Diabetic foot ulcers (DFUs) are deep tissue lesions associated with ischaemic, neuropathic, or combined neuroischaemic abnormalities and are a leading cause of morbidity and mortality. Of concern is that DFUs affect multiple areas of a person's functioning, including both physical and psychological distress. For example, inactivity due to a DFU can cause feelings of frustration, anger and guilt in patients. This distress has the potential to impair the immune response as well as impacting the quality of life (QoL).
