Area of Science:

• Biomechanics
• Orthopedics
• Gait Analysis

Background:

• Hallux valgus is a common foot deformity.
• Altered foot kinematics during gait can result from hallux valgus.
• Coordination patterns between different foot segments during walking are not fully understood in this population.

Purpose of the Study:

• To investigate the coordination of kinematic movements among the shank, rearfoot, midfoot, and forefoot during gait in individuals with hallux valgus.
• To compare these coordination patterns with healthy controls.

Main Methods:

• Utilized 3D motion capture technology to record kinematic data during walking.
• Analyzed joint angles and segment rotations of the lower limb and foot.
• Applied cross-correlation analysis to assess inter-segmental coordination.

Main Results:

• Individuals with hallux valgus exhibited altered coordination patterns between the shank, rearfoot, midfoot, and forefoot during gait.
• Specific differences were observed in the timing and magnitude of inter-segmental movements.
• These kinematic alterations may contribute to the progression of hallux valgus and associated pain.

Conclusions:

• Gait in individuals with hallux valgus is characterized by disrupted inter-segmental coordination.
• These findings highlight the importance of considering whole-foot kinematic strategies in the management of hallux valgus.
• Further research should explore the functional implications of these coordination changes.
