A Randomized Clinical Trial to Study the Effect of Silicone Gel Dressing and Pressure Therapy on Posttraumatic Hypertrophic Scars
ABSTRACT To investigate the effect of pressure therapy (PG), silicone gel sheeting (SGS), and combined therapy on the management of posttraumatic hypertrophic scar (HS) using a randomized controlled clinical trial. A total of 104 subjects with HS mostly resulting from burns and scald injuries (63 men and 41 women; average age: 21.8 +/- 18.7 years) were recruited from Jiangsu People's First Affiliated Hospital in Nanjing, China. The mean scar formation period was 14.9 +/- 30.8 months. All subjects were randomly allocated into four groups, namely the PG, SGS, combined PG and SGS groups, and single-blinded control group for the treatment of 6 months. Standardized scar assessments (pigmentation, vascularity, thickness, pain, and itchiness) were conducted before the intervention, 2, 4, and 6 months of the intervention, and 1 month after completion of the program, respectively, to observe the progress of the treatments. The results showed that the combined therapy seemed to be more effective in improving the thickness of scar after 2 months of intervention (P < .001). After 6 months of intervention, both the combined therapy group and the PG group showed significant improvement in scar thickness. The improvement in scar thickness was most significant in the combined therapy group. SGS was found to be more effective in alleviating the pain and pruritus rather than the scar thickness. This randomized clinical trial has demonstrated the evidence of the effect of combined PG and gel intervention on posttraumatic HS. The PG group showed an improvement in scar thickness too. Further studies are needed to investigate the biomechanical and physiological effect that PG and gel sheeting would exert on the scar tissues.

ABSTRACT: Splinting children and ensuring that children wear the splint can be challenging tasks for both the therapist and the caregiver. Sometimes creativity is needed to create a pediatric splint that is easy to don and stays in place. These authors describe their challenge with pediatric burn patients either not wearing or losing their splint and how they now combine the splint directly into the pressure garment to ensure better patient complianceJournal of Hand Therapy 12/2010; 24(3):277-9.

ABSTRACT: A novel ultrasound (US) platform, consisting of an embedded US transducer connected in series with a circular silicone layer, was developed to evaluate the mechanical properties of human plantar tissues in this study. Force exerted by the foot was determined based on the deformation of the silicone layer, which was measured by US. The platform could capture the deformations of both the silicone layer and plantar tissues simultaneously. The stiffness of the plantar tissue was then extracted from the force-deformation curve. To test the feasibility of the US platform, eight phantom feet with different stiffnesses were tested using this new system. The moduli of the phantom feet were also measured by the tissue ultrasound palpation system (TUPS). The results showed that the phantom stiffness determined using the platform was in linear correlation with the corresponding modulus measured by the TUPS (R2 = 0.8914). The current system can be improved by using several US transducers to perform multiple measurements at the same time for reliable assessment of human plantar tissues in a non-invasive, convenient, and cost-effective way.Instrumentation Science & Technology 05/2011; 39(3):248-260.
