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.
Aiming at motion artifacts and off-resonance artifacts in multi-shot diffusion magnetic resonance imaging (MRI), we proposed a joint correction method in this paper to correct the two kinds of artifacts simultaneously without additional acquisition of navigation data and field map. We utilized the proposed method using multi-shot variable density spiral sequence to acquire MRI data and used auto-focusing technique for image deblurring. We also used direct method or iterative method to correct motion induced phase errors in the process of deblurring. In vivo MRI experiments demonstrated that the proposed method could effectively suppress motion artifacts and off-resonance artifacts and achieve images with fine structures. In addition, the scan time was not increased in applying the proposed method.
