The "price-tag" of foot health in infancy and early childhood: a cross sectional survey of UK parents.

Children's feet are complex structures and strategies for supporting good foot health throughout childhood can be challenging. Greater awareness of the contemporary factors influencing decisions, such as footwear purchases, is needed to inform health narratives which are more closely aligned to parents' attitude and behaviours. The aim of this study was to explore parent's knowledge of children's foot health, understand the common foot health concerns and experiences with footcare services. A purposeful sampling approach was used to recruit parents of children aged 5 years and under. Participants completed a self-administered, online survey which consisted of 39 questions across six sections: (1) Participant demographics; (2) Developmental events (milestones such as crawling and walking); (3) Foot health concerns; (4) Developmental aids (products such as baby bouncers and baby walkers); (5) Footwear; and (6) Foot health information. Both adaptive and mandatory questions were used. Descriptive statistics were used to summarise closed-ended questions, and a summative content analysis was adopted to draw inferences from the text data. Two-hundred thirty-nine parents completed the survey, and this represented female participants (n = 213) aged between the ages 34-42 (n = 126) or 25-34 (n = 83) years of age. The survey generated responses from a wide geographical spread across the UK, but the majority of these were from the North West of England (n = 75) and South East of England (n = 46). Four main themes were drawn from the content analysis: (1) foot health concerns and seeking advice; (2) information and advice; (3) how parents support infant milestone events; and (4) footwear.Conclusion: This work provides insight into parents' perspective on the broad topics of children's foot health, identifying common experiences and concerns about their children's foot health and the factors which influence decision making. Understanding more about these issues will help health professionals support parents during infancy and early years. What is Known: • Maintaining good foot health throughout childhood is important and many factors influence decision making. • There is little understanding about how parents care for their children feet and their understanding of good foot health practices and services. What is New: • Insight into the common factors which influence parents' approaches to supporting early development and the typical concerns that parents encountered about their children's overall foot health and footwear. • Identifies areas of children's foot health for health professionals to target when developing information sources for parents.

Steps towards evidence-based foot-care for children: Behaviour and opinions of health professionals.

Allied health professionals (AHPs) working with children need the appropriate knowledge, skills and experiences to provide high-quality care. This includes using research to drive improvements in care and ensuring that knowledge and practices are consistent and build upon the best available evidence. The aim of this work was to understand more about the shared behaviours and opinions of health professionals supporting children's foot health care; how they find information that is both relevant to their clinical practice as well as informing the advice they share. A qualitative design using semi-structured, one-to-one, telephone interviews with AHPs was adopted. Thematic analysis was used to generate meaning, identify patterns and develop themes from the data. Eight interviews were conducted with physiotherapists, podiatrists and orthotists. Five themes were identified relating to health professionals: (a) Engaging with research; (b) Power of experience; (c) Influence of children's footwear companies; (d). Dr Google - the new expert and (e) Referral pathways for children's foot care. The findings indicate that the AHPs adopted a number of strategies to develop and inform their own professional knowledge and clinical practice. There could be barriers to accessing information, particularly in areas where there is limited understanding or gaps in research. The availability of online foot health information was inconsistent and could impact on how AHPs were able to engage with parents during consultations.

Subject-specific finite element modelling of the human foot complex during walking: sensitivity analysis of material properties, boundary and loading conditions.

The objective of this study was to develop and validate a subject-specific framework for modelling the human foot. This was achieved by integrating medical image-based finite element modelling, individualised multi-body musculoskeletal modelling and 3D gait measurements. A 3D ankle-foot finite element model comprising all major foot structures was constructed based on MRI of one individual. A multi-body musculoskeletal model and 3D gait measurements for the same subject were used to define loading and boundary conditions. Sensitivity analyses were used to investigate the effects of key modelling parameters on model predictions. Prediction errors of average and peak plantar pressures were below 10% in all ten plantar regions at five key gait events with only one exception (lateral heel, in early stance, error of 14.44%). The sensitivity analyses results suggest that predictions of peak plantar pressures are moderately sensitive to material properties, ground reaction forces and muscle forces, and significantly sensitive to foot orientation. The maximum region-specific percentage change ratios (peak stress percentage change over parameter percentage change) were 1.935-2.258 for ground reaction forces, 1.528-2.727 for plantar flexor muscles and 4.84-11.37 for foot orientations. This strongly suggests that loading and boundary conditions need to be very carefully defined based on personalised measurement data.

The influence of gluteus maximus on transverse plane tibial rotation.

There is a common clinical belief that transverse plane tibial rotation is controlled by the rearfoot. Although distal structures may influence the motion of the tibia, transverse plane tibial rotation could be determined by the proximal hip musculature. Cadaver studies have identified gluteus maximus as having the largest capacity for external rotation of the hip. This study was therefore undertaken to investigate the effect of gluteus maximus on tibial motion. Kinematic data were collected from the foot and tibia along with EMG data from gluteus maximus for 17 male subjects during normal walking. A number of kinematic parameters were derived to characterise early stance phase. Gluteus maximus function was characterised using RMS EMG and EMG on/off times. No differences in muscle timing were found to be associated with any of the kinematic parameters. In addition, no differences in gluteal activation levels were found between groups of subjects who had different amounts of tibial rotation. However, there was a significant difference (p<0.001) in gluteus maximus activation when groups were defined by the time taken to decelerate the tibia (time to peak internal velocity). Specifically, subjects with greater gluteus maximus activity had a lower time to decelerate the tibia. We suggest that a high level of gluteus maximus activity results in a larger external torque being applied to the femur, which ultimately leads to a more rapid deceleration of the tibia.

Variation in pelvic morphology may prevent the identification of anterior pelvic tilt.

Pelvic tilt is often quantified using the angle between the horizontal and a line connecting the anterior superior iliac spine (ASIS) and the posterior superior iliac spine (PSIS). Although this angle is determined by the balance of muscular and ligamentous forces acting between the pelvis and adjacent segments, it could also be influenced by variations in pelvic morphology. The primary objective of this anatomical study was to establish how such variation may affect the ASIS-PSIS measure of pelvic tilt. In addition, we also investigated how variability in pelvic landmarks may influence measures of innominate rotational asymmetry and measures of pelvic height. Thirty cadaver pelves were used for the study. Each specimen was positioned in a fixed anatomical reference position and the angle between the ASIS and PSIS measured bilaterally. In addition, side-to-side differences in the height of the innominate bone were recorded. The study found a range of values for the ASIS-PSIS of 0-23 degrees, with a mean of 13 and standard deviation of 5 degrees. Asymmetry of pelvic landmarks resulted in side-to-side differences of up to 11 degrees in ASIS-PSIS tilt and 16 millimeters in innominate height. These results suggest that variations in pelvic morphology may significantly influence measures of pelvic tilt and innominate rotational asymmetry.

The status of gait assessment among physiotherapists in the United Kingdom.

OBJECTIVES: To evaluate how physiotherapists are trained in and use clinically orientated gait assessment tools and instrumented gait analysis, and to identify if a need exists for a standardized methodology. DESIGN: Survey. SETTING: UK National Health Service. PARTICIPANTS: Physiotherapists working with a variety of patient groups in 210 randomly selected Health Care Trusts. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Amount of gait assessment training, frequency of gait laboratory use, types and frequency of standardized gait assessment tools used, and expressed need for a gait assessment tool in clinical practice. RESULTS: A total of 1826 (43.5%) physiotherapists responded. Management of abnormal gait constituted a major aspect of physiotherapy practice; yet, there was no systematic use of standardized gait assessment tools. Gait video images were typically collected and analyzed without the use of standardized protocols. Only 23.1% of all respondents had a patient assessed in a gait laboratory. Clinicians indicated that they need training in gait assessment (66.4%) and desire guidance at a national level. Exactly 91.8% of physiotherapists requested a new gait assessment tool that can be used easily and quickly within a busy schedule without compromising reliability and validity. CONCLUSIONS: Gait assessment plays a pivotal role for physiotherapists managing gait problems. The challenge for developers of gait assessment tools is to find a balance between the practicalities of use and scientific merit.
