FOREWORD

OptiFlex® 3 Continuous Passive Motion (CPM) Therapy Unit

This manual has been written for the operators of the OptiFlex 3 Continuous Passive Motion (CPM) Therapy Unit. It contains general instructions for operation, precautionary instructions, and maintenance recommendations. In order to obtain maximum life and efficiency from your OptiFlex 3 CPM Unit, and to assist in the proper operation of the unit, read and understand this manual thoroughly. The specifications put forth in this manual were in effect at the time of the publication. However, owing to Chattanooga Group’s policy of continuous improvement, changes to these specifications may be made at any time without obligation on the part of Chattanooga Group. Before administering any treatment to a patient, you should become acquainted with the operating procedures, as well as the indications, contraindications, warnings, and precautions.

Product Description Continuous Passive Motion is a postoperative procedure designed to aid in patient recovery after joint surgery. This unit is typically used postoperatively for total knee replacement and Anterior Cruciate Ligament (ACL) repairs. After extensive joint surgery, if a patient fails to move the joint, tissue around the joint will become stiff and scar tissue will form, resulting in a joint with limited range of motion. By repeatedly flexing and extending the affected joint through a prescribed arc of motion for an extended period of time, the OptiFlex 3 CPM Unit lessens the adverse effects of immobilization and trauma on the knee joint.

PENDANT FUNCTIONS AND USE Start/Stop (Emergency Stop): Starts or stops the treatment. How to Use: Press the Start/Stop (Emergency Stop) button to begin or end the treatment.

CHART 1 COMFORT ZONE

NOTE: When unit is stopped and the Start/Stop (Emergency Stop) button is pressed, the unit will immediately begin moving in the opposite direction of the last movement.

C = Comfort Zone activated temporary flexion limit established.

Comfort Zone™: Temporarily decreases the flexion ROM when discomfort is experienced during treatment. How to Use: Press and the carriage will immediately reverse direction to move toward the extension angle. For the next five cycles, the carriage will operate in a range 5° less than the angle where the button was pressed. The Comfort Zone Flexion Angle is 5° less than the angle where the button was pressed. Once five cycles are complete, the Comfort Zone Flexion Angle will be increased by 1° each consecutive cycle until it reaches the currently Programmed Flexion Angle. See Chart 1. NOTE: If Comfort Zone is pressed within 30° of the currently Programmed Extension Angle, treatment will stop and the message "Comfort Zone Too Small" will be displayed.

5° = 5° less than the angle where Comfort Zone was activated. Upon completion of five cycles, ROM will increase by 1° each cycle until it reaches P. P = Programmed Flexion angle. S = Start/Finish.

• If pain is severe, do not use the Comfort Zone function. Stop treatment immediately. Failure to stop treatment could result in tissue damage and could compromise the surgical repair.

Fast Back™: When the carriage reaches 15° less than the Programmed Flexion Angle, it will begin to slow down. The deceleration rate will be half of the Programmed Speed when the carriage comes within 10° of the flexion angle. Upon reaching the flexion angle, the carriage will reverse direction and resume the Programmed Speed as it moves towards the extension angle. See Chart 2.

F = Programmed Flexion Angle E = Programmed Extension Angle

How to Use: While pressing and holding the Mode button, press the Fast Back button to enable the Fast Back mode. NOTE: If both Fast Back and Oscillation Zone modes are enabled, the carriage will move at the slower of 75°/ min. and half of the Programmed Speed while in the Oscillation Zone ROM.

PENDANT FUNCTIONS AND USE Progressive ROM™: When Progressive ROM is activated, the unit will automatically increase the Programmed Flexion Angle by 1° every hour, up to a maximum of 5° per 24 hour period. See Chart 4. How to Use: Press and hold the Mode button. Press the Progressive ROM button to enable the Progressive ROM mode. Set the desired Final Flexion Angle by pressing and holding the Flexion Button while using the Up and Down Arrows. Accept the Final Flexion Angle by pressing the Mode Button. NOTE: The unit must run for a full hour at the entire ROM before the flexion angle will be increased. Decreasing the flexion angle will automatically deactivate this mode.

Oscillation Zone™: When the carriage reaches the Programmed Flexion Angle, it will oscillate between the Programmed Flexion Angle and 10° less than the flexion angle, three times. The 10° range of motion is known as the Oscillation Zone ROM. While in the Oscillation Zone ROM, the carriage will move at 75°/min. or the Programmed Speed, whichever is slower. On the third oscillation cycle, the carriage will hold at the flexion angle for the Programmed Extension/Flexion Delay Time. See Chart 3. How to Use: While pressing and holding the Mode button, press the Oscillation Zone button to enable the Oscillation Zone mode. NOTE: If both Fast Back™ and Oscillation Zone modes are enabled, the carriage will move at the slower of 75°/ min. and half of the Programmed Speed while in the Oscillation Zone ROM.

NOMENCLATURE

OptiFlex® 3 Continuous Passive Motion (CPM) Therapy Unit

PENDANT FUNCTIONS AND USE Independent Delay Time You can set independent Delay times for extension and flexion. If an extension and or flexion delay time is required, simply hold down the Delay button and the Extension or Flexion button and use the Up or Down Arrows to adjust the time.

Force Reversal Force Reversal is a programmed setting that will automatically reverse the direction of the leg orthosis if the device detects a greater amount of resistance than what is programmed. Force Reversal allows you to set the amount of force required to passively move the joint without causing unnecessary pain or damage to the surgery.

Selectable Scrolling The scrolling feature is disabled at the factory. Should you desire to enable this feature, simply press and hold the Delay and Mode buttons. The display will scroll patient data for two cycles then return to displaying Current Carriage Angle.

The Force Reversal feature has 10 sensitivity settings, with a minimum setting of 1. NOTE: The maximum setting of 10 is the factory default and functions as carriage obstruction.

Patient Lock-Out The Patient Lock-Out feature prevents the patient from changing any parameter except Comfort Zone™ and Start/Stop (Emergency Stop).

To change the Force Reversal sensitivity setting, press and hold the Speed and Extension/Flexion Delay buttons simultaneously and use the down arrow to decrease the sensitivity setting.

To enable the Patient Lock-Out feature: Press and hold the Up Arrow and the Mode button for three seconds. A single short beep will confirm that the feature has been activated. Repeating the above sequence will deactivate the feature. A single short beep will confirm that the feature has been deactivated. Language Selection To select display language, press and hold the Mode and Extension buttons simultaneously for 3 seconds. Use and arrows to select desired language and then press Mode to accept.
