“…A good example of an optical pedobarograph -namely the Sheffield pedobarograph -was first described in 1982 (Duckworth T et al, 1982). Basically, the pedobarograph is made of an illuminated glass plate covered with a plastic sheet.…”

“…In standing, the great toe exerts more pressure than those of the five metatarsal heads and the heel, 1 with a pressure twice that of the total pressure of the other four toes. 2 During walking, as the great toe passively dorsiflexes, the longitudinal arch is raised, the rearfoot supinated, the leg externally rotated, and the plantar aponeurosis tensed.…”

The objective of this study was to evaluate great toe function in maintaining static and dynamic balance. Correlation among great toe length, body height, and balance performance parameters were also investigated. Thirty females (aged 22.1 AE 1.9 years) were tested in two great toe conditions: unconstrained and constrained. Balance testing was done in the following order: (1) static balance, single-leg stance with right or left foot, eyes open or closed; (2) static balance, stance with both feet, eyes open or closed; (3) dynamic balance, left/right or forward/backward, rhythmic weight shifting; and (4) dynamic balance, target reaching test, eight targets within 90% limit of stability. Significant differences were found in sway velocity between the two toe conditions with eyes open or closed in single-leg stance ( p < 0.05). No difference was found between the two conditions while standing with both feet. For rhythmic weight shifting, significant differences in sway velocity were found in toe conditions and in weight-shifting directions ( p < 0.05). As to target reaching, significance was only noted in directional control scores. Great toe length was correlated with subject's height (r ¼ 0.553, p < 0.05). Our results indicate that constraining the great toe deteriorated the subjects' single-leg stance performance and worsened the directional control ability during forward/backward weight shifting. The importance of the great toe in balance may be taken into account in toe amputation or transfer in the future. ß

“…Depicted motion analysis of the first metatarsophalangeal joint in patients with osteoarthritis, reveals instant centers of rotation that are displaced and located eccentrically about the metatarsal head [30]. Higher than average dynamic plantar pressures of the first ray are also observed in symptomatic patients with first metatarsophalangeal joint osteoarthritis [32].…”

The first metatarsophalangeal joint of the human foot may best be classified as an anatomically condyloid synovial juncture. This joint is primarily formed by the rounded head of the first metatarsal bone, in sequence with the shallow concavity of the base of the first proximal phalanx. Whilst there is no dorsal ligament supporting or stabilizing the first metatarsophalangeal joint, the structure is largely secured by both the adjoining collateral ligaments and the plantar metatarsal ligament respectively. The movements permitted at the first metatarsophalangeal joint are inclusive of flexion, extension, abduction and adduction. This articulation is particularly subjected to a significant amount of stress during the weight-bearing activity of human locomotion, and is consequently susceptible to the precipitated development of degenerative osteoarthritis through repetitive loading. Such a pathological sequence can elicit marked intra-articular pain and overall functional limitation capacity of the first metatarsophangeal joint. In reference to the disorder of first metatarsophalangeal joint osteoarthritis, commonly referred to as either hallux limitus or hallux rigidus, this review will scrutinize the differential diagnoses, predisposing factors, physical examination traits and clinical management of the condition accordingly.
