“…The initiation of walking speed decreased was not a surprise, and was planned and practiced by the subjects. Unexpected gait termination has been the subject of other studies [18][19][20]24,25] but data on unexpected slowing has not been reported in the literature.…”

“…There has also been some interest in how gait is initiated [11][12][13][14][15][16][17] and terminated [18][19][20]. Mann et al [11] is an early example of an attempt to quantify the mechanisms and control strategy used to initiate walking from a standing posture in normal humans.…”

“…In able-bodied persons the leading limb, which is the limb that stands still first, is mainly responsible for the production of the necessary braking ground reaction force (GRF). Compared to normal walking the braking GRF is increased in the final stance phase [6][7][8]. A large burst of soleus muscle activity and reduced activation in the tibialis anterior muscle of the leading limb bring the foot flat to the ground [5,7,9,10].…”

Objective: To study the limitations in function and adjustment strategies of lower limb amputees in gait termination. Design: Observational cohort study. Setting: University Medical Centre. Participants: Unilateral transfemoral and transtibial amputees, and able-bodied control subjects. Main outcome measures: Leading limb preference, temporal variables, lower limb joint angles, ground reaction forces, and centre of pressure shift.Results: Compared to able-bodied subjects, amputees showed a decreased peak braking ground reaction force in the prosthetic limb, no anterior centre of pressure shift during leading with the prosthetic limb and an increased mediolateral centre of pressure shift. Amputees used several adjustment strategies to compensate for the limitations in function; leading limb preference for the non-affected limb, longer production of braking force in the non-affected limb, decreased gait termination velocity and more weight-bearing on the non-affected limb. Conclusion: Limitations in function and adjustment strategies were mainly similar in transfemoral and transtibial amputees. Due to the lack of active ankle function, amputees were not able to increase the braking force and to shift the centre of pressure anteriorly. Leading with the non-affected limb is favourable for adequate deceleration and balance control, but in daily life not always applicable. It is important that amputees are trained in gait termination during rehabilitation and prosthetic design should focus on a more active role of the prosthetic foot and knee. #

“…This process is characterized by increased braking forces of the lead foot and reduced trail foot pushoff during the final steps. The biomechanics of gait termination have also been studied in healthy and pathological subjects [13][14][15]. Notably, termination strategies vary depending on gait velocity and whether termination is planned or unplanned [13].…”
