Abstract

Background & Purpose: Gait asymmetry represents one of the primary issues for individuals with unilateral amputations of the lower limbs in order to prevent excessive stress on the sound leg.

Aim of the work: To analyze of pressure distribution through the foot of the sound limb to evaluate the mechanical risk factors in unilateral amputees.

Patients and Methods: We included 30 subjects classified into 15 traumatic unilateral trans-femoral or trans-tibial amputees without advanced osteoarthritic changes or foot deformities were collected and 15 normal individuals as a control group. All patients have undergone careful history-taking, including a sound limb investigation for skin integrity and sensation, muscle power, and joint range of motion, along with pressure distribution with my Walkway Tekscan device.

Results: A comparison study between the two groups in the examined population demonstrated a significantly significant decrease in S-A surface area in the amputated limb in the case group in comparison with the control group (p 0.001). Moreover, we discovered a highly significant decrease in SA force in the amputated leg in the case group in comparison with the control group (p 0.001). Furthermore, comparative research between the two groups demonstrated a very significant increase in SA area% change and S-A force% change in the case group in comparison with the control group (p 0.001).

Conclusion: To conclude, our study found that when comparing cases to controls, both sound limb to amputation area and force % changes were considerably larger in cases, indicating overloading on the sound limb when walking.
