Abstract
Background: After bilateral transfemoral amputation, people may experience limitations in everyday life due to limited mobility and prosthesis problems. Materials and method: The case study covered a 54-year-old man after bilateral traumatic amputation of his lower limbs. Transfemoral amputations were performed using the Caldwell method; disproportion in the length of stumps was 5 mm. The motion task was recorded using the SMART-E optoelectronic system (BTS Bioengineering, Milan, Italy) according to the standard Davis protocol (the Newington model). Biomechanical evaluation included the measurement of angle-time relationships, characterizing the range of motion (ROM) in lower limb joints and Ground Reaction Force (GRF). The analyzed tasks are walking with self selected speed, fast gait and walking in stubby prostheses. Results: Step width was the most similar to the gait of healthy persons walking with stubby prostheses (0.17 ± 0.01 m for healthy people, 29% higher for stubbies, 35% for prosthetic gait with self-selected gait speed and 41% for fast gait speed). Step width was the smallest when walking with stubbies. Conclusions: The reduction of body height allows to reduce the risk of fall. Higher metabolic cost of gait in people after amputation result from a greater need to maintain balance and posture, and to perform walking movement.
Highlights
The percentage of people who have undergone a double amputation above the knee joints (BTA—bilateral transtibial amputation) and use orthopedic products on a daily basis is low
The width whensuch walking with stubby prostheses ground reaction force, the parameterization was subjects performed by±calculating was most similar to the gait of healthy
The general health status and the state of the stump have an effect on the correctness and efficiency of the gait after a double transfemoral amputation [21]
Summary
The percentage of people who have undergone a double amputation above the knee joints (BTA—bilateral transtibial amputation) and use orthopedic products on a daily basis is low. The surgeon, as much as possible, tries to perform the amputation so that the remaining stump will be as highly functional as possible for the patient in terms of prosthesis fitting. The energy expenditure during the gait cycle increases up to 200% with double transfemoral amputation. Oxygen uptake increases, compared to 38–49% for unilateral amputees and up to 280% for bilateral amputees. The metabolic cost of the gait cycle and ambulatory physical activity are influenced by the amputation level and the number of amputated limbs [1]. The energy expenditure of the gait cycle after having undergone a double amputation above the knee joints is
