We commonly use a 'check-rein' type taping for the prevention of elbow hyperextension with footballers and throwers. 3 stage taping: anchor straps proximally and distally; about 10-15cm prox and distal of the elbow joint (circular, and therefore NOT tight). Then bend the elbow to about 20degrees more flexion than you plan to stop his elbow at. Now, straps from one anchor to the other in a criss-cross formation (about 3-6 of these). Finally, just anterior to the elbow where there is a gap between the skin and the tape, tape around the exposed tape, and tape over the anchor straps again to lock these in. Hope this makes sense.
