Hip and knee joints mechanics and asymmetries in individuals with a history of anterior cruciate ligament reconstruction during overground running.

Background: Individuals with a history of anterior cruciate ligament reconstruction (ACLR) represent altered knee joint mechanics in running. Hip joint can make subtle compensations in response to ACLR. Effects of ACLR on hip joint compensatory mechanisms is not well known.

The effect of time restricted visual sensory input on asymmetry of ground reaction force components in female children.

The association between visual sensory and the asymmetry index of sit-to-stand ground reaction force characteristics is not fully understood. Therefore, the purpose of this study was to investigate asymmetry index of sit-to-stand ground reaction forces, their times-to-peak, vertical loading rate, impulses, and free moment in blind and sighted children. 15 female children with congenital blindness and 30 healthy girls with no visual impairments volunteered to participate in this study.

Acute effect of foot orthoses on frequency domain of ground reaction forces in male children with flexible flatfeet during walking.

Background: Flatfoot is a structural and functional abnormality of the foot that may cause lower limb mechanical damage during walking. The aim of this study was to investigate the acute effect of foot orthoses on the frequency domain of ground reaction forces in children with flatfeet during the stance phase of walking.

Methods: Bilateral gait data were collected from fifteen male children suffering from flatfeet syndrome.

Do different methods for measuring joint moment asymmetry give the same results?

Gait asymmetry is defined as a loss of perfect agreement between the dominant and non-dominant lower limbs. Conflicting results from gait asymmetry studies may be due to different definitions of asymmetry, different research methods, and/or different variables and formulas used for asymmetry calculation. As a result, this makes it difficult to compare joint asymmetry values between studies.

Sit-to-stand ground reaction force characteristics in blind and sighted female children.

Background: The association between visual sensory and sit-to-stand ground reaction force characteristics is not clear. Impulse is the amount of force applied over a period of time. Also, free moment represents the vertical moment applied in the center of pressure (COP).
