Summary: The study investigated how Swinhoe's striped squirrels adjust their locomotion on different supports, finding that they predominantly use asymmetrical gaits with a preference for full bounds. The squirrels made adjustments on inclined surfaces to increase stability and optimize the loading distribution between fore- and hind limbs. These findings suggest a preference for asymmetrical gaits in early members of the Euarchontoglires, shedding light on the ancestral lifestyle of this mammalian 'superclade'.

Summary: The paper introduces a new method for evaluating the stability of cosmonaut locomotor functions after long-duration spaceflight based on ground-reaction forces analysis. Various probabilistic indicators were introduced and showed promising potential in determining locomotor function states. Further trials of this method may provide valuable insights into human movement alterations after spaceflight.

Summary: This study investigated external mechanical work at different running speeds for unilateral transfemoral amputees wearing running-specific prostheses. The net external work in the affected limb tended to be greater than that in the unaffected limb, and was positive for the affected limb while negative for the unaffected limb.

Summary: This paper aims to define an experimental protocol and methodology to estimate lower limb internal joint reaction forces in high-fidelity hypogravity conditions. By collecting state-of-the-art kinetics, kinematics, muscle activation and muscle-tendon behavior data, a musculoskeletal modeling framework will be used to estimate joint loading. The results of this study will provide first estimations of internal musculoskeletal loads associated with human movement performed in a range of hypogravity levels.

Summary: This study aimed to identify the best measures to distinguish between individuals with Parkinson's disease and healthy individuals based on dual-task gait and turning costs. The findings suggest that people with Parkinson's disease rely more on executive-attentional resources to control arm swing, foot strike, and turning, but not gait speed. Arm range of motion was found to be the most discriminative measure of dual-task costs between Parkinson's disease patients and healthy individuals.

Summary: This study developed a new metatarsophalangeal (MTP) assistive device and investigated its effectiveness on the muscle activities of the lower extremities during walking. The results showed that the MTP flexor muscle activity was significantly reduced with the assistive device, without interfering with the action of other muscles or the MTP joint angle.

Summary: The study found that walking speed did not affect propulsion in healthy adults, with slower walking balancing the lower AP-GRFs through longer time integration. Other methods found that propulsion increased with walking speed, and results varied depending on the analysis method used in the gait pathology dataset.

Summary: This study investigated the effect of different weights of backpack carriage on the gait of schoolchildren. The results showed that carrying a load of 12% and 15% of body weight altered the gait performance of schoolchildren, and these altered variables should be considered as a risk factor for carrying a backpack.

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: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
