Context: Single- versus double-leg landing events occur the majority of the time in a netball match. Landings are involved in large proportions of netball noncontact knee injury events. Of all landing-induced anterior cruciate ligament injuries, most occur during single-leg landings. Knowledge of whether different single-leg functional performance tests capture the same or different aspects of lower-limb motor performance will therefore inform clinicians’ reasoning processes and assist in netball noncontact knee injury prevention screening. Objective: To determine the correlation between the triple hop for distance (THD), single hop for distance (SHD), and vertical hop (VH) for the right and left lower limbs in adult female netball players. Design: Cross-sectional. Setting: Local community netball club. Participants: A total of 23 players (age 28.7 [6.2] y; height 171.6 [7.0] cm; mass 68.2 [9.8] kg). Interventions: There were 3 measured trials (right and left) for THD, SHD, and VH, respectively. Main Outcome Measures: Mean hop distance (percentage of leg length [%LL]), Pearson intertest correlation (r), and coefficient of determination (r2). Results: Values (right and left; mean [SD]) were as follows: THD, 508.5 (71.8) %LL and 510.9 (56.7) %LL; SHD, 183.4 (24.6) %LL and 183.0 (21.5) %LL; and VH, 21.3 (5.2) %LL and 20.6 (5.0) %LL. All correlations were significant (P ≤ .05), r/r2 values (right and left) were THD–SHD, .91/.83 and .87/.76; THD–VH, .59/.35 and .51/.26; and SHD–VH, .50/.25 and .37/.17. A very large proportion of variance (76%–83%) was shared between the THD and SHD. A small proportion of variance was shared between the THD and VH (25%–35%) and SHD and VH (17%–25%). Conclusion: The THD and SHD capture highly similar aspects of lower-limb motor performance. In contrast, the VH captures aspects of lower-limb motor performance different to the THD or SHD. Either the THD or the SHD can be chosen for use within netball knee injury prevention screening protocols according to which is reasoned as most appropriate at a specific point in time. The VH, however, should be employed consistently alongside rather than in place of the THD or SHD.

Background: Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Although their potential in patients with knee osteoarthritis is vast, little research has examined their efficacy. Objectives: This study examines the effect of a proprioceptive knee brace on lower limb kinematics and kinetics in healthy participants and in participants with OA. Methods: Thirteen healthy participants were asked to perform a 10-cm step-down task with and without a proprioceptive brace. Data were collected using a 10-camera Qualisys system. Individuals with osteoarthritis completed the Knee injury and Osteoarthritis Outcome Score before and after 4 weeks of intervention. Results: During step-down reductions in knee maximum internal rotation, transverse range of movement, transverse plane angular velocity and maximum internal rotation angular velocity was seen. Ankle plantar flexion and inversion angular velocity decreased while inversion and maximum supination angular velocity increased. Improvements in Knee injury and Osteoarthritis Outcome Score were noted across all parameters with brace use. Conclusion: Positive changes in kinematic variables in multiple planes can be achieved with proprioceptive bracing alongside improved patient outcome. These changes occur at the knee but analysis of other weight bearing joints should not be overlooked in future studies. This study supports the concept of neuromuscular reinforcement and re-education through proprioceptive bracing and its application in the management in knee osteoarthritis. Clinical relevance Proprioception can alter symptoms and biomechanics embraced and adjacent lower limb joints. The results of this study highlights the potential uses of non-mechanical bracing in the treatment of osteoarthritis and other potential to bridge the osteoarthritis treatment gap. Furthermore, large-scale research is needed to match disease subset to brace type.

ObjectivesThe lower limb is widely reported as the most commonly injured body part in the field of hockey, more specifically lateral ankle sprains and internal knee injury. Despite this, there remains limited understanding of how the biomechanics of the sport could be adapted to minimise injury. The aim of this study was to propose a foot position during the hockey hit that results in the smallest joint angles and moments, from a total of four different foot positions: 0°, 30°, 60° and 90°, which may correlate to injury risk.MethodEighteen players from the local University Ladies Hockey Club participated in this study. Each player was required to perform a hit with their lead foot in four different positions: 0°, 30°, 60° and 90°, where 0° was a lead foot position perpendicular to the direction of motion of the ball. Angles and moments were calculated with the Vicon system using force plates and motion analysis.ResultsSignificant differences (p<0.05) were found between the angles and moments of the four foot positions tested, indicating that foot angle can influence the degree of angulation, and moments, produced in the lower limb joints during the hockey hit.ConclusionThere is a relationship between lead foot position and the angles and moments produced in the lower limb joints during the hockey hit, and this may correlate with injury risk.

Previous studies have reported certain sex differences in motor performance precision. The aim of the present study was to analyze sex differences in fine motor precision performance for both hands under different test conditions. Fine motor tasks were performed by 220 Spanish participants (ages: 12–95), tracing over the provided models – lines of 40 mm for both hands, two sensory conditions (PV—proprioceptive-visual; P—proprioceptive only) and three movement types (F—frontal, T—transversal, and S—sagittal). Differences in line length (the task focused on precision) were observed through MANOVA analysis for all test conditions, both sexes and different age groups. Sex differences in precision were observed in F and T movement types (statistically significance level and higher Cohens’ d were observed in condition with vision). No statistically significant differences were observed for both hands and sensory conditions in sagittal movement. Sex differences in fine motor precision were more frequently observed in the PV sensory condition in frontal movement and less in sagittal movement.

Body Adiposity

Diferenças sexuais no desempenho motor (DM) de crianças são atribuídas a fatores biológicos e ambientais. Entretanto, a significância relativa de um ou outro fator necessita de maior investigação. Neste estudo, procurou-se analisar a magnitude da influência do fator biológico adiposidade corporal (AC) sobre as diferenças sexuais no desempenho em tarefas motoras que envolvem o deslocamento de todo o corpo. Participaram do estudo crianças na faixa etária de sete a nove anos, sendo 36 de cada sexo e pertencentes à Escola de Aplicação da Faculdade de Educação da Universidade de São Paulo (EA-FEUSP). Foram coletadas as medidas de peso corporal (PC), estatura (EST) e dobras cutâneas medidas em oito locais. Posteriormente, calculou-se um índice de adiposidade subcutânea geral (ADG) através da somatória (mm) das dobras cutâneas mensuradas. Foram aplicados os testes de flexão e extensão dos braços em suspensão na barra fixa modificado (FEB) para membros superiores, e de salto em distância parado (SDP) para membros inferiores. O teste t de “Student” constatou diferenças entre os sexos na variável ADG, superior para o sexo feminino, e nas variáveis FEB e SDP, superior para o sexo masculino. As equações de regressão linear considerando a variável independente (ADG) e dependentes (FEB e SDP) foram comparadas entre os sexos através do teste de paralelismo entre retas de regressão e de interceptos no eixo Y. O resultado dessa análise indicou similaridade entre os sexos na relação entre ADG e os dois testes de DM. Concluiu-se que a AC foi inversamente relacionada ao DM. No entanto, essa variável biológica parece contribuir de modo pouco significativo para explicar as diferenças sexuais no DM de crianças em tarefas que envolvem o deslocamento do corpo todo

  Running gait cycle begins when one foot comes in contact with the ground and ends when the same foot contacts the ground again. In a running gait cycle each lower limb has a stance phase and a swing phase. During the stance phase eversion of the subtalar joint is one of the mechanisms used to absorb impact forces. However, excessive rearfoot eversion may contribute to overuse running injuries of the lower limb. It is necessary to provide additional insight on sex differences or differences between dominant and non-dominant limbs in the different phases of the running gait cycle, as well as in the movements of the subtalar joint in the coronal plane. Therefore, the aim of the current study was to determine bilateral asymmetries, sex differences and peak eversion angle in the running gait cycle of recreational runners. 20 recreational runners aged 20 – 28 years (10 males and 10 females) were recorded on a treadmill at a running speed between 11 km/h and 12 km/h with high speed camera at 300 Hz. Males and females showed no significant differences between limbs in any of the variables of interest, indicating no bilateral asymmetries in running gait cycle. Female runners demonstrated a greater time to peak eversion than male runners (36.92 ± 5.79% vs 26.37 ± 5.12%, p < .01) and this may be related to some overuse running injuries that are more prevalent in females. The data obtained in this study may serve as a useful reference for future research. Resumen. Un ciclo de carrera comienza cuando un pie contacta con el suelo y termina cuando el mismo pie contacta con el suelo de forma consecutiva. En un ciclo de carrera cada extremidad inferior tiene una fase de apoyo y una fase de vuelo. Durante la fase de apoyo la pronación de la articulación subastragalina es uno de los mecanismos para absorber las fuerzas de impacto. Sin embargo, una excesiva pronación puede predisponer a lesiones por sobreuso de la extremidad inferior. Son necesarias investigaciones adicionales sobre las diferencias por sexos y las asimetrías en las diferentes fases del ciclo de carrera, así como en los movimientos de la articulación subastragalina. Por tanto, el propósito del presente estudio fue determinar las asimetrías, las diferencias por sexos y la máxima pronación en un ciclo de carrera de corredores recreativos. 20 corredores recreativos de entre 20 y 28 años (10 hombres y 10 mujeres) fueron grabados corriendo en tapiz rodante entre 11 km/h y 12 km/h con una cámara de alta velocidad a 300 Hz. No existieron asimetrías en el ciclo de carrera pues no se encontraron diferencias significativas entre la pierna dominante y la no dominante en ninguna variable. La máxima pronación fue más tardía en mujeres que en hombres (36.92 ± 5.79% vs 26.37 ± 5.12%, p < .01), lo que puede estar relacionado con la mayor prevalencia de ciertas lesiones de la extremidad inferior en mujeres. Los resultados obtenidos en este estudio pueden servir de referencia para futuras investigaciones.
