“…These studies generally adopted angular displacement of segments in the comparison of scoliotic patients and healthy controls. However, previous studies dealing with gait asymmetry adopted segmental maximum and minimum peaks in each side [11,16,18]. Our study adopted a different calculation method from the one used in these previous studies since temporal information is also important in understanding human motor control in addition to force or angle in a certain time [20].…”

“…Such differences include decreased step length [6][7][8] and reduced range of motion (ROM) in the upper and lower extremities (LE) [6], but one study showed no difference [9]. It has also been reported that the gait pattern is symmetrical in healthy populations [10][11][12][13], but marked differences have been found between affected and unaffected limbs in pathological gait [14,15]. A limited number of studies have evaluated side-to-side asymmetry of gait in AIS.…”

“…In GRF studies conducted to evaluate gait asymmetry in AIS, patients with scoliosis showed asymmetrical gait in the vertical [17], anterior-posterior (A/P) [18], and medial-lateral (M/L) [19] directions. These studies adopted the peak angle of the joint [16] or the peak force [11,18] at a certain time to compute symmetry index. However, spatial-temporal information is an important factor to understand human gait control [20].…”

Asymmetrical gait in adolescents with idiopathic scoliosis

Purpose This study investigated side-to-side gait asymmetry in subjects with adolescent idiopathic scoliosis. Methods There were 20 adolescents with idiopathic scoliosis and 20 age-matched control subjects, who participated in the study. To minimize confounding effects, we recruited patients with similar spinal curvature for the scoliosis group, and all participants are right hand dominant. The participants were instructed to ambulate on a 10 m walkway while barefoot. There were two force plates in the middle of the walkway. The ground reaction force (GRF) and angular displacements of six segments (foot, shank, thigh, pelvis, trunk, and head) were measured during one gait cycle based on the right and left lower extremities. To remove the positional information in the kinematic data, the derivative of angular displacement in each segment was calculated. To evaluate the side-to-side gait symmetry, we calculated the cross-correlation of each bilateral gait parameter. Results In the kinematics, the scoliosis group demonstrated asymmetrical gait in the frontal and transverse planes compared to the control group. In the GRF data, the scoliosis group demonstrated asymmetrical gait in the medial-lateral (M/L) direction compared to the control group.Conclusions These results indicated that the scoliosis group produced an asymmetrical rotation pattern of the segments bilaterally in the frontal and transverse planes, resulting in asymmetrical GRF patterns in the M/L direction. This asymmetrical gait may be produced by changes in global postural control during gait and not simply by changes in control of only one or two specific segments.

“…Nevertheless, the results of our review must be interpreted with caution. First, several definitions for the term asymmetry exist in the literature [59][60]. We opted to define asymmetry as a statistically significant difference between the amputated and intact legs or comparing the amputated and referent joint segments of nondisabled controls based on similar previous systematic reviews [3][4].…”

Spinal, pelvic, and hip movement asymmetries in people with lower-limb amputation: Systematic review

et al. 2015

Abstract-Following amputation, people with transfemoral amputation (TFA) and transtibial amputation (TTA) adapt with asymmetrical movements in the spinal and lower-limb joints. The aim of this review is to describe the trunk, lumbopelvic, and hip joint movement asymmetries of the amputated limb of people with TFA and TTA during functional tasks as compared with the intact leg and/or referent leg of nondisabled controls. Electronic databases were searched from inception to February 2014. Studies with kinematic data comparing (1) amputated and intact leg and (2) amputated and referent leg of nondisabled controls were included (26 articles). Considerable heterogeneity in the studies precluded data pooling. During stance phase of walking in participants with TFA, there is moderate evidence for increased trunk lateral flexion toward the amputated limb as compared with the intact leg and increased anterior pelvic tilt as compared with nondisabled controls. None of the studies investigated spinal kinematics during other functional tasks such as running, ramp walking, stair climbing, or obstacle crossing in participants with TFA or TTA. Overall, persons with TFA adapt with trunk and pelvic movement asymmetries at the amputated limb to facilitate weight transfer during walking. Among participants with TTA, there is limited evidence of spinal and pelvic asymmetries during walking.

“…They are both well-known easy-to-use and accurate devices (Allard [2], Cavanagh [3], Herzog [4], Meyring [5], Perry [6], Perttunen [7], Viel [8]). In both case, the number of sensors can reach four per square centimetre, which gives a high spatial precision of the measurement.…”

-This article presents the development of a baropodometric device. The aim is to record foot-to-ground force during natural gait. The device consists of an instrumented shoe equipped with force sensors wired to a backpack laptop. The instrumentation should be light, efficient, easy to use for clinical staff and adapted to fit most patients' gait. Thus, we looked to optimize sensor location under the foot and sensor dimensions inside the sole. Numerical simulation and tensile tests lead us to conceive CuBe2 tubular-shaped sensors and specifically-shaped contact aluminum plates. We chose weight/efficiency optimal acquisition system. And we developed a whole treatment process and following graph visualization, optimized over time running and easiness of results reading. Then, we realized dynamic calibration and dead loads weighting to validate our conception. Finally, clinical testing is performed. The gait of the four healthy subjects is presented through the innovating graph visualization.
