Background: Hallux valgus (abductovalgus), an irreversible foot deformity, is defined in the International Classification of Disease (ICD) as an acquired deformity of toes (big toe). It is characterized by lateral deviation of the hallux and medial deviation of the first metatarsal. Another term, Bunion, which is often used to describe the same condition, more preciously describes the enlargement and chronic swollen of the medial projected eminence. Almost hallux valgus deformity leads to progressive kinematic impairments, balance dysfunction, and increasing the risk of falls that has become a growing concern worldwide. Hallux valgus influences on foot kinematics, and musculoskeletal articulations` axis has been described in some detail, its effect on the hallux valgus remains poorly understood. Severity of hallux valgus and extend of its progression fortunately influences static and dynamic balance, postural stability in addition positively associated with extra painful complains those accompanied with excess dysfunctional deficits, aggravated falling incidences. Therefore, comprehensive understood of both kinetics and kinematics of hallux valgus and its severity correlation with both static and dynamic balance, and postural stability permits caregivers valuable chances to conduct the most proper rehabilitation programs.
