Lower pressure time integral slightly associated with increased first metatarsophalangeal pain

Recently published results showed an increased prevalence of frequent first metatarsophalangeal pain at the hallux and second metatarsal was ‘modestly’ associated with lower pressure time integral.
Researchers assessed plantar stress and first metatarsophalangeal pain for 2,589 legs of patients with data in the Multicenter Osteoarthritis Study. Researchers asked all patients if they had pain, aching or stiffness at the first metatarsophalangeal joint on most days for the past 30 days. Researchers also quantified pressure time integral as participants walked on a pedobarograph and obtained mean steps per day using an accelerometer.
Overall, results showed 14.7% of patients reported first metatarsophalangeal pain. Researchers found a 2.14-times increased odds of first metatarsophalangeal pain among feet in the quintile with the lowest hallux pressure time integral. Similarly, results showed a 1.50-times increased odds of first metatarsophalangeal pain among feet in the quintile with the lowest second metatarsal pressure time integral. First metatarsophalangeal pain was not associated with cumulative plantar stress, according to results. – by Casey Tingle
