Sabarish Hariharan Narayanan, PT, submitted an abstract to the 2026 Combined Sections Meeting titled "Differential Excitability of Spinal Networks By Galvanic Vestibular Stimulation in Soleus H Reflex." The program listing shows the submission but does not include data or results.

The title indicates the work examines how galvanic vestibular stimulation (GVS) — a non‑invasive electrical stimulus applied to the vestibular system — affects spinal network excitability as measured by the soleus H‑reflex. The H‑reflex is an electrically evoked spinal reflex used clinically and in research to probe motoneuron and reflex pathway excitability.

The entry appears in the 2026 CSM program; the meeting page provided the listing but no abstract text or figures. Because the program record includes only the title and author, specific methods, sample size, and findings are not available from the listing alone.

For clinicians and researchers tracking vestibular neuromodulation and spinal motor control, the presentation may offer experimental data on how GVS modulates reflex excitability in a lower‑limb postural muscle. Interested readers should consult the CSM proceedings or contact the author for full results and methods once the presentation or paper is released.
