Muchas personas recorren consultorios sin una respuesta clara, y distinguir entre un origen funcional y uno orgánico evita tratamientos innecesarios. Es una señal de que hay que mirar bien antes de asumir una enfermedad grave. Aun así, al tratarse de una serie retrospectiva de dos centros, los resultados no alcanzan para generalizar.","quienFirma":"Centros clínicos de dos instituciones (estudio retrospectivo)","confianza":"preprint","consulta":null},"sello":{"hash":"7b2c9cce4556cba68cf35555eedb6e46baaf5d9b97b185ddeef75e00423cd5f3","sello":"8c0d0e546fd30d826ef6178a5f5c152208e34f47b5c8cdbdc75851039e18d0b7","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569549,"aleatorio":"40f90a7c24002ff2f2230484261fe0762689a5f23536372bd9ca78a1043380ae","tiempo":"2026-10-20T17:31:30.000Z"},"nist":{"cadena":2,"pulso":1991980,"salida":"69E07DFEE11EFF4D62E2205CD9F3F399D52FEF236584C85A7AE96BEA74AB3905C910288488E7107D6A6068B76293A18CD91AD3E13518452A6064E4922DB00D59","tiempo":"2026-10-20T17:31:00.000Z"},"noAntes":"2026-10-20T17:31:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 17:31:39 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Functional and Organic Pseudo-Orthostatic Tremor: Clinical Features, Electrophysiology, and Treatment Outcomes in a Retrospective Cohort","descripcion":"Background: Pseudo-orthostatic tremor (psOT) is a rare form of tremor of the lower body, triggered by standing, at frequencies lower than 13 Hz. It is believed to be secondary to other neurological disorders in a large proportion of cases. Surface electromyography (sEMG) can identify its core characteristics and differentiate it from other similar disorders such as primary orthostatic tremor (POT) and orthostatic myoclonus (OM). Objectives: Our study aims to illustrate the clinical and neurophysiological features as well as the outcomes and final diagnoses of patients with psOT in a retrospective two-centre cohort. Methods: We retrospectively examined the available clinical and neurophysiolo","pubDate":"2026-10-20","url":"https://www.medrxiv.org/content/10.64898/2026.10.18.26365840v1?rss=1"},"indexado":"2026-10-20T17:30:28.766Z"}}
