Persons post-stroke improve step length symmetry by walking asymmetrically.

Background And Purpose: Restoration of step length symmetry is a common rehabilitation goal after stroke. Persons post-stroke often retain the ability to walk with symmetric step lengths ("symmetric steps"); however, the resulting walking pattern remains effortful. Two key questions with direct implications for rehabilitation have emerged: 1) how do persons post-stroke generate symmetric steps, and 2) why do symmetric steps remain so effortful? Here, we aimed to understand how persons post-stroke generate symmetric steps and explored how the resulting gait pattern may relate to the metabolic cost of transport.

Autoimmune glial fibrillary acidic protein astrocytopathy resulting in treatment-refractory flaccid paralysis.

Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is an autoimmune neurological disorder associated with the presence of anti-GFAP IgG. Meningoencephalitis is the predominant clinical presentation of autoimmune GFAP astrocytopathy in published case series. We report a case of autoimmune GFAP astrocytopathy with the unusual feature of radiculoneuritis in addition to encephalomyelitis, resulting in flaccid paralysis unresponsive to immunotherapy.
