Purposes: To detect the effects of hip joint position on the quadriceps recruitment pattern of
different resistance levels of rectus femoris (RF), vastus intermedius (VI), vastus lateralis …

Objective: To examine the relationship between knee extensor strength and quadriceps
muscle architecture evaluated with ultrasonography during relaxed and contracted …

The quadriceps femoris muscle (QF) is of clinical importance since it has been correlated
with pathologies at knee level, such as anterior cruciate ligament (ACL) injury, pain …

Background Until recently it has not been possible to isolate the mechanical behavior of
individual muscles during passive stretching. Muscle shear modulus (an index of muscle …

Objectives Orthopaedic surgery of the knee joint results in functional deterioration of the
quadriceps femoris muscle. However, little is known about quadriceps femoris muscle …

Background This study aimed to clarify the individual forces of each quadriceps head during
low-load contractions and to determine the associations between individual muscle force …

In the present study we investigated muscle contraction-driven changes in deep fascia
mechanical property, to reveal mechanical interactions between them. Fourteen males (22 …

Background Different strengthening exercises are generally prescribed to overcome the
undesirable effects of decreased muscular function on the osteoarthritic joint. Although a few …

Purpose The purpose of this study was to compare regional elastic properties between
anterior and posterior regions of the patellar tendon, and individual quadriceps muscles …

Background: More and more attention has been paid to the research of muscle mass and
muscle quality of quadriceps femoris (QF) in knee osteoarthritis (KOA). This study aimed to …
