    2. Operation Considerations for Safe Operation of the Multi-Joint Systems: 1. The clinician should always be present during testing or exercise sessions. Do not allow subjects to test or exercise by themselves. 2. Range limits should always be set after the subject is positioned according to protocol and before switching to a test or exercise mode.

  • Page 26 reached. In Passive mode, the dynamometer initiates motion when the <Start> button is pressed, requiring no active participation by the subject. Passive Mode Clinical Applications: 1. The Passive mode is frequently used post-operatively for the benefits of continuous passive motion, which assist with nourishment of the joint. 2.
  • Page 27 Isometric Mode – In this mode, the dynamometer maintains zero velocity at any selected point in the range of motion. Significant change in joint angle and overall muscle length does not occur. Isometric Mode Clinical Applications: 1. The Isometric mode may be used pre- or post-surgery with discretion. 2.
