Leg Dominance Effect on Isokinetic Muscle Strength of Hip Joint
1Department of Biomechanics, Faculty of Physical Therapy, Cairo University, Giza, Egypt.
Objective:
The purpose of this study was to compare the isokinetic strength of hip muscles in dominant vs nondominant legs in healthy adults.
Methods:
Thirty-two healthy college students (15 male and 17 female) volunteered to participate in this study. A Biodex system 3 was used to measure isokinetic peak torque at an angular velocity of 60°/s for the hip flexors, extensors, abductors, and adductors in both dominant and nondominant legs. Hip flexors and extensors were tested from the supine lying position while hip abductors and adductors were tested from the side lying position using concentric mode of muscle contraction.
Results:
There were no statistically significant differences between the dominant and nondominant sides for all tested hip muscles.
Conclusion:
Leg dominance does not appear to affect hip muscle strength in healthy adults. This may be used as normative data for those with differences in muscle strength between involved and uninvolved sides.

01:23Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

03:05Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
