This Lexicon/Dictionary is an on-line tool for looking up definitions for over 1,000 clinical, technical and biomechanical terms. This P&O Lexicon provides cross-indexing in English, German, French, Spanish, Chinese, Japanese, Turkish, and Vietnamese. Therefore, this tool can also be used for translation. Thank you to The Ottawa Hospital Rehabilitation Centre for continued support for this initiative, Fangwei Zeng for technical support, and the many volunteers who translated and helped to develop the database of terms and definitions.
