A novel gait platform to measure isolated plantar metatarsal forces during walking.
Summary of "A novel gait platform to measure isolated plantar metatarsal forces during walking."
A new gait platform described in this report allows an isolated measurement of the vertical and shear forces under an individual metatarsal head during barefoot walking. The apparatus incorporated a customized tactile force sensor and a high-speed camera system, which enabled easy identification of a single anatomical landmark at the forefoot's plantar surface that is in contact with the sensor throughout stance. After calibration, the measured peak forces under the 2nd MTH showed variability of 3.7%, 9.2%, and 8.9% in vertical, anterior-posterior, and medial-lateral directions, respectively. The device therefore provides information about the magnitude and timing of such local metatarsal forces, and has been shown to be of significant research and clinical interest. Its ability to achieve this with a high degree of accuracy ensures its potential as a valuable research tool.

Medical and Biotech [MESH] Definitions
Fasciitis, Plantar
Inflammation of the thick tissue on the bottom of the foot (plantar fascia) causing HEEL pain. The plantar fascia (also called plantar aponeurosis) are bands of fibrous tissue extending from the calcaneal tuberosity to the TOES. The etiology of plantar fasciitis remains controversial but is likely to involve a biomechanical imbalance. Though often presenting along with HEEL SPUR, they do not appear to be causally related.
Metatarsophalangeal Joint
The articulation between a metatarsal bone (METATARSAL BONES) and a phalanx.
Heel Spur
A bony outgrowth on the lower surface of the CALCANEUS. Though often presenting along with plantar fasciitis (FASCIITIS, PLANTAR), they are not considered causally related.
Foot Bones
The TARSAL BONES; METATARSAL BONES; and PHALANGES OF TOES. The tarsal bones consists of seven bones: CALCANEUS; TALUS; cuboid; navicular; internal; middle; and external cuneiform bones. The five metatarsal bones are numbered one through five, running medial to lateral. There are 14 phalanges in each foot, the great toe has two while the other toes have three each.
Gait Apraxia
Impaired ambulation not attributed to sensory impairment or motor weakness. FRONTAL LOBE disorders; BASAL GANGLIA DISEASES (e.g., PARKINSONIAN DISORDERS); DEMENTIA, MULTI-INFARCT; ALZHEIMER DISEASE; and other conditions may be associated with gait apraxia.

Are diurnal changes in foot sole sensation dependent on gait activity?
The foot sole is loaded during stance and gait and plantar cutaneous mechanoreceptors sense the local stress distribution. It is not clear whether the perception thresholds of these mechanoreceptors c...
