Design outcomes

Primary

Measure	Time frame
To assess the effects of icing (adverse effects) and whether icing plus oxygen or icing plus HBO can reduce the adverse effects of icing, icing, icing plus oxygen and icing plus HBO intervention groups are set up, with no intervention, oxygen only and HBO only groups as controls. Then, transcutaneous oxygen partial pressure measurements, blood flow measurements, skin temperature measurements and foot and ankle joint volume measurements will be performed.	—
