Metric anchors for TETRAS performance measures of head and extremity tremor In a preliminary study, 10 members of TRG simultaneously rated 10 ET patients during the live administration of the TETRAS performance subscale. Excellent inter-rater reliabilities were found for head and upper limb tremor. In another preliminary study, ten members of TRG simultaneously rated three patients with mild, moderate and severe ET and rated the videos of these exams one month later. The correlations between video scores and live exam scores were greater than 0.87 for all items except face (0.67) and voice (0.63) tremor. We now estimate the inter- and intra-rater reliabilities of the TETRAS performance subscale and the correlation of this subscale with the ADL subscale, using 50 videotaped exams. Methods All studies were performed with the signed written informed consent of the patients and controls, approved by the institutional review board of each institution. Patients with ET and controls with no history of tremor were recruited from the authors’ clinics.

Fahn, Tolosa, Marin Tremor Rating Scale1-9 Tremor (rate tremor) 1) At rest (in repose). For head and trunk, when lying down.

The patients were diagnosed using Tremor Investigation Group criteria. Nine of the authors, all movement disorder specialists, videotaped TETRAS exams of one control and at least four patients. Download Atif Aslam Songs Pagalworld there.

Each specialist was asked to video patients with mild, moderate and severe ET so that the videos were evenly distributed over these levels of severity. The TETRAS ADL and performance subscales were performed during each videotaping. Fifty videos (44 patients and 6 controls) were compiled in random order to a set of DVDs and mailed to the same specialists and one other. Each specialist rated all 50 videos.

Due to omissions in some of the videos, some of the test items could not be scored for every video. Four of the ten video raters had no experience or training in TETRAS, and nearly all video omissions came from these four raters.
