Significance
- Propulsion efficiency
- Forefoot load transfer
- Gait mechanics
Normal Value
- 60–90° dorsiflexion

About
1st Metatarsophalangeal Joint Excursion describes how much the big toe can move upward and downward relative to the first metatarsal. This motion is critical during walking, as adequate dorsiflexion allows the body to progress forward over the foot and create efficient push-off.
If dorsiflexion is limited, forward progression is restricted and compensations may occur in the foot, ankle, or proximal joints. Excessive or uncontrolled motion may reduce stability during propulsion and alter load distribution through the forefoot.
Effect of Deviation
Limited dorsiflexion may impair push-off and lead to compensatory gait patterns, while excessive motion may reduce forefoot stability and alter loading during propulsion.
