NeuroVoices: Kate Rosenbluth, PhD, on Expanding Noninvasive Treatment for Essential Tremor with Cala kIQ Plus

The FDA recently cleared Cala kIQ Plus, an updated, wrist-worn transcutaneous afferent patterned stimulation (TAPS) system, for the temporary relief of action hand tremor in essential tremor (ET) and postural and kinetic tremor symptoms in Parkinson disease (PD). Developed by Cala Health, the device was authorized through the 510(k) pathway on the basis of substantial equivalence to its predecessor, with improvements centered on software, calibration capabilities, and overall usability rather than new pivotal clinical efficacy data.
