PURPOSE

The TRG, founded in 2001 is organized as an independent, nonprofit organization of scientific investigators who conduct research at the institutions with which they are affiliated. The TRG aims to advance knowledge about the cause, pathogenesis and clinical impact of tremor disorders and to develop and implement scientific strategies to examine promising therapeutic interventions. The views of the TRG do not necessarily represent the views of the institutions with which the investigators are affiliated.

WHO ARE WE?

The Tremor Research Group (TRG) representing a consortium of scientific investigators from centers who are committed to cooperative planning, implementation, analysis and reporting of controlled clinical trials and of other research for tremor disorders. Membership is by invitation only and includes researchers who have distinguished themselves in the field of tremor.

ORGANIZATION

The TRG is governed primarily by a three member Executive Committee consisting of a President, Vice President, and Secretary/Treasurer who are elected by the voting members.The Executive Committee members hold terms of three years and may be elected to succeed themselves for up to two consecutive terms. New members are nominated by current membership and approved by 2/3 of entire membership.

PROJECTS

The TRG has developed, validated, and published a comprehensive rating scale for essential tremor (TETRAS). Education and credentialing for the scale is available.  The TRG is serving was the core rating site for the focused ultrasound for essential tremor study (ET002), sponsored by InSightec. The TRG and TRG sites have worked with multiple pharmaceutical companies including Sage, Biohaven, CAVION and CADENT to develop and implement clinical trials for essential tremor.
