ABSTRACT Study design: A cross-sectional non-experimental study. Objectives: To collectively detect the reliability and feasibility of the five types of clinical tests that have been used to measure endurance of the trunk muscles in subjects with and without low back pain (LBP) and identifY the sensitivity of each test to predict the probability of the occurrence ofLBP. Background: Testing spi...
MINI: The authors wanted to determine which existing primary-care low back pain stratification schema is associated with distinct subpopulations. Initial stratification by DMPP identified potentially distinct epidemiological groups. DMPP stratification resulted in discrimination beyond that provided by disability or chronicity risk stratification alone. STUDY DESIGN A cross-sectional study of...
Stiffness is an index for determination of elastic properties of body and its optimum range is different in various motion patterns. The Spring-mass model is used for calculating stiffness. In this method, the whole leg is modeled with a linear simple spring. The aim of this study is determination of lower body stiffness and evaluation of its correlation with agility, as dominant motion patt...
The objective of this study was to determine and compare leg asymmetry between preferred dominant non-dominant legs in muscular power balance among sub-elite soccer (football) players Qatar. Thirty-two professional local from the Qatar Stars League (Second Division) participated (23.1 ± 6.1 years). They were classified according their (preferred kick ball). Twenty-two had a right leg, remaining...
Introduction: The aim of the current study was to measure ground reaction force and center of pressure (COP) during lower extremity perturbation in single leg standing whit knee flexion and extension in healthy subjects, in addition to revealing reliability of the device used for the related perturbation for using another studies, reliability is one of the characteristic of measuring instrumen...
This study investigated bilateral and unilateral asymmetries of strength and flexibility in male young professional soccer players. Thirty-six soccer players (age: 18.9 ± 1.4 years) participated in this study. A Biodex Isokinetic Dynamometer was used to assess the hamstring and quadriceps strength at selected speeds of 60°/s, 180°/s and 300°/s. Hip joint flexibility was measured using a goniome...
[Purpose] To clarify the characteristics of fluctuations in the center of gravity (CoG) of badminton players by comparing them between those with high and low performance levels. [Subjects] Eight male badminton players belonging to teams ranked among the top 3 at the All Japan Badminton Championships (high-level group) and 8 playing badminton for recreation in university clubs (low-level group)...
Objective: Stiffness is a characteristic of viscoelastic structures and is an effective factor in sports movement biomechanics, which is an important factor in motion production and neuromechanical control of human body. The purpose of this study is to determine the relationship between lower extremity stiffness and selected biomechanical variables during vertical jumps. Methods: 20 male physi...
This longitudinal study of 27 infants examined the development of pulling-to-stand (PTS). In general, infants began PTS using a two-leg strategy and transitioned to a half-kneel strategy. As a group, infants showed no preference for either strategy at the onset of PTS, switching between strategies until half-kneeling became the dominant pattern about 1 month after the onset of PTS. Examination ...
