Gait and pedobarographic patterns of surgically treated clubfeet.
Gait analysis and pedobarography were done on 58 surgically corrected clubfeet in 40 children. The average age of patients at the time of surgery was 6.7 months. The average age of the children at the time of the gait analysis was 6.1 years. Twenty-two children (32 feet) were 5 years old and younger. Eighteen children (26 feet) were older than 5 years old. Cadence, velocity, duration of single-limb stance, step length, and ground reaction force measurements were not significantly different from normal children. Differences noted in clubfeet were: 1) duration of single-limb stance among bilateral clubfeet did not increase with age; 2) increased ankle plantarflexion between opposite foot-strike and toe-off was not present; 3) the feet were internally rotated throughout (toe-in gait); 4) anterior and lateral ground reaction force measurements revealed differing trends with age; and 5) mid- and forefoot pressures increased in the surgically treated group. Gait analysis and pedobarography could detect more subtle abnormalities in corrected clubfeet and provide more objective assessments of persistent deformities.
