title: [Effect of limited joint mobility on plantar pressure in patients with type 1 diabetes mellitus].
abstract: Limited joint mobility (LJM) in the foot as well as the relationship of LJM and plantar pressure have not been well examined in patients with Type 1 diabetes mellitus. Pronation of the foot during stance phase is helping to absorb the shock of impact. Pronation of the foot is inevitably connected with abduction and dorsiflexion of the foot. We investigated the relationship of LJM and plantar pressure in 50 patients with Type 1 diabetes mellitus (age 40 +/- 11 years, duration of diabetes 23 +/- 10 years, HbA1c 8.2 +/- 1.1%) and the differences in joint mobility between these patients and 44 nondiabetic controls (age 35 +/- 10 years). Joint mobility was measured with a pocket-goniometer; plantar pressure was measured with a pedography platform during walking about barefoot. Statistical analysis showed a significant correlation between range of motion at the talocrural joint and the plantar pressure under the metatarsalheads 2-5, and at the right metatarsophalangeal joint 1 and the plantar pressure under the MTHs 4-5 respectively in diabetic patients. That means, the smaller the range of motion, the higher the plantar pressure. The range of motion in diabetic patients was smaller at the talocrural and metatarsophalangealjoint 1 than in controls. Increase of plantar pressure can be caused by LJM because it impares the shock absorbing capability of the forefoot.
