The aim of this study is to present the basic reference data of age and specific gait parameters for comparisons of the gait characteristics depended on amputation length of the Unilateral Trans-Tibial Prostheses. The basic gait parameters were extracted from 10 Adult, and 20 below knee(B/K) patients, 50 to 60 years of age using VICON 512 Motion Analyzer. The results were as follows; 1. The mean Cadence of the above knee(A/K) patients and below knee(B/K) patients were $87.77{\pm}8.64$ steps/min, to $99.84{\pm}11.14$ steps/min.(p<0.05) 2. The mean Walking Speed of the above knee(A/K) patients and below knee(B/K) patients were $0.84{\pm}0.15$ m/s, to $0.96{\pm}0.25$ m/s.(p>0.05) 3. The mean Stride Length of the above knee(A/K) patients and below knee(B/K) patients were $1.14{\pm}0.14\;m$, to $1.14{\pm}0.22m$.(p>0.05) 4. The mean maximal angles of joint on the hip flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $34.75{\pm}10.18_{\circ}$, to $32.32{\pm}6.34_{\circ}$.(p>0.05) 5. The mean maximal angles of joint on the knee flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $66.97{\pm}15.08_{\circ}$, to $52.65{\pm}9.21_{\circ}$. (p<0.05) 6. The mean maximal angles of joint on the ankle dorsi-flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $14.41{\pm}4.82_{\circ}$, to $10.04{\pm}3.49_{\circ}$.(p>0.05) 7. The mean maximal angles of joint on the ankle plantar-flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $5.77{\pm}3.17_{\circ}$, to $2.75{\pm}4.49_{\circ}$.(p>0.05)

The purpose of this study is to announce the present condition, walking training, and adaptable training of a limb amputated patient. The study is a successful report of the limb amputated patient through the medical treatment of the physical therapy. A cause of the limb amputated patient, a truck driver, was that the patient was hit by a train when the driver alight from the truck. Then, the driver was surgical operated on left AK (Above Knee) amputation and left AE (Above Elbow) amputation by orthopedics at the Young Dong Severance Hospital on Dec.7, 1996. Two weeks after the operation (Dec., 22, 1996), the patient was trained at the Yonsei Medical Center Physical Therapy Hospital for the walking and temper adjust training. It was possible to do a flat surface walking and a slope surface walking without helping due to the patients optimistic personal character and motivation. However, the patient struggled to a dull surface walking and his weak endurance. the patient has several problems when the patient wears artificial legs and hands, fears on fall down, and mentally worries on noise when he walks. It is necessary to approach for this problems by many fields of the helpers, such as Rehabilitation medical doctor, physical therapist, occupational therpist, artificial limbs makers, psychologists, and etc. Therefore, in order for recovering from the amputated parts function after the surgical operation, more approved reports have to be for the amputated patients due to increasing traffic accidents, industrial disaster, cancer, diabetes, obstacles of the peripheral nervous system, and etc.

의족과 절단단을 연결해주는 현가장치는 하지 절단 장애인이 의족착용을 가능하게 하며 보행뿐만 아니라 일상생활 중에서도 항상 절단단과 접촉되어 있어 의족 사용 중 가장 민감하게 느끼는 부분이다. 본 논문에서는 영구자석의 인력과 척력의 원리를 이용하여 자석의 극성변화로 하지 절단 장애인들의 절단단과 의족을 고정할 수 있는 자석락 현가장치를 개발하였다. 자석락의 작동 방식은 비자성체인 황동심을 기준으로 좌우에 네오디움 자석을 NNSS로 배치 시 자력은 흡착부재를 매개체로 하여 황동심을 넘어 외부로 흘러 결합력이 발생하며, 90도 회전 시 자석은 NSNS로 위치 이동하며 자력이 내부로 흘러 상쇄되는 원리이다. 이를 바탕으로 인장강도를 통한 결합력 시험 및 비교군인 셔틀락 현가장치와의 단기적인 의족 비교 평가를 수행하여 시제품에 대한 신뢰성 검증 및 만족도를 평가하였다. 그 결과 적정 결합력을 상회하는 인장강도를 확인하였으며 자석락이 셔틀락 대비 높은 만족도를 나타냈다. 추후 제품화를 위한 장기적인 ADL 임상시험을 수행해 실제 절단 장애인들에게 보급 가능한 제품으로 개발하고자 한다.
