To secure the dynamometer rotation position, tighten the knobin a clockwise CW direction and ensure that the dynamometer teeth are engaged. Use theDynamometer Rotation Scale, located on the base of the dynamometer directly beneath the yoke,to note the new position. It may also help to have a fixed location from which all subjects approach and leave the chair.

Be sure you fully comprehend the operating instructions, as well as the considerations, both physical and clinical, discussed throughout the manual before attempting to set up a subject for testing or exercise.

Practice setups and positioning with a healthy subject before attempting to set up an injured patient. These comments come from the clinical experience of our users as well as from published journals. However, because the Biodex System is so versatile and adaptable, you may find additional setups possible.

It is suggested that the clinician try the setups presented herein before attempting any setup improvisations especially for testing applica- tions. NOTE: Service should be provided by qualified personnel only. Please do not attempt installation or repairon your own. To tilt the dynamometer, supportthe dynamometer with one hand. You can now gently push or pull the dynamometer to the desired position. Tighten the knob firmly in a CW direction, and ensure that the dynamometer teeth are engaged,to secure the dynamometer in place.

Use the Dynamometer Tilt Scale located on the yoke to notethe new dynamometer tilt position. Loosenthe Dynamometer Height Handle by turning it CCW and simply apply hand pressure to the topor underside of the dynamometer to respectively raise or lower it. Retighten the handle to lock thedynamometer in position.

Use the Dynamometer Height Scale, located on the dynamometermounting post, to note the new dynamometer height. NOTE: The weight of the dynamometer is counterbalanced by a pneumatic assembly in the mounting post. When the locking handle is loosened, the dynamometer may tend to gently rise or fall, depending on the weight of attachments affixed to the dynamometer shaft.

After proper height is established, always secure the locking handle. Dynamometer Travel: The dynamometer Foot Pedals allow the dynamometer to move along thetravel in a horizontal plane left or right of the positioning chair. To move the dynamometer, pressdown on either foot pedal and slide the dynamometer to the desired location. Release the footpedal to lock the dynamometer in place.

To ensure stability, check that the dynamometer is fullylocked in a detent i. Use the Dynamometer Position Scale onthe travel to note position. Shaft Red Dot dynamometer shaft : The small red dot on the end of the dynamometer shaft provides an index for proper alignment of attachment and shaft during setup. When affixing any attachment to the dynamometer shaft, position the attachment so that its dot for the side to be exercised aligns with the dynamometer shaft red dot.

Failure to properly align the dots may result in a reduced range of motion. This function of the Rotate buttons has no effect on the range ofmotion limits previously established in Setup Mode. Press this button a second time to resume the test or exercisesession.

Depressing either the large red button atop the dynamometer or the hand-held remote button causes immediate cessa- tion of dynamometer shaft rotation. The principal purpose of this control is to guard against moving the subject into a portion of therange of motion that, for any reason, is contraindicated.

It should be noted that activating a com-fort stop after the onset of discomfort may result in a stoppage of movement while the subject isstill in the undesirable portion of the range.

With the shaft free, the operator should manually place the subject in a posi-tion such that the limb will not move in the direction of gravity. Educating the subject about the use of the Comfort Stops prior to exercise also serves to improveconfidence and motivation by reducing apprehension regarding the equipment.

Rotate the dynamometer to the blue color codepositions for right side testing or exercise. Patterns that use the same positioning for both sidesutilize the green color code areas.

Seat Rotation: The positioning chair offers degrees of rotation in the horizontal plane withdetente settings at degree intervals. To rotate the seat in either direction, turn the Seat RotationHandle toward the rear of the seat. The Seat Rotation Handle is located beneath the seat betweenthe forward receiving tube and forward buckle. While holding the Seat Rotation Handle, swivelthe seat to the desired position.

Release the handle to lock the seat in place, making sure the seatsets in the appropriate detente. Note the seat rotation position on the Seat Rotation Scale, locatedbeneath the seat on the seat post.

To move the chair along the travel, press down on either foot pedaland slide the chair to the desired location. Release the foot pedal to lock the chair in place. Toensure stability, check that the chair is fully locked in a detente. Use the Chair Position Scale, locat-ed on the travel, to note the new position.

Seatback Tilt: This adjustment allows the user to select any of five seatback angle settings: 85, 70,55, 40 and 25 degrees. To adjust the seatback tilt, pull up on one of the Seatback Tilt Handles, locat-ed on either side of the lower seatback frame. You may now adjust the seatback to the desiredangle. Release the handle and ensure that it locks into the selected detente. Record the new seat-back tilt angle from the Seatback Tilt Indicator, located at the bottom on either side of the seatbackframe.

Seat Height System 3 Pro Configuration only : The motorized seat may be automatically raisedor lowered over a range of 14 inches. To adjust the seat height, press the Up or Down Seat HeightPedals, located at the rear base of the chair. NOTE: The seat may be raised or lowered with the subject seated.
