Table 1.
Participant information and prosthetic components.
Fig 1.
Installation of data logger onto prosthetic socket.
Modified sockets for (a) Participant 1, (b) Participant 2, and (c) Participant 3.
Fig 2.
Overall gauge pressure data during 2-Minute Walk test.
Data is shown across (a) Participant 1, (b) Participant 2, and (c) Participant 3. Thin lines indicate raw data and thick lines indicate measurements smoothed using the rloess function in Matlab.
Fig 3.
Individual gauge pressure stride data during 2-Minute Walk test.
Data is shown with pump inactive (top) and pump active (bottom), across (a) Participant 1, (b) Participant 2, and (c) Participant 3. Blue indicates the first stride and yellow the last, with the legend indicating total stride count.
Fig 4.
Normalized individual stride data during 2-Minute Walk test.
Data is shown for gauge pressure (top) and magnitude of acceleration (bottom), across (a) Participant 1, (b) Participant 2, and (c) Participant 3. Dark lines indicate average measurements, with shaded areas indicating standard deviation.
Table 2.
Average measured results over individual strides during 2-Minute Walk test.
Reported as mean ± standard deviation. Significant differences are highlighted. Abbreviations are as follows: press. (pressure), accel. (acceleration), mag. (magnitude).
Table 3.
Average gauge pressure data across initial and final strides during 2-Minute Walk.
Reported as mean ± standard deviation. Significant differences are highlighted.
Table 4.
Average measured results over individual strides during remaining functional tests.
Reported as mean ± standard deviation. Significant differences are highlighted. Abbreviations are as follows: press. (pressure), accel. (acceleration), mag. (magnitude).
