Rationale: Locked-in syndrome (and its variant, completely locked-in state) generally has a high mortality rate in the acute setting; however, when induced by conditions such as acute inflammatory polyradiculoneuropathy, it may well be curable such that an attempt at cure should be systematically sought by clinicians.
Patient Concerns: A 52-year-old man presented with acute tetraparesia and areflexia, initially diagnosed as Guillain-Barré syndrome. Despite appropriate treatment, his condition deteriorated, evolving into a completely locked-in state.

Objectives: To establish recommendations for designing, delivering, evaluating, and reporting exercise intervention research to improve fitness-related outcomes in people living with spinal cord injury (PwSCI).
Design: International consensus process.
Setting: (1) An expert panel was established consisting of 9 members of the governing panel of the International Spinal Cord Society Physical Activity Special Interest Group and 9 additional scientists who authored or co-authored ≥1 exercise randomized controlled trial paper involving PwSCI.

Objectives: This study analyzes the stimulation parameters implemented during two successful trials that used non-invasive transcutaneous spinal cord stimulation (tSCS) to effectively improve upper extremity function after chronic spinal cord injury (SCI). It proposes a framework to guide stimulation programming decisions for the successful translation of these techniques into the clinic.
Materials And Methods: Programming data from 60 participants who completed the Up-LIFT trial and from 17 participants who subsequently completed the LIFT Home trial were analyzed.

Cervical spinal cord injury (SCI) leads to permanent impairment of arm and hand functions. Here we conducted a prospective, single-arm, multicenter, open-label, non-significant risk trial that evaluated the safety and efficacy of ARC Therapy to improve arm and hand functions in people with chronic SCI. ARC Therapy involves the delivery of externally applied electrical stimulation over the cervical spinal cord during structured rehabilitation.

Mutations in the SLC1A4 transporter lead to neurodevelopmental impairments, spastic tetraplegia, thin corpus callosum and microcephaly in children. SLC1A4 catalyses obligatory amino acid exchange between neutral amino acids, but the physiopathology of SLC1A4 disease mutations and progressive microcephaly remain unclear. Here, we examined the phenotype and metabolic profile of three Slc1a4 mouse models: a constitutive Slc1a4-knockout mouse; a knock-in mouse with the major human Slc1a4 mutation (Slc1a4-K256E); and a selective knockout of Slc1a4 in brain endothelial cells (Slc1a4tie2-cre).
