Acute Posterior Ankle Pain in a Female Recreational Soccer Player

Os trigonum syndrome, a musculoskeletal disorder causing posterior ankle pain, occurs in approximately one in every 13 people. This condition can be challenging for the athletic trainer when evaluating an acute ankle injury. We present a unique case of an os trigonum successfully treated with conservative rehabilitation without a definitive diagnosis.

Control of mobile robotic platforms by handheld devices

The intent of this work was to develop a mobile robotic platform that was controlled by a Palm Pilot PDA. Advances in consumer electronics are producing powerful yet small handheld devices. Some of these devices present quasi-PC capabilities for a fraction of the cost; furthermore, they are compact enough that they fit in all but the smallest of platforms. The platform prototype built for testing purposes has a differential-drive configuration to provide simple but agile movement control. The sensor package consisted of two infrared ranging sensors mounted on servomotors that provide a wide area of detection. Building such a platform involved selection of hardware, circuit integration and software development. The software suite selected to develop code for the Palm Pilot was CodeWarrior, a C compiler that can generate code in Palm-native PRC files.
