Treadmill training program for a bilateral below-knee amputee patient with cardiopulmonary disease.
This study was undertaken to determine the degree of progress an elderly bilateral below-knee amputee with cardiopulmonary disease could achieve by endurance training on a treadmill. Aspects of medications, orthotic/prosthetic evaluation, and energy expenditure are discussed. The subject was a 63-year-old Class IV cardiac patient with combined restrictive-obstructive pulmonary disease of moderate severity. He had undergone a coronary artery bypass graft (two-vessel) followed by a bilateral below-knee amputation for an ascending dry gangrene. The initial ambulatory aerobic evaluation showed the patient achieving only 50% of predicted maximal heart rate and 20% of maximal oxygen consumption. An individualized daily training program started the patient walking at .5 mph, 0% elevation, for five repetitions at two minutes each. By the end of the six-month training program the workload reached 1.4 mph at 2.5% elevation, for 30 minutes of total external work. The final exercise test evaluation showed an overall increase in age-predicted maximal heart rate (90%) and oxygen consumption (55%). The patient improved from cardiac Class IV to Class II, and therapeutically from Class E (bed rest) to Class C (moderate exercise restriction). These findings suggest a need for endurance training programs for patients with cardiopulmonary disease hindered by additional physical disabilities. The program enabled the participant to engage in significantly higher levels of activity for daily living within the community.
