Abstract:

Hallux valgus deformity is a three-dimensional complex deformity characterized by lateral rotation of the first metatarsophalangeal joint and medial rotation of the proximal phalanx, accompanied by pain, swelling, and the presence of a bunion. Hallux valgus deformity is more common in women than men and its prevalence increases with age. Intrinsic and extrinsic factors are believed to play a role in developing hallux valgus deformity, but the exact cause is still unknown. Plantar pressure, defined as the pressure exerted by individuals on the soles of their feet when standing, has recently been accepted as a reliable biomechanical parameter for investigating and diagnosing various foot disorders. Plantar pressure measurements during standing, walking, or other activities provide detailed information for evaluating deformities involving the ankle, knee, hip, back, and other pathomechanics. They also provide targeted measurement results for monitoring the progression of deformities. Some research groups acknowledge the potential of plantar pressure distribution technology for diagnosing and analysing different foot abnormalities. Pedobarographic analysis, performed in static and dynamic modes, has been widely used in the literature to measure plantar pressure in individuals with hallux valgus deformity. However, in some studies, pressure-sensing insoles have also been used. When examining the literature based on the knowledge accumulated from the past to the present, there is no consensus on the relationship between hallux valgus and plantar pressure, and different views have been put forward.
