Positive Wrist Drop Test
A positive Wrist Drop Test is the presence of weakness and the inability of a patient to maintain this position of the upper limb. Inability to hold the wrist in extended position could indicate the presence of lateral cpicondylitis or paralysis due to radial instability.
Possible atrophy of the wrists may be expected if there is chronic radial nerve lesion.
