Abnormal patient data for the isostation b100.
The purpose of this study was to document the torque and range of motion parameters generated on the lsostation B100 by subacute low back pain patients 2-7 days postinjury. Abnormal values found in this study were compared to normal values found in a previous study. One hundred and forty-three males and 29 females were evaluated in a predetermined combination of three tests. These included: a) range of motion in each plane, b) repetitive flexion/extension, and c) a modified maximum lift. The results of the investigation indicate significant differences (p = 0.01) in parameters generated by the lsostation B100 between normals and abnormals in each test. Discrepancies between normals and abnormals were greater for females than males. Torque output was most significantly affected (p = 0.01) in the axis of flexion/extension for both males and females. Range of motion was most significantly affected (p = 0.01) in extension for both males and females. In test b (the flexion/extension repetitive test), the most significant (p = 0.01) percent reduction in torque and range of motion values occurred in the secondary axis of rotation and lateral flexion rather than flexion/extension. This reduced crossover activity, crosstalk, may be an indicator of guarded effort, poor effort or both. The lsostation B100 is a valuable tool as it provides objective information on torque output and range of motion for the low back.J Orthop Sports Phys Ther 1988;10(4):121-133.
