Inter‐segmental foot kinematics during gait in elderly females according to the severity of hallux valgus

Abstract

The objective of this study was to find the effect of hallux valgus (HV) deformity on the inter-segmental motion of the foot using an MFM with a 15-marker set (DuPont Foot Model, DuFM) in comparison with age and sex controlled healthy adults. Fifty-eight female symptomatic HV patients and 50 female asymptomatic older female volunteers were included in this study. According to the radiographic hallux valgus angle (HVA), the study population was divided into severe HV (SHV, HVA ≥ 40°, n = 25), moderate HV (MHV, 20°≤ HVA < 40°, n = 47), and control (CON, n = 36). MHV group was divided into symptomatic MHV group (S-MHV, n = 33) and asymptomatic MHV group (A-MHV, n = 14) according to the symptoms associated with HV. For temporal parameters, gait speed and stride length were diminished according to the severity of HV deformity. Sagittal range of motion of hallux and hindfoot decreased significantly in SHV group. Loss of push-off during the preswing phase was observed and forefoot adduction motion during terminal stance was decreased in SHV group. In a subgroup analysis of MHV, asymptomatic HV minimally affects gait and inter-segmental motion during gait. HV deformity affects gait parameters and inter-segmental motion of the foot during gait in proportion to the severity of the deformity. However, the effect of MHV itself on foot kinematics might be limited while pain or arthritic change of the joint might cause changes in gait in patients with symptomatic HV.

Examination of gait characteristics and related factors in elderly subjects with and without hallux valgus

“…A previous study that focused on the gait of participants with hallux valgus reported decreased ground reaction forces [REMOVED DUE FIELD]in subjects with higher hallux valgus angles. 22 ) Further, subjects with hallux valgus-related pain showed a decrease in the ground reaction force. Therefore, we excluded patients with painful hallux valgus in the current study.…”

The Syndesmosis Procedure Correction of Hallux Valgus Feet Associated With the Metatarsus Adductus Deformity

“…Hallux valgus deformity is also common but acquired later in life. While MA deformity is largely static and not usually a functional problem for the foot (4), HV deformity is progressive and can compromise biomechanics of the foot (23)(24)(25)(26)(27). MA deformity seldom requires surgical treatment, but HV feet may need to restore their proper mechanical function for walking (28)(29)(30).…”

Change in intersegmental foot and ankle motion after a high tibial osteotomy in genu varum patients

“…For the evaluation of intersegmental foot motion, we used the DuPont foot model. 17,18 The placement of the markers, definition of the coordinate systems based on these markers, and method of calculating the joint rotation and arch parameters have been described previously. 19,20 In summary, the placement of the 15 markers was as follows: two markers on the knee (lateral and medial), three markers on the tibial shank (upper, front, and rear), two markers on the ankle (lateral and medial), two markers on the hindfoot segment (heel and distal), two markers on the midfoot segment (navicular and cuboid), three markers on the forefoot segment (MTH1, toe, and MTH5), and one marker on the hallux.…”

“…A single operator placed reflective markers from the DuPont foot model. 18 Baseline static data were obtained in a calibration trial with the feet positioned flat on the ground and parallel to each other in the coronal axis. Subjects were asked to walk barefoot at their usual speed along a 9-m track.…”

“…Gait data were collected at the Human Motion Analysis Laboratory of Seoul National University Hospital. For the evaluation of intersegmental foot motion, we used the DuPont foot model 17,18 . The placement of the markers, definition of the coordinate systems based on these markers, and method of calculating the joint rotation and arch parameters have been described previously 19,20 …”
