dc.description.abstract | Background:
Walking energy expenditure, calculated as the percent utilization of the maximal aerobic capacity, is little
investigated in transfemoral amputees.
Objectives:
Compare the energy expenditure of healthy participants (control participants) and transfemoral amputees
walking with their respective preferred walking speeds on the treadmill (T
PWS
) and floor (F
PWS
).
Study design:
Randomized cross-over study.
Methods:
Oxygen uptake (VO
2
) was measured when walking with the F
PWS
and T
PWS
. VO
2max
was measured by an incremental
treadmill test.
Results:
Mean
±
standard deviation VO
2max
of the transfemoral amputees and control participants were 30.6
±
8.7 and
49.0
±
14.4
mL
kg
−1
min
−1
, respectively (
p
<
0.05). T
PWS
for the transfemoral amputees and control participants was
0.89
±
0.2 and 1.33
±
0.3
m
s
−1
, respectively (
p
<
0.01). F
PWS
for the transfemoral amputees and control participants was
1.22
±
0.2 and 1.52
±
0.1
m
s
−1
, respectively (
p
<
0.01).
Walking on floor with the F
PWS
, the energy expenditure of the
transfemoral amputees and control participants was 54% and 31% of VO
2max
, respectively (
p
<
0.01). Walking on the
treadmill with the T
PWS
, the energy expenditure of the transfemoral amputees and control participants was 42% and 29%
of the VO
2max
, respectively (
p
<
0.05).
Conclusion:
Energy expenditure is higher for the transfemoral amputees than the control participants, regardless of
walking surface. There are minimal differences in energy expenditure between treadmill and floor walking for the control
participants but large differences for the transfemoral amputees.
Clinical relevance
During walking, the transfemoral amputees expend a larger percentage of their maximal aerobic capacity than healthy
participants. With a low VO
2max
, ordinary activities, such as walking, become physically more challenging for the
transfemoral amputees than the control participants, and this may, in turn, have a negative effect on the walking range
of the transfemoral amputees. | en_US |
