Comparison of gait using a Multiflex foot versus a Quantum foot in knee disarticulation amputees

Abstract

The subjective responses and gait patterns of unilateral knee disarticulation amputees wearing prostheses fitted first with the Multiflex foot and then with the Quantum foot were studied. Nine amputees were included in the trial. A questionnaire asked the amputees about their preference for one of the feet. Gait analysis was performed measuring temporal parameters and goniometry of hips, knees and ankles in the sagittal and frontal planes. There was a slight preference for the Quantum foot. Preference seemed not to be related to physical characteristics of the amputees nor to gait parameters. There were no differences in gait as far as the temporal factors were concerned. The main differences in the range of motion of the joints were in the frontal plane: the eversion-inversion movement of the ankle and the adduction-abduction movement of the hip. During walking at comfortable speed with the Multiflex foot the ankle and hip range of motion averaged 2.1 and 3.1 degrees respectively, less than during walking with the Quantum foot.

When to biomechanically examine a lower-limb amputee

“…The remaining 98 studies (3 hip, 53 above-knee, and 42 below-knee) reported accommodation times, tested their participants only once, and did not test on the same day of the participants receiving a new limb (Figure 2, Tables 6 and 7). 7,8,10,13–19,21–24,26–39,41–50,53,54,57,58,61–77,81,82,85,86,88,91,92,94…”

“…Eighty-three of the 156 studies made no comments regarding accommodation or did not provide a justification of a given accommodation time. 5,6,13–17,21,24–27,33,35–37,40–42,48,52,54,56,60–63,66,75,78,79,83–86,91,92,94–96,101,103,104,107,109,112–115,118,120–125,127–131,133–138,140,…”

“…(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) days) compared to the above-knee populations (42 (14-90) days) and the hip populations (77 (69-129) days).…”

The Conventional Non‐Articulated SACH or a Multiaxial Prosthetic Foot for Hypomobile Transtibial Amputees? A Clinical Comparison on Mobility, Balance, and Quality of Life

“…It is a reliable and useful measure of functional mobility especially for people with impairment [ 19 ], TTAs included [ 20 ]. In studies of prosthetic components SSWS has often been used as a parameter for the quality of performance [ 21 , 22 ] also when different prosthetic feet were compared [ 23 ]. According to other studies [ 24 ] the average SSWS (m/s) for each participant was computed dividing the covered distance by 360 seconds.…”
