ObjectiveTo investigate the effects of early rehabilitation on function of patients undergoing complex lower limb amputation caused by injuring in "4·20" Lushan earthquake. MethodsFrom April 20th to June 30th, 2013, we carried out comprehensive rehabilitation intervention for two patients who had undergone complex lower limb amputation, including physical treatment, exercise treatment, psychological treatment, wound dressing, rehabilitation program, and multiple rehabilitation nursing care. ResultsThrough early comprehensive rehabilitation intervention, patients' pain was relieved, and their muscle strength, activities of daily living (ADL), and balance function had been improved greatly, achieving the goal of installing artificial limb. ConclusionEarly rehabilitation intervention treatment is effective in relieving pain in patients undergoing lower extremities amputation, and improving their muscle strength, ability of ADL and balance function, which can make the patients return to society much better and faster.
It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal individuals, but the relationship between lower limb amputation and the episodes of cardiovascular disease has not been studied from the perspective of hemodynamics. In this paper, numerical simulation was used to study the effects of amputation on aortic hemodynamics by changing peripheral impedance and capacitance. The final results showed that after amputation, the aortic blood pressure increased, the time averaged wall shear stress of the infrarenal abdominal aorta decreased and the oscillatory shear index of the left and right sides was asymmetrically distributed, while the time averaged wall shear stress of the iliac artery decreased and the oscillatory shear index increased. The changes above were more significant with the increase of amputation level, which will result in a higher incidence of atherosclerosis and abdominal aortic aneurysm. These findings preliminarily revealed the influence of lower limb amputation on the occurrence of cardiovascular diseases, and provided theoretical guidance for the design of rehabilitation training and the optimization of cardiovascular diseases treatment.
