Clinical Utility of ESWT in Restoring Hand Function of Patients With Nerve Injury and Hypertrophic Scars Due to Burns
Sponsor: Hangang Sacred Heart Hospital
Summary
Joint contractures and nerve injuries are common after hand burns. Extracorporeal shock wave therapy (ESWT) is effective not only for the regeneration of various tissues, including scar tissues, but also for reducing pain and pruritus in patients with burns. Researchers have attempted to explore the effects of ESWT on hand dysfunction caused by nerve injury following burns. The investigators planned to evaluate the effects of ESWT (compared to sham stimulation) on hands with nerve injury and hypertrophic scars and thereby on hand function. The ESWT parameters were as follows: energy flux density, 0.05-0.30 mJ/mm2; frequency, 4 Hz; 1000 to 2000 impulses per treatment; and 12 treatments, one/week for 12 weeks. Outcome measures were as follows: 10-point visual analog scale for pain, Jebsen-Taylor hand function test, grip strength, Purdue Pegboard test, ultrasound measurement of scar thickness, and skin characteristics before and immediately after 12 weeks of treatment.

Interventions
Extracorporeal shock wave therapy (ESWT)
Those in the ESWT group were asked to select the most hypertrophic and retracting scars for treatment. ESWT was conducted using the Duolith SD-1® device (StorzMedical, Tägerwilen, Switzerland), with an electromagnetic cylindrical coil source used to focus the shock wave. ESWT was performed around the primary treatment site, at an intensity of 100 impulses/cm2, an energy flux density (EFD) of 0.05 to 0.30 mJ/mm2, and frequency of 4 Hz. Regarding the volume of treatment, 1000-3000 impulses were administered per session for 12 sessions held at 1-week intervals.
sham stimulation
the sham group was treated using an adapter that had the same shape but did not emit any energy
