Spinal pain is a common patient complaint in clinical practice. Conservative treatment methods include oral medication, physical therapy, injections, and spinal orthoses. The clinical application of orthoses is debated because of potential complications associated with long-term use, such as muscle weakness and joint contracture. We reviewed the orthoses most frequently used to manage spinal pain. We review the use of soft cervical and Philadelphia collars, lumbosacral corsets, and thoracolumbosacral orthosis to manage spinal pain. Spinal orthoses can help reduce pain by protecting the muscles and joints of the injured spinal region, preventing or correcting malformations, and limiting trunk flexion, extension, lateral flexion, and rotation. The short-term use of spinal orthoses is known to improve pain and disability during the treatment period without significant adverse effects. Spinal orthoses are expected to alleviate pain and improve patients' lifestyle.

Background: The aim of this study was to investigate the current state of the assistive devices and appliances provision system for cerebral palsy patients registered with brain disability. Methods: From 2003 to 2013, we analyzed the records of cerebral palsy patients who had assistive devices and appliances provisioned at least once in their lives based on National Health Information Database. Patients with cerebral palsy were divided into three groups: infants and toddlers, school age and adolescence, and adults. Results: Data on short leg plastic orthoses, ankle joint orthoses, and wheelchair were mainly analyzed. The types of ankle joint orthoses divided into three categories: limited, $90^{\circ}$ limited, and Klenzac. Limited ankle joint orthoses was most frequently supported of the three in all age groups. Powered wheelchair and scooter were most supported to adult patients. When the re-supply duration was evaluated, the duration was suitable to the duration on guideline of regulation of re-supplement according to the related laws in adult patients but not in infants/toddlers and school age/adolescence as the actual re-supplement duration was much shorter than the reference value. Conclusion: This study confirmed the pattern of assistive devices and appliances supply differed depending on the age of cerebral palsy patients.

Background: Hallux valgus (HV) is a foot deformity developed by mediolateral deviation of the first metatarsophalangeal joint. Although various foot-toe orthoses were used to correct the HV angle, verification of the effects of kinetics variables such as ground reaction force (GRF) through three-dimensional (3D) gait analysis according to the various type of orthoses for HV is insufficient. Objects: This study aimed to investigate the effect of soft and hard types of foot and toe orthoses to correct HV deformity on the GRF in individuals with HV using 3D motion analysis system during walking. Methods: Twenty-six subjects participated in the experiment. Participants had HV angle of more than 15° in both feet. Two force platforms were used to obtain 3D GRF data for both feet and a 3D motion capture system with six infrared cameras was used to measure exact stance phase point such as heel strike or toe off period. Total walk trials of each participant were 8 to 10, the walkway length was 6 m. Two-way repeated measures ANOVA was used to determine the effects of each orthosis condition on the various GRF values. Results: The late anteroposterior maximal force and a first vertical peak force of the GRF showed that the hard type orthosis condition significantly increased GRF compared to the other orthosis conditions (p < 0.05). Conclusion: There were significant effects in GRF values when wearing the hard type foot orthosis. However, the hard type foot orthosis was uncomfortable to wear during walking. Therefore, it is necessary to develop a new foot-toe orthosis that can compensate for these disadvantages.

The purpose of this study was to critically review biomechanical studies on foot orthoses (FO) in normal and diseased foot and provide beneficial information obtained from researches until now and future researching focus. The search was performed by Medline and Embase database including studies published in English from January 1980 to April 2007. The searching terms were foot orthoses, foot orthotics, insoles and shoe insert. 57 studies including 54 journal articles and 3 abstracts were finally selected under the conditions of having clinical trials, FO, control condition, movement, scientific measuring system. The reviewed studies were divided into 10 categories according to subject characteristics; healthy normal, excessive pronation or flexible flat foot, rheumatoid arthritis, diabetes, medial knee osteoarthritis, forefoot varus, plantar fasciitis, patellofemoral syndrome, cavus foot and finite element model. In summary, first, soft and semirigid FOs with some degree of cushioning showed much higher comfort and efficacy than rigid FO. Second, no big differences between prefabricated and custom FO were shown. Third, the full length's FO was preferable to the half length's FO or simple arch supports. Fourth, the wearing of FO combining medial arch supports and metatarsal dome made positive roles to enhance comfort and functionality and redistribute plantar pressure under the foot. Fifth, for patients with knee-related diseases lateral wedges were preferable. Sixth, measuring systems were properly applied according to the types of foot diseases.

This study aimed to evaluate factors related to the ability of ambulatory patients with cerebral palsy (CP) to walk over vertical and horizontal obstacles. Twenty patients with spastic CP who were able to walk independently for at least 10 m with or without walking devices were recruited for the study. Participants were required to walk over small obstacles (1, 4, and 8 cm in height or width; total of 6 conditions). A 'fail' was recorded when either the lower limbs or the walking device contacted the obstacle. Linear regression analyses were used to determine the effects of age, sex, walking devices, eyeglasses, subtype (hemiplegia or diplegia), ankle foot orthoses, functional level, and score of body mass index on the ability of obstacle crossing. Fifteen participants (75%) failed to adequately clear the foot or walking device over obstacles in at least 1 condition. The chance of failure in crossing vertical obstacle was affected by the use of ankle foot orthoses, eyeglasses, gender, and CP subtype (p<.05). The failure rate crossing horizontal obstacle was affected by CP subtype. These findings suggest that rehabilitation procedures should (1) consider the clinical characteristics of patients in order to prepare them to be more independent while performing daily activities, and (2) incorporate environmental conditions that patients encounter at home and in the community.

본 논문은 무릎보조기의 벨크로 및 잠금장치 강도에 대한 품질시험을 통해 향후 무릎보조기 품질 향상을 위한 기초자료를 제공하고자 하는 목적으로 진행되었다. 본 연구에서는 사용자의 선호도가 높은 3가지의 무릎보조기를 대상으로 국내 표준화 규격인 KS K 1309의 인장 및 박리강도 시험, KS P 8408의 정적 굽힘 시험과 KS P 8411의 잠금장치강도시험을 인용하여 진행하였다. 연구 결과 KS K 1309에 의거하여 진행한 벨크로 인장 강도 및 박리 강도 시험은 모두 기준에 만족하는 결과 값이 나왔으나 KS P 8408을 인용한 정적 굽힘 시험의 경우 B(1,704.8 N) 검체를 제외한 A(865 N), C(833.3 N) 검체는 기준치(1,000 N)에 적합하지 않은 결과가 나타났으며, KS P 8411을 인용하여 진행한 잠금장치강도시험의 경우 A(41.9 N), B(97.4 N), C(54.8 N) 모든 검체에서 인용규격 기준치(200 N)에 부족한 결과가 관찰되었다. 결론적으로 국내 무릎보조기에 대한 공인된 규격 및 체계적인 시험검사 체계 운영이 부족하여 품질관리 측면에 문제점이 많은 것으로 시사되며 이 결과는 향후 무릎보조기의 품질 향상 및 잠금장치 강도에 대한 시험방법 개발과 국내 표준화 절차 초기 단계의 기초 데이터로 무릎보조기의 평가 기반을 구축하는데 유용하게 적용 가능할 것으로 기대된다.
