Association of spinal deformity and pelvic tilt with gait asymmetry in adolescent idiopathic scoliosis patients: Investigation of ground reaction force

Does Vertical Ground Reaction Force of the Hip, Knee, and Ankle Joints Change in Patients with Adolescent Idiopathic Scoliosis after Spinal Fusion?

“…In this study, we observed that vGRF was lowest during the heel strike phase, with increasing trend noted during the early stance and mid stance phases and a decreasing trend up to the baseline. The asymmetrical pattern of vGRF was observed across all groups; similar findings were also reported recently by Park et al [ 12 ]. Nearly symmetrical patterns of vGRF were observed when COP of the body shifted to the left and right during the walking phases.…”

“…Reflective tracking markers were attached to the subjects' right and left iliac crests, anterior superior iliac spines, greater trochanters, hips and medial and lateral knees, medial and lateral ankles, heels, and 2nd and 5th metatarsal heads [ 11 ]. Then, the subjects were asked to walk as naturally as possible, following the walking speed recommended in a previous study that also involved a similar study population[ 12 ]. The captured motion images were used to define the orientations of the body segments and the force exerted on the force plate during the gait analysis using computer software (Qualisys Track Manager, visual 3D; Qualisys, Gothenburg, Sweden).…”

Comparison of Pedobarographic Profile in Young Males with Left and Right Scoliotic Posture

“…There are no differences in any observed foot pressure or force parameter between left and right scoliotic posture group in this study, suggesting that scoliotic posture is not associated with those parameters. These findings are consistent with studies from this field that assessed asymmetries in force components of GRF (Giakas et al, 1996;Chockalingam et al, 2004;Yang et al, 2013;Park et al, 2016b).…”

“…These movement compensations can balance asymmetries caused by scoliosis. This might be the reason why differences between scoliotic and non-scoliotic individuals are seen in EMG (Mahaudens et al, 2009;Mahaudens and Mousny, 2010), kinematic (Chen et al, 1998;Engsberg et al, 2001;Kramers-de Quervain et al, 2004;Mahaudens et al, 2009;Mahaudens and Mousny, 2010;Syczewska et al, 2010;Syczewska et al, 2012;Yang et al, 2013;Park et al, 2016a), spatio-temporal (Chen et al, 1998;Lenke et al, 2001;Engsberg et al, 2001;Mahaudens et al, 2009;Syczewska et al, 2010;Park et al, 2016a) and some components of kinetic parameters (Giakas et al, 1996;Chockalingam et al, 2004;Chockalingam et al, 2008;Bruyneel et al, 2009;Chern et al, 2014;Yang et al, 2014;Park et al, 2016b), but not in force components of ground reaction forces (Giakas et al, 1996;Chockalingam et al, 2004;Yang et al, 2013;Park et al, 2016b).…”

“…Research based on ground reaction forces (GRF) appear to have more consistent findings. Most of the studies suggest that there is association between scoliosis and GRF parameters, especially in right and left foot asymmetry (Chockalingam et al, 2004;Chockalingam et al, 2008;Bruyneel et al, 2009;Chern et al, 2014;Yang et al, 2014;Park et al, 2016b). Another interesting finding is that GRF parameters tend to have larger variability in scoliotic patients compared to non-scoliotic individuals (Giakas et al, 1996;Chockalingam et al, 2008).…”
