In the case study, gait asymmetry changes in different speed of walking with ankle-foot prosthesis were identified for developmental tibial deficiency. Joint kinematic, spatial-temporal, and kinetic gait parameters were collected using 3D motion capture system and 3D treadmill simultaneously. Mean values, SD, and symmetry index were calculated for selected gait parameters and descriptively analysed. Results show gait asymmetry of all of the measured parameters. Kinematic joint angular ranges increase with increasing walking speed. Inverse dynamic results present changes in step length and duration which enhance changes in ground reaction force characteristics. The symmetry index shows gait asymmetry, which increases with faster gait speed. Further research is needed to verify this suspect gait asymmetry increasing tendency and to generalise results to ankle-foot prosthesis population with congenital tibial deficiency or transtibial amputation.
