1st MTP Joint ROM
The first metatarsophalangeal joint is critical for normal ambulation and restricted range of motion at this joint will impact upon the toe off phase of gait. For normal functioning, the first MPJ should have a minimum of 35 to 40 degrees of dorsiflexion, although expected range would usually be 70-90 degrees. Normal plantarflexion range is around 45 degrees. To test range of motion at the first MPJ, take one hand to stabilize the first metatarsal, just proximal to the metatarsal head with the other hand take the proximal phalanx of the hallux move the joint into dorsiflexion and plantarflexion.
