Abstract:
ObjectiveTo evaluate and analyze the characteristics of lower limb muscle activity and plantar pressure in females with the in-toeing gait using International Classification of Functioning, Disability and Health (ICF) and biomechanical methods. MethodsA total of 60 young females were recruited from September 2021 to May 2022, out of whom 30 females with in-toeing gait were as experimental group, and 30 females with normal gait were as control group. The motor function of lower extremities was coded by ICF, and the surface EMG signals and plantar pressure characteristics of lower limbs (rectus femoris, biceps femoris, gastrocnemius and tibialis anterior) were measured by wireless surface EMG tester and insole plantar pressure system. ResultsThe integral electromyography (iEMG) and muscle contribution rate of tibialis anterior were higher (|t| > 2.000, P < 0.05), and the iEMG and muscle contribution rate of rectus femoris were lower (|t| > 2.233, P < 0.05) in the experimental group than in the control group. The contact area of the 2nd to the 5th metatarsal bone, heel lateral and total foot areas (t > 2.879, P < 0.01), the peak force of the 1st metatarsal bone, mid foot and heel lateral areas (t > 2.720, P < 0.01), the peak pressure of the 1st to the 5th metatarsal bone and heel lateral areas (t > 2.079, P < 0.05), and the impulse of the 1st and the 4th metatarsal bone, and heel lateral areas (t > 2.310, P < 0.05) were significantly higher, while the impulse of heel medial area was lower (t = -3.024, P = 0.002) in the experimental group than in the control group. ConclusionIn the process of natural walking, the muscle activity of the in-toeing gait in young female is dominated by tibialis anterior and rectus femoris, the contact area of heel lateral area is larger, the peak pressure, pressure, and impulse are higher, and the impulse of heel medial area is lower.
