Foot Pain in Osteoarthritis

Is pressure time integral a factor?

Publish date:: January 18, 2016

Lower pressure time integral (PTI) was modestly associated with increased prevalence of frequent 1st metatarsophalangeal (MTP) pain at both the hallux and 2nd metatarsal, according to a study of participants in the Multicenter Osteoarthritis Study (MOST). Researchers found:

Feet in the quintile with the lowest hallux PTI had 2.14 times increased odds of 1^st MTP pain.

Feet in the quintile with the lowest 2^nd metatarsal PTI had 1.50 times increased odds of 1^st metatarsal pain.

Cumulative plantar stress was unassociated with 1^st MTP pain.
