The Reliability of Portable Fixed Dynamometry During Hip and Knee Strength Assessments

The reliability of portable fixed dynamometry during hip and knee strength assessments.

CONTEXT Insufficient lower extremity strength may be a risk factor for lower extremity injuries such as noncontact anterior cruciate ligament tears. Therefore, clinicians need reliable instruments to assess strength deficiencies. OBJECTIVE To assess the intrarater, interrater, intrasession, and intersession reliability of a portable fixed dynamometer in measuring the strength of the hip and k...

Relationship between Hip and Knee Strength and Knee Valgus Angle during Drop Jump in Elite Female Athletes

Purpose: The purpose of this study was to investigate the relationship between hip and knee strength with knee valgus angle during drop jump in elite female athletes. Methods: Forty female athletes (mean ± SD age, 21.5 ± 1.99 years height, 169.08 ± 8.25 cm body mass, 61.05 ± 10.06 kg) participated in this study. Isometric hip and knee muscles strength were evaluated using standard clinical...

Kinematics of Hip, Knee and Ankle During Cross- Slope Walking

Purpose: Little information is available on joint kinematic adaptations during walking on cross-slope surfaces (i.e. a surface incline perpendicular to the direction of locomotion). This study aimed to evaluate the effects of cross-slope surfaces on three-dimensional (3D) kinematics of hip, knee, and ankle joints during stance phase of walking.  Methods: This is a quasi-experimental study...

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

Isokinetic dynamometry of the knee extensors and flexors in

  Background :This paper explores the gender-related bilateral differences of extensor and flexor torques of the knee joint at low and high angular velocities in Iranian healthy males and females.   Methods : 70 healthy subjects (29 males (26.61±4.34 yrs and 41 females with average age of 23.07±3.70 yrs)) were participated in this study. Isokinetic peak torque values for knee extensors and flex...
