...Jordan Skaro; Scott J. Hazelwood; Stephen M. Klisch Principal component analysis (PCA) has been used as a post-hoc method for reducing knee crosstalk errors during gait analysis. PCA minimizes correlations between flexion–extension (FE), abduction–adduction (AA), and internal–external rotation (IE...

To evaluate its efficacy, this study compared ankle joint kinematics and plantar pressures among the DAO, standard double upright ankle-foot orthosis (DUAFO), and a nonorthosis control (CON...

Similarly, affected-unaffected limb differences in cortical bone structure and bone formation rate in ambulatory mice show that stroke...
