observed between the experimental group and control group (p<.05). Conclusion : A complex exercise program using dynamic taping for patients with tension headache and chronic neck pain with forward head posture are effective method with clinical significance in improving the function and reducing upper trapezius muscle tone.

Background and Objectives We evaluated the clinical characteristics and vestibular function of patients with direction changing vibration induced nystagmus (DC VIN) and unilateral vestibular hypofunction and suggest clinical implication and a proposed mechanism of DC VIN. Subjects and Method The records of 315 patients who underwent the VIN test were reviewed retrospectively. Among these, 18 patients (5.7%) showed DC VIN, and out of whom, 15 patients (4.8%) were diagnosed as unilateral vestibular hypofunction by caloric, rotation chair (RCT), and video head impulse test (vHIT). We analyzed the relationship between DC VIN and the dizziness characteristics, duration of disease, and the outcome of the vestibular function test. Results The mean age of 15 patients was $67.4{\pm}10.7years$ and the mean duration of dizziness was $13.6{\pm}29.7months$. The caloric test revealed 25% of the patients to have significant canal paresis [Caloric vestibular neuritis (VN)], while 75% showed normal caloric response. However, unilateral vestibular hypofunction was observed by abnormal results in RCT or vHIT (Non-caloric VN). Seven patients showed ipsilateral DC VIN (nystagmus to vibrated side) and eight patients contralateral DC VIN (nystagmus to opposite side of vibration). Patients with ipsilateral DC VIN were shown to have a significant longer duration of dizziness than those with contralateral DC VIN. Conclusion Although rare, DC VIN can also be found in patients with unilateral vestibular hypofunction. Patients with DC VIN had a mild vestibular asymmetry with Non-caloric VN or Caloric VN in the process of compensation. The mechanism of ipsilateral DC VIN seems to be due to the small amount of vestibular asymmetry, which is smaller than the interaural attenuation of vibration.

목 적: 최근 Radixact^® X9에서는 치료테이블의 처짐을 방지하는 Catcher^TM가 추가되었다. 본 연구에서는 정확한 선량전달을 위한 토모테라피의 메가볼트 전산화단층촬영(MVCT) 영상유도방사선치료 시 Tomo-HDA^®의 General Couch와 Radixact^® X9의 Catcer^TM Couch의 치료테이블 처짐 정도를 팬텀을 이용하여 정량적으로 비교하고 그 유용성을 평가하고자 한다. 대상 및 방법: 팬텀연구를 위해 란도팬텀을 이용하였으며, 치료부위에 따른 변화를 위해 두경부와 골반부에 중심점을 설정하였다. 또한, 무게에 따른 변화를 위해 자체 제작한 저용융점납합금을 이용하였다. 납합금의 무게를 점차 증가시켜(A: 15kg, A+B: 30kg, A+B+C: 45kg) MVCT 영상을 획득하였으며, 수직오차 및 회전(Pitch)오차를 측정하였다. 환자연구를 위해 본원에서 토모테라피를 이용하여 방사선치료를 받은 120명의 환자를 선정하였다. Tomo-HDA^®과 Radixact^® X9에서 각각 60명씩 치료를 받았으며, 치료부위는 두경부와 골반부로 30명씩 분류하여 선정하였다. 환자연구 방법으로는 치료 첫 날 획득한 MVCT 영상의 척추를 기준으로 수직오차 및 회전(Pitch) 오차를 측정하여 평균값을 산출하였다. 결 과: 팬텀연구 결과 Tomo-HDA^®의 General Couch에서는 무게가 증가함에 따라 두경부와 골반부 모두 수직 및 회전(Pitch)오차가 비례하여 증가하였고, 두경부에서 최대 7.52mm, 0.38°, 골반부에서 최대 11.94mm, 0.92° 발생하였다. Radixact^® X9의 Catcher^TM Couch에서는 0.02~0.1mm, 0~0.04°의 오차범위가 발생하는 것을 확인할 수 있었다. 환자연구 결과 Radixact^® X9의 Catcher^TM Couch에서 두경부 4.79mm, 0.33°, 골반부 7.66mm, 0.22° 더 낮게 측정되었다. 결 론: 팬텀연구 결과 Tomo-HDA^®의 General Couch에서는 무게가 증가함에 따라 수직오차 및 회전(Pitch) 오차가 비례하여 증가하였으며, 특히 두경부보다는 골반부에서 더 많이 증가하였다. 하지만, 본 연구의 목적인 Radixact^® X9의 Catcher^TM Couch에서는 무게와 부위라는 변수상관 없이 일정한 오차가 발생하였다. 결론적으로 Catcher^TM Couch는 Couch 처짐이라는 Mechanical error를 최소화 할 수 있으며, 두경부보다는 골반부에서 더 유용하게 작용한다는 사실을 알 수 있었다. 토모테라피를 이용한 방사선치료 시 Radixact^® X9의 Catcher^TM Couch를 사용한다면 토모테라피의 특성상 보정할 수 없는 회전(Pitch)오차를 최소화하는데 기여할 수 있을 것이라고 사료된다.

두경부 종양에서 표적용적(target volume)을 하나의 조사야로 포함하지 못하는 경우는 조사야를 둘, 또는 그 이상으로 접합시켜 방사선치료를 시행한다. 방사선치료 시 두 조사야 경계면에서 균등한 선량을 부여하는 것이 매우 중요하다. 하지만 환자의 외형적인 인자나 전신 상태에 따라 피부 접합면( skin Junction area)의 불일치가 발생할 수 있으며 이로 인한 접합면에서의 과선량 또는 저선량 영역이 존재할 수 있다. 본 연구는 두경부 종양의 측면 조사면 끝단 차폐물(edge block)을 회전 가변형으로 제작하여 피부 접합면에 균등한 선량을 부여할 수 있는 치료 기술에 대하여 연구하였다. 모의치료에서 전방 상쇄골 하림프절(supraclavicle lymph node)의 중심선을 우측방 조사야 하단과 접합면으로 하여 회전 가변형 차 폐물을 이용하여 변형되는 거리와 회전각을 측정하였다. 연구 결과에서 원발병소와 상부 경부 림프절 우측방 조사야의 하단에서 회전 가변형 차폐물의 변형 거리는 Y축 중심선에 수직인 ${\pm}$10cm 거리에서 2mm 이내 였으며, 회전각은 평균적으로 약 1.28도의 회전 변형이 발생하였다. 하지만 조사면 끝단 차폐물을 회전 가변형으로 제작함으로서 기존에 발생하던 피부 접합면에서의 불일치를 최소화 할 수 있었다. 두경부 종양의 경우는 원발병소와 상, 하부 경부 임파절에 적절한 선량을 부여하기 위한 조사면 끝단 차폐물을 이용한 방법이 임상에서 적용할 수 있는 효율적인 방안이라 사료된다.

This study were to review of muscle imbalance of head, cervical and shoulder region. Head, cervical and shoulder region is a complicated mechanical unit. interconnected by numerous soft tissue links. These links, or articulation are functionaly and reflexly interdependent on one another. The line of gravity falls anterior to the transverse axis of rotation for flexion and extension of the head and creates a flexion moment. which tends to tut the head forward, is counteracted by tension in the tectorial membrane, and ligamentum nuchae, and by activity of the neck extensors. Therefore, the flexion moment equilibrate with the extension moment. Changing of the equilibrium will make mid cervical straight. It will make forward head posture(FHP) also. FHP makes imbalance of suboccipital muscles, suprahyoid muscles and infrahyoid muscles. It has some relationship with temporomandibular joint, spine and equilibrium of pelvis.

Purpose: The purpose of this study was to investigate the effects of neck patterns in proprioceptive neuromuscular facilitation (PNF) for neck movement and the neck disability index (NDI) among adults with forward head posture. Methods: Thirty-nine subjects were randomly assigned into two groups. Subjects in the proprioceptive neuromuscular facilitation exercise group (PNFG, n = 20) received 20 minutes of PNF neck pattern (flexion-Rt. lateral flexion-Rt. rotation followed by extension-Lt. lateral flexion-Lt. rotation) 3 times weekly for 4 weeks. Outcomes were measured using absolute rotation angle (ARA), anterior weight bearing (AWB), range of flexion and extension motions (RFEM), and neck disability index (NDI) methods before and after the 4-week intervention period. Results: There were significant effects for the PNFG, pre- and post-intervention, in ARA, AWB, RFEM, and NDI. There were significant differences in ARA, AWB, RFEM, and NDI compared with CG. Conclusion: The results of this study suggest the PNF neck pattern could be beneficial for adults with forward head posture.Purpose: This study investigates how abdominal muscular exercise based on proprioceptive neuromuscular facilitation (PNF) can affect chronic low back pain patients in terms of their pulmonary function, pain, and functional disability indexes. Methods: Fourteen target subjects with chronic low back were randomly assigned to the control group (n = 7) that performed abdominal muscle exercises and the experimental group (n = 7) that performed PNF abdominal muscular exercises. The exercises were performed five times a week for six weeks. To check the change in pulmonary function, the forced expiratory volume at one second (FEV1) and visible analogue scale (VAS) were measured to check the pain level. The disability level caused by back pain was measured by the Oswestry Disability Index (ODI). A paired t-test was applied to compare the differences between the groups before and after the intervention, and an independent t-test was used to compare the differences between the groups. The level of statistical significance was set as ${\alpha}=0.05$. Results: Before and after the intervention, the experimental group showed a significant change in FEV1 (p < 0.01), and both the experimental and the control groups showed significant changes in VAS and ODI (p < 0.01). A comparison of the differences between the groups indicated that the experimental group showed more significant changes in FEV1 (p < 0.05). Conclusion: According to the study results, PNF abdominal muscular exercise effectively improved pulmonary function, pain, and functional disability indexes in subjects with chronic back pain. The proposed program can be applied to chronic back pain patients as a useful therapy.

Purpose: The aim of this study was to investigate the effect of mandible position on proprioception and range of motion (ROM) during neck stabilization exercise using a sling in healthy adults. Methods: The subjects were randomly assigned to either a sling exercise and mandible open group (n=10) or a sling exercise and mandible closed group (n=12). The sling exercise-mandible open group and sling exercise-mandible closed group took part in an exercise program for 30min, three times per week for 4 weeks. After each training session, head repositioning accuracy (HRA) and the ROM of the cervical spine were measured. Wilcoxon's test was conducted to verify changes within each group, and the Mann-Whitney U test was performed to examine between-group differences. Results: The HRA of the cervical spine was significantly increased during left rotation and extension in the sling exercise-mandible open group. In addition, there were significant differences in both rotations and extension in the two groups. The ROM of the cervical spine increased significantly during both rotations in the sling exercise-mandible closed group. In addition, there was a significant difference in right rotation and extension in both groups. Conclusion: Cervical stabilization exercise using a sling, with the mandible closed increased proprioception and the ROM of the cervical spine.

Objective: Congenital muscular torticollis (CMT) is a disease with abnormal head and neck posture in infants. It affects the child's movement and development and can lead to complications. Therefore, this study aims to find out what factors influence the rehabilitation treatment duration of infants with CMT. Design: Cross-sectional study. Methods: The subjects were 63 infants under 90 days of age who were diagnosed with CMT. Age, thickness of the sternocleidomastoid muscle (SCM) on the affected and non-affected side, head tilt angle, and head rotation angle of the affected head in infants were collected. The ratio of muscle thickness was calculated from the thickness of the affected SCM and the thickness of the non-affected SCM (A/N ratio). All subjects underwent conservative physical therapy twice a week for 30 minutes, and the end of the treatment was when the angle of head tilt was normal or less than 5 degrees, and the treatment duration was calculated. Results: Age, thickness of affected SCM, and head tilt were significantly correlated with treatment duration (p<0.05). The thickness of the non-affected SCM, A/N ratio, and head rotation angle did not show any correlation with treatment duration. The factors affecting the treatment duration were head tilt and age, showing 21% explanatory power of adjusted R². Conclusions: The main factors affecting the treatment duration of infants with CMT are head tilt and age. Therefore, more attention should be directed to the infant's head tilt and age for effective physical therapy of infants with CMT.
