Knee proprioceptive function and physical performance of patients with patellofemoral pain: A matched case-control study.

Background: Patients with patellofemoral pain (PFP) present pain, functional limitation, and alteration in knee proprioception.

Purpose: To compare the knee joint position sense and lower extremity functionality between patients with PFP and controls. Secondarily, investigate the relationship between proprioceptive acuity and physical performance.

Association between movement patterns and risk of musculoskeletal injuries in navy cadets: A cohort study.

Objective: To investigate the association of movement patterns evaluated by the Dynamic Movement Assessment (DMA) with the occurrence of musculoskeletal injuries in navy cadets.

Design: Cohort study.

Setting: Participants were filmed performing the six functional tests of the DMA (deep squat, step up, single-leg squat, hop, plank and side-plank tests).

Soldier Load Carriage, Injuries, Rehabilitation and Physical Conditioning: An International Approach.

Soldiers are often required to carry heavy loads that can exceed 45 kg. The physiological costs and biomechanical responses to these loads, whilst varying with the contexts in which they are carried, have led to soldier injuries. These injuries can range from musculoskeletal injuries (e.

Trunk endurance, posterior chain flexibility, and previous history of musculoskeletal pain predict overuse low back and lower extremity injury: a prospective cohort study of 545 Navy Cadets.

Objective: To investigate predictors of low back and lower extremity musculoskeletal injury in a cohort of Naval cadets.

Design: Prospective Cohort Study METHODS: 545 Naval cadets (Males, n = 394, 72%) were followed-up over eight months. Nine variables were investigated as predictors: history of musculoskeletal symptoms in the last 12 months, ankle dorsiflexion range of motion, sit and reach test, isometric hip abduction and external rotation strength, alignment during the single leg squat test, single leg hop test for distance, prone plank and side plank tests.

Reliability and Validity of Frontal Plane Kinematics of the Trunk and Lower Extremity Measured With 2-Dimensional Cameras During Athletic Tasks: A Systematic Review With Meta-analysis.

Background: Two-dimensional (2-D) analysis is commonly used to quantify frontal plane kinematics of the trunk and lower extremity. However, there are conflicting results regarding the reliability and validity of these measurements.

Objective: To synthesize the current literature to determine whether 2-D analysis is a reliable and valid method of measuring frontal plane kinematics of the trunk and lower extremity during squatting, landing, and cutting tasks.

The development and validation of a custom built device for assessing frontal knee joint laxity.

Introduction: This study reports the development and validation of a quantitative technique of assessing frontal knee joint laxity through a custom built device named KLICP. The objectives of this study were to determine: (i) the intra- and inter-rater reliability and (ii) the validity of the device when compared to real time ultrasound.

Methods: Twenty-five participants had their frontal knee joint laxity assessed by the KLICP, by manual varus/valgus tests and by ultrasound.

The Effects of Injury Prevention Programs on the Biomechanics of Landing Tasks: A Systematic Review With Meta-analysis.

Background: Anterior cruciate ligament (ACL) tear is a common injury in sports and often occurs during landing from a jump.

Purpose: To synthesize the evidence on the effects of injury prevention programs (IPPs) on landing biomechanics as they relate to the ligament, quadriceps, trunk, and leg dominance theories associated with ACL injury risk.

Study Design: Meta-analysis.

Sedentary Occupation Workers Who Meet the Physical Activity Recommendations Have a Reduced Risk for Metabolic Syndrome: A Cross-Sectional Study.

Objective: We tested the hypothesis that sedentary occupation workers who meet the physical activity recommendations present a lower risk for metabolic syndrome (MetS) than their nonactive counterparts.

Methods: A cross-sectional study involving 502 sedentary occupation workers. Physical activity level was self-reported.

Combination of risk factors for metabolic syndrome in the military personnel of the Brazilian Navy.

Background: Cardiovascular diseases are the major cause of death in the population, and metabolic syndrome (MS) is a clinical condition significantly associated with the increase in morbidity and mortality.

Objective: To describe the pattern of combination of the risk factors related to the diagnosis of MS in the military personnel of the Brazilian Navy and to identify variables associated with the presence of MS in that population.

Methods: Cross-sectional study involving 1,383 men (18-62 years) assigned to military organizations in the city of Natal, state of Rio Grande do Norte.
