Summary: A study found intriguing adaptations in sprint running gait during fatigue. Contrary to expectations, the differences between legs were greater in non-fatigued sprinting. Additionally, during fatigue, the non-dominant leg shifted towards greater horizontal force production, accompanied by increased work at the distal joint.

Summary: Initial acceleration is crucial for success in sprinting, but running-induced fatigue can impair acceleration. However, little is known about the effects of fatigue on acceleration and the associated running technique. In this study, well-trained running athletes were able to maintain acceleration despite changes in running technique, possibly by compensating with increased knee joint function due to greater fatigue in the hip extensor muscles.

Summary: Adding mass affects human movement and alters lower limb muscle activities. This study investigated the influence of added mass on lower limbs by analyzing kinematics, muscle activities, and energy consumption. The results showed that with increased mass, muscle activation and joint torque increased, stride time decreased, and energy expenditure raised correspondingly. Overall, participants adjusted their muscle activities and movement patterns in response to added mass, indicating a relationship between energy consumption and added mass.

Summary: The study investigates the impact of adding mass to lower-limb exoskeletons on joint kinematics and kinetics during walking. Results show that smaller masses have limited effects, while larger masses significantly alter joint movements and forces. These findings can inform the design and control strategies of future exoskeletons.

The results showed that the system provided reliable measurements for most parameters in walking analysis, but different reliability values were observed in running analysis. Although the system may be useful for gait analysis, further validation against a gold standard system is needed.

Summary: The study aimed to determine the reliability of lower limb kinematic and electromyographic variables during gait in toddlers with typical development and unilateral cerebral palsy. Results showed high intersession and intertrial reliability, but significant variability among subjects, sessions, and trials. In toddlers with unilateral cerebral palsy, EMG variables of affected side and distal muscles were found to be most reliable.

Summary: Adults with spinal deformity (ASD) have altered sitting and standing kinematics, depending on the type of deformity. ASD-sag patients show decreased mobility in certain joints, while ASD-hyperTK patients show increased mobility and deformity severity in certain spinal segments. Surgical correction may improve quality of life for ASD patients.

Summary: This study used a subject-specific 3D approach to assess dynamic postural alignment in individuals with Autism Spectrum Disorder (ASD) during walking. The results showed that ASD patients with dynamic postural malalignment had altered kinematics in the trunk, pelvis, and lower limbs, making them more prone to falls. The study also found that dynamic ODHA was better correlated with health-related quality of life outcomes than dSVA and dPT.

Summary: This study investigated the muscular and neurological disorders in children with unilateral cerebral palsy and the role of the peroneus longus (PL) in equinovalgus gait. The results suggest a gradual deterioration of muscular disorder and a link between muscular and neurological disorders, with the PL being more activated than the gastrocnemius medialis (GM) and may be considered an intervention target for treating equinovalgus gait.

Summary: This study aimed to investigate the impact of using wand-mounted or skin-mounted markers on the lateral thigh and shank segments in the conventional gait model. The analysis of gait data from 147 subjects with wand-mounted markers and 73 subjects with skin-mounted markers revealed that skin-mounted markers were more prone to colinearity and had a greater effect on joint angle calculation, as well as a larger potential effect from marker misplacement and soft tissue artefact.

Summary: This study aimed to evaluate the effects of abobotulinum toxin A injection to the peroneus longus muscle in children with unilateral spastic cerebral palsy and equinovalgus gait. The results showed significant improvement in foot radiology measures, increased active dorsiflexion, improved walking speed, and gait score. Electromyography results indicated decreased activation for the peroneus longus muscle during reference exercises. The study suggests that treating the peroneus longus muscle alone can address foot deformities without interfering with the main plantar flexors.

Summary: This study assessed the value of referral strategies for axSpA in patients with suspicious chronic inflammatory LBP and identified predictive factors for the final diagnosis of axSpA in Middle Eastern Arab countries. The optimal referral strategy was found to be MASTER, which includes IBP, good response to NSAIDs, positive HLA-B27, and SpA family history. Predictive factors for axSpA include MRI sacroiliitis, positive HLA-B27, high CRP, psoriasis, IBP, and longer symptom duration.

Summary: This study aimed to investigate the relationship between pelvic retroversion and increased hip loading in adults with spinal deformity. The findings showed that patients with pelvic retroversion exhibited more severe postural malalignment in both static and dynamic conditions, along with increased acetabular anteversion, external coverage, and decreased anterior coverage during gait. These changes in acetabular orientation were found to be associated with hip osteoarthritis.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Summary: The study found that the reliability of stiffness, viscosity, and inertia of the ankle joint was good to excellent during standing. During walking, the reliability of stiffness and viscosity was also good to excellent, while that of inertia was fair to good.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
