1Installing RHEOLOGICInstallYou should have recevied an email with a link to an Össur website that includes yourlicense key for the software. Follow the instructions in the email to start the download andinstallation process.Note: If you install the program as an Administrator, make sure RHEOLOGIC is accessiblefor the user from the start menu or as a desktop icon.UninstallIn the start menu, locate the folder ‘Ossur’ containing RHEOLOGIC and select“Uninstall.”2Connecting to the RHEO KNEERHEOLOGIC uses Bluetooth to connect to the RHEO KNEE (Figure 1). Bluetooth is awireless connection that enables communication between your computer and the knee.Össur recommends that you use the Bluetooth already installed on your computer but ifyour computer does not come with Bluetooth capabilities you can order a Bluetooth USBdongle from Össur.Before you can connect to your RHEO KNEE you have to add it to your computeroperating system s list of Bluetooth Devices (see instructions that come with yourcomputer). Once you have done that, a COM port will be assigned to your RHEO KNEE.This COM port has to be provided when connecting to the knee.Figure 14
1. Once RHEOLOGIC has been started, click the „Connect“ button (Figure 2).Firgure 22. Select the COM port of your RHEO KNEE from the list of COM ports and click„Connect“ (Figure 3).Figure 3NOTE: To find the COM port assigned to your RHEO KNEE, open Bluetooth Devices,and identify your RHEO KNEE. Select “Properties” and look for the COM port number,e.g. COM port 9. If a distinction is made between outgoing and incoming ports, note theincoming port. If you have problems connecting, refer to the troubleshooting guide insection 5.3. RHEO KNEE is successfully connected when the Bluetooth indicator is blue andwhite and the status box changes from “Disconnected” to “Connected”.5
3RHEOLOGIC functionsIndicatorsIn the upper left corner, there is a battery indicator (Figure 4-1). The battery indicatordepicts the status of the RHEO KNEE’s battery. When the battery is critically low, the userwill receive a warning vibration and/or audio sound. In case of any disturbance to theconnection, due to timeouts in software, battery status, or excessive distance to the RHEOKNEE, the Bluetooth connection icon (Figure 4-2) will change color according to theconnection state.123465Figure 41. Battery level2. Bluetooth Connection3. Connect buttons4. Unit Name and Edit- Firmware Version- Step Count5. Message Board6. Warning SystemA message board (Figure 4-5) is located below the battery and Bluetooth indicators. Themessage board will show messages related to the status of the RHEO KNEE. Pay attentionif the message reads “Service required, please contact Össur representative”.If this message appears, RHEO KNEE has detected a problem, and the RHEO KNEEshould be sent for a service check.Change nameTo make it easier for you to recognize the RHEO KNEE among the list of accessibleBluetooth devices, you can customize the name of the RHEO KNEE to each specific user.Össur recommends that you keep the serial number as a part of the name for uniqueidentification (Figure 4-4).Warning systemThe RHEO KNEE provides audio and vibration warning systems, which alert the userthat power is low or a system malfunction has occurred (Figure 4-6). Select the type ofwarning: audio, vibration, or both. Sliding the frequency bar will change the pitch of theaudio warning (Figure 5).Important: Make sure that the user recognizes the warningsignals (some users are hearing impaired or have poor tactilesensitivity).Figure 56
CalibrationImportant: The RHEO KNEE should be calibrated before each new fitting, even when newfrom the box. Improper calibration affects the knee’s ability to perform optimally and maycompromise the user’s safety.1. Joint Angle2. Posterior Load3. Anterior Load123Figure 6To perform Calibration (Figure 6):1. Ensure there is NO LOAD on the knee. DO NOT connect the socket to the knee.2. Ensure the knee is FULLY extended.3. Press the “Calibrate” button. Calibration is complete when a sound/vibration signalcomes from the RHEO KNEE.Important: The following values on “Calibrate” are acceptable ranges for angle and load. Ifthe calibration values are out of the given ranges, calibration is required.Joint AnglePosterior LoadAnterior Load(0 to 3)(-2.5 to 2.5)(-2.5 to 2.5)7
Automatic adjustmentThe automatic adjustment enables the RHEO KNEE to learn and adjust to the unique gaitof each individual amputee (Figure 7). The on/off buttons are used to activate anddeactivate the auto adjustment feature of the RHEO KNEE. By activating the autoadjustment, all gait parameter settings are reset to default. Step-by-step instructions tothis process are detailed in the Automatic Adjustmenttab.1. ON Button2. OFF Button3. Step Counter312Figure 7Note: Auto adjustment affects stance flexion and swing flexion only.Note: If the auto adjustment mode is not manually disabled, it will automatically disableitself on the 200th step. The minimum number of steps is 60. For primary amputees, apersonalized gait setting is recommended, which should be updated as the gait improves.When the primary amputee is able to walk 60–90 steps, the auto adjustment procedureshould be performed.Manual adjustmentsImportant: When making adjustments, make sure that the user is in a stable standingposition or seated. All RHEO KNEE functions (including stance phase stability) will beinterrupted during the period in which the settings are updating.The Manual Adjustments tab contain five settings to adjust gait parameters – and onefeature that allows for keeping the knee locked in extension (Figure 8).8
Stance flexionStance flexion (level ground) depicts the prosthetic limb in stance phase moving into kneeflexion. This adjustment is the primary mechanism of providing additional knee stabilityto the user when walking on level ground. It also allows for the user to walk using a stanceflexion ambulation pattern. Adjustment varies from 0–100. The default value is 50.11. Slider2. Arrows3. Value4. Checkbox4321432Figure 8Stance flexion (stairs and ramps) depicts a set of stairs and ramp. This setting will allowfor independent resistance to be established for ramp and stair walking. Adjustmentvaries from 0 – 100. The default value is 50.Increasing the stance flexion resistance allows for a faster increase in stance support forthe user. On level ground, the stance flexion rate may be slower and will require increasedloading to initiate. On stair/ramp descent, the user will descend more slowly and withgreater support. Decreasing the stance flexion resistance allows for slower increase instance support for the user. On level ground, this means that the stance flexion rate maybe more rapid and will require decreased load to initiate. On stair/ramp descent, the userwill descend more rapidly and with less support.The RHEO KNEE requires one step to transition between level ground walking resistanceand stair/ramp resistance. The RHEO KNEE stance control settings may be customized tomaximize security or terrain recognition depending on the user’s preference.Optimal stability: The level ground value is increased to match the stair/ramp value.Recommended when stability is critical on all walking surfaces and stance flexionambulation pattern is not being utilized. The user will experience a high degree of stanceresistance on all walking surfaces, including the first step of terrain transition.Variable stance resistance: When the level ground value is less than the stair/ramp value,easier stance flexion walking is possible. A greater difference in resistance will be noticedduring the first step of terrain transition. Ensure alignment through knee center or 5mmposterior to knee center.9
Important: Foot alignment is critical. Posterior foot position may lead to difficulties instance release. Anterior foot position may lead to toe stubbing when walking in stanceflexion.Stance extensionStance extension depicts the prosthetic limb in stance phase and moving in to extension.This adjustment controls how rapidly the resistance increases with knee extension rate.The adjustment is required only when the user is walking in a stance flexion ambulationpattern and assists in providing proper timing of stance flexion/extension reciprocationand enhanced comfort. The default value is 30. Increasing the stance extension resistanceallows for more rapid increase in resistance to knee extension and slower knee extensionrate when load is placed on the prosthesis.Flexion target angleThe flexion target angle depicts the prosthetic limb at its maximum knee flexion angleduring the swing phase. Adjustment of target angle varies from 45–80 . The default valueis 60 .Increasing the flexion target angle allows for increased heel rise and delays kneeextension. Decreasing the flexion target angle allows for decreased heel rise and promotesmore rapid knee extension.Important: For most individuals, the flexion target angle should remain at the defaultsetting, 60 degrees. When manually adjusting the flexion target angle, make smallchanges one or two degrees at a time.Swing extensionSwing extension (level ground) depicts the prosthetic knee moving into extension duringthe swing phase on a level walking surface. Adjustment varies from 0–100. The defaultvalue is 20. Swing extension (ramps and steps) depicts swing extension resistance forstair/ramp walking. Resistance activates after one step onto the step/ramp.This adjustment is minimized and set to zero so that rapid extension may occur on rampsand stairs for increased security. Adjustment varies from 0 – 100. The default value is 0.Increasing the extension resistance slows the extension rate towards the end of swingphase. Decreasing the extension resistance increases the extension rate towards the endof swing phase.Terminal swing (TS)Terminal swing is the last phase of swing extension prior to full knee extension. Theterminal swing adjustment feature in RHEO KNEE is divided into two interlinkedparameter settings:Terminal swing resistance (TSR) controls the velocity of the terminal swing. Increasing theTSR values increases the resistance. Decreasing the TSR values decreases the resistance.The default value is 20.10
Terminal swing point (TSP) controls the rate of the terminal swing. Increasing the TSPvalues delays the resistance onset. Decreasing the TSP values hastens the resistanceonset. The default value is 20.Note: The terminal swing parameter settings should only be utilized when the swingextension parameter has been optimized to the user's gait.Extension holdThis setting is active when the box next to “Extension Hold” is checked. The setting isuseful for vehicle entry/exit, especially in low-rise vehicles. When active, the user maykick the knee into extension by using rapid hip flexion followed by hip extension. A lockthen activates to prevent the knee from flexing against the force of gravity. The user is notforced to hold the shin in extension while entering the vehicle. After 3 seconds, the shinautomatically unlocks and moves into flexion with gravityManaging usersThe User Manager can be accessed from "Database" in the file menu.
