Kinematic and Neuromuscular Measures of Intensity During Drop Jumps in Female Volleyball Players

Frontiers in Psychology, 2021
The aim of this study was to assess drop jump (DJ) performance variables (jump height, contact time, and reactive strength index) concomitant to surface electromyography (sEMG) of lower limb muscles during DJs from different drop heights (intensities ...

Knee and Hip Joint Kinematics Predict Quadriceps and Hamstrings Neuromuscular Activation Patterns in Drop Jump Landings. [PDF]

PLoS ONE, 2016
PURPOSE:The purpose was to assess if variation in sagittal plane landing kinematics is associated with variation in neuromuscular activation patterns of the quadriceps-hamstrings muscle groups during drop vertical jumps (DVJ).

Evaluation of quantitative muscle MRI and an intelligent phenotyping housing system as advanced phenotyping methods in a mouse model of calpain 3‐deficient muscular dystrophy

Animal Models and Experimental Medicine, EarlyView.
We applied quantitative MRI of the lower limb and automated home‐cage phenotyping to a mouse model of calpainopathy to detect early disease changes. At 15 months, calpain 3‐deficient mice showed increased water T2 values correlating with immune cell infiltration in the soleus and gastrocnemius muscles, while assessment of motor activity revealed only ...

The Vastus Medialis Insertion Is More Proximal and Medial in Patients With Patellar Instability: A Magnetic Resonance Imaging Case-Control Study

Orthopaedic Journal of Sports Medicine, 2019
Background: The anatomy and function of the quadriceps muscle play a role in patellofemoral stability. Few studies have evaluated anatomic differences in the vastus medialis between patients with and without patellar instability.

Trochleoplasty Is Associated With High Rates of Patellofemoral Arthritis: A Systematic Review

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To identify 2‐ to 5‐ and >10‐year complications of trochleoplasty and define rates of postoperative patellofemoral arthritis. Methods PubMed, Embase, and Web of Science were queried for terms related to trochleoplasty. Included studies were clinical studies using trochleoplasty to manage patellofemoral instability and were published in English ...

Medial Patellofemoral Ligament Reconstruction Using Double Limbed Rectus Femoris Autograft

Arthroscopy Techniques, EarlyView.
Abstract Medial patellofemoral ligament reconstruction is routinely performed when conservative treatment fails and patients present with recurrent patellar dislocations. Most described techniques require fixation or some type of bony procedure on the patella.

EMG profile in two different angles during maximum voluntary isometric contraction in squat exercise [PDF]

Motricidade, 2011
The aim of the present study was to analyze the electric activity of the vastus medialis (VM) and vastus lateralis (VL) in two differing angles (70° and 90° of knee flexion) during maximum voluntary contraction in squat exercise.

Single‐Stage Repair of Complex Anterolateral Radial and Posterior Root Tears of the Lateral Meniscus, With a Concomitant Multiligament Knee Reconstruction of the Anterior Cruciate Ligament, Medial Collateral Ligament, Posterior Oblique Ligament, and Anterolateral Ligament in a Young Athlete

Arthroscopy Techniques, EarlyView.
Abstract Early meniscal repair and anatomic reconstruction in a multiligament knee injury optimizes outcomes and restores tibiofemoral mechanics. This technique describes a lateral meniscus posterior root and radial tear repair, with concomitant medial ramp repair, performed during single‐stage reconstruction of the anterior cruciate ligament ...
