Model and measurement studies on stages of prosthetic gait.


General conclusion

The outcomes and insights gained from these studies can be used to predict how TF amputees can compensate for the absence of active control of the prosthetic limb. This absence of active control has consequences for the positioning of the CoP during gait initiation and termination, the active knee extension control during weight bearing on the prosthetic limb and the prosthetic limb swing during the swing phase. The observed real world phenomena and predictions of our models of the conceptual world show that the sound limb dependency is an important strategy during gait initiation and termination, which contributes to patients’ functional ability. Also, these findings can be used to predict which strategies contribute to successful prosthetic limb forward swing during obstacle avoidance and what should be taken into account during obstacle avoidance. These models can be of interest when forming new ideas on how to improve prosthetic knees and feet and how to improve rehabilitation programs. The findings were used to increase our insights and contributed to the development of our theory on TF prosthetic gait. Based on the findings in the laboratory, which show that compensation strategies mainly depend on the dexterity of the sound limb, it seems that it is an unattainable goal to pursue symmetry during prosthetic gait.
