Children that are diagnosed with Idiopathic Toe walking (cITW) are characterized by persistent toe-to-toe contacts. The objective of this study was to explore whether typical foot contact dynamics during walking predisposes cITW to a higher risk of falling. Twenty cITW and age-matched controls performed typical and toe walking trials. The gait parameters related to foot contact dynamics, vertical force impulses during stance, slip, and trip risk were compared for both groups. We found that cITW manifest less stable gait and produced significantly higher force impulses during push-off. Additionally, we found that cITW had a higher slip-initiation risk that was associated with higher foot contact horizontal and vertical velocities in addition to lower transitional acceleration of center of mass. We found that cITW exhibited a higher trip risk with toe clearance being significantly lower when compared to healthy counterparts. This study allowed for a quantitative description of foot contact dynamics and delineated typical from toe walking among cITW. Overall, the results indicate that cITW are less stable during typical walking and are prone to a higher risk of slip and trip-like falls.

Purpose The aim of the present study was to investigate the functional effects on gait parameters of serial ankle casts for patients with idiopathic toe walking (ITW), in comparison with an unremarkable control group. Methods A prospective trial with a pre-test–post-test control group design included ten patients with ITW and ten healthy matched children. Children with ITW underwent serial casting to stretch the plantar flexors, with two 14-day periods with walking plaster casts set at the maximum available ankle dorsiflexion. Both groups were assessed clinically and using a functional gait analysis before and after serial casting, as well as at a six-month follow-up visit. Results The normalized plantar heel force increased from 5% pre-interventionally to 79% at the follow-up. The upper ankle-joint angle and the base angle also demonstrated significant changes. Normalized compound action potentials of the medial heads of the gastrocnemius were reduced by 70%. None of these parameters demonstrated any significant differences at the follow-up examination in comparison with the healthy control group. Variations in the displacement of the knee joint on the sagittal plane and of the center of gravity in the transverse plane did not show any significant differences in comparison with the control group. Conclusion The reduction of muscle tone and lengthening of the ankle plantar flexors led to persistent increased active ankle dorsiflexion with significant long-term improvement of functional kinematic parameters. No significant difference in the gait analysis was found between the ITW group and healthy children six months after treatment. Level of Evidence Level II - Therapeutic

AbstractFalls are a multifactorial cause of injuries for older people. Subjects with osteoporosis are more vulnerable to falls. The focus of this study is to investigate the performance of the different machine learning models built on spatiotemporal gait parameters to predict falls particularly in subjects with osteoporosis. Spatiotemporal gait parameters and prospective registration of falls were obtained from a sample of 110 community dwelling older women with osteoporosis (age 74.3 ± 6.3) and 143 without osteoporosis (age 68.7 ± 6.8). We built four different models, Support Vector Machines, Neuronal Networks, Decision Trees, and Dynamic Bayesian Networks (DBN), for each specific set of parameters used, and compared them considering their accuracy, precision, recall and F-score to predict fall risk. The F-score value shows that DBN based models are more efficient to predict fall risk, and the best result obtained is when we use a DBN model using the experts’ variables with FSMC’s variables, mixed variables set, obtaining an accuracy of 80%, and recall of 73%. The results confirm the feasibility of computational methods to complement experts’ knowledge to predict risk of falling within a period of time as high as 12 months.

AbstractThis study investigates how the multisensory integration in body perception changes with increasing age, and whether it is associated with older adults’ risk of falling. For this, the rubber hand illusion (RHI) and rubber foot illusion (RFI) were used. Twenty-eight community-dwelling older adults and 25 university students were recruited. They viewed a rubber hand or foot that was stimulated in synchrony or asynchrony with their own hidden hand or foot. The illusion was assessed by using a questionnaire, and measuring the proprioceptive drift and latency. The Timed Up and Go Test was used to classify the older adults into lower and higher fall-risk groups. No difference was observed in the RHI between the younger and older adults. However, several differences were observed in the RFI. Specifically, the older adults with a lower fall-risk hardly experienced the illusion, whereas those with a higher fall-risk experienced it with a shorter latency and no weaker than the younger adults. These results suggest that in older adults, the mechanism of multisensory integration for constructing body perception can change depending on the stimulated body parts, and that the risk of falling is associated with multisensory integration.
