✦ Synopsis

Video segment 1 is entitled ''idiopathic senile bilateral postural tremor of hands.'' It shows the upper body of a patient with tremor, with his arms and hands resting on his thighs and then holding them outstretched in front of him. Both a front and lateral view are captured in this approximately 1-minute video clip.

On posture there is a high frequency (if the translation of speed recording is correct) bilateral, symmetric arm tremor of moderate amplitude. The tremor affects the fingers, being more distal than proximal and has a slight re-emergent pause. When the arms are resting on the thighs, there also appears to be a rest tremor component, more on the right than the left (although the arms are not fully supported), of similar frequency and of mild-to-moderate amplitude. There appears to be no prominent involvement of the thumb by tremor, although this is not properly assessed. Some of the spontaneous movements appear to be normal including elevation of the left hand, although on the lateral view the right hand has delayed initiation of movement and elevation is hypometric with a 2-phase movement.

No other details of the neurological examination of tremor are shown; in particular, whether or not the tremor shows some positional specificity or is present during writing or on goal-directed movements. Furthermore, it is not clear if other body parts are affected by tremor, for example the legs, the tongue, or the voice. It would also be important to assess for signs of bradykinesia, dystonia, cerebellar signs, eye movement abnormalities, muscle wasting, neuropathy, and cognitive or psychiatric involvement.
