Summary: Robotic-assisted therapy (RAT) did not significantly change spatiotemporal parameters and kinematics of walking in children with spastic cerebral palsy, except for limited improvement in some aspects of gait symmetry. There were no differences in changes in selected objective gait parameters among children with CP at different ambulatory levels.

Summary: This study used the k-nearest neighbor algorithm to assess fall risk by combining gait stability and symmetry analysis of acceleration signals. The results showed that the kNN classification on gait stability and symmetry had good accuracy in distinguishing non-fallers and recurrent fallers.

Summary: Symmetry is an important factor in analyzing gaits, and backward gait has been an area of interest for its physiological and therapeutic possibilities. This study aimed to compare the symmetry of pressure parameters between backward and forward gaits using different indices. 81 healthy participants aged between 19 and 84 years were included in the study. Foot pressure distribution was analyzed during self-selected speeds of backward and forward gaits. Higher degrees of asymmetry were found during backward gait, particularly in toes II-V, forefoot, metatarsals I, II, and III, medial and lateral heel areas. There was no significant correlation between symmetry indices and age or BMI. The results suggest that the lower symmetry of backward gait is due to the increased number of corrective movements required for maintaining body balance and overall symmetry. This may be achieved through increased cortical control, as backward gait was a novel movement task for all participants.

Summary: Humans regularly walk in curvilinear trajectories but the choice of locally-defined reference frame during turning gait affects the analysis of spatiotemporal and biomechanical measurements. This study investigated how different reference frame definitions impact gait measures and interpretations during turning. Results showed significant differences in step length, step width, and margins of stability based on the choice of reference frame. The conclusions about asymmetry in turning gait were also altered depending on the reference frame. This highlights the importance of justifying and specifying the reference frame in studies of turning gait.

Summary: Gait stability is impaired in polio survivors with plantarflexor weakness, characterized by increased step width and step length variability and lower MoSAP. These factors are related to the elevated energy cost of walking in polio survivors.

Summary: A novel gait stability index was established based on kinematic information, highly correlated with a popular kinetic stability index, suggesting potential value in both clinical and commercial applications. The combination of three principal motions showed moderate correlation with MoS values in a specific direction, indicating the potential of the new kinematic index as an alternative to MoS.

Summary: This study proposes a measure called the all-round margin of stability (MoS) to evaluate the kinematic balance in all directions. By analyzing the characteristics of the all-round MoS through a curving experiment, it was found that the parameters such as velocity and step width matched the features of the all-round MoS. This research is significant for the evaluation and improvement of gait assist devices.

Summary: This exploratory study aimed to examine dynamic balance control in individuals with mild to moderate Parkinson's disease (PD) and healthy individuals while walking and performing 90 degrees turns. The results showed no significant differences in spatiotemporal parameters or dynamic balance variables between the groups. Gait velocity, center of mass-center of pressure (COM-COP) inclination angle at midstance, and marginally significant group differences in margin of stability (MOS) variables were observed. It suggests that dynamic balance during gait while performing turns may not be significantly affected in the early stage of Parkinson's disease.

Summary: This study examined the relationship between trunk motion and narrow-based gait in healthy adults. The results showed that reducing trunk motion significantly decreased step width and mediolateral center of mass excursion, without altering the mediolateral margin of stability. These findings suggest a strong coupling between center of mass motion state and mediolateral margin of stability.

Summary: Introducing unexpected perturbations to challenge gait stability is an effective approach to investigate balance control strategies. This study aimed to determine how subjects adapted gait stability to small perturbations applied stride-by-stride. The findings show that even small perturbations disrupt gait stability, and subjects can adapt their reactive balance control through feedback and feedforward strategies.

Summary: Kinetic gait data is used to evaluate a dog's orthopedic soundness and treatment response. Traditionally, gait data was collected from the most affected limb, but symmetry indices are now used to evaluate forces between paired limbs. Standing gait analysis is suggested for non-weight bearing lame or highly impaired dogs.

Summary: In human gait, passive dynamics are used to achieve energy-efficient walking, except when crossing an obstacle where caution is taken to maintain stability. Humans proactively manipulate the passive dynamics while approaching the obstacle to meet the demands of the locomotor task. Step length and center of mass motion co-vary to maintain specific levels of passive dynamic stability for each step.
