Abstract
Mobility is impaired during arthritis. In order to study the causes of the mobility impairment, we have examined hamsters with a LPS arthritis in which running is inhibited over a 4–5 day period. Parameters have been examined to determine which correlate with running impairment. Knee diameter, as well as cell infiltration into the surrounding synovial tissue and the accompanying edema, failed to resolve by the time normal mobility was reestablished. Other factors must be primary determinants of mobility.
