인간 정신은 외상 자극에 역동적으로 반응하여 다차원적 위계를 따라 진화적으로 발전하는 시스템이다. 평형상태에서 일원화되어 있는 정신 내에 외상 자극이 유입되면 그에 반대 쌍이 되는 반응 극성이 형성되어 이원화된다. 그 반대 쌍 사이에 초월적 상호작용이 일어나면 상위 차원에 제3의 극성이 출현하게 되어 정신은 삼위구조로 변형된다. 삼위 구조화된 정신에서는 비평형 상태가 극대화되어 가소성이 최대화됨에 따라 삼위 요인이 같은 기능을 하게 되는 동기화가 가능해지며 이로 인해 정신은 상위차원에서 다시 일원화된다. 만약 정신이 또 다시 새로운 자극을 받아들이게 되면 정신은 위의 위계적 변형과정을 따라 성장하게 된다. 이를 정신의 기본삼위체계의 동기화를 통한 순환적 성장과정이라 한다. 이번 이론 연구에서는 이 개념을 외상 후 성장 과정에 적용하여 외상 후 성장 시계를 제안하였다. 외상 후 성장 시계는 7개의 위계적 단계로 구성되어있으며 처음 6개의 단계들은 충격 대 마비, 공포 대 침습, 편집 대 회피, 강박 대 폭발, 불안 대 우울, 허무 대 의미추구 단계 등의 12분기로 구성되어 있고 마지막 7번째 단계에서는 이들 모든 단계들의 기능들이 동기화되는 거대 동기화 단계가 나타나게 된다. 거대 동기화 단계에서는 이전의 6 단계들로 구성된 개인 내의 생리-사회-실존 차원들 뿐 아니라 자아와 타아도 동기화를 통해 일원화됨으로써 자신의 외상경험 뿐 아니라 타인의 고통도 자신의 실제적 외상경험으로 작용하게 되어 정신은 상위 차원에서 또 다른 성장과정을 반복한다. 이 논문에서 제안된 외상 후 성장 시계의 변형과정에 대한 타당성을 Horowitz의 외상반응과정과 비교하여 논의하였다.

Background: The presence of visuospatial impairment can make patients slow functional recovery and impede the rehabilitation process in TBI patients. Objective: The aim of this study is to investigate effects of prism adaptation treatment for functional outcomes in patients following traumatic brain injury. Methods: The subject received prism adaptation treatment for 2 weeks additionally during traditional rehabilitation for 4 weeks. The Patient has prism adaptation treatment while wearing wedge prisms that shift the external environment about $12^{\circ}$ leftward. The patient received 10 sessions, 15-20min each session. Outcome measures were visuospatial deficit(line bisection, latter cancellation), Visual and spatial perception(LOTCA-visual perception and spatial perception), motor function of upper extremity(FMA U/E; Fugl-Meyer motor assessment upper extremity, ARAT; Action research arm test), balance(BBS; Berg Balance Scale), mobility(FAC; Functional ambulation classification) and functional level(FIM; Functional independent measure). All Assessments took place on study entry and post-treatment assessments were performed at discharge from the hospital. Results: After prism adaptation, the visuospatial impairment scores improved as indicated in the line bisection(-15.2 to -6.02), latter cancellation(2 to 0) and LOTCA- spatial perception scores(7 to 9). The upper motor function improved as indicated in the scores of affected FMA U/E(21 to 40) and ARAT(4 to 22). Ambulation and balance improved as indicated in the BBS scores(25 to 38) and FAC scores(0 to 4). ADL function improved as indicated in the FIM total scores 54 to 70(motor 34 to 61, cognition 20 to 29). Conclusion: Prism adaptation did improve functional level such as motor functions and ADL abilities in TBI patient. Further research is recommended.

Objective : We studied whether frontal skull base fracture has an impact on the occurrence and recovery of anosmia and/or ageusia following frontal traumatic brain injury (TBI). Methods : Between May 2003 and April 2005, 102 consecutive patients who had hemorrhage or contusion on the frontal lobe base were conservatively treated. Relevant clinical and radiographic data were collected, and assessment of impaired smell and taste sensation were also surveyed up to at least 12 months post-injury. Results : Among 102 patients, anosmia was noted in 22 (21.6%), of whom 10 had ageusia at a mean 4.4 days after trauma. Bilateral frontal lobe injuries were noted in 20 of 22 patients with anosmia and in all 10 patients with ageusia. Frontal skull base fracture was noted in 41 patients, of whom 9 (21.4%) had anosmia and 4 (9.5%) had ageusia. There was no statistical difference in the occurrence of anosmia and ageusia between patients with or without fracture. Of the 22 patients with anosmia, recovery from anosmia occurred in nine (40.9%) at the interval of 6 to 24 months after trauma, of whom six had frontal skull base fracture and three were not associated with fracture. Recovery of anosmia was significantly higher in patients without fracture than those with fracture (p<0.05). Recovery from ageusia occurred in only two of 10 patients at the interval of 18 to 20 months after trauma and was not eminent in patients without fracture. Conclusion : One should be alert and seek possibile occurrence of the anosmia and/or ageusia following frontal TBI. It is suggested that recovery is quite less likely if such patients have fractures on the frontal base, and these patients should wait for at least 6 to 18 months to anticipate such recovery if there is no injury to the central olfactory structures.

Benign peripheral nerve tumors, although infrequent, must be considered as a possible cause of pain and disability in the extremities. There are three varieties of these tumors that are of clinical importance: neurilemmomas, neurofibromas, and post-traumatic neuroma. Neurilemmomas are the most common primary solitary tumor of the peripheral nerve trunks, and are almost always benign, Neurofibromas may occur as a solitary nerve tumor, but can present as multiple lesions as in von Recklinghausen's disease. Clinically, this tumor may presents as a solitary mass in the subcutaneous tissue which is centrally located with the nerve fibers travelling through the tumor mass. Traumatic neuroma is the proliferation of nerve elements with connective tissue during the process of regeneration from severed nerves undergoing Wallerian degeration, and is therefore not a true neoplasm. A neuroma-in-countinuity is the result of partial severance of a nerve, or of a crushing or traction injury in which all or part of the epineurium and perineurium is intact. We experienced each of the three varieties. With magnification, the neurilemmoma was removed by meticulous dissection from the parent nerve preserving the normal fascicles to which it was attached. The neurofibroma was excised and the nerve was reconstructed with interposed vein graft and the neuroma-in-continuity was excised and reconstructed with sural nerve graft. We report histologic characteristics of each tumors and the methods to repair the nerve defects after tumor excision with brief discussion.

Objective : This study aimed to compare the clinical and radiologic outcomes of patients with subaxial cervical injury who underwent anterior cervical discectomy and fusion (ACDF) with autologous iliac bone graft or polyetheretherketone (PEEK) cages using demineralized bone matrix (DBM). Methods : From January 2005 to December 2010, 70 patients who underwent one-level ACDF with plate fixation for post-traumatic subaxial cervical spinal injury in a single institution were retrospectively investigated. Autologous iliac crest grafts were used in 33 patients (Group I), whereas 37 patients underwent ACDF using a PEEK cage filled with DBM (Group II). Plain radiographs were used to assess bone fusion, interbody height (IBH), segmental angle (SA), overall cervical sagittal alignment (CSA, C2-7 angle), and development of adjacent segmental degeneration (ASD). Clinical outcome was assessed using a visual analog scale (VAS) for pain and Frankel grade. Results : The mean follow-up duration for patients in Group I and Group II was 28.9 and 25.4 months, respectively. All patients from both groups achieved solid fusion during the follow-up period. The IBH and SA of the fused segment and CSA in Group II were better maintained during the follow-up period. Nine patients in Group I and two patients in Group II developed radiologic ASD. There were no statistically significant differences in the VAS score and Frankel grade between the groups. Conclusion : This study showed that PEEK cage filled with DBM, and plate fixation is at least as safe and effective as ACDF using autograft, with good maintenance of cervical alignment. With advantages such as no donor site morbidity and no graft-related complications, PEEK cage filled with DBM, and plate fixation provide a promising surgical option for treating traumatic subaxial cervical spine injuries.

Objective: This study was designed to evaluate the etiological factors of the PTSD(post traumatic stress disorder) by examining the relationship between severity of physical trauma and subsequent the severity of PTSD symptom in traffic accident related PTSD patients. Method: Subjects were 21 psychiatric inpatients with history of traffic accident related PTSD(DSM-IV criteria), the purpose of evaluation of mental disability and no evidence of organic brain leisons. The severity of physical trauma was assessed by McBride number of nonpsychiatric department and the presence / absence of loss of conciousness. The severity of PTSD symptom was assessed by Hovens' self rating inventory for PTSD. And then we evaluated the correlation between these two factors. And we also evaluated relationship between severity of PTSD symtom and clinical variables. Results : There were no significant relationship between McBride number of nonpsychiatric department severity and symptomatic severity(r= 0.17, p<0.05), the presence / absence of loss of conciousness and symptomatic severity(p>0.05). And significant relationship between symptomatic severity and clinical varibles such as sex, education level, marital status(p<0.05). Conclusions : These data did not support data of previous studies that traumatic severity was correlated with symptom severity but, suggested that other variables affecting the severity of PTSD symptom is more important indirectly. And that the 'trauma' in PTSD is psychological meaning rather than physical meaning is also suggested.

Objective : Cranioplasty using a cryopreserved skull flap is a wide spread practice. The most well-known complications of cranioplasty are postoperative surgical infections and bone flap resorption. In order to find biological evidence of cryopreserved cranioplasty, we investigated microorganism contamination of cryopreserved skulls and cultured osteoblasts from cryopreserved skulls. Methods : Cryopreserved skull flaps of expired patients stored in a bone bank were used. Cryopreserved skulls were packaged in a plastic bag and wrapped with cotton cloth twice. After being crushed by a hammer, cancellous bone between the inner and outer table was obtained. The cancellous bone chips were thawed in a water bath of $30^{\circ}C$ rapidly. After this, osteoblast culture and general microorganism culture were executed. Osteoblast cultures were done for 3 weeks. Microorganism cultures were done for 72 hours. Results : A total of 47 cryopreserved skull flaps obtained from craniectomy was enrolled. Of the sample, 11 people were women, and the average age of patients was 55.8 years. Twenty four people had traumatic brain injuries, and 23 people had vascular diseases. Among the patients with traumatic brain injuries, two had fracture compound comminuted depressed. The duration of cryopreservation was, on average, 83.2 months (9 to 161 months). No cultured osteoblast was observed. No microorganisms were cultured. Conclusion : In this study, neither microorganisms nor osteoblasts were cultured. The biological validity of cryopreserved skulls cranioplasty was considered low. However, the usage of cryopreserved skulls for cranioplasty is worthy of further investigation in the aspect of cost-effectiveness and risk-benefit of post-cranioplasty infection.

Objective: To evaluate the changes in bladder capacity and storage through non-invasive neuromodulation by application of repetitive Trans magnetic stimulation (rTMS) and genital nerve stimulation (GNS) in traumatic spinal cord survivors. Design: A Single Case Study. Method: The Patient was registered in trail with the clinical trial registry of India (CTRI/2022/05/042431). The Patient was interposed with rTMS on lumbar area, from T11-L4 vertebrae with 1 Hz and the intensity was 20% below that elicited local paraspinal muscular contraction for 13 minutes. GNS was placed over dorsum of the penis with the cathode at the base and anode 2 cm distally at 20 Hz, 200 microseconds, Continuous and biphasic current was delivered and amplitude of stimulation necessary to elicit the genito-anal reflex. For assessment, Neurological examination was done for peri-anal sensation (PAS), voluntary anal contraction (VAC) and bulbocavernous reflex (BCR), deep anal pressure (DAP), and American Spinal Injury Association Impairment Scale (ASIA scale). Outcome assessment was done using Urodynamics, Spinal Cord Independence Measure Scale Version-III (SCIM-III), American Spinal Injury Association Impairment Score (ASIA Score), Beck's Depression Inventory Scale (BDI). The baseline evaluation was taken on Day 0 and on Day 30. Results: The pre-and post-data were collected through ASIA score, SCIM-III, BDI and Urodynamics test which showed significant improvement in bladder capacity and storage outcomes in the urodynamics study across the span of 4 weeks. Conclusion: rTMS along with GNS showed improvement in bladder capacity & storage, on sensory-motor score, in functional independence of individual after SCI.
