Summary: The study introduces the first quadrupedal robot capable of morphologically adapting to different environmental conditions in outdoor, unstructured environments. Through embodied AI and an adaptation algorithm, the robot transitions between the most energy-efficient morphologies based on currently sensed terrains, showing significant performance improvements over non-adaptive approaches. This demonstration highlights the potential for a new embodied way of incorporating adaptation into future robotic designs.

Summary: This study explores changes in preparatory activity in the motor cortex accompanying motor learning. It was found that changes in preparatory activity were consistent with learned behavioral modifications and reassociated with updated movements. Additionally, preparatory activity uniformly shifted for all movement directions, including those not altered by learning. These persistent preparatory activity patterns may retain a motor memory of the learned field and support accelerated relearning of the same field.

Summary: This study compares the effectiveness of sonomyography and surface electromyography as input modalities for controlling joint torque in powered assistive devices. The results suggest that sonomyography is more accurate in estimating moments than surface electromyography.

Summary: This study compared the muscle activity and joint movement of selected fore- and hindlimb muscles between baseline and induced forelimb and hindlimb lameness conditions. The results showed that there were asymmetrical changes in muscle activity following induced lameness, and the muscular adaptations primarily involved increased bilateral activity and phasic activation shifts.

Summary: This study investigated whether people with Parkinson's disease (PD) show distinct brain activity during regular walking and obstacle avoidance compared to healthy individuals. The results showed that during regular walking, PD patients had higher alpha/beta ratio in the left sensorimotor cortex. When approaching obstacles, both groups decreased alpha and beta power in the premotor and right sensorimotor cortices, and increased gamma power in the primary visual cortex. Only PD patients decreased alpha power and alpha/beta ratio in the left sensorimotor cortex. These findings suggest that PD affects cortical control of walking and changes electrocortical dynamics during obstacle avoidance.

Summary: Post-feedback frontal midline theta activity correlates with error magnitude during motor adaptation, but does not directly drive implicit motor adaptation. Trial-level differences in frontal midline theta activity are related to error magnitude, implying a saliency signal rather than driving adaptation.

Summary: This study demonstrates that the principle of energy optimality in human locomotion can be applied to complex task-level locomotor behaviors. The selection of locomotor strategies is predicted by the relative energy cost integrated across the complete multi-step task. Vision-based remote sensing alone is sufficient to predict the strategy with the lowest prospective energy cost in advance of obstacle encounter. This research highlights the integrative optimizations necessary for energetically efficient locomotion and proposes a new behavioral level that can be used to explore locomotor control and decision-making.

Summary: This study introduces a unified optimality criterion that predicts human walking paths and speeds in various contexts. By characterizing the metabolic cost of turning and generalizing the cost landscape to different trajectories, considering deviations in velocity direction from body orientation, it was found that humans tend to slow down and never use sharp turns when walking.

Summary: Peak accelerations and rate of acceleration show moderate to excellent relative consistency between different running surfaces, but low absolute agreement. Differences in mean values were found for peak accel and rate accel at the shank between overground running and treadmill running, with no significant difference at the lower back.

Summary: This paper shows that the trabecular bone structure provides insights into ontogenetic variation in locomotor loading conditions, as the product of interactions between increases in body mass and neuromuscular maturation. The age-related changes in trabecular bone volume fraction (BV/TV) are strongly associated with ontogenetic changes in locomotor kinetics, which are in turn associated with brain and body size growth in all species. These findings imply that trabecular structure can be a proxy for the rate of neuromuscular maturation and major life history events in fossil subadults.

Summary: The study found that resting snakes have a CSF pressure profile similar to humans and other mammals, but CSF dynamics change during artificial or natural movement. Lateral undulation influences CSF similarly to manual oscillations, but with lower amplitude; concertina locomotion has no impact on CSF dynamics.

Summary: The study systematically reviewed patient-reported outcome measures (PROMs) of musicians' musculoskeletal symptoms (MSS) and psychosocial factors, finding that scales such as MPIIQM, KMPAI, and PRQM show promise but require further validation. Most PROMs lack sufficient evidence of test-retest reliability and construct validity.

Summary: This study translated the Pain Self-Efficacy Questionnaire (PSEQ) into Canadian French (PSEQ-F) and evaluated its validity, reliability, and responsiveness in a French-Canadian sample of patients with persistent rotator cuff related shoulder pain (RCRSP). The results showed that the PSEQ-F is a reliable, valid, and responsive questionnaire that can be used to assess pain self-efficacy in French-speaking individuals with RCRSP. Further studies should use a self-efficacy-specific Global Rating of Change scale to estimate its responsiveness more thoroughly.

Summary: This review synthesized the evidence on the effects of elastic kinesiology tape (KT) on proprioception in healthy and pathological shoulders. The results showed that KT had mixed effects on active joint position sense (AJPS) in healthy shoulders, improved AJPS and passive joint position sense (PJPS) in pathological shoulders, but had no effect on kinesthesia.

Summary: The aim of this paper is to review methods employed to reduce the contamination of single channel EMG signals. Specifically, we focus on methods which enable a full reconstruction of the EMG signal without loss of information. This includes subtraction methods used in the time domain, denoising methods performed after the signal decomposition and hybrid approaches that combine multiple methods.

Summary: This work presents a system for measuring and analyzing motion using a portable electronic device and a flexible fiber sensor. The system includes a new sensor interface circuit that measures the impedance of the fiber, which is composed of multi-walled carbon nanotubes and polydimethylsiloxane elastomer. The measured data is transmitted to a laptop via Bluetooth, allowing for easy integration into a smart garment. The system was assessed on a robotic arm and through various exercises on 5 participants, showing good measurement performance and accuracy.

Summary: The study aimed to investigate the effects of different types of shoes on the EMG activity of pelvic floor muscles and internal oblique muscles during running, as well as their correlation with participants' morphological characteristics. It found that minimalist shoes significantly decreased the activity of internal oblique muscles, but no significant differences were found for pelvic floor muscles when comparing traditional and minimalist shoes. Age showed a significant correlation with the EMG activity of both muscle groups. The long-term effects of minimalist footwear on EMG activity and its relationship to morphological characteristics need further investigation.

Summary: This review evaluates the effect of gait-specific training on corticospinal excitability in stroke survivors. The results suggest that gait-specific training can drive neuroplastic adaptation among stroke survivors, but further studies with better methodology are needed for conclusive evidence.
