False

Define cadence with respect to gait

In normal gait, at heel strike, the kinetics of the loading leg show the following external moments

An extension moment at the knee and a flexion moment at the hip

An adduction moment at the knee and a dorsiflexion moment at the ankle

A flexion moment at the knee and a plantarflexion moment at the ankle

An abduction moment at the knee and a plantarflexion moment at the ankle

In patients with unilateral hip OA, kinematic analysis of the affected hip in the sagittal plane has shown which of the following gait disturbances?

Increased dynamic range of motion with reversal of sagittal plane motion in midstance

Decreased dynamic range of motion with a reversal of sagittal plane motion in mid-swing

Decreased dynamic range of movement with a reversal of sagittal plane movement in mid-stance

Decreased dynamic range of motion with acceleration of extension in mid-swing

Kinematics studies of gait have shown that knee flexion at heel strike is.

Higher in healthy young individuals than in older indiviuals

The same for young healthy individuals and for older healthy individuals

Increases with age and severity of OA

Decreases with age and severity of OA

In patients with medial knee OA, kinetic studies have shown that over time there are changes in the relative moment contributions in the knee in which of the following ways?

Total moment decreases, adduction moment increases, flexion moment decreases

Total moment stays the same, adduction moment increases, flexion moment decreases

Total moment increases, adduction moment increases, flexion moment increases

Total moment stays the same, adduction moment decreases, flexion moment increases
