Injuries associated with unpowered scooters have increased dramatically since May 2000. These scooters are a new version of the foot-propelled scooters first popular during the 1950s. Most scooters are made of lightweight aluminum with small, low-friction wheels similar to those on in-line skates. They weigh <10 pounds and fold for
easy portability and storage. Up to 5 million scooters are expected to be sold in 2000, an increase from virtually zero last year (Consumer Product Safety Commission [CPSC], unpublished data, 2000). This report summarizes the results of a
descriptive analysis of scooter-related injuries during the past 34 months and provides recommendations
to reduce these injuries.
CPSC and CDC analyzed preliminary data from CPSC's National Electronic
Injury Surveillance System (NEISS) from January 1998 through October 2000 and the
and Potential Injury Incident File (IPII) during
January--October 2000. NEISS is a probability sample of 100 U.S. hospitals with 24-hour emergency departments (EDs) and
more than six beds. NEISS collects data from these hospitals on all persons seeking
treatment for consumer product-related injury in the hospitals' EDs. Estimates of injuries in
the United States associated with specific consumer products or activities can be made
from NEISS data. Data were weighted according to the probability of hospital selection in
the NEISS sample to provide estimates for the U.S. population
(2). IPII consists of anecdotal information reported to CPSC from many sources (e.g., coroners and medical
examiners; newspaper reports; consumer complaints through the CPSC hotline or CPSC's
World-Wide Web site; and referrals from federal, state, and local officials). NEISS was used
to estimate scooter-related injuries, and IPII was used to identify scooter-related
deaths. Because the new scooters were introduced in large numbers into the United
States market in 2000, the 1998 and 1999 data relate to the older versions of scooters.
During January--October 2000, an estimated 27,600* (95% confidence
limits [CL]=22,190--33,010) persons sought ED care for scooter-related injuries. In
August, September, and October 2000, the estimated number of injuries requiring ED care
was 6,529 (95% CL=4,610--8,450), 8,628 (95% CL=6,090--11,170), and 7,359 (95%
CL=5,200--9,520), respectively; October data are incomplete and may change slightly
as additional injury reports are filed. The estimated number of injuries during
August--October represents 80% of the estimated total number of injuries for all of 2000. Each
of the preceding 3 months also exceeded the 12-month total for either 1998 or 1999.
The estimated number of injuries seen in EDs in September 2000 was nearly 18 times
higher than in May 2000.
Approximately 85% of persons treated in EDs were children aged <15 years,
and 23% were aged <8 years; two thirds were male. The most common type of injury was
a fracture or dislocation (29%), of which 70% were to the arm or hand. Other
injuries included lacerations (24%), contusions/abrasions (22%), and strains/sprains (14%).
Forty-two percent of all injuries occurred to the arm and hand, 27% to the head and face,
and 24% to the leg and foot.
Two persons have died while using a scooter. An adult fell and struck his head
while showing his daughter how to ride the scooter. A 6-year-old boy rode into traffic and
was struck by a car.

The findings in this report demonstrate the rapid increase in
injuries associated with riding the new lightweight, folding, unpowered scooters, which are
a fast-growing activity in the United States.
Because these scooters are a recent phenomenon, scientific data about the efficacy of safety equipment to protect
against scooter-related injuries are not available. However, lessons learned from
similar recreational activities (e.g., in-line skating) can guide users in adopting reasonable
safety precautions, such as wearing protective gear.
On the basis of data from in-line skating and bicycling, many of these injuries
have been prevented or reduced in severity had protective equipment been worn.
Helmets can prevent 85% of head injuries (3), elbow pads can prevent 82% of elbow
injuries, and knee pads can prevent 32% of knee injuries
(4). Although wrist guards are effective in preventing injuries among in-line skaters, the protection they provide against injury
for scooter riders is unknown because wrist guards may make it difficult to grip the
scooter handle and steer it.
The public health community can be proactive and support efforts to decrease
scooter-related injury in children by increasing awareness among parents and health-care
providers of the injury potential and the need for safety measures when using
scooters. Many children may not be prepared developmentally to handle the multitask
challenges they may experience while riding a scooter. Changes in the product and rider
behavior also may make riding scooters safer. The mechanisms and circumstances of
scooter-related injury require further research.
On the basis of evidence of injury prevention effectiveness for other related
activities, the following recommendations may help prevent scooter-related injuries:
- Wear a helmet that meets the standard established by CPSC;
- Use knee and elbow pads;
- Ride scooters on smooth, paved surfaces without traffic, and avoid streets
and surfaces with water, sand, gravel or dirt;
- Do not ride scooters at night; and
- Young children should not use scooters without close supervision.
