Exoskeleton gait training on real-world terrain improves spatiotemporal performance in cerebral palsy.

Introduction: Walking is essential for daily life but poses a significant challenge for many individuals with neurological conditions like cerebral palsy (CP), which is the leading cause of childhood walking disability. Although lower-limb exoskeletons show promise in improving walking ability in laboratory and controlled overground settings, it remains unknown whether these benefits translate to real-world environments, where they could have the greatest impact.
Methods: This feasibility study evaluated whether an untethered ankle exoskeleton with an adaptable controller can improve spatiotemporal outcomes in eight individuals with CP after low-frequency exoskeleton-assisted gait training on real-world terrain.
Peripheral nerve injury induces dystonia-like movements and dysregulation in the energy metabolism: A multi-omics descriptive study in Thap1 mice.

DYT-THAP1 dystonia is a monogenetic form of dystonia, a movement disorder characterized by the involuntary co-contraction of agonistic and antagonistic muscles. The disease is caused by mutations in the THAP1 gene, although the precise mechanisms by which these mutations contribute to the pathophysiology of dystonia remain unclear. The incomplete penetrance of DYT-THAP1 dystonia, estimated at 40 to 60 %, suggests that an environmental trigger may be required for the manifestation of the disease in genetically predisposed individuals.

Ankle-foot orthoses (AFOs) have been commonly prescribed for stroke survivors with foot drop, but their impact on the contractions of paretic tibialis anterior (TA) and medial gastrocnemius (MG) has remained inconclusive. This study thus investigated the effect of AFOs on these muscle contractions in stroke survivors. The contractions of paretic TA and MG muscles were assessed in twenty stroke patients and compared between walking with and without AFOs, using a novel wearable dynamic ultrasound imaging and sensing system.

Article Synopsis
- Clinical rating scales often miss the full range of dystonic symptoms, prompting the need for a reliable biomarker to assess the effectiveness of deep brain stimulation (GPi-DBS) for treating dystonia.
- In a study of 12 patients undergoing GPi-DBS, researchers found that those with arm dystonia had higher intermuscular coherence in the 4-12 Hz range before surgery, which significantly decreased after the procedure.
- Despite the observed changes in coherence, the study found no strong links between coherence levels and clinical rating scale scores, suggesting that more research is needed to determine the biomarker's clinical utility.
Comparisons of functional movements and core muscle activity in women according to Pilates proficiency.

Sports Science Research Center, College of Physical Education, Kyung Hee University, Yongin, Republic of Korea.
Introduction: This study aims to investigate the differences in functional movements and core muscle activities between experienced and novice practitioners during Pilates exercises.
Methods: Thirty-eight participants were recruited for the study, comprising 19 experienced and 19 novice Pilates practitioners. Participants performed functional movement screening (FMS) tests and six Pilates exercises at the basic, intermediate, and advanced levels.
