To investigate the relationship between cognitive perceptual abilities of elderly drivers based on the Cognitive Perceptual Assessment for Driving (CPAD) test and their accident and penalty histories.
A total of 168 elderly drivers (aged ≥65 years) participated in the study. Participant data included CPAD scores and incidents of traffic accidents and penalties, attained from the Korea Road Traffic Authority and Korea National Police Agency, respectively.
Drivers' mean age was 70.25±4.1 years and the mean CPAD score was 52.75±4.72. Elderly drivers' age was negatively related to the CPAD score (p<0.001). The accident history group had marginally lower CPAD scores, as compared to the non-accident group (p=0.051). However, incidence rates for traffic fines did not differ significantly between the two groups. Additionally, the group that passed the CPAD test had experienced fewer traffic accidents (3.6%), as compared to the group that failed (10.6%). The older age group (12.0%) had also experienced more traffic accidents, as compared to the younger group (2.4%).
Overall, elderly drivers who experienced driving accidents had lower CPAD scores than those who did not, without statistical significance. Thus, driving-related cognitive abilities of elderly drivers with insufficient cognitive ability need to be further evaluated to prevent traffic accidents.

To review the medical utilization in children with cerebral palsy according to age and discern particularities
From January 2007 to December 2007, 10,659 children and adolescents between 1 and 18 years of age who had filed national insurance claims for a diagnosis of cerebral palsy were selected. Age was chosen as an independent variable, and the population was categorized into specific age groups to verify any differences in medical service utilization. Admission duration to rehabilitation, number of visits to rehabilitation outpatient clinics, numbers of admission dates and outpatient clinic visits for general medical services, number of rehabilitation utilizations, and type of rehabilitations treatment were selected as dependent variables. One-way ANOVA was used for statistical evaluation, and analysis was done with SAS software.
In general medical use, adolescences diagnosed with cerebral palsy had the highest mean admission duration (p<0.001). The mean visit day to outpatient clinics for general medical services was highest for infants (p<0.001). In rehabilitation treatment, infants diagnosed with cerebral palsy had the highest mean admission duration (p<0.001). The mean visit day to outpatient clinics for rehabilitation treatment was highest for infants (p<0.001).
Significant differences in use of general and rehabilitation medical services among pediatric age groups with cerebral palsy were evident. This implies that particular attention is necessary when setting up a national medical care policy for patient with cerebral palsy.

Holmes' tremor is a low-frequency rest and intentional tremor secondary to various insults, including cerebral ischemia, hemorrhage, trauma, or neoplasm. Pharmacologic treatment is usually unsuccessful, and some cases require surgical intervention. We report a rare case of Holmes' tremor secondary to left pontine hemorrhage in a 29-year-old Asian male patient who developed 1.6-Hz postural and rest tremor of the right hand. He responded markedly to ultrasonography-guided botulinum toxin type A injection. To our knowledge, this is the first report of Homes' tremor treated with ultrasonography-guided botulinum toxin type A injection with favorable results.

In order to determine the most suitable computer interfaces for patients with high cervical cord injury, we report three cases of applications of special input devices. The first was a 49-year-old patient with neurological level of injury (NLI) C4, American Spinal Injury Association Impairment Scale (ASIA)-A. He could move the cursor by using a webcam-based Camera Mouse. Moreover, clicking the mouse could only be performed by pronation of the forearm on the modified Micro Light Switch. The second case was a 41-year-old patient with NLI C3, ASIA-A. The SmartNav 4AT which responds according to head movements could provide stable performance in clicking and dragging. The third was a 13-year-old patient with NLI C1, ASIA-B. The IntegraMouse enabling clicking and dragging with fine movements of the lips. Selecting the appropriate interface device for patients with high cervical cord injury could be considered an important part of rehabilitation. We expect the standard proposed in this study will be helpful.

To investigate the effect of Comprehensive Hand Repetitive Intensive Strength Training (CHRIST) on upper limb function in children with cerebral palsy using motion analysis.
The subjects in this study included 19 children (10 males, 9 females, mean age=8.8 years) with cerebral palsy. The experimental group (n=10) received CHRIST and general rehabilitation therapy. The control group (n=9) received a home program as well as general rehabilitation therapy. Both groups received 30 sessions of CHRIST or home program training for 60 minutes per session 3 times a week during the 10-week period. The reaching movements were captured by a motion analysis system. Kinematic variables including movement time (MT), mean velocity (MV), normalized jerk score (NJS), mean angular velocity (MAV) and normalized jerk score of the shoulder, elbow and wrist joint with comfortable and fast speed were analyzed between groups and the pre-post training group.
After pre- and post-training experimental group, MT, MV, NJS, MAV of shoulder, elbow, wrist and NJS of elbow and wrist improved significantlyin reaching movement of both comfortable and fast speed (p<0.05). However, After pre- and post-training control group, MV improved significantlyin reaching movement of only comfortable speed (p<0.05). Between two groups, MT and MAV of the elbow at comfortable speed and NJS of the elbow at fast speed were statisticallysignificant (p<0.05).
CHRIST proved to be an effective intervention for improving upper limb extremity function of reaching movement in children with cerebral palsy.
