Echo planar imaging sequence was performed at rest, during dorsal flexion and during plantar flexion.

By exerting tension on the flexor tendon, by means of passive dorsal flexion of the member, evidence of hyperesthesia may be detected.

Undue dorsal flexion is prevented by the deep flexor tendon (perforans) and volar flexion is inhibited by the extensor of the digit (extensor pedis).

26-Extremedorsal flexion said to have resulted from an attack of distemper.
