A new performance test for cervical myelopathy: the triangle step test.

Study Design: Our original performance test for evaluating the severity of cervical myelopathy, the triangle step test (TST), was introduced along with an assessment of its validity.

Objective: The TST was designed to evaluate the lower extremity motor function objectively and quantitatively. This study aimed to assess the validity of the test by analyzing the relation to the other analytic methods.

Does the fists-on-clavicles position represent a functional standing position?

Study Design: Prospective analysis of sagittal vertical axis (SVA) on lateral spine radiographs using 3 different arm positions.

Objective: To examine whether fists-on-clavicles position represents a functional standing position.

Summary Of Background Data: Radiographic visualization of spinal and pelvic sagittal morphology is difficult during relaxed standing because of interference from the arms; however, standing with arms forward-flexed results in a negative shift in SVA.
