이 연구에서는 건강한 성인 남성 12명이 참여하여 3종의 겨드랑이 목발(Mobilegs, KM crutch, Pro In-motion)을 사용한 보행에서 광배근과 비복근에서의 근전도 반응과 보행에서의 편안함과 사용 편이성을 중심으로 한 사용자 인식 평가 실험을 수행하였다. 실험 결과, 광배근에서는 목발 사이에 통계적으로 유의한 차이가 없지만 비복근에서는 Mobilegs와 Pro In-motion이 KM crutch에 비해 현저히 낮은 활성도를 보였다. 이것은 Mobilegs와 Pro In-motion은 각각 겨드랑이 받침대 하단과 목발 하단에 스프링이 장착되어 있어 비복근에 요구되는 힘이 적은 것으로 추론할 수 있다. 사용자 인식 평가에서 Mobilegs는 보행 시 편안함과 사용 편이성에 대해 모두 다른 목발들에 비해 현저히 높은 결과를 보였다. 이것은 목발 보행 시 많은 힘이 집중되어 다양한 문제를 유발시키는 겨드랑이 받침대와 손잡이의 디자인 때문으로 추론할 수 있다. 종합적으로 볼 때, 연구의 결과는 스프링이 장착된 목발을 이용한 보행에서 비복근에서 적은 힘이 요구되어 보다 쉬운 보행을 가능케 함을 보여준다. 또한 이러한 목발의 디자인 특성은 근육에 요구되는 힘을 줄이고, 여기에 겨드랑이 받침대와 목발 손잡이의 합리적인 구조와 형태가 보태질 경우 사용자들은 그 목발을 사용한 보행에서 전체적으로 매우 편안하게 인식함을 알 수 있다.

The purpose of this study was to determine the effect of systolic blood pressure, heart rate and myocardial oxygen consumption on 3-point nonweight bearing ambulation with axillary wooden crutch according to age. The subjects were fifty healty volunteers(22 male, 28 female), ages from 20 to 69(mean age of 43.8 years) with no history of cardiovascular or respiratory disease, diabetes mellitus, arthritis and orthopedic disorder within the past three years. This study was carried out from May 10 to August 10, 1996. The data were analyzed by percentage, mean and standard deviation and ANOVA. The results were as follows : 1. In systolic blood pressure(SBP), there was no significantly change between before walk and after 20 m in crutch walking with age, however, there did differ significantly after 40 m and 60 m in crutch walking(p<0.01, p<0.001). 2. In heat rate(HR), there was no significantly change between before walk and after 20 m, 40 m in crutch walking with age, however, there did differ significantly after 60 m in crutch walking(p<0.05). 3. In myocardial oxygen consumption($MVO_{2}$), there was no significantly change between before walk and after 20m in crutch walking with age, however, there did differ significantly after 40 m and 60 m in crutch walking(p<0.01, p<0.001). These result showed that cardiovascular system had a great effect on the olderly when 3-point nonweight bearing ambulation with axillary wooden crutch. Therefore, when train for axillary crutch in the olderly, we needed suitably basis of walking distance.

Purpose: An axillary crutch is the most commonly used assistive device in foot and ankle patients who require nonweightbearing. On the other hand, its use frequently induces axillary or wrist pain and critical neurovascular injuries have been reported in several studies. This study compared the clinical outcomes of patients using the knee walker and axillary crutch. Materials and Methods: A retrospective analysis was performed comparing the utility of a knee walker and axillary crutch as a nonweightbearing ambulatory aid for 62 foot and ankle patients treated between November 2016 and March 2018. A comparative study of the two orthosis could be performed because all the patients temporarily used an axillary crutch before or after the use of a knee walker. A demographic study and comparative analysis based on the visual analogue scale (VAS) satisfaction score (0~100), complications, and fall down history were evaluated. Furthermore, under the assumption of having retreatment, their preference of orthosis between the knee walker and axillary crutch was investigated. Results: The mean age of the patients was 36.5 and the mean duration of ambulation with a knee walker and axillary crutch were 5.2 and 2.4 weeks. The VAS satisfaction score of the knee walker and crutch was 88.8 and 27.5, respectively (p<0.05). The most frequent complications of the knee walker and crutch were ipsilateral knee pain (6 cases) and axillary or wrist pain (56 cases), respectively. No case of falling down occurred during knee walker ambulation, but there were two cases of crutch ambulation. Fifty-eight patients (93.5%) preferred the knee walker and four patients (6.5%) preferred a crutch. Conclusion: Compared to the axillary crutch, the knee walker afforded lower complication and higher satisfaction. Most patients preferred the knee walker to a crutch. Therefore, the knee walker is an efficient and safe orthosis for foot and ankle patients who require nonweightbearing.

Purpose: To evaluate the result of the early exercise and rehabilitation after limited posterior operative treatment of the calcaneal fractures. Materials and Methods: Between May 2005 and December 2007, 43 cases with intraarticular calcaneal fractures were treated by open reduction with K-wires and Steinmann pins. Mean age and mean follow-up period were 42.5 years old and 15 months. All patients were treated with the same postoperative protocol, the early exercise of subtalar joint without short leg splint and cast was began after postoperative 1 day, non-weight bearing crutch ambulation did after 2 weeks, partial-weight bearing crutch ambulation did after 6 weeks, without crutch ambulation did after 10 weeks. The fractures was classified by Essex-Lopresti and Sanders classification using radiographs and the functional outcomes were evaluated by circle draw exercise, AOFAS score. Results: By Essex-Lopresti classification, the tongue type was 6 cases (14%), the joint depression type was 15 cases (35%), the combined type was 22 cases (51%). By Sanders classification, type II were 10 cases (23%), type III were 15 cases (58%), and type IV were 8 cases (19%). By AOFAS functional evaluation, the mean preoperative scores were 70.3 and 70.5 respectively, mean postoperative scores were 83.7 and 86.9 respectively. There were satisfactory results in 40 cases but 3 cases were unsatisfactory including on case of lateral impingement and 2 cases of traumatic arthritis of subtalar joint. Conclusion: We obtained satisfactory result of the early exercise of subtalar joint without short leg splint and cast and rehabilitation after limited posterior operative treatment of the calcaneal fractures.

1. 저자들은 1986년 11월부터 1988년 2월까지 경골간부 골절 8례를 나사못 맞물림법을 이용한 골수강내 금속정을 사용하여 치료하였다. 2. 술 후 방사선 소견상 골유합 기간은 평균 약 15주였다. 3. 환자의 입원기간은 평균 5.5주로서 비교적 짧은 입원기간을 보여주었으며 아울러 사회복귀 및 적응이 빨랐다. 4. 술 후 조기운동이 가능하였고 평균 4.3주 경과 후 목발보행을 시작하였다. 5. 술 후 관절강직, 근위축등의 합병증은 거의 없었다. Hamza등에 의한 술후 평가방법에 따르면 Excellent 7례, Good 1례로 결과는 만족스러웠다.
