Where it crosses is what counts
A strip over the back of the wrist stops it bending forward. Over the palm side, it stops it bending back. A strip that does not cross the joint does nothing for it.

Wrist tape
Rigid cotton tape hardly stretches at all. Lay a strip across a joint and the joint bends only as far as the strip allows.
The strip
Tape it. Then try to bend it.

Draw strips across the wrist · then drag the hand to bend it
Tears clean
The weave tears straight across in your fingers, so there is no looking for scissors between sets.

Tape changes how a joint moves. For an injury, have a physiotherapist tape it.
