Technology and Equipment
Many athletics events require specific sports equipment for example, the discus, shot or javelin. In addition athletes may use certain assistive devices as specified in the IPC Athletics rules. This technology continues to advance at a rapid rate.
Wheelchairs are considered to be sports equipment in track and field events. Athletics wheelchairs tend to be very lightweight. The dimensions and features of wheelchairs are clearly specified in the IPC Athletics rules.
Prosthetic devices may be used by amputees. These have been specifically developed to withstand the demands of sports competition. IPC rules require the use of leg prostheses in track events; however, the use of prostheses in field events is optional.
Rope tethers or other devices may be used by runners with a visual impairment to link with their sighted guides. Acoustic devices (or a sighted "caller") may be used to indicate take-off in jumping events, throwing target areas, etc.
