Summary: The objective of this meta-analysis was to evaluate the effect of whole-body vibration training on lower limb motor function in children with cerebral palsy. Thirteen randomized-controlled trials were included in the analysis, and the results showed that whole-body vibration training could effectively improve the lower limb motor function of children with cerebral palsy.

Summary: The relationship between focal muscle spasticity and kinematics of walking in traumatic brain injury patients was examined. It was found that focal muscle spasticity had little relationship with kinematic variables and walking speed in this cohort of people with TBI who could walk without assistance.

Summary: This study aimed to investigate the relationship between muscle spasticity and gait kinetics in individuals with Traumatic Brain Injury. The findings showed that individuals with Traumatic Brain Injury had altered gait kinetics compared to healthy controls, but the impact of focal muscle spasticity on gait kinetics was minimal.

Summary: This paper presents an EMG-based gait pattern adaptation method that allows subjects to control a robotic exoskeleton for gait rehabilitation. The results show that the subjects were able to change the gait pattern of the exoskeleton using EMG signals and achieved the adaptation goals within a short period of time. This method enables subjects to actively participate in the rehabilitation training.

Summary: Spastic equinus foot is a common deformity in neurologic patients related to muscle imbalance. Surgical management requires the identification of relevant components using various methods, including examination, motor nerve blocks, and instrumented 3D gait analysis. This retrospective cohort analysis of 40 adults shows the importance of tibial motor nerve block in removing spastic calf dystonia and assessing calf contracture.

Summary: This study investigated biomechanical differences in walking between adolescents with ASD and neurotypical controls at matched speeds. It found that while adolescents with ASD walk with a similar pattern in the propulsive plane as controls, they exhibit alterations in the supportive plane.

Summary: This study aimed to assess the odds and time of lower extremity musculoskeletal injury (LEMSKI) after concussion in US collegiate athletes. The results showed that there was no significant increase in the odds of LEMSKI after concussion, but higher odds of non-time loss (NTL) LEMSKI and lower odds of time loss (TL) LEMSKI were observed in football.

Summary: Aerobic exercise has positive effects on mitochondrial activity and muscle mass in older adults, but its impact on patients with peripheral artery disease remains unclear. Studies show that walking exercise may increase lower extremity ischemia in PAD patients, and more research is needed to clarify the underlying mechanisms.

Summary: This study investigated the effects of gait speed on the cooperative modules and functional connectivity between muscles. By analyzing surface electromyography (sEMG) signals, the researchers found that gait speed influences the strength of connections and coordination patterns among muscles, and is related to the regulation of the neuromuscular system.

Summary: This study explores the correlations between spasticity and motor impairments in upper and lower limbs of ambulatory chronic stroke survivors. The results show that there is a significant correlation between spasticity and motor impairments in the upper limb, but not in the lower limb. Grip strength is significantly correlated with motor impairment in the upper limb, while gait speed is significantly correlated with motor impairment in the lower limb.

Summary: This study determined the optimal cut-off score for the Modified Ashworth Scale (MAS) in predicting unfavorable outcomes for mobility and walking ability in stroke patients. Moderate level of plantar flexor muscle spasticity was found to have the highest sensitivity and specificity in predicting poor gait speed and good mobility performance.

Summary: Transcranial magnetic stimulation (TMS) is commonly used to study motor control and neurorehabilitation of upper extremities, but its use in lower extremity postural and walking-specific motor control is limited. This study presents a methodological report on enabling TMS assessments post-stroke in a standing posture, which allows for a more reflective state of the neuromuscular system during postural and walking tasks. Assessments in standing position increased the TMS response rate and allowed for lower stimulation intensities, providing a common approach for assessing lower extremity corticomotor response post-stroke.

Summary: The pilot study showed that interval functional electrical stimulation (FES) cycling combined with nutritional counseling can effectively reduce body fat percentage and increase lean muscle mass in obese adults with chronic SCI. Further research with larger sample sizes and potential additional strengthening programs before FES cycling initiation may be warranted to optimize obesity treatment.

Summary: This study aimed to investigate the interactive effects of proximal arm impairment and passive weight compensation on shoulder flexion performance after stroke. The results showed that shoulder flexion performance depends on proximal arm impairment and is influenced by the degree of unloading/loading provided, particularly among individuals with moderate paresis after stroke.

Summary: The study found that knee extensors and flexors in stroke patients were weaker compared to healthy controls, with higher relative power in the spectral analysis of agonist EMG signals in the paretic leg. In terms of antagonist coactivation, the paretic leg showed significantly higher coactivation levels compared to the non-paretic leg, with higher levels of coactivation associated with weaker knee flexors.

Summary: The study found that in individuals with SCI, most believe that control over health outcomes lies in the hands of doctors; there are limited changes in health LOC beliefs and predictors within the first year post-SCI; education level, race, and SCI level can significantly influence a patient's health LOC beliefs.

Summary: This study found that gait characteristics improved in stroke patients during the subacute phase and at 6 months post-onset, but stabilized thereafter. An increase in gait speed was associated with initial slower walking, shorter stride length, and more pronounced asymmetry. The improvements in lower-extremity motor function and bilateral step parameters suggest a combination of neurological recovery, compensatory strategies, and physical therapy influencing gait changes in the first 6 months post-stroke.

Summary: Inconsistent results in temporospatial gait variability after stroke were found. It was observed that gait variability was higher in slower speeds both in stroke subjects and healthy controls, but after controlling for gait speed, only a few temporal parameters showed increased variability related to stroke.

Summary: Neuromodulation via spinal stimulation has been studied for its effects on motor function and spasticity reduction in individuals with spinal cord injury. This study investigated the impact of continuous lumbosacral transcutaneous spinal stimulation at different frequencies on robotic torques and EMG patterns during stepping. The results revealed frequency-dependent changes in motor profiles among individuals with chronic motor incomplete SCI.

Summary: The study aimed to determine the useful parameters of the pendulum test for detecting hypertonia in the knee muscles and evaluating the individual and group responses to intrathecal baclofen injection. The results showed that the pendulum test parameters can effectively detect hypertonia in the knee muscles, with some parameters better at detecting hypertonia (SwingT, E1V) while others more responsive to post-injection muscle tone normalization (E1V, relaxation index).
