This study comprised of 22 unilateral trans-tibial amputated patients who were seen at the authors' Prosthetics and Orthotics Laboratory for the purpose of prosthetic provision. Measurements were made using plurimeter and caliper and gait observations were made by video camera. In the sagittal and horizontal planes respectively the pelvic tilt was measured to be 12d` and 5.73d`, and such measurements in relation to the trunk extensor and flexor muscles were shown to be statistically significant (p<0.05). On the contrary, the same could not be said for frontal plane measurements. In addition, in 9 cases excessive knee flexion was noted during the stance phase having a direct influence on the pelvic tilt (p<0.05). © International Society for Prosthetics and Orthotics 1998.
