“…However, the 17 patients in the OI group represented more than 10 percent of the existing population of patients treated with TFA OI prostheses worldwide at the time of the study [9][10]. Moreover, the number of participants is comparable to other studies in the prosthetic and orthotic field [35,[39][40][42][43]. Because of practical considerations, the test was performed in a sitting position.…”

Abstract-This study investigated detection thresholds of vibrometric stimuli in patients with transfemoral amputation supplied with osseointegrated (OI) and socket-suspended prostheses. It included 17 patients tested preoperatively with socket-suspended prostheses and after 2 yr with OI prostheses and a control group (n = 17) using socket-suspended prostheses, evaluated once. Assessments on the prosthetic and intact feet were conducted at six frequencies (8,16,32, 64, 125, and 250 Hz). Furthermore, measurements were conducted to investigate how vibrometric signals are transmitted through a test prosthesis. The results showed that the OI group had improved ability to detect vibrations through the prosthesis at 125 Hz (p = 0.01) at follow-up compared with the preoperative measurement. Compared with the control group, the OI group at follow-up had better ability to detect high frequency vibrations through the prosthesis (125 Hz, p = 0.02; 250 Hz, p = 0.03). The vibrometric signal transmitted through the test prosthesis was reduced at 8, 125, and 250 Hz but was amplified at 16, 32, and 64 Hz. Differences between the OI and the control groups were found in the highest frequencies in which the test prosthesis showed reduction of the vibrometric signal. The study provides insight into the mechanisms of vibration transmission between the exterior and bone-anchored as well as socketsuspended amputation prostheses.

“…Thus, transfemoral amputees are forced to modify their gait pattern and adopt gait deviations like circumduction, hip-hiking and vaulting to be able to move forwards. 7 These gait deviations have been shown to be very energyconsuming. 8 This is also supported by the subjects' ratings of perceived exertion and the heart rate data.…”

“…The gait deviations often observed in this specific gait situation are circumduction, hip-hiking and vaulting due to the prosthetic leg becoming functionally too long. 7,8 Inability to adapt to tilted surfaces can be a result of several factors, e.g., reduction in hip flexion due to a weakened muscle apparatus after the amputation or restrictions from the prosthetic socket, lack of optimal knee flexion and timing in the prosthetic knee joint, and total loss of active ankle dorsiflexion in the prosthetic foot. 8 Walking on rising and tilting terrain outdoors is often mentioned by the transfemoral amputee as particularly strenuous.…”

Transfemoral amputees often report that walking on tilted pavements or on terrain with the prosthesis on the side of higher elevation is quite strenuous. This study investigates the energy expenditure of transfemoral amputees (n ¼ 8) on a motorized treadmill, simulating different strenuous outdoor walking conditions. Oxygen uptake at self-selected speed of gait was measured during walking at three different treadmill positions: (i) Horizontal treadmill, (ii) 3% tilt in the sagittal plane and (iii) 3% tilt in both the sagittal and frontal plane of the treadmill. The difference in median values of oxygen uptake between position (i) and (ii) was 4.3%, and 16.4% between position (ii) and (iii) (p 0.05, for both comparisons). The subjects utilized about 50% of their VO 2max when walking in position (i) and (ii), with an increase to about 60% of their VO 2max when walking in position (iii). Transfemoral amputees use significantly more energy when walking on a moderately tilted surface in the frontal plane compared to walking with a tilt in the sagittal plane. This is probably because the prosthetic leg becomes functionally too long when the walking surface is tilted sideways, and the transfemoral amputees adopt a more energy consuming gait pattern.

Spinal, pelvic, and hip movement asymmetries in people with lower-limb amputation: Systematic review

et al. 2015

View full text Add to dashboard Cite

Abstract-Following amputation, people with transfemoral amputation (TFA) and transtibial amputation (TTA) adapt with asymmetrical movements in the spinal and lower-limb joints. The aim of this review is to describe the trunk, lumbopelvic, and hip joint movement asymmetries of the amputated limb of people with TFA and TTA during functional tasks as compared with the intact leg and/or referent leg of nondisabled controls. Electronic databases were searched from inception to February 2014. Studies with kinematic data comparing (1) amputated and intact leg and (2) amputated and referent leg of nondisabled controls were included (26 articles). Considerable heterogeneity in the studies precluded data pooling. During stance phase of walking in participants with TFA, there is moderate evidence for increased trunk lateral flexion toward the amputated limb as compared with the intact leg and increased anterior pelvic tilt as compared with nondisabled controls. None of the studies investigated spinal kinematics during other functional tasks such as running, ramp walking, stair climbing, or obstacle crossing in participants with TFA or TTA. Overall, persons with TFA adapt with trunk and pelvic movement asymmetries at the amputated limb to facilitate weight transfer during walking. Among participants with TTA, there is limited evidence of spinal and pelvic asymmetries during walking.
