“…In a study that investigated the vascular-related LLA incidence rates among older adults in the United States from 1956 to 1995, the authors reported a decline in the LLA incidence rates but an increase in the total number of LLAs. 23 Likewise, Dawes et al reported similar findings for the LLA incidence rates in Quebec. 8 Consistent with previous reports from other regions, the calculated incidence rate of LLA was greater among males than females.…”

OBJECTIVES: To determine the Canadian age-adjusted incidence rates of lower limb amputation (LLA) by province, sex, level, and cause of amputation.METHODS: Data on all hospital discharges associated with LLA from April 1, 2006, to March 31, 2012, were obtained from the Canadian Institute for Health Information's Discharge Abstract Database. National and provincial age-adjusted rates were calculated per 100 000 individuals by sex, level, and cause of LLA using the direct method of standardization. The relative risk of LLA in people with diabetes was calculated.RESULTS: There were a total of 44 430 LLAs performed in Canada over the study years. The number of LLAs increased from 7331 in 2006 to 7708 in 2011. Mean (SD) age was 65.7 (16.6) years, and 68.8% were males. Sixty-five percent of the LLA cases were due to diabetes. The average age-adjusted rate of LLA in Canada was 22.9 per 100 000 individuals. The age-adjusted rates declined over the study years. The relative risk of diabetes-related LLAs was 28.9.CONCLUSION: This study provided the first Canadian national and provincial age-adjusted incidence rates of LLA and a baseline for monitoring and evaluation in the future. Understanding the incidence of LLA is essential to managing preventive and rehabilitation services for this population. Although the age-adjusted LLA incidence rates have decreased, the number of new LLAs has increased. The increase in the number of LLAs has important implications for social and health care costs.KEY WORDS: Incidence; epidemiology; amputation; diabetes; Canada La traduction du résumé se trouve à la fin de l'article.

“…Despite advances in medical care and an emphasis on prevention programs, studies have shown an increase in the overall prevalence of amputations secondary to vascular diseases and have predicted a doubling of the elderly amputation population by 2030 [4][5]. The care for this population has been predicted to require significant resources [4].…”

“…4,46 Many amputees rely on lower limb prostheses to regain some function of the missing limb, though their mobility, stability, and community participation remain substantially limited. 23 Compared to traditional energetically-passive devices, modern powered knee prostheses promise to restore more natural locomotion and provide greater functionality.…”

A Cyber Expert System for Auto-Tuning Powered Prosthesis Impedance Control Parameters

Typically impedance control parameters (e.g., stiffness and damping) in powered lower limb prostheses are fine-tuned by human experts (HMEs), which is time and resource intensive. Automated tuning procedures would make powered prostheses more practical for clinical use. In this study, we developed a novel cyber expert system (CES) that encoded HME tuning decisions as computer rules to auto-tune control parameters for a powered knee (passive ankle) prosthesis. The tuning performance of CES was preliminarily quantified on two able-bodied subjects and two transfemoral amputees. After CES and HME tuning, we observed normative prosthetic knee kinematics and improved or slightly improved gait symmetry and step width within each subject. Compared to HME, the CES tuning procedure required less time and no human intervention. Hence, using CES for auto-tuning prosthesis control was a sound concept, promising to enhance the practical value of powered prosthetic legs. However, the tuning goals of CES might not fully capture those of the HME. This was because we observed that HME tuning reduced trunk sway, while CES sometimes led to slightly increased trunk motion. Additional research is still needed to identify more appropriate tuning objectives for powered prosthetic legs to improve amputees' walking function.
