This study demonstrates a high prevalence of EIB in collegiate cross-country runners (at least 14%) and that reported symptoms are a poor predictor of actual EIB.

fax (914) 993-4292. Multijoint arm movements of individuals with Huntington's disease (HD) were examined using three-dimensional kinematic analysis. Six HD patients with chorea and four healthy subjects performed pointing movements to a 2.5 cm target positioned at three distances in the sagittal plane, two of which required trunk motion. Healthy subjects moved in relatively straight hand paths to the targets. All HD patients produced curved hand paths, in which they brought their hand first upward and then outward to the target. Healthy subjects made single smooth movements, while HD patients made large initial movements followed by multiple submovements as the hand honed in on the target. Lower functioning HD patients had particular difficulty moving to the farthest target, which required the greatest amount of trunk motion. Although the HD patients had longer movement times across all conditions, their initial velocity was often similar to that of the healthy subjects. This suggests that bradykinesia is related to the production of submovements, rather than a deficit in initial force production. The presence of submovements in Huntington's disease might reflect a deficit in controlling deceleration of the limb or an adaptive strategy to maximize accuracy.

There is a heightened awareness of terrorism in this country. There always remains the possibility of nonterrorist disasters at sporting venues. The team physician will be among the first medical responders to a disaster at a sporting venue. By being involved in the creation of an emergency action plan, learning the incident command system, understanding triage, and obtaining basic trauma life support skills, the team physician can be prepared to respond to mass casualty incidents at sporting events.
