“…The main curve angle of AIS adolescents in these two studies was right thoracic as in our study, and all AIS patients were similar in terms of the direction and area of the main and secondary curvature. Also, the results of our study are consistent with the findings of Pau et al (37) who showed that there were significant differences in COPr, COPv, and COPsa between only female AIS adolescents and healthy female adolescents and not male adolescents. A factor that may play a role in differences between genders is the level of physical activity and the strength of the trunk muscles (38).…”

Background: The aim of this study was to compare postural control between Adolescents with Idiopathic Scoliosis (AIS) and healthy adolescents. Methods: In this cross-sectional study, 20 AIS adolescents with a right thoracic curvature between 10 and 45 degrees and 20 healthy adolescents were matched to compare postural control. Postural control assessments included Center of Pressure (COP) range and COP velocity in the Anteroposterior (AP) and Mediolateral (ML) directions, and the COP sway area in the standing position with opened eyes and closed eyes by the force plate. Results: This study showed that the postural control variables in AIS adolescents and healthy adolescents in terms of COP range, COP velocity, and COP sway area in standing positions with open and closed eyes were significantly different with those of AIS adolescents being worse than those of healthy adolescents (all p<0.001). The interaction between Group and Condition (eyes open and eyes closed) was not significant for all variables (all p>0.05). Conclusion: Differences in the postural control measures indicate postural instability in adolescents with AIS compared to healthy adolescents.

“…Some limitations of the study should be acknowledged. Firstly, participation in sports activities was not considered as a factor in this study; sports activities may affect postural control (37,40). In this study, adolescents were not asked to stop sports activities.…”

“…Gait analysis was performed using a single wearable inertial sensor (G-Sensor ® , BTS Bioengineering, Italy), previously employed in studies of gait in children [35,36]. It was attached to the participant’s trunk (at L4-L5 vertebrae level) using a semi-elastic belt.…”

Abnormal excess or lack of body mass can influence gait patterns, but in some cases such differences are subtle and not easy to detect, even with quantitative techniques for movement analysis. In these situations, the study of trunk accelerations may represent an effective way to detecting gait anomalies in terms of symmetry through the calculation of Harmonic Ratio (HR), a parameter obtained by processing trunk accelerations in the frequency domain. In the present study we used this technique to assess the existence of differences in HR during gait in a cohort of 75 healthy children and early adolescents (aged 7–14 years) stratified into 3 equally-sized age and gender-matched groups (Underweight: UW; Normal Weight: NW; Overweight: OW). The accelerometric signal, acquired using a single wearable inertial sensor, was processed to calculate stride length, speed, cadence and HR in antero-posterior, vertical and medio-lateral directions. No differences in spatio-temporal parameters were found among groups, while the HR in the medio-lateral direction was found significantly lower in UW children, while OW exhibited the highest values. On the basis of the results obtained, HR appears capable of discriminating gait symmetry in children with different body mass even when conventional gait parameters are unchanged.

“…Instrumental gait analysis was performed using a commercially available, wearable inertial sensor (G-Sensor ® , BTS Bioengineering, Milan, MI, Italy), which was previously employed in similar studies involving children and adolescents [ 16 , 31 , 32 , 33 ]. The device was inserted into the pocket of a semi-elastic belt attached to the participant’s waist in such a way as to have it positioned approximately at the L4-L5 vertebrae level.…”

Smoothness of Gait in Overweight (But Not Obese) Children Aged 6–10

Excessive body mass represents a serious threat to the optimal psychophysical development of children, and it is known to be able to significantly affect their locomotor capabilities, making them more prone to the development of musculoskeletal disorders. However, despite the relevant number of existing studies, a clear gait pattern of overweight children has not been defined yet, particularly in the case of a mass excess that is relatively small (i.e., in those not obese). In the present study, we employed a wearable inertial measurement unit placed on the low back to derive spatio-temporal parameters and quantify the smoothness of gait (by means of harmonic ratio) from trunk accelerations acquired during gait trials carried out by 108 children aged 6–10 (46% males), stratified into two groups according to their body mass index (normal weight, n = 69 and overweight, n = 39). The results show that while gait speed, stride length, cadence and double support duration were found to be almost identical in the two groups, significant differences were observed in terms of harmonic ratio. In particular, overweight children exhibited a reduced harmonic ratio in the antero-posterior direction and higher harmonic ratio in the medio-lateral direction. While the significantly lower harmonic ratio in the antero-posterior direction is likely to be indicative of a loss of smoothness in the walking direction, probably due to a combination of factors associated with the altered movement biomechanics, the higher harmonic ratio in the medio-lateral direction might be associated with specific strategies adopted to increase lateral stability. Although further studies are necessary to elucidate the specific mechanisms that influence the smoothness of gait, it is noteworthy that harmonic ratios appear sensitive even to subtle change in locomotor control in overweight children characterized by apparently regular spatio-temporal parameters of gait and might be employed to assess the effectiveness of interventions designed to improve mobility functions.
