Photobiomodulation therapy in neuroischaemic diabetic foot ulcers: a novel method of limb salvage

Objective: Low-level laser therapy (also known as photobiomodulation therapy, PBMT) promotes accelerated healing of diabetic foot ulcers (DFUs), thereby preventing the risk of future complications and amputation. The aim of this study was to determine the effect of PBMT, with structured, graded mobilisation and foot care, on DFU healing dynamics. Method: Patients diagnosed with type 2 diabetes, diabetic peripheral neuropathy and presenting with a chronic neuroischaemic DFU, were treated with PBMT using scanning and non-contact probe methods. The DFU was clinically observed and the area measured every seven days until complete healing. Neuropathic parameters were also measured. The PBMT was administered until complete closure of the DFU and patients also undertook a programme of graded mobilisation. Results: A total of 17 participants were recruited, with a mean age of 69±8 years, and a mean duration of diabetes of 13±5 years. Mean complete closure time was 26±11days. In addition, a mean reduction of the s...
