Walking Ability of Unilateral Transtibial Amputees with Prostheses / 中国康复理论与实践

Objective To investigate walking ability of amputees with unilateral transtibial prosthesis. Methods From April to Decem-ber, 2016, 20 unilateral transtibial amputees (patients) and 20 healthy adults (controls) were tested with L test, balance test, 6-minute walk test (6MWT) and 1000 m walking outdoor on various terrain. Results There was no significant difference in time of L test between the am-putees wearing Solid Ankle Cushion Heel (SACH) and Storage Foot (t=0.675, P>0.05). In balance tests, there was no significant difference in the total track length, confidence ellipse area, maximum horizontal deviation and maximum vertical deviation between the patients and the controls (t0.05). Each parameter was significantly different in 6MWT between them (t>2.774, P4.130, P<0.001). Conclusion The walking ability of the unilateral transtibial ampu-tees wearing prostheses is different from normal people. The transtibial prosthetic feet that the amputees wear may impact their walking abil-ity.

Walking Ability of Amputees with Unilateral Transfemoral Prosthesis / 中国康复理论与实践

Objective To investigate the characteristics of walking ability of the amputees with unilateral transfemoral prosthesis. Meth-ods 16 unilateral transfemoral amputees (patients) and 16 healthy adults (controls) were tested with 6-minute walking test indoor, 1000 m walking outdoor on various terrain, balance test and energy expenditure test. Results The speed, frequency and stride length were significant-ly less in the patients than in the controls (P0.05). There were significant differences in time and energy expenditure of outdoor 1000 m walk test between two groups (P<0.05). There were significant differences in time of outdoor 1000 m walk test and distance of indoor walking test be-tween amputees wearing mechanical four-link prosthetic knee joint and fluid control prosthetic knee joint (P<0.05), but not in energy expen-diture of indoor and outdoor walking test. Conclusion The amputees with unilateral transfemoral prosthesis appear the inefficient in gait, and expend more energy. Their balance remains well. The transfemoral prosthesis the amputees wore may impact their walking ability.

Energy Expenditure of A Hemicorporectomy Amputee Moving with Different Mobility Devices / 中国康复理论与实践

Objective To compare the energy expenditure of a hemicorporectomy amputee moving with different mobility devices. Methods A middle-aged male hemicorporectomy amputee was measured with cardiopulmonary exercise test when moving with 4 kinds of transport:socket, cart, wheelchair, and prosthesis. Results The patient moved the slowest with prosthesis, fastest with wheelchair. The heart rate was the highest with prosthesis and lowest with cart. The absolute oxygen consumption, the relative volume of oxygen consumption and metabolic (Mets) were the most when hand walking with socket, and lowest with cart. Conclusion Hand walking with socket costs the larg-est energy when walking, and the rest are prosthesis, wheelchair, and cart.

Walking Ability of Bilateral Transtibial Amputees Assisted with Prostheses / 中国康复理论与实践

@#Objective To compare the walking ability between bilateral transtibial amputees and normal controls, and develope reference indexes of bilateral transtibial amptees' walking ability while wearing prostheses. Methods 11 bilateral transtibial amputees served as amputation group, 12 normal subjects served as controls. The indoor gait characteristics, outdoor time cost and energy consumption, and static balance of both groups were evaluated. Results After the indoor gait analysis, the average self-selected-speed of the amputees was 1.07 m/s, while the self-selected-speed of the normal people was 1.29 m/s. When the subjects walked with their self-selected-speed, there were significant differences in some of the gait spatial and temporal parameters between 2 groups (P<0.05). When the subjects walked on a specially designed 1 km outdoor trail, differences of energy consumption and time cost were also observed (P<0.05). Static balance presented no significant difference between 2 groups (P>0.05). Conclusion The walking ability of the bilateral transtibial amputees wearing prostheses is different from normal people. Quantitative evaluation of walking ability can provide more accurate reference for the rehabilitation of amputees.
