Objective : Rheumatoid arthritis (RA) is known to involve the cervical spine up to 86%. It often causes cervical instability like atlantoaxial subluxation (AAS), subaxial subluxation, and vertical subluxation (VS). In order to find the relation between RA and cord compression, we will evaluate the characteristics and risk factors of basilar invagination (BI) and cervicomedullary junction (CMJ) compression. Methods : From January 2007 to May 2015, 12667 patients administrated to Hanyang University Medical Center. Four thousand three hundred eighty-six patients took cervical X-ray and 250 patients took cervical computed tomography or magnetic resonance imaging. Radiologic parameters, medication records were obtained from 242 patients. Multivariate logistic regression analysis was performed with correlation of CMJ compression, basin-dental interval (BDI), basin-posterior axial line interval (BAI), pannus formation, BI, and AAS. Results : In the point of CMJ compression, atlantodental interval (ADI), posterior-atlantodental interval, BAI, AAS, and BI are relatively highly correlated. Patients with BI have 82 times strong possibility of radiologic confirmed CMJ compression, while AAS has 6-fold and pannus formation has the 3-fold possibility. Compared to the low incidence of BI, AAS and pannus formation have more proportion in CMJ compression. Furthermore, wrist joint erosion was correlated with VS and AAS. Conclusion : BI has a very strong possibility of CMJ compression, while AAS and pannus formation have a high proportion in CMJ compression. Hence bilateral wrist joint erosion can be used as an indicator for the timing of screening test for cervical involvement. We suggest the early recommendation of cervical spine examination for the diagnosis of cervical involvement in order to prevent morbidity and mortality.

Objectives: Ganglion cysts require a sustainable treatment that suppresses their frequent recurrence. This study aimed to explore the clinical effects of Scolopendra pharmacopuncture (SP) and electroacupuncture on ganglion cysts. Methods: We retrospectively reviewed the patient records and follow-up reports for 20 patients with wrist ganglion cysts who received SP and electroacupuncture from April 2016 to March 2017. The cyst diameter, recurrence, visual analog scale (VAS) scores for pain, the Korean version of the disabilities of arm, shoulder, and hand (K-DASH) score, and the Korean version of the patient-rated wrist evaluation (K-PRWE) score before and after treatment were noted. Results: After treatment, the cyst diameter decreased significantly from 13.61 ± 6.41 mm to 5.15 ± 6.18 mm (p < 0.001), and VAS score for pain decreased from 1.31 ± 1.77 to 0.41 ± 0.33 (p = 0.021). Further, the K-DASH score decreased significantly from 8.97 ± 12.66 to 2.21 ± 7.39 (p = 0.016), and score for the function subscale of K-PRWE decreased from 11.37 ± 4.48 to 9.1 ± 3.67 (p = 0.046). No recurrences were reported from the followed-up patients. Any complication related to SP or electroacupuncture was not observed, except mild rash, itching, and swelling at the injection site in four patients. Conclusion: Combination of SP and electroacupuncture may be effective in treating ganglion cysts; further prospective studies with large population are needed to clarify the effect of SP and electroacupuncture.

Engagement is an important factor in the field of rehabilitation as it is a known factor that have a positive influence on functional gaining in people who receive rehabilitation therapy. Although a number of measurements for engagement have been recently developed, investigation of possible factors that may have influence on engagement is not well established. Currently available evidence suggests that engagement is affected by mood and it is hypothesized that a personal factor may contribute to engagement. Therefore, this study aims to test the hypothetical relationship between mood and engagement while performing a manual dexterity task through an experiment in healthy participants prior to investigation on people with medical condition who requires rehabilitation therapy. After inducing target mood (positive or negative mood) for study participants by asking them to recall autobiographical memories, change in muscle activity, which was operationalized as an indicator of engagement, was investigated. Electromyogram (EMG) was recorded from four muscle areas in non-dominant hand side to quantify muscle activity. The results show that the target moods were appropriately induced with the method. Although there were subtle differences in the level of engagement between different moods, certain variables derived from muscle activity were significantly different; mean amplitude for wrist extensor EMG showed significant difference between different moods (Z = -2.023, p < .05) indicating that muscle activities in the wrist extensor are greater for positive mood than negative mood region during manual dexterity task. Meanwhile, performance outcomes of Minnesota Manual Dexterity Test (MMDT), such as mean completion time and number of errors, between moods showed no significant difference in two different moods, resulting in MMDT administration may not be useful task in distinguishing the level of rehabilitation engagement.

The purpose of this study was to develop a hand rehabilitation training system for hemiplegic patients. We also tried to find out five hand postures (WF: Wrist Flexion, WE: Wrist Extension, BG: Ball Grip, HG: Hook Grip, RE: Rest) in real-time using multi-channel EMG-based deep learning. We performed a pre-processing method that converts to Spider Chart image data for the classification of hand movement from five test subjects (total 1,500 data sets) using Convolution Neural Networks (CNN) deep learning with an 8-channel armband. As a result of this study, the recognition accuracy was 92% for WF, 94% for WE, 76% for BG, 82% for HG, and 88% for RE. Also, ten physical therapists participated for the usability evaluation. The questionnaire consisted of 7 items of acceptance, interest, and satisfaction, and the mean and standard deviation were calculated by dividing each into a 5-point scale. As a result, high scores were obtained in immersion and interest in game (4.6±0.43), convenience of the device (4.9±0.30), and satisfaction after treatment (4.1±0.48). On the other hand, Conformity of intention for treatment (3.90±0.49) was relatively low. This is thought to be because the game play may be difficult depending on the degree of spasticity of the hemiplegic patient, and compensation may occur in patient with weakened target muscles. Therefore, it is necessary to develop a rehabilitation program suitable for the degree of disability of the patient.

Purpose : The purpose of this study was to investigate the effects of Kaltenborn-Evjenth (KE) joint mobilization of the distal radioulnar joints (RUJ) and proximal RUJ in distal radius fractures (DRFs) on range of motion (ROM), grip strength (GS), and patient-written wrist evaluation (PRWE) in each group once, thrice, or fivefold. Methods : Forty-two subjects participated in this study. We divided the subjects with DRFs into groups applying KE concepts RUJ mobilization once, thrice, and fivefold. The patients' ROM and GS were measured using a joint goniometer and dynamometer, respectively. Pain and function were also assessed using a PRWE. In the statistical analysis, all data were tested for normality using the Shapiro-Wilk test, and paired t-tests were performed for within-group before-and-after comparisons of each intervention. One-way analysis of variance was used for between-group comparisons of differences. All statistical significance levels were set at α=.05. Results : There were significant differences in the ROM in all three groups before and after the intervention (p<.05), but there were no significant differences between the groups. There were significant differences in the GS in the three groups before and after the intervention (p<.05), but there were no significant differences between the groups. In the pain part of the PRWE, all three groups had significant differences before and after intervention (p<.05), but there was no significant difference between the groups. In the functional part of the PRWE, there were significant differences in the three groups before and after intervention (p<.05), but no significant difference occurred between the groups. Conclusion : Based on the aforementioned results, there were no significant between-group differences in ROM, GS, and PRWE (pain and function) after the application of the K-E joint mobilization to DRFs once, thrice, and fivefold. Nevertheless, there were significant within-group differences in all the above.

Purpose: The purpose of this study was to investigate the relationships between job stress and work-related musculo-skeletal symptoms among nurses working in general hospitals. Method: A descriptive correlational research design was utilized. The participants were 438 nurses currently working in 4 general hospitals. Data were collected from Jan 2007 to Feb 2007, with Korean Occupational Stress Scale(KOSS)-basic form, KOSHA code H-30 and a questionnaire for general characteristics. Descriptive statistics, t-test, ANOVA, multiple logistic regression analyses were utilized. Result: Most participants(90.4%) complained of work-related musculo-skeletal symptoms. However, symptomatic nurses satisfying NIOSH screening criteria(symptomatic nurses) were 66.9%(293 persons). The most complained body part was back(39.5%). shoulder(37.7%), leg and foot(36.5%), wrist and hand(21.7%), neck(18.7%), and arm(9.8%). The mean of total score of occupational stress was 51.11. In multiple logistic regression analyses, age, working posture and total score of occupational stress showed significant associations with back symptoms. Exercise and total score of occupational stress were significantly related with shoulder symptoms. Hours of daily house keeping and working posture were related with leg and foot symptoms. Marital status and working posture were related with wrist and hand symptoms. Working posture only showed significant relations with neck symptom. Marital status, hours of daily house keeping, shift work, working posture, and total score of occupational stress were related with the symptoms in the arm. In conclusion, job stress of nurses might be related with work-related musculo-skeletal symptoms.

목 적：폐쇄성 수면무호흡증은 흔한 질환으로 심혈관계 합병증이나 주간 졸림증 때문에 점점 더 큰 관심을 끌고 있다. 수면무호흡증 진단에 야간 수면다원기록법이 표준검사로 인정되고 있으나 비교적 고가의 검사비용과 검사시 각종 감지기 등을 부착하고 인위적 환경인 검사실에서 잠을 자야 하는 불편함이 있다. 따라서 수면다원기록법을 대치할 수 있는 약식 검사들이 개발되고 있으며 그 중 대표적인 것이 손목부착형 활동기록기이다. 이 연구에서는 활동기록기가 수면무호흡증 진단에 어떤 보조적인 역할을 할 수 있는지를 수면분절의 관점에서 측정해 분석하였다. 방 법：폐쇄성 수면무호흡증이 의심되어 서울대학교병원 수면다원검사실로 의뢰된 37명의 환자들에게 야간수면다원검사와 동시에 활동기록기를 착용시켜 자료를 수집하였다. 전체 연구대상자 37명 중 폐쇄성 수면무호흡증 외에 주기성 사지 운동 등 다른 수면질환이 함께 진단된 10명의 환자를 제외한 27명의 자료를 분석하였다. 수면다원검사로 얻은 호흡장애지수(respiratory disturbance index, RDI)와 활동기록기의 자료분석으로 얻은 수면분절지수(fragmentation index, FI)를 Pearson 상관관계분석을 이용하여 비교하였다. 결 과：야간수면다원검사로 얻어진 총 수면시간, 호흡장애지수, 활동기록기로 산출된 수면분절지수는 각각 $401.37{\pm}57.83$분, $21.67{\pm}20.41$회/시간, $21.87{\pm}12.96$회/시간 이었다. 수면분절지수는 호흡장애지수와 유의한 양의 상관관계를 보였다(r=0.553 p=0.003). 결 론：수면분절지수가 호흡장애지수와 유의한 양의 상관관계를 보였다. 손목부착형 활동기록기는 수면무호흡증의 진단에 보조적인 도구로 이용될 수 있으며, 수면무호흡증의 각종 치료 후 증상 변화에 대한 평가용으로는 더 적극적인 역할을 할 수 있을 것으로 기대한다.
