Necessary dorsiflexion of the first metatarsophalangeal joint during gait.

Previous studies of first metatarsophalangeal joint range of motion have resulted in varying values for dorsiflexion of this joint. These values reflect assisted dorsiflexion of the first metatarsophalangeal joint, which has been believed to be the same value that would be obtained during the toe-off phase of gait. These values range from 60 degrees to 90 degrees. This study attempts to obtain measurements during toe-off and to compare obtained values with those of assisted dorsiflexion from the previously mentioned studies.
