Background
Slipped Capital Femoral Epiphysis (SCFE) is femoral head slippage off the femoral neck through the physis occurring in children aged 8–16 years. Surgical intervention is required in all paediatric cases and there is no universal agreement on choice of surgical procedure.
Research question
What are the two-year 3D gait outcomes in children with SCFE who have undergone in-situ pinning (PIN) or modified Dunn procedure (MDP) compared with normative reference values?
Methods
17 children with SCFE who had undergone PIN (n=7, slip severity mild to moderate) or MDP (n=10, slip severity moderate to severe) surgical procedures prospectively underwent a 3D gait analysis post-surgery (2∙0 ± 0∙5 years). Ten age-matched children were also recruited to provide normative reference values. The conventional gait model was modified to incorporate Hara hip equations and Lerner pelvic tracking methods. Gait Profile Scores, Gait Variable Scores, kinematics, kinetics and spatiotemporal data were calculated for each group.
Results
Overall gait pattern, determined by the Gait Profile Score, indicated that both SCFE groups differed from the normative reference group (PIN 6∙6 ± 2∙5⁰, MDP 6∙2 ± 2∙0⁰ vs. 4∙0 ± 1∙3⁰ norm, p<0∙05). Normalised walking speed was reduced in the MDP group (0∙40 ± 0∙04) compared to the normative reference group (0∙46 ± 0∙06; p=0∙032).
Significance
Gait patterns of children with SCFE treated with PIN was more markedly altered than that of children with SCFE treated with MDP, despite having lower SCFE severity. Increased external hip rotation observed in the PIN group may be a pre-cursor for osteoarthritis in adulthood. Therefore the use of the corrective MDP which normalises hip rotation may be beneficial for reducing functional impairments.

There is a lot of research in terms of injuries and performance in football and nowadays aerobic capacity, spinal posture and mobility have been taken into consideration separately in terms of performance. Considering from a biomechanical perspective, we thought spinal curvature and mobility may affect aerobic performance and investigated the relationship between them.
Research question
Do young soccer players' segmental spinal curvature and mobility affect their aerobic capacity and maximal exercise performance?
Methods
Thirty-four young league players (mean age 16.56 ±1.11 years) were evaluated pre-season. Spinal assessments in the sagittal plane with a non-invasive, computer-assisted electromechanical device and aerobic capacity assessment with a cardiopulmonary exercise-testing device were applied. The relationship between spinal postural variables with aerobic capacity was done by Pearson correlation analysis, and simple linear regression analysis was used to estimate the effect of spinal curvature and mobility on aerobic performance.
Results
Various parameters of aerobic performance were related to spinal curvature and mobility. Maximal oxygen uptake (VO2max) and maximal heart rate (HRmax) were negatively correlated with thoracic angle (r=-0.343, p=0.047 and r=-0.344, p=0.046; respectively). Thoracic angle was also associated with tidal volume (VT) and VO2/HR (r=-0.347, p=0.044 and r=-0.348, p=0.044; respectively). Higher thoracic mobility caused to reach the anaerobic threshold (VAT) earlier (r=-0.368, p=0.032), at a lower speed (r=-0.367, p=0.033). In other segments, lumbar mobility was negatively correlated with VT at VAT (r=-0.346; p=0.045), while spinal inclination with HR at VAT (r=-0.387, p=0.024).
Significance
Although it is within physiological ranges, increased spinal curvature and mobility are associated with a decrease in aerobic capacity in young soccer players. Spinal curvature and mobility especially in the thoracic region may affect the aerobic performance of a soccer player. The trainers should consider spinal alignment for not only the technical and tactical but also the general performance of the soccer player.

Background
Some older adults benefit to a great degree from walking interventions and others experience little improvement. Understanding the personal characteristics associated with greater treatment response to different interventions could assist clinicians in providing patients with matched interventions to optimize both outcomes and resource use.
Research question
What personal characteristics are associated with improved gait speed for older adults participating in walking interventions?
Methods
This was a secondary analysis of 236 older adults from a trial comparing “Standard” (lower-extremity strength and walking endurance) to “Plus” (additional task-specific training for walking) interventions on gait speed in older adults (≥65 years). Predictors included sociodemographic characteristics, health status, physical performance, and self-reported function. We fitted linear regression models to 12-week change in gait speed.
Results
Predictors of improved gait speed in Standard group included: younger age (β=-0.015), lower BMI (β=-0.005), slower gait speed (β=-0.015), longer Figure 8 Walk time (β=0.010), and higher Late Life Function and Disability Instrument scores (β=0.003). The parsimonious set of multivariable predictors were never married (β=0.081), not a caregiver (β=0.208), no cancer history (β=-0.052), slower chair rise times (β=0.010), slower gait speed (β=-0.021), and better overall function and disability (β=0.006).
Predictors of improved gait speed in Plus group included: lower BMI (β=-0.004), farther Six-Minute Walk distance (β=0.014), and greater modified Gait Efficacy Scale (β=0.002). The parsimonious set of multivariable predictors were increased age (β=0.026), no cardiovascular disease (β=0.137), greater total physical activity counts per day (β=0.003), slower baseline gait speed (β=-0.072), and longer Six-Minute Walk distance (β=0.054).
Significance
Those with the combination of suboptimal physical performance and strong self-report of function may benefit from standard strength and conditioning. Individuals may best respond to task-specific training when health status and physical performance are suboptimal and not overtly compromised. Matching interventions with personal characteristics may enhance efficacy of treatments to improve walking in older adults.

Aim
To investigate whether a smartphone-based gait analysis tool can reliably output gait quality parameters that can be cross-analyzed to establish individual & disease-based changes in gait quality patterns.
Methods
A cross-sectional study made up of a 48-patients undergoing disability certification at the “Dr. José Castro Villagrana” or the “Dr. David Fragoso Lizalde” Health Centers in Mexico City, Mexico. Their sensorimotor performance was evaluated through an in-house smartphone/IMU based digital tool. Gait was analyzed by means of frequency analysis of the acceleration of the body mass measured at the sternum. A composite gait quality score was determined through principal component analysis based primarily on the explainability and uniformity of gait. Quality independence against demographic variables (age & weight) was tested through ANCOVA. The association between gait quality and gait parameters was analyzed by using multiple linear regression.
Results
A multiple regression model developed with a limited set of gait quality parameters successfully predicted gait smoothness with a 97.05 % accuracy with a mean square error of 0.085 between predicted and actual quality scores. The model demonstrates different predictive capacities across disease groups, with Osteoarthrosis + Osteoporosis having the highest R2 at 0.98 (p < 0.001) and Coxarthrosis having the lowest explained R2 at 0.79 (p < 0.001).
Conclusions
The assessment of gait quality, in family medicine, with low-cost digital tools is an area of opportunity yet to be explored. This tool can potentially disrupt the current disability workflow between primary and specialty care to have an objective method of assessing gait within a clinical consult. Individual patient-level benchmarking can give us insights into the patient's disease status, develop practical intervention strategies, and control the cost and quality of medical care by predicting an individualized course of disability or rehabilitation. Further studies are needed to validate digital gait assessments as clinical decision support tools for day-to-day clinical operations.
