Purpose: Tumor infiltration around the knee joint or skip metastasis, repeated infection sequelae after tumor prosthesis implantation, regional recurrence, and mechanical failure of the megaprosthesis might require combined distal femur and proximal tibia replacement (CFTR). Among the aforementioned situations, there are few reports on the indication, complications, and implant survival of CFTR in temporarily arthrodesed patients who had a massive bony defect on either side of the knee joint to control infection. Materials and Methods: Thirty-four CFTR patients were reviewed retrospectively and 13 temporary arthrodesed cases switched to CFTR were extracted. All 13 cases had undergone a massive bony resection on either side of the knee joint and temporary arthrodesis state to control the repeated infection. This paper describes the diagnosis, tumor location, number of operations until CFTR, duration from the index operation to CFTR, survival of CFTR, complications, and Musculoskeletal Tumor Society (MSTS) score. Results: According to Kaplan-Meier plot, the 5- and 10-year survival of CFTR was 69.0%±12.8%, 46.0%±20.7%, respectively. Six (46.2%) of the 13 cases had major complications. Three cases underwent removal of the prosthesis and were converted to arthrodesis due to infection. Two cases underwent partial change of the implant due to loosening and periprosthetic fracture. The remaining case with a deep infection was resolved after extensive debridement. At the final follow-up, the average MSTS score of 10 cases with CFTR was 24.6 (21-27). In contrast, the MSTS score of 3 arthrodesis cases with failed CFTR was 12.3 (12-13). The average range of motion of the 10 CFTR cases was 67° (0°-100°). The mean extension lag of 10 cases was 48° (20°-80°). Conclusion: Although the complication rates is substantial, conversion of an arthrodesed knee to a mobile joint using CFTR in a patient who had a massive bony defect on either side of the knee joint to control infection should be considered. The patient's functional outcome was different from the arthrodesed one. For successful conversion to a mobile joint, thorough the eradication of scar tissue and creating sufficient space for the tumor prosthesis to flex the knee joint up to 60° to 70° without soft tissue tension.

This study was conducted to investigate the effects of participation in the accelerated rehabilitation with an anti-gravity treadmill program for 16 weeks on isokinetic myofunction and functional score of knee joint, ROM, and VAS score in meniscus repair patients. A total of 10 male adult patients who underwent meniscus repair by the same doctor were investigated in this study. Both extension and flexion peak torque at $60^{\circ}/sec$ and $180^{\circ}/sec$ significantly increased (p<0.001, p<0.01), while under muscle deficit, extension and flexion peak torque at $60^{\circ}/sec$ and extension peak torque at $180^{\circ}/sec$ significantly decreased (p<0.01, p<0.05). ROM in extension significantly decreased (p<0.05), whereas ROM in flexion significantly increased (p<0.01) in response to the program. VAS score significantly decreased (p<0.001) and lysholm scores significantly increased after completion of the program (p<0.001). These results suggest that 16 weeks of the anti-gravity treadmill accelerated rehabilitation program improves isokinetic muscle strength and functional score of knee joint, ROM, and VAS score in meniscus repair patients. Therefore, the anti-gravity treadmill accelerated rehabilitation program, which is a more scientific and effective method than conventional rehabilitation, leads to faster recovery of paly ground and normal daily activities.

Purpose : The purpose of this study was to provide information for developing a rehabilitation intervention that improves adaptation and the quality of life after mastectomy by investigating the level of physical function and fatigue in mastectomy patients. Methods : The subjects were 63 patients selected from St. Mary's Kangnam hospital Data were collected from March to June, 2003. Physical function was measured by the range of motion of the shoulder joint, shoulder function, and physical symptoms. fatigue was measured by using the Brief Fatigue Inventory (BFI). Results : The range of motion on the affected side was significantly lower than that in the healthy side. Shoulder function score was highest in the item of 'pull on pants', and lowest in the item of 'back zipper'. Physical symptom score was highest in the item of 'numbness', and lowest in the item of 'Itching sensation'. The highest item interfered by fatigue was 'normal work (includes both work outside the home and daily chores)'. Conclusion : The result of this study suggests that effective rehabilitation intervention for mastectomy patients should be needed to improve physical function, and reduce fatigue.

Patients with disabilities from various reasons such as disasters, injuries or chronic illness or elderly with limited body motion range due to aging are recommended to participate in rehabilitation programs at hospitals. But typically, it's not as simple for them to commute without help as they have limited access outside of the home. Also, regarding the perspectives of hospitals, having to maintain the workforce and have them take care of the rehabilitation sessions leads them to more expenses in cost aspects. For those reasons, in this paper, a home-based remote rehabilitation system using motion recognition is developed without needing help from others. This system can be executed by a personal computer and a stereo camera at home, the real-time user motion status is monitored using motion recognition feature. The system tracks the joint range of motion(Joint ROM) of particular body parts of users to check the body function improvement. For demonstration, total of 4 subjects with various ages and health conditions participated in this project. Their motion data were collected during all 3 exercise sessions, and each session was repeated 9 times per person and was compared in the results.

Hemiplegic patients who suffered from a stroke struggle with a deterioration in upper limb functions, which can both be psychologically and physically discomforting; this can also limit patients' daily tasks involving any upper limb motions. In this study, we developed an assistive device for hemiplegic patients to improve their upper limb functions. It was manufactured to train patients by using their grip strength and the range of motion of the arm. Furthermore, we produced game contents in virtual reality to induce users' immersion and interaction. It was configured as a multi-player game to help ease the mental burden of receiving the training alone, hence allowing the patient and the caregiver to join the rehabilitation training simultaneously. The assistive device and game contents developed in this study enables patients and caregivers to easily check the degree of improvements in upper limb function by viewing quantitative analysis and visualized results.

Type I, II, III are regarded as "true" joint receptors, type IV is considered a class of pain receptor. Type I, II and III mechanoreceptors, via static and dynamic input, signal joint position, intraarticular pressure changes, and the direction, amplitude, and velocity of joint movements. Type I mechanoreceptor subserve both static and dynamic physiologic functions. Type I are found primarily in the stratum fibrosum of the joint capsule and ligaments. Type I receptors have a low threshold for activation and are allow to adapt to changes altering their firing frequency. Type II receptors have a low threshold for activation. These dynamic receptors respond to joint movement. Type II receptors are thus termed rapidly adapting. Type II joint receptors are located at the junction of the synovial membrane and fibrosum of the joint capsule and intraarticular and extraarticular fat pads. Type III receptors have been found in collateral ligaments of the joints of the extremities. Morphologically similar to Golgi tendon organ. These dynamic receptors have a high threshold to stimulation and are slowly adating. Type IV receptors possess free nerve ending that have been found in joint capsule and fat pads. They are not normally active, but respond to extreme mechanical deformation of the joint as well as to direct chemical or mechanical irritation. Small amplitude oscillatory and distraction movements(joint mobilization) techniques are used to stimulate the mechanoreceptors that may inhibit the transmission of nociceptors stimuli at the spinal cord or brain stem levels.

Non-specific chronic neck pain (CNP) is a prevalent disorder and often accompany with pain, fatigue, reduced range of motion (ROM), and hand function. Although various types of drug are commonly used to manage the symptoms following CNP, there is a need for therapeutic exercise and alternative medicine interventions that have few side effects or are easy to apply. Present study investigated the effects of salt pack and neck exercise for life care of the elderly with non-specific CNP. Sixteen patients with non-specific CNP were recruited and randomly assigned into two groups: the intervention group (n=8) or the control group (n=8). All patients performed neck self-exercise for 30 min/day, 5 times a week for 1 week. And the subjects in the intervention group additionally received salt hot pack for 20 min per session. Visual analogue scale (VAS) and pain pressure threshold (PPT) using algometer were used to assess pain intensity (primary outcome). ROM of shoulder joint and grip strength were measured to test shoulder and hand function (secondary outcome). There were significant improvements in the intervention group (p<.05), while the subjects in the control group did not show a significant change after intervention (p>.05). Also, the intervention group show significant differences in VAS and PPT compared to the control group (p<.05). Thus, our results demonstrated that salt pack and neck exercise have a positive effect for life care in elderly patients with non-specific CNP.

본 연구의 목적은 손 기능에 문제가 있는 환자들을 중심으로 splint의 효과를 알아보기 위한 기초조사로써 2명의 환자를 제주 한마음병원(Case1, 2)에서 2001년 6월부터 11월까지 조사하였다. 2명의 환자는 다음과 같다. i) 사례 1 : 뇌성마비 아동(4세, 남, 오른손)으로 한쪽 손목과 엄지손가락에 강직으로 인하여 잡기 기능에 제한이 있는 편마비 아동이다. ii) 사례 2 : 전기화상(56세, 남, 왼손)으로 4-5번째 손가락의 M.P joint와 I.P joint에 관절운동 제한으로 완전하게 주먹을 질 수가 없다. 연구를 위하여 손 기능의 평가는 표준화가 되어있는 Jebsen-hand function test, Total passive Motion(TPM)을 사용하였으며, 환자들의 만족도를 알아보기 위해서는 Canadian Occupational Performance Measure(COPM)을 사용하였다. i) 사례 1 : 두 가지 splint를 적용하였다. 즉 낮 동안에는 splint 1, 밤 동안에는 splint 2를 6시간 이상 착용하도록 하였으며 작업치료는 시행하지 않았다. ii) 사례 2 : 이 환자에게는 작업치료가 끝나는 동시에 splint. 3을 6시간 이상 착용하도록 하였으며, M.P joint와 I.P joint의 관절 변화를 조절하도록 특별히 고안된 splint를 적용하였다. 그 결과 사례 1의 Jebsen-hand function test시 초기에는 측정을 할 수가 없었으나, splint착용 후 크고 가벼운 물건 옮기기(44.15), 크고 무거운 물건 옮기기(42.66), 적목쌓기(44.63), 먹기 흉내내기(54.47) 등에서 처음 동작만 도와주면 측정이 가능할 수 있도록 진전을 보였다(그래프1), 사진(착용 전과 착용 후). 사례 2의 경우 Jebsen-hand function test의 적목쌓기와 먹기 흉내기가 가장 높았으며, 글씨 쓰기가 가능했다. 손의 관절가동 변화에서도 splint 착용전의 측정치와 착용 후 관절 가동 범위의 변화 폭이 약 $30_{\circ}$이를 보여주었다(그래프 2), (그래프3). 결론적으로 손 기능 회복에 직접적인 재활 치료뿐만 아니라, 치료 후에도 splint를 착용하여 가정에서도 계속적인 치료가 될 수 있도록 하는 것이 손의 기능회복에 도움이 됨을 알 수 있었다. 그러므로 각 환자의 문제점을 파악하여 적절한 splint를 제작해 줄 필요가 있다고 사료된다. 이 기초조사를 시작으로 하여 더 많은 환자들을 대상으로 splint가 손 기능 회복에 어떠한 영향을 미치는지 그 효과에 대하여 계속적인 연구가 필요할 것이다.
