Rotation sequence and marker tracking method affects the humerothoracic kinematics of manual wheelchair propulsion

Anna C. Severin et al.

Summary: The literature on shoulder kinematics in manual wheelchair propulsion is growing, but inconsistencies in reporting rotation sequences and tracking methods make interpretation and comparison difficult. This study compared the effects of different rotation sequences and tracking methods on humerothoracic kinematics. The results emphasize the importance of reporting rotation sequences and tracking methods for straightforward interpretation and comparison.

Rotation sequence and marker tracking method affects the humerothoracic kinematics of manual wheelchair propulsion

Anna C. Severin et al.

Summary: This study compared the effects of three commonly used rotation sequences (ZXY, XZY, and YXY) and two tracking methods (anatomical and cluster) on the humerothoracic kinematics of manual wheelchair propulsion. The study found that different rotation sequences and tracking methods can have an impact on angle calculations and result interpretation.

Dynamic leg length measurement is a valid method for detecting anatomic leg length discrepancy

Sam Khamis

Summary: The study found that the dynamic leg length (DLL) measurement method can detect anatomic leg length differences, with differences primarily occurring between the maximal stance and minimal swing phases.
