The trackers work on areas of contrast and expect some degree of consistency, which the "flashes" of light are probably throwing off.
If you cannot find a trackable point on the hand you will need to take steps to correct the contrast (you could branch off the footage with a set of nodes that filter the image in some way to create something that might look bad to a human but provides good contrast for the tracker, then simply not use that branch to produce your final output - just track from it), or use different points to track different sections of the footage (start tracking and watch for the tracker to start wandering, then find a point just before it goes bad and restart the track from there with it tracking from a different point).
If there are parts of the footage where the contrast is so bad that it simply won't track, you may have no choice but to manually tweak the path for that part of the footage.
