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.
