Background. Information concerning exercise tolerance and aerobic capacity is imperative for generating effective and safe exercise programs. However, for older people with a lower-limb amputation, a standard exercise test is not available. Objective. The primary aim of the present study was to determine whether a graded 1-legged peak exercise test is feasible and provides a valid assessment of peak aerobic capacity in older people walking with a lower-limb prosthesis. Design. This was a quasi-experimental case-control study. Methods. a total of 36 older people with a lower-limb prosthesis and 21 people who were able-bodied (controls) (overall mean age=61.7 years, SD=6.1) performed a discontinuous graded 1-legged exercise test. The peak respiratory exchange ratio was used as an indicator of maximal effort. The controls performed an additional 2-legged exercise test to provide insight into differences between the testing modes. Results. MI participants were able to perform the exercise test. Electrocardiographic tracings and blood pressure were adequately monitored. The controls and the people with a lower-limb amputation were able to stress the cardiovascular system to a similar extent. Analyses of construct validity revealed that the peak aerobic capacity measured with the 1-legged exercise test was able to distinguish between participants on the basis of age, body mass index, and sex to a similar extent as the conventional 2-legged exercise test. Limitations. The results can be generalized only to people who are able to ambulate with their prosthesis. Conclusions. The graded 1-legged exercise test was feasible and provided a valid assessment of peak aerobic capacity and exercise tolerance in older people walking with a lower-limb prosthesis., Graded exercise testing has been widely acknowledged and implemented as a valid and effective way to assess physical fitness, diagnose coronary artery disease, allow for risk stratification, (1,2) and determine [...]

Background and Purpose. Gait training is an important component of rehabilitation after lower-extremity amputation. Abnormal gait performance often persists even for individuals who reacquire a high level of function. This case report describes the use of a virtual reality (VR)-based gait training program that provides real-time feedback in order to improve biomechanical and physiological performance. The aim of this case report is to describe the effects of the training in a person with a transfemoral amputation. Case Description. A 24-year-old man with a transfemoral amputation completed a 3-week gait training program. The intervention consisted of 12 sessions of treadmill walking with real-time visual feedback on full-body gait kinematics. A treating therapist directed the patient's attention to specific gait deviations as a means to normalize gait biomechanics. Outcomes. The patient completed overground biomechanical gait analyses and multiple-speed treadmill tests 3 weeks apart prior to and following the training program. Biomechanical gait analyses indicated the training produced improved frontal-plane hip, pelvis, and trunk motion during overground walking. Improvement in trunk motion was observed at the posttraining test, and improvements in pelvis and hip motion were observed at the 3-week follow-up test. Decreases of up to 23% in oxygen consumption also were demonstrated. Discussion. Although the exact contribution of the visual feedback could not be isolated, the training was effective in improving the patient's walking performance. Biomechanical data suggest correcting trunk motion and increasing hip abductor strength (force-generating capacity) may be important in facilitating improvements at the pelvis and hip. Observed improvements in oxygen consumption were significantly larger than achieved through previously reported interventions., Approximately 60,000 transtibial and transfemoral amputations are performed each year in the United States alone. (1) Gait training is a key aspect of the rehabilitation that follows amputation. A majority [...]
