One world one burn rehabilitation standard.

According to the World Health Organization (WHO) burns are a huge global health problem resulting in death and devastation to those who survive large burns as they are faced with significant functional limitations that prevent purposeful and productive living. Members of the International Society for Burn Injuries (ISBI) Rehabilitation Committee conducted a needs assessment survey in order to characterize how burn rehabilitation is implemented worldwide and how the international burn rehabilitation community can help improve burn rehabilitation in identified geographic locations which need assistance in rehabilitating burn survivors successfully. The results of this survey indicated that poor and in some cases resource limited environments (RLEs) around the world seem to lack the financial, educational and material resources to conduct burn rehabilitation successfully. It appears that there are vast discrepancies in the areas of education, training and capacity to conduct research to improve the care of burn survivors as evidenced by the variation in responses between the RLEs and developed countries around the globe. In some cases, the problem is not knowledge, skill and ability to practice burn rehabilitation, but rather having the resources to do so due to financial difficulties.

Detection of changes of scar thickness under mechanical loading using ultrasonic measurement.

The intervention of pressure therapy on management of hypertrophic scar (HS) after burn is based on the theoretical assumption that the mechanical force added onto the scar tissue will reduce the growth of myofibroblasts which create the collagen clusters and the interstitial space, and to realign fibrous tissues, thus reducing the thickness of HS. In this experimental study, a high frequency ultrasound imaging system (12 MHz) was applied to measure the real time changes of thickness of the post burn HS under a mechanical loading system with similar pressure generated to the scar tissue. The validity of the ultrasound system in measurement of the changes of scar thickness underneath the tissue was tested on the porcine skin in vitro followed by measurement of human skin in vivo. Results showed that the ultrasound measurement of thickness had both good validity (r(2)=0.98, p<0.0001) and good intra-rater reliability (ICC=0.89). Then, the system was used to test the thickness of 14 human HS samples in vivo among 7 subjects. External loading force with similar pressure range (10-45 mmHg) was then applied to these scar samples via ultrasound probe with rectangular contacting area at 4 cm(2) and each loading force was maintained unchange for 2 min over the scar tissue. The real time scar thickness was documented. Results showed that the mean scar thickness was found to be significantly decreased when the loading force applied was increased from 5 to 35 mmHg (with 10 mmHg interval) (p<0.001). A significant negative correlation between the pressure level and scar thickness was observed (r(2)=0.96, p=0.005). The decline of thickness was found more significant between 0 mmHg and 15 mmHg. The findings were in line with the postulate that pressure therapy is effective in reducing the thickness of HS. A long term followup study should be administered to determine the prolonged effect of pressure intervention.

The effect of a computerized visual perception and visual-motor integration training program on improving Chinese handwriting of children with handwriting difficulties.

This study aimed to investigate the effect of a computerized visual perception and visual-motor integration training program to enhance Chinese handwriting performance among children with learning difficulties, particularly those with handwriting problems. Participants were 26 primary-one children who were assessed by educational psychologists and occupational therapists to have handwriting difficulties. They were matched according to their age and then randomly assigned into either the control group or the experimental group. Subjects in the experimental group (n=13) would receive eight sessions of computerized visual perception and visual-motor integration training together with a home training program while those in the control group (n=13) would only receive conventional handwriting training by teachers, which focused mainly on remedial handwriting exercises. Results from repeated measure ANOVA revealed that children in the experimental group showed improvements in their visual perception skills as well as in their handwriting time. Both the "On Paper" time and "In Air" time of this group were improved when compared to the control group. However, no significant differences were found in visual-motor integration skill and handwriting legibility between the two groups after the intervention. This computerized training program focusing on visual perception and visual-motor integration training appeared to be effective in enhancing the handwriting time among children with handwriting difficulties. However, the training program did not seem to improve the legibility of children.

The effect of a job placement and support program for workers with musculoskeletal injuries: a randomized control trial (RCT) study.

BACKGROUND: This is a randomized clinical trial (RCT) to investigate the efficacy of a job placement and support program designed for workers with musculoskeletal injuries and having difficulties in resuming the work role. The program was planned to help injured workers to successfully return to work (RTW) by overcoming the difficulties and problems during the process of job seeking and sustaining a job using a case management approach. METHODOLOGY: A total of 66 injured workers were recruited and randomly assigned into the job placement and support group (PS group) or the self-placement group (SP group). A three-week job placement and support program was given to subjects in the PS group while subjects in the control group (SP group) were only given advice on job placement at a workers' health center. The PS program was comprised of an individual interview, vocational counseling, job preparation training, and assisted placement using the case management approach. The Chinese Lam Assessment of Stages of Employment Readiness (C-LASER), the Chinese State Trait and Anxiety Inventory (C-STAI), and the SF-36 were the outcome measures for the two groups before and after the training program to observe the changes in subjects' work readiness status, emotional status and their health related quality of life pre- and post-training program. The rate of return to work was measured for both groups of subjects after the training program. RESULTS: The results indicated that the rate of success in RTW (73%) was significantly higher in the job placement (PS) group than that of the self-placement (SP) group (51.6%) with P < 0.05. Significant differences were also found in C-STAI (P < 0.05), SF-36 (P < 0.05) and C-LASER scores on action (P < 0.05) between the two groups. CONCLUSION: The job placement (PS) program appeared to have enhanced the employability of injured workers. Workers who participated in the program also showed higher levels of work readiness and emotional status in coping with their work injuries.

A randomized controlled trial of surgery vs steroid injection for carpal tunnel syndrome.

BACKGROUND: Decompressive surgery and steroid injection are widely used forms of treatment for carpal tunnel syndrome (CTS) but there is no consensus on their effectiveness in comparison to each other. The authors evaluated the efficacy of surgery vs steroid injection in relieving symptoms in patients with CTS. METHODS: The authors conducted a randomized, single blind, controlled trial. Fifty patients with electrophysiologically confirmed idiopathic CTS were randomized and assigned to open carpal tunnel release (25 patients) or to a single injection of steroid (25 patients). Patients were followed up at 6 and 20 weeks. The primary outcome was symptom relief in terms of the Global Symptom Score (GSS), which rates symptoms on a scale of 0 (no symptoms) to 50 (most severe). Nerve conduction studies and grip strength measurements were used as secondary outcome assessments. RESULTS: At 20 weeks after randomization, patients who underwent surgery had greater symptomatic improvement than those who were injected. The mean improvement in GSS after 20 weeks was 24.2 (SD 11.0) in the surgery group vs 8.7 (SD 13.0) in the injection group (p < 0.001); surgical decompression also resulted in greater improvement in median nerve distal motor latencies and sensory nerve conduction velocity. Mean grip strength in the surgical group was reduced by 1.7 kg (SD 5.1) compared with a gain of 2.4 kg (SD 5.5) in the injection group. CONCLUSION: Compared with steroid injection, open carpal tunnel release resulted in better symptomatic and neurophysiologic outcome but not grip strength in patients with idiopathic carpal tunnel syndrome over a 20-week period.
