Locked Caster Locking and Unlocking Casters Directional Locking Casters Directional lock casters are indicated by a green sticker in the locking lever. To lock the directional locking casters, press the tab and align the caster with the frame. Once Aligned this locks the swivel of the casters and is beneficial for walking in a straight path or placing LiteGait® over a treadmill. Once the unit is positioned over a treadmill, all four caster brakes need to be locked Directional Locking Casters with Treadmill Position LiteGait® near the treadmill (or where you wish the patient to begin walking). Roll LiteGait® towards the front of the treadmill, until the casters line up parallel to the treadmill (or parallel to the path the patient will follow—a hallway for example). Press the directional locks to lock swivel of casters LiteGait® can now be easily rolled back and forth over the treadmill or on a straight path in the therapy room or hallway. NOTE: While locking the caster prevents rolling of the unit, it DOES NOT prevent the unit from sliding on a sloped, slippery floor. The unit should only be used on a flat floor away from stairs or ramps. NEVER leave a patient unattended in the unit. Total Locking Casters Total locking casters are indicated by a red sticker on the locking lever. To lock the total locking casters, press the tab until the brake snaps into place. The caster will lock the swivel of the caster and rotation of the wheel. Locking all four casters will make the device stationary. BRAKE NOTE: Your LiteGait® may look different than images above VI. Base and Casters LiteGait® is equipped with four casters. There are two total locking casters and two directional lock casters. Each leg has one type of casters, the total locking are mounted on the left leg the directional locking are mounted on the right leg. V.

VII. Harness Application The harness was designed to support a patient in an upright position, allowing for full hip extension. This upright posture plays a critical role in the effectiveness of the gait therapy performed with partial weight bearing. Harness Components The front of the harness wrap refers to the point at which the two ends of the harness meet. The harness can be worn with the closure either in the front or in the back. There are four buckles on the top and bottom of the harness wrap. The four top buckles extend beyond the harness from the top seam and attach to the LiteGait® overhead straps. The bottom four buckles attach to the groin piece and do not extend past the bottom seam of the harness. Preparing Harness for Application 1. Pick the appropriate harness (based on patient’s girth) and groin piece (based on patient’s anterior-posterior diameter) for the patient. 2. Adjust the groin strap buckles so there is symmetry in the straps-- equal strap length available on both ends of the padded groin piece and equal from side to side. 3. Attach the groin piece to the back of the harness. NOTE: The side of the groin piece with the H‐outline stitching (most padded) will go against the patient’s body. Front Overhead Straps Groin Pieces Girth Adjustment Estimating the Starting Size Half the Girth Test 1. Estimate the harness girth before placing on the patient by folding the unbuckled harness in half so that the ends meet. 2. Hold the folded harness in front of the patients torso to estimate the width from one side of the body to the other. 3. Tighten or loosen the three rows of side straps on each side of the harness to estimated girth. Symmetry Test 1. With the unbuckled harness folded in half, check the alignment of the top buckles (the ones that attach to the overhead straps of LiteGait). The buckles should line up / be adjacent to each other . If not adjacent , make small adjustment to side straps as needed to regain symmetry. Each side strap should be similarly lengthened to achieve symmetry.

2 3 1 Harness Application - While Standing 1. Wrap harness around patient with lowest side straps even with GREATER TROCHANTER. 2. Connect buckles top to bottom. 3. Adjust side straps* to the patient from bottom to top, alternate sides and tighten evenly. Be sure to maintain harness position at Greater Trochanter. * To Tighten, push slack of strap towards buckle, while pulling free end as shown. Do not tighten top buckles over rib cage. Quick Check  2 fingers should NOT fit between strap and body.  Bulges of tissue may be present between girth adjustment straps if adjusted appropriately. NOTE: A loose harness will ride up when overhead support is applied. This will cause discomfort in the groin region. A snug harness with no slack will grab the pelvic girdle and hold in place distributing weight evenly throughout harness wrap. Attaching Groin Pieces 1. Route the groin piece between legs to front. 2. Connect both buckles - one on each side. 3. Tighten the groin strap snugly so there is NO slack. To tighten, grab the groin strap or strap cover and: i. Pull out toward adductor surface of leg. ii. Pull up toward groin piece buckle. iii. Use other hand to pull down on excess strap on free end, then repeat on other leg. iv. Tighten back straps in the same fashion to remove all slack. Quick Check  Groin Piece should have NO Slack. Padding should be equal front and back. Padding should cover most of the inner leg with little or no exposed strap.  Pull on top buckles, if harness moves up torso, straps require additional adjustment. BACK FRONT ii iii i iv NOTE: A LOOSE GROIN PIECE DOES NOT IMPART GREATER COMFORT TO THE PATIENT, BUT ALLOWS THE HARNESS TO SLIDE UP THE TRUNK, PUTTING UNWANTED LOAD/FORCE ON THE GROIN AREA. TIGHTEN THE GROIN STRAP SO THAT NO SLACK REMAINS IN THE STRAPS. THIS ASSURES THAT THE HARNESS WILL NOT RIDE UP ON THE PATIENT.

CAUTION: SITTING WHILE IN THE LEG STRAPS WILL DISPLACE THE HIP AXIS OF LOCATION AWAY FROM AND OUT OF THE LEG STRAPS; REPOSITIONING OF THE LEG STRAPS WILL BE NECESSARY. Leg Strap Application 1. Wrap Velcro thigh cuff portion below bulk of thigh and above knee so strap does not interfere with knee function. 2. Strap should be perpendicular to ground and pointing up toward the hip on the outside of leg. 3. Connect male buckles on leg straps into plastic groin piece female buckles. 4. Tighten all three straps keeping center strap perpendicular to the ground and on the lateral surface of the leg. The bifurcation point on the strap (where the strap splits into two) needs to be at the hip joint axis of rotation to maintain symmetry. 5. Straps must be tightened completely, using a two-handed technique and getting rid of all slack, to properly anchor the harness in place and properly transfer the support to the thighs. Harness Application – In Supine 1. Roll patient away from you. 2. Attach groin piece and place harness on patient with half of the harness rolled and under patient. (Figure 1) 3. Hold harness in place with lowest strap at greater trochanter 4. Roll patient into supine. 5. Pull harness around. 6. Straighten harness. Reach behind patient to feel back buckle position. Check for symmetry. (Figure 2) 7. Connect front buckles 8. Tighten all 6 side straps with leg straight. (Figure 3) 9. Connect the groin piece to the front buckles and tighten as in previous section. (Figure 4) 10. Roll patient away from you 11. Tighten back straps of groin piece, removing all slack. (Figure 5) Quick Check  Harness should be equally spaced from side to side Figure 2 Figure 4 Figure 5 Figure 1 Figure 3

Connect the Harness to your LiteGait® 1. Lock all four casters to make the device stationary and adjust the yoke to the correct position, giving the patient approximately 5 to 6 inches of head clearance. 2. Extend the overhead straps until they are long enough to reach the metal buckles on the harness. Attach the four buckles that hang from the overhead straps to the appropriate buckles on the harness. Pull (shorten) the back straps until there is no slack. Leave a few inches of slack in the front straps. 3. Once the patient is connected, unlock casters. With one hand on LiteGait, press up button on hand switch to lift patient into a standing position. Roll LiteGait® forward slightly while lifting so patient ends up directly under the yoke buckles. If desired, have patient hold handlebars during sit to stand. If necessary, adjust height of the handlebars to suit the patient. 4. Re-adjust overhead straps to maximize postural support as necessary. To tighten (shorten) strap, gently lift up on the connected section of the strap and pull down on the loose end of the strap simultaneously. To lengthen strap, lift metal tab up and out and then pull down on strap. Repeat as necessary for all straps. 5. The unit can now be used for over ground therapy or to assist the patient in stepping up onto the treadmill. If Lifting is not Necessary With higher level patients who don’t need assistance to achieve standing, the harness may be connected to the LiteGait® with the patient standing on the floor or over the treadmill. 1. Lock all four casters to make the device stationary and adjust the yoke to the correct position, giving the patient approximately 5 to 6 inches of head clearance. 2. Extend the overhead straps until they are long enough to reach the metal buckles on the harness. Attach the four buckles that hang from the overhead straps to the appropriate buckles on the harness. Adjust all straps to maximize postural support as necessary. 3. If handlebars are desired, adjust height of the handlebars to suit the patient. 4. The unit can now be used for over ground therapy or to assist the patient in stepping up onto the treadmill if necessary. Stepping up onto Treadmill 1. Position LiteGait® unit at the end of the treadmill walking surface (if not already there) and lock both directional casters. 2. Standing beside the patient, slowly roll the unit forward toward the front of the treadmill while simultaneously pressing the up button on the hand switch. 3. While continuing to press the up button, assist the patient with stepping up onto the treadmill as needed. 4. Once the patient is standing on the treadmill, quickly re-tighten the overhead straps if necessary to increase the support provided by the unit, or use the lift mechanism to increase the overall support. In some cases it may be necessary to tighten all four overhead straps in order to decrease the distance between the patient’s head and the overhead support (to achieve the ideal 5 to 6 inches of head clearance). 4. Roll the unit to the front of the treadmill and lock the caster brakes. 5. Double check to see that the unit is locked into place and that the patient is in the center of the treadmill walking surface. 6. Adjust the handlebars to the appropriate height. CONTINUED ON PG 24

NOTE: THE CASTER BRAKES SHOULD BE LOCKED WHENEVER THE UNIT IS STATIONARY. RELEASE THE CASTER BRAKES ONLY FOR MOVEMENT OF THE UNIT. Over Ground Over Treadmill Over Ground Therapy Follow “Connect the Harness to your LiteGait® and Lift Patient” steps as noted in previous section. LiteGait® can be used over ground to perform gait training as well as to provide support for a variety of other activities such as balance training, therapeutic exercise, postural support for ADL, etc. Please refer to your booklet “Protocols for Partial Weight Bearing Gait and Balance Therapy” for more information, or email our clinical support department at [email protected]. Stepping up onto Treadmill (Continued) 7. To exit the unit, reverse the process. Keep directional casters locked until the LiteGait® is at the end of the treadmill. It is helpful to ensure that the locking casters are nudged into an outward rolling position so they do not get caught on the treadmill as they roll. 8. Keep in mind that some patients will need to sit directly into a chair at the end of their session even if they started the session in standing.

LiteGait® Maintenance Your LiteGait® has been specially designed to be durable and relatively maintenance free. The frame is constructed from high strength steel, and has been painted with a special powder coat to resist rust and scratches. Cleaning Harness The iHarness wrap is made with cloth material that is impermeable and wipeable. The iHarness and the overhead straps can be wiped with disinfection wash, per facility infection control procedures. Use of bleach is discouraged and may effect the permeability of the harness material. Laundering Harness All harnesses and groin straps, including the iHarness, can be washed in hot water up to 80°C according to facility infection control guidelines. Harnesses should be dried with low or no heat tumble dry. Use of bleach is discouraged and may effect the permeability of the harness material. Frequency FOLLOW FACILITY INFECTION CONTROL GUIDELINES. Cleaning Agent FOLLOW FACILITY INFECTION CONTROL GUIDELINES. Water Temperature WASH IN UP TO 176°F (80°C)* Drying Method Harnesses should be dried with LOW or NO HEAT TUMBLE DRY. Special Cleaning WIPED WITH DISINFECTION WASH, PER FACILITY INFECTION CONTROL PROCE- DURES * Water temperatures between 104°F and 176°F may cause wrinkling of the iHarness material. Harness Storage The harness has been made of a durable fabric to retain its shape and effectiveness through many uses and washings. However, it is imperative that the harness be stored properly to prevent damage to the buckles. When not in use, store the harness in a place or area that will prevent the harness from being stepped on or rolled over. The crushing downward force of a wheelchair or cart rolling over the harness would damage the buckles, making the harness ineffective and unsafe for further use. Cleaning Frame, Handle Bar Grips and Covers Table Frequency FOLLOW FACILITY INFECTION CONTROL GUIDELINES. Cleaning Agent FACILITY APPROVED CLEANING SOLUTION Drying Method WIPE DRY WITH CLEAN CLOTH Special Cleaning WD-40 CAN BE USED TO REMOVE DIRT OR OILY SPOTS.

1. Possible Cause: Resolution: The harness wrap and/or the groin piece are not tight enough. The harness and groin piece should be securely tightened from the start.* The har- ness wrap should be tight enough to grab on to the fatty tissue around the abdo- men. The groin piece should then be tightened securely to keep the harness from riding up on the patient and creating unwanted pressure in the groin area. A towel or a piece of foam can be wrapped around the patient’s abdomen for added pad- ding if needed. Symptom: Harness is riding up on the patient causing pressure in the groin piece area 1. Possible Cause: Resolution: Groin piece has slack, harness rides up making groin straps the only source of support The bottom two straps on the harness wrap must be tightened securely, the top one only if it rests below the rib cage. Applying the harness and groin piece loosely will cause them to slide upward.* Symptom: Frontal overhead straps are causing discomfort in the chest area of female patients. 1. Possible Cause: Resolution: The distance between the overhead straps places load on breasts. Use an extender to increase the front panel size and distance between the over- head straps possibly avoiding the chest tissue. Conversely, the harness wrap placed on the patient with opening in the back results in overhead straps getting closer to each other in the front. Symptom: The overhead straps slip off of patients shoulders 1. Possible Cause: Resolution: The overhead straps are too far apart. Place the harness wrap with the opening in the back. This will bring the overhead straps closer to each other. Symptom: The patient cannot stand to properly position and tighten the harness and groin piece. 1. Possible Cause: Resolution: Patient is too weak or unsafe to stand Apply the harness in supine position. Avoid harness application in sitting as it rein- forces flexed hip position. Symptom: BiSym Display Is Not Powering On 1. Possible Cause: Resolution: Battery is Not Connected to BiSym Display Connect Battery cable to BiSym Display 2. Possible Cause: Resolution: Low Battery Charge The Digital BiSym is powered by a separate battery located near the top of the LiteGait®. Charge the BiSym Battery following the Digital BiSym charging proce- dure. 3. Possible Cause: Resolution: Battery Needs to be Replaced Contact Service & Parts Department for replacement battery information. Symptom: BiSym Display is Not Reading Weight 1. Possible Cause: Resolution: Load Cell Cables are Not Connected On the left side of the scale there should be three cables, two that look like phone jack connectors and one that connects to the top of the LiteGait®. Confirm that the cables are securely attached to the BiSym display. NOTE: If load cells are connected properly and the BiSym continues not to read weight, contact Service & Parts Department for further information. Symptom: BiSym Display is Not Reading Zero When No Weight is on LiteGait. 1. Possible Cause: Resolution: Harness is Moving Slightly Any movement in the harness may cause some noise in the BiSym Scale reading. A reading near zero is a normal occurrence. 2. Possible Cause: Resolution: BiSym scale requires Zero Calibration Refer to Zero Calibration Instructions from BiSym section of manual. Symptom: BiSym Does Not Automatically Power Down. 1. Possible Cause: Resolution: Auto Shut OFF is set too long or set to ZERO Refer to the Change Settings from BiSym section of manual. 2. Possible Cause: Resolution: Issue with BiSym Contact Service & Parts Department for further troubleshooting instruction. Troubleshooting - Digital BiSym (Optional)
