Effect of hip joint angle on concentric knee extension torque

Influence of Hip Joint Position on Muscle Activity during Prone Hip Extension with Knee Flexion

[Purpose] This study investigated the selective activation of the gluteus maximus during a prone hip extension with knee flexion exercise, with the hip joint in different positions. [Subjects] The subjects were 21 healthy, male volunteers. [Methods] Activities of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using sur...

The effect of hip joint position on knee joint isokinetic dynamometry indices in football and track and field athletes

The effect of knee valgus control feedback exercise on pain, hip torque and performance variables in participants with patellofemoral pain

 Aims and background: Patellofemoral pain syndrome (PFPS) is a common knee disorder frequently occurred in young females. Abnormalities of lower limb movement patterns during weight-bearing activities can directly affect referred pain. The purpose of this study was to determine the effect of knee valgus control feedback exercise on pain, eccentric hip muscle torque, performance and knee angle i...

Relationship between joint passive stiffness and hip lateral rotator concentric torque.

BACKGROUND Adequate passive stiffness of the hip joint can prevent the occurrence of excessive transverse plane lower limb movement during functional activities. Strength training of the hip lateral rotator muscles can be used to increase the stiffness of this joint. However, the relationship between hip joint passive stiffness and muscle strength remains undocumented in the literature. OBJEC...

Knee extension torque during repeated knee extension-flexion reversals and separated knee extension-flexion dyads.

I measured the knee extension torque, produced by eight hemiparetic patients during repeated knee extension-flexion reversals and during separated knee extension-flexion dyads, to determine the effect of "reversal of antagonists" on knee extension torque. The hemiparesis in these eight patients was secondary to intracranial lesions. I tested their involved lower extremity on an isokinetic dynam...
