【Technical descriptions】 【Shockwave application】The derma-PACE device is set at E2 @ 4 Hz with the energy level at 0.11 mJ/mm² energy flux density. The dosage of shockwave is wound size dependent. The treatment area includes the actual wound area extended 1.0 cm periphery in every direction. The number of pulses = treatment area (cm²) x 8, but in any case at least 500 shocks. The treatment is performed twice/week for a total of 6 treatments.
