Hitchman LH, Totty JP, Cai P, Smith GE, Carradice D, Chetter IC. Extracorporeal shockwave therapy for diabetic foot ulcers: a feasibility study. J Wound Care. 2023 Mar 2;32(3):182-192.
Design: Single-Centre, Mixed Methods Feasibility Study. Subjects: 22 patients with a Diabetic Foot Ulcers (DFU)
Methods: Patients who met the eligibility criteria underwent standard wound care, and additional ESWT three times over a seven-day period. Focused shockwaves were given at 120shocks/cm2 at 0.1mJ/mm2 Semi-structured interviews were conducted after 4 weeks from treatment allocation to explore participants' experience of undergoing ESWT. Outcomes included: Wound size, DFUs healed at 12 weeks, Quality of life. Results: • The mean attendance at clinic was 90.9% and 65.1% for follow-up. • The mean score for acceptability and tolerability was 9.86±0.48 (95% confidence interval (CI): 9.62-10.01) and 9.15±2.57 (95% CI: 7.87-10.42), respectively. • There were no serious adverse events or side-effects. • Of the DFUs, 45.5% healed during follow-up and QoL scores improved until eight weeks. • Key themes identified from the qualitative interviews were: desire for fast healing; improved QoL; flexibility of new treatments; and accessibility of transport.
Key message: It is possible to recruit and retain patients with DFUs into a trial investigating extracorporeal shockwave therapy (ESWT) and was acceptable and tolerable for patients. Wound healing and quality of life scores increased until 8 weeks with ESWT.
