Development And Validation

Physical surrogates and numerical models have been used to investigate the lower limb injury responses in blunt trauma related to occupant and pedestrian impacts during crash events. To date, automotive crash dummies used for studying the lower limb kinematics and injury responses in car crashes are designed to represent mid-age adults. But due to increase in fragility and frailty with age, the injury risk of the lower limb of elderly females is greater compared to younger adults. Thus, safety designs should expand for protecting elderly females in lower limb impacts. The current study focuses on developing a lower limb finite element model for elderly females with accurate anthropometry and anatomical details. The model was further validated against segmental and whole-body level experimental data of lower limb impact during pedestrian, frontal, and side impact loading. The validated model will be further integrated into the whole-body model to study injury mechanisms and safety designs for this vulnerable population of elderly females.

Posture, a potentially modifiable injury risk factor, is considered important in injury screening/prevention in athletes, yet few studies investigate relationships between posture and injury. This prospective cohort study investigated whether static posture is associated with lower limb injury risk in male football players (n = 263). Nine aspects of static standing posture (left and right rearfoot, knee interspace, lateral knee, lumbar lordosis, thoracic kyphosis, scoliosis S and C, forward head) were assessed from photographs during the pre-season using the modified Watson and Mac Donncha scale, which was dichotomised for analysis (deviated or normal). Player characteristics (age, height, mass, body mass index, competition level), match/training exposure, and previous and in-season non-contact lower limb injuries were recorded. Binary logistic regression investigated relationships between posture and injury (previous and in-season). Eighty previous and 24 in-season lower limb injuries were recorded. Previous injury was not associated with any postural variable. In-season injury was associated with previous injury (OR = 3.04, 95% CI 1.20–7.68, p = 0.02) and having a normal thoracic curve compared to kyphosis (OR = 0.38, 95% CI 0.15–1.00, p = 0.05) but no other postural variables. Static postural deviations observed in male football players in the pre-season are not typically associated with non-contact lower limb injury risk; thus, they are unlikely to add value to pre-season screening programs.

Intrinsic Foot Muscles

The human foot is a flexible structure characterized by a pronounced medial longitudinal arch (MLA) that compresses and recoils during running. That process is actively driven by the intrinsic foot muscles and requires a proper stability of the MLA. This introduces the concept of foot core stability. Because the intrinsic foot muscles are often neglected by clinicians and researchers, the purpose of this article is to provide some guidelines for incorporating foot core training in prevention or rehabilitation programmes for runners. The intrinsic foot muscles play a key role in postural control and maintain balance during single leg stance by controlling the height of the MLA and the foot pronation. During running, these muscles lengthen eccentrically during the absorption phase and subsequently shorten as the arch recoils during the propulsive phase, functioning in parallel to the plantar fascia. As a consequence, the dysfunction or weakness of the MLA active support may lead to injuries (e.g. plantar fasciopathy, Achilles or Tibialis posterior tendinopathy, metatarsalgia or medial tibial stress syndrome), due to numerous biomechanical cascades and mechanisms. In order to counteract or prevent these impairments, there are two ways for enhancing the foot core stability. Firstly in terms of volitional control of the intrinsic foot muscles, the “short foot exercise” must be practiced. Secondly strengthening sessions using neuromuscular electrical stimulation of these muscles seem to be a promising strategy in order to support the MLA and control the pronation during running. Practically, the foot core strengthening protocol may beneficiate not only the runners affected by excessive pronation related injuries but also those who sustained a long term lower limb injury and may be affected by a detraining process. In addition we warmly recommend integrating this protocol in any lower limb injury prevention programme or strength and conditioning plan for runners.
