Clinical assessment of hand strength using a microcomputer

Grip pattern and finger coordination differences between pianists and non-pianists

“…In the hook grip (Fig. 4), the fingers were semi-flexed in the form of a hook, while the thumb functioned as a support, as if holding the handle of a suitcase or a bucket (Jain et al, 1985). At fast velocity, the volunteer was required to perform the finger flexion and extension movements as quickly as possible, repeating each movement in a maximum time of 1.5 s. At slow velocity, the volunteer was required to perform the movements slowly, taking 4 s to close the fingers, and 4 s to return to the initial position (a total of 8 s for each repetition).…”
