A novel approach for the detection and exploration of joint coupling patterns in the lower limb kinetic chain.

Background: A comprehensive perspective on foot and lower limb joint coupling is lacking since previous studies did not consider the multi-articular nature of the foot and lower limb neither accounted for biomechanical heterogeneity.

Research Question: The current manuscript describes a novel methodological process for detection and exploration of joint coupling patterns in the lower limb kinetic chain.

Methods: The first stage of the methodological process encompasses the measurement of 3D joint kinematics of the foot and lower limb kinetic chain during dynamic activities.

Are two-dimensional measured frontal plane angles related to three-dimensional measured kinematic profiles during running?

Objectives: To investigate the temporal relationship between two-dimensional measured frontal plane joint angles and three-dimensional measured kinematic profiles during the stance phase of running, and to assess the intra- and intertester reliability of the two-dimensional angles.

Design: Observational study.

Setting: Research laboratory.
