Snoezelen: a controlled multi-sensory stimulation therapy for children recovering from severe brain injury.

OBJECTIVE: To investigate the effects of Snoezelen therapy on physiological, cognitive and behavioural changes in children recovering from severe traumatic brain injury (TBI). METHODS: An observational study was conducted to assess the physiological, cognitive and behavioural changes of children recovering from severe TBI while receiving Snoezelen therapy. Fifteen subjects completed the pre- and post-Snoezelen treatment measurements computed over 10 consecutive sessions. Physiological, cognitive and behavioural measures were administered. Data was collected prospectively on each session in the Snoezelen room and were analysed by calculating the difference between pre- and post-treatment measurements for each Snoezelen session. RESULTS: Results revealed significant changes on physiological measures. Heart rates decreased for each subject in each treatment session and were found to be significant (p = 0.032). Muscle tone was decreased in all the affected extremities (right upper extremity p = 0.009, left upper extremity p = 0.020, right lower extremity p = 0.036 and left lower extremity p = 0.018). Agitation levels decreased over time and the overall cognitive outcome measures showed significant improvement when comparing the beginning of treatment with the end. CONCLUSION: This study revealed a beneficial use of Snoezelen therapy with children recovering from severe brain injury. However, there continues to be a critical need for evidenced-based research for this patient population and others in this multi-sensory environment.

Outcome of motorcycle riders at one year post-injury.

OBJECTIVE: There is little information about the long-term effects of injury on victims of motorcycle crashes. Following the repeal of the mandatory helmet law in Florida, we studied the impact of crashes on riders and their outcomes one year post-injury. SUBJECTS: All patients involved in a motorcycle crash over a six-month time period were assessed at one year post-injury. Demographic information, health status, motorcycle and helmet usage, and employability were surveyed. RESULTS: There were 94 patients evaluated at our center for the first six-month period following the repeal of the helmet law, where 50 (56%) were wearing a helmet at the time of injury. Of the 94, we were able to contact 45 (48%) at one-year follow up. Fourteen (31%) of those contacted were not wearing a helmet at the time of their crash. At one year post-injury, 23 (51%) reported physical deficits, while 39 (86%) were working. Only 12 (27%) were riding a motorcycle again, and 11 (92%) were wearing a helmet. CONCLUSIONS: Motorcycle riders at one year post-injury continue to experience physical deficits related to their accidents. There is a small percentage of riders that resume riding a motorcycle after injury. Being involved in a motorcycle accident has deterred the injured rider from riding a motorcycle again at one year post-injury.

Pediatric pedestrian trauma study: a pilot project.

OBJECTIVE: To evaluate the implementation of the WalkSafe Program, a school based educational injury prevention program for children grades Kindergarten through 5. METHODS: A randomized comparative design was used for this study. The study was conducted in two high-risk urban school districts, which were chosen based on the geographic areas with the highest pedestrian injury and fatality rates. Four elementary schools (two in each district) were identified as potential study sites. Two intervention schools, one in each school district, were randomly chosen to receive the WalkSafe program; the other two schools served as controls, and received no intervention. The data was collected within the classroom setting for both the intervention and control schools. All elementary school children were administered the same pedestrian safety questionnaire as a pre-test, post-test and at three months following the intervention. RESULTS: A total of 2300 children participated in the WalkSafe program. The intervention (I) schools showed significant improvement in post-test scores then the control (C) schools (p = 0.012), and the (I) schools were able to maintain their test scores as reflected in a three-month follow-up evaluation (p = 0.47). Grades 3-5 of the (I) schools showed significant improvement in their test scores over grades K-2 (p < 0.0001). CONCLUSION: The WalkSafe program was shown to improve the pedestrian safety knowledge of elementary school children. Future research will include implementing the WalkSafe program at each elementary school within a single high-risk district.

The impact of a repealed motorcycle helmet law in Miami-Dade County.

OBJECTIVE: To study the impact of helmet nonuse in motorcycle crashes after the repeal of a mandatory helmet law in the state of Florida. METHODS: We prospectively studied all patients evaluated at the University of Miami/Jackson Memorial Medical Center from July 1, 2000, through December 31, 2000, involved in motorcycle crashes, and compared them with those seen during the same time period the year before the helmet law change. RESULTS: In 1999, before the repeal of the helmet law, there were 52 cases evaluated at our center compared with 94 after the law change. Helmet usage decreased from 1999 (83%) to 2000 (56%). The number of brain injuries (Abbreviated Injury Scale score > or = 2) during this same time period increased from 18 to 35, and the number of fatalities from 2 to 8. CONCLUSION: The repeal of a motorcycle helmet law significantly increased the number and severity of brain injuries admitted to our trauma center.
