Abstract
The aim of this study is to gain insight in the cardiorespiratory fitness of persons with lower limb amputation (LLA) during rehabilitation, and in potential factors influencing their cardiorespiratory fitness. We performed a retrospective cohort study using data from cardiopulmonary exercise tests. Included participants were adults with LLA. Main outcome was cardiorespiratory fitness expressed as O 2 peak (ml/min/kg) and was directly determined using breath-by-breath gas analysis. O 2 peak was compared to reference values for able-bodied controls. Multivariate regression analysis was performed to investigate potential factors related to O 2 peak in persons with LLA. Potential factors were age, BMI adjusted, gender, level of amputation, aetiology of amputation, unilateral/bilateral, type of ergometry and use of beta blockers. Data of 74 participants with LLA are presented; 84% male (n = 62), mean age 58.9 (SD 11.6), mean BMI 26.7 (SD 5.6), 44 participants have a LLA above the knee, 30 below the knee. Overall O 2 peak was lower in persons with LLA compared to reference values for able-bodied controls, with mean O 2 peak for the total LLA group of 14.6 ± 4.1 ml/kg/min. In the multivariate regression analysis, only age was a significant predictor for lower O 2 peak (regression coefficient: -0.15, 95% CI [0.23-0.069], r 2 = 0.166). These results indicate that the cardiorespiratory fitness in persons with LLA is low, while they actually need more energy to walk and perform other daily activities. Cardiorespiratory fitness is not closely associated with the analysed demographic or clinical factors and will have to be determined on an individual basis for use in daily practice.
期刊介绍:
International Journal of Rehabilitation Research is a quarterly, peer-reviewed, interdisciplinary forum for the publication of research into functioning, disability and contextual factors experienced by persons of all ages in both developed and developing societies. The wealth of information offered makes the journal a valuable resource for researchers, practitioners, and administrators in such fields as rehabilitation medicine, outcome measurement nursing, social and vocational rehabilitation/case management, return to work, special education, social policy, social work and social welfare, sociology, psychology, psychiatry assistive technology and environmental factors/disability. Areas of interest include functioning and disablement throughout the life cycle; rehabilitation programmes for persons with physical, sensory, mental and developmental disabilities; measurement of functioning and disability; special education and vocational rehabilitation; equipment access and transportation; information technology; independent living; consumer, legal, economic and sociopolitical aspects of functioning, disability and contextual factors.
