Exercise testing as a screening measure for ability to walk with aprosthesis after transfemoral amputation due to peripheral vascular disease
Abstract Purpose : To establish at which exercise-power level is the vascular response , as measured by oxygen uptake , closest to the response during the 6-min walk test ( 6 MWT ) in people after lower-limb amputation due to peripheral vascular disease ( PVD ) . Method : A prospect i ve exploratory cohort study was conducted . 6 MWT and exercise testing using a h and -wheel ergometer ( starting at 10 W and increasing the workload by 10 W ) were performed in 101 consecutively recruited participants after transfemoral amputation due to PVD . Agreement of oxygen uptake during 6 MWT and exercise testing was compared between the groups defined by the exercise-power level reached . Results : Linear regression through origin with Chow test for comparing slopes indicated that oxygen uptake at 30 W agreed more with 6 MWT than at 20 , 40 or 50 W. Analyses of observed differences ( one-way ANOVA with post-hoc tests , Jonckheere – Terpstra test ) confirmed 30 W to be the recommendable threshold . Conclusions : At the level of 30 W , the oxygen uptake during the exercise was the closest to the 6 MWT , so we estimated that to be the minimum required level for walking using a prosthesis after transfemoral amputation due to PVD . Implication s for Rehabilitation Exercise testing after transfemoral amputation . Walking with a prosthesis causes notable strain to the person ’s vascular system : after the 6-min walk test , the participants ' heart rate reached 75 % of the maximum predicted heart rate on average . The study shows that persons after transfemoral amputation due to peripheral vascular disease who reach the level of 30 W or more in exercise testing with an arm ergometer at admission to rehabilitation are likely to be able to walk in-doors using a prosthesis
