Impacts of low-energy extracorporeal shockwave therapy on pain, pruritus, and health-related quality of life in patients with burn: A randomized placebo-controlled study

Abstract Background The management of post-burn pain and pruritus remain a potent challenge because of their bad effects on health-related quality of life (HRQOL). The main purpose of this study was to evaluate the impacts of low-energy extracorporeal shockwave therapy (low-energy ESWT) in the management of pain, pruritus, and HRQOL in patients with burn. Methods Forty-five adult patients with burn, their age ranged from 18 to 55 years, were included in the study, they randomly assigned into 22 patients in the study group (low-energy ESWT) and 23 patients in the placebo group. The study group received low-energy ESWT (0.05–0.20 mJ/mm 2 , a frequency of 4 Hz with total shocks from 1000 to 2000 shocks) once per week for 4 successive weeks, while the placebo group received ESWT without energy. Both groups received traditional physical therapy program of selective different exercises (respiratory, range of motion, endurance, strengthening, balance, mobilization, stretching, and gait training) 3 days per week for 4 weeks. Numerical Rating Scale (NRS) for pain and for pruritus, Pressure Pain Threshold (PPT), 12-Item Pruritus Severity Scale (12-PSS), and Burn Specific Health Scale-Brief (BSHS-B) were measured before and after treatment procedures in both groups. Results NRS were decreased significantly in the study group than in the placebo group (P   0.05). Conclusion The findings suggest that low-energy ESWT with traditional regular physical therapy may relive post-burn pain and pruritus, and improve HRQOL, particularly in adult patients with burn.
