Purpose: The author evaluated the clinical and radiological results after wearing the medial arch supports in children. Materials and Methods: 103 patients who had symptomatic flat feet were evaluated from march, 2002 to may 2009. All patients wore the medial arch supports according to the symptoms. We measured parameters at weight-bearing radiographs before and after medial arch support were worn. We also evaluated the clinical scores using the AOFAS score. Results: Mean age of patients was 97 months (11-204 months), all foot of patients involved bilaterally. Mean talo-first metatarsal angle of right foot was $17.7{\pm}9.4$ and left foot was $19.96{\pm}9.5$ degrees at AP radiograph in pre-wearing state. Mean calcaneal pitch angle of right foot was $12.0{\pm}5.3$ and left foot was $11.9{\pm}5.8$ degrees at lateral radiograph in pre-wearing state. Mean talo-first metatarsal angle of right foot was $14.4{\pm}8.05$ and left foot was $13.1{\pm}8.77$ degrees at AP radiograph in post-wearing state. Mean calcaneal pitch angle of right foot was $16.4{\pm}5.75$ left foot was $16.5{\pm}5.6$ degrees at lateral radiograph in post-wearing state. The radiographic angles between pre-wearing and post-wearing state were statistically significant (p<0.05). Mean pre-wearing AOFAS hindfoot score was $66.7{\pm}9.25$, midfoot score was $60.0{\pm}9.34$ forefoot score was $57.1{\pm}11.8$. Mean post-wearing AOFAS hindfoot score was $73.2{\pm}9.73$, midfoot score was $68.1{\pm}10.1$, forefoot score was $67.2{\pm}11.4$. The forefoot score was highest improving scores among the AOFAS scores. Conclusion: From our study, we concluded that medial arch support was effective for symptomatic flat feet of children in radiological and clinical results from our study.

신체의 이동과 정지 시 동적 안정성과 균형성에 영향을 미치는 인솔에 대해 분석하였다. 특히 종족궁의 아치를 인위적으로 서서 체중을 가한 상태와 같은 평상시와 동일한 상태로 지속적으로 지지하였을 경우에 개별적인 균형능력의 변화를 추적하였다. 정상적인 신체 조건과 발모양을 유지하는 20대 남녀 각 10명씩 20명을 대상으로 종족궁 내측아치를 측정하여 아치를 지지하는 인솔을 개별적으로 제작하였으며, Tetrax 균형성 평가 장비를 이용하여 COP의 변위 패턴과 힘점의 이동거리를 착용 전, 후 비교하였다. 아치를 지지하는 인솔을 착용한 실험군이 균형능력 평가에서 약 22% 정도 상승되는 결과를 나타내었다. 본 비교 실험을 통해 종족궁의 내측아치를 지지하는 인솔 착용이 신체의 균형능력을 향상시키는데 도움이 되는 것으로 나타났다.

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.
