A diminished motion in the first metatarsophalangeal (MTP) joint is termed what?

The term for diminished motion in the first metatarsophalangeal joint is hallux limitus. This condition refers specifically to a limitation in the range of motion of the joint, particularly during the extension phase, which can affect a person's ability to walk or run effectively. Hallux limitus can lead to pain and stiffness, especially during activities that require pushing off the big toe.

Understanding this condition is crucial for therapeutic shoe fitting as it can inform the choice of footwear that accommodates limited motion while still providing adequate support and comfort. It differentiates itself from other conditions such as hallux rigidus where there is a more significant restriction of motion or even complete loss of movement at the joint. In contrast, hallux valgus involves a deviation of the toe rather than a limitation of motion, and claw toe is characterized by a different joint position rather than motion restriction.

By recognizing hallux limitus, practitioners can tailor their fitting practices to better meet the specific needs of clients affected by limited range of motion at the MTP joint.
