Background: Previous studies have demonstrated increased medial stresses in knee varus alignment. Selecting a suitable treatment strategy for individuals with knee malalignment should be a priority. Objectives: We aimed to investigate the effects of a 16-week corrective exercise continuum (CEC) program on 3-D joint angles of the dominant and non-dominant lower limbs in children with genu varus during walking. Methods: Overall, 28 male children with genu varus (age range 9–14 years) volunteered to participate in this study. They were randomly divided into 2 equal groups (experimental and control). The participants of the experimental group received CEC for 16 weeks. 3-D gait analysis involved using a Vicon Motion System. Paired and independent sample t-tests were used for within- and between-group comparisons, respectively. Results: For the experimental group, comparison of pre- and post-test joint kinematics of the dominant lower limb revealed that CEC decreased the peak ankle dorsiflexion angle by 26% (P = 0.020), peak foot internal rotation angle by 53% (P = 0.001), peak knee internal rotation angle by 40% (P = 0.011), peak hip abduction by 47% (P = 0.010), and peak hip external rotation angle by 60% (P = 0.001). In contrast, peak knee external rotation angle of the dominant limb was increased after the training program by 46% (P = 0.044). For the non-dominant lower limb, CEC decreased the peak ankle inversion by 63% (P < 0.01), peak ankle eversion by 91% (P < 0.01), peak foot internal rotation by 50% (P < 0.01), peak knee internal rotation by 29%; P = 0.042), peak hip abduction angle by 38% (P < 0.01), and peak hip external rotation angle by 60% (P < 0.01). Conclusions: CEC therapy reduced excessive foot and knee internal rotations as well as excessive hip external rotation during walking in children with genu varus.
Overall, CEC could decrease the possibility of injuries by a reduction in foot internal rotation, knee internal rotation, hip external rotation, and hip abduction of both lower limbs and an increase in dominant peak knee external rotation angle for children with genu varus during walking. Furthermore, the dominant and non-dominant lower limbs do not show similar responses to the same training protocol.
