Social anxiety, tremor severity, and tremor disability: a search for clinically relevant measures.

Background. While social anxiety has been reported among essential tremor (ET) patients, very little is known about the relation between self-report measures of social anxiety, tremor severity and disability, and cognition. Methods.

Prevalence and reporting of near-point binocular convergence and acuity vision deficits in potential research participants.

Visual abilities at near-point distances of 200 self-reported normal vision college students were assessed. Results show that normal visual functioning with no deficits is the exception. The most common visual deficits observed involved binocular lateral posture and fusion convergence deficits.

Validity of clinical and patient ratings of tremor disability among older adults.

Objective: To evaluate the validity of the clinical tremor disability interview using a performance-based measure, patient ratings of tremor disability, and bedside tremor severity ratings of upper extremity (UE) action/intention (A/I) and postural (P) tremor.

Method: Sixteen older adult essential tremor patients (mean age=75.4 years, sd=5.
