Tensor electrical impedance myography identifies bulbar disease progression in amyotrophic lateral sclerosis

•Tensor electrical impedance myography reduces complex multi-frequency, multi-electrode configuration impedance data down to a single metric.•This metric captures disease progression more sensitively than other bulbar disease biomarkers, including tongue strength and the ALS-FRS-R.•Tensorelectrical...
