As said above, massage, use of some aromatherapy oils, anything that may cause cuts or bruising (cuticle, pedicure work).
My main question would be why they are on warfarin and enoxeparin??
Warfarin is a blood thining drug used long term by patients susceptible to Blood clots (due to history of previous clots or altered heart rhythms) or those that have had a replacement heart valve, (initial reason for replacement should also be considered (infection, rheumatic fever, congenital) Enoxeparin is a blood thinning injection which is short acting in comparison to warfarin and is often only used short term by immobile hospital inpatient to prevent DVT or by new warfarin patients whilst they are obtaining optimal clotting factors and also but only very occasionally used by patients outside of hospital.
Hope this helps
