CONTROL UNIT: Junction box mounted in the base for the battery power, handheld switch and contains electrical safety protection circuitry. The battery pack connects to this unit and is also located within a compartment of the actuator. HANDLEBARS: Unit has two adjustable handlebars. The handle bars are attached to the unit using two knobs.

About Your LiteGait® LiteGait® is comprised of several parts. YOKE: Y-shaped support that has four female buckles at the ends and is attached to the actuator with a flat plate secured by four bolts. OVERHEAD STRAPS: Four 44” long adjustable straps with male connectors at one end and padded female buckles at the opposite end. The male connectors attach to the yoke buckles and the female buckles attach to the harness providing postural support for the patient. HARNESS/GROIN PIECE: Adjustable wrap with a buckle closure in the front and three adjustable straps on each side. The four male connectors at the top of the harness that attach into the female buckles of the overhead straps. The four female buckles at the bottom of the harness allow for the connection of the groin piece. The H-shaped stitching on the groin piece denotes the top (or body side) of the piece. ACTUATOR: The mechanism that raises and lowers the yoke. The actuator consists of a concentric expanding and retracting square tower that houses the DC motors, gearing and the screw mechanism. It also provides the structural base to which the adjustable handlebars are attached.

NOTE: Over tightening the knobs may cause damage.

BASE: Two horizontal bars connected by two Ushaped tubes. The base moves freely over ground or can be locked into place during use over a treadmill. However, your unit must be locked into place at all other times. CASTERS: Four casters are attached to the base. The two casters on the left side are total locking and the two casters on the right are directional locking. Be certain to lock both caster brakes when using the unit over a treadmill or when connecting the patient to the unit. WARNING: NEVER leave patient unattended in the unit.

How to Adjust Yoke Height

FlexAble

The LiteGait® powered actuator column is raised and lowered by a hand switch with two up and two down arrows.

FlexAble allows for the rigid yoke to become position flexible, with up to 5 inches of travel. Thus, you can maintain the rigid yoke position or make it flexible giving the patient the option to experience more of their balance and weight bearing at their own discretion. Flexible Support Loosen the star knob on the bottom of the FlexAble. The amount of deflection can be varied by the amount the knob is loosened Rigid Support Tighten the star knob completely on the bottom of the FlexAble

Raising the Yoke Verify that LiteGait® has clearance above the yoke. Depress the button with the up arrow on the hand switch. Release the button when the yoke is at the desired height. Lowering the Yoke Verify that LiteGait® has clearance below the yoke. Depress the button with the down arrow on the hand switch. Release the button when the yoke lowers to the desired height.

NOTE: With the FlexAble or flexible, the LiteGait® yoke and harness still provide full support to the LiteGait® User.

Adjusting Handle Bars

Raised

Raising and Lowering the Handle Bar Loosen each knob in equal portions. The knobs should only need to be turned once to free the handle bars. Once the knobs are loosened slide the handle bars to the desired height. Hand tighten both knobs equally. The knobs should only need to be tightened one rotation.

Lowered

Emergency Lowering of Yoke If the down buttons fail to lower during normal use due to a low battery. There is an auxiliary down button that can be pressed to lower the device. Using a pen tip or small screwdriver, press the black emergency down button, this lowers one of the two columns of the LiteGait® when pressed. CAUTION: Using the Emergency Down Button may damage battery for future use. Use only in case of emergency. 15

Using Your LiteGait®

BiSym Scale (Optional) BiSym is a unique option available with LiteGait® to measure unilateral or bilateral support. LiteGait®’s special design includes a two-armed yoke which holds the patient above each shoulder. From these two points, the harness system can be adjusted to provide as much or as little support required to each side of the body. The range of support can vary on each side from full to no support. BiSym measures this asymmetric support at any given time during the gait cycle. Each arm of the yoke is instrumented with a load cell with electrical connections to a box at the base of the yoke. This electronic box powers the load cells, processes the signals and displays the supported loads of each arm or total support on a display unit. This can be used for charting of therapy progression as well as accommodation of weight bearing status. Optionally, digital outputs representing the supported loads on both sides of the body are provided for digital recording on to a PC. These signals vary as the weight bearing load changes from the right to left side during the gait cycle. This can be used as biofeedback for the patient. The more weight bearing by the patient = better posture = less work by machine = smaller BiSym reading. Connecting the BiSym Connect Corresponding Load Cell wires from BiSym ready LiteGait® yoke into BiSym Scale. Slide BiSym Scale onto the pre-installed bracket at the base of the yoke. NOTE: Proper installation will leave the monitor visible to the patient supported in the LiteGait® Using the BiSym Scale Press any button to turn the BiSym Scale on. The BiSym Scale has an AUTO SHUT-OFF that can be adjusting during the CHANGE SETTING? mode (see below) Changing Display Modes Press set to cycle through mode displays. Right Support Left Support Difference (Right - Left) Total (Right + Left) Both Supports

The top row displays the supported load in pounds (lb) or Kilogram (kg) depending on the setting. The bottom row displays a bar graph representing the value in the top row as a percentage of the specified weight (default value 100lb).

Using Your LiteGait®

Harness Application Preparation 1. Pick the appropriate harness and groin piece for the patient (based on patient girth). 2. Estimate the harness girth before placing on the patient by folding the harness in half so that the ends meet. Then, hold the harness in front of the torso to estimate the width from one side of the body to the other. 3. Tighten or loosen the 3 rows of side straps on each side of the harness. (To loosen the side straps lightly pull up on the black tabs on the side buckles.) 4. Keep the harness folded in half and align the top buckles so that they are adjacent with each other. 5. Take the groin piece and adjust the groin strap padding towards the center of the strap before putting it on. 6. Adjust the front groin straps so they are equal in length. 7. Adjust the back groin straps so they are equal in length. 8. Attach the groin piece to the back of the harness. 9. The side of the groin piece with the H-outline stitching (most padded) will go against the patient’s body.

How to put on the Harness 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. 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® straps. The bottom four buckles attach to the groin piece and do not extend past the bottom seam of the harness.

Harness Application – While Standing 1. Wrap the harness around the patient’s torso. 2. Place the lowest strap over the greater trochanter. 3. Attach the front buckles. 4. Tighten the lowest straps first 5. Attach the groin piece (see Groin piece attachment section). 6. Attach harness to LiteGait® (See Connect the Harness to your LiteGait® )

Using Your LiteGait®

Groin Piece Attachment 1. Attach the groin piece to the front harness buckles. The stitched side of the groin piece should be facing up against the body. 2. Hold the padded part of one end of the groin piece with one hand. 3. Pull it against the patient’s leg. Keep holding it while the other hand pulls the free end of the groin strap. 4. Tighten the groin strap snugly so there is NO slack. 5. Repeat on the other side. 6. Pull out any wrinkles or bunching from the patient’s clothing. 7. Sit the patient up or stand the patient, if safe NOTE: ENSURE AT ALL TIMES THAT THE BOTTOM STRAP OF THE HARNESS IS AT THE LEVEL OF THE GREATER TROCHANTER (HIP JOINT CREASE). NOTE: CONTRARY TO WHAT MAY SEEM REASONABLE, 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.

Connect the Harness to your LiteGait® 1. Lock the all four casters to make the device stationary. 2. Adjust the yoke to the correct position, giving the patient approximately 5 to 6 inches of head clearance 3. Extend the overhead straps until they are long enough to reach the upper connection on the harness. Attach the four buckles that hang from the overhead straps to the appropriate buckles on the harness. Pull the straps until taut. 4. With the patient in the harness , bring the patient into a standing position directly under the yoke buckles. Have the patient hold the handle bars. Adjust the height of the handle bars to suit the patient. 5. The unit can now be used for ground therapy , or to assist the patient in stepping onto the treadmill. 6. With higher level patients, the unit may be positioned over the treadmill prior to buckling the patient in place. WARNING: UNDER NO CIRCUMSTANCES SHOULD THE PATIENT HAVE ALL WEIGHT REMOVED FROM THE LEGS FOR MORE THAN TWO MINUTES AT A TIME

Leg Strap Instruction Leg Straps are abductor straps that replace the groin piece. They are sized to match either 1” plastic buckles as in WalkAble and Junior harness or 1.5” plastic buckles as in adult and small adult harness or the metal buckles of the bariatric harness. They consist of a pair of self-Velcro wraps with straps to connect to the harness. The wraps are applied below the bulk of the thigh and above the knee so as not to interfere with knee function but grab the upper leg tightly. The orientation of the wrap is such that the strap is perpendicular to the ground and pointing up toward the hip and is on the outside of the leg. Find the place where the strap splits into two. Place it right on the hip joint axis of rotation. The two straps departing from that spot should be pointing toward the buttonholes on the harness. The plastic female buckles that come out of the button holes (they normally receive the male buckles on the groin straps) are now plugged into the male buckles at the end of the leg strap. These straps are tightened while keeping the perpendicular strap centered between them. The strap that goes to the thigh wrap needs to be tightened to put preload the harness wrap. The harness will transfer the support from the LiteGait® Yoke through the side straps to the thigh wrap. Any slack in the straps (or as always a loose harness wrap) will be compensated by an upward shift of the whole harness until that slack is taken up. To prevent loss of harness position you must take up the slack and account for soft tissue give when tightening the side straps. 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. 21

Training with LiteGait® Over Treadmill 1. The yoke height should be adjusted so that the top is approximately 5 inches above the patient’s head when standing on the treadmill, so that the hardware hanging from the yoke is just out of the reach of patients head. 2. Lock the directional locks and position the unit over the treadmill. 3. Position the patient at the rear of the treadmill walking surface, facing the treadmill. The patient should either be seated in a wheelchair, on a chair, or standing with the help of an assistive device on the ground at the rear of the treadmill. 4. Roll the unit to the rear of the treadmill and lock the caster brakes. 5. The patient may hold onto the adjustable handlebar. Stand the patient up. For lower level patients, skip this step until the patient is connected to the LiteGait® unit. 6. Attach the four buckles on the overhead straps hanging from the yoke to the harness. (Be careful to attach the front straps to the front buckles and the back straps to the back buckles.) 7. Tighten each strap by gently lifting up on the connected section of the strap and pulling down on the loose end of the strap simultaneously. Repeat the procedure with all four straps, making sure that the straps are of equal length when finished. 8. Double check that all four straps have been connected to the appropriate buckles on the harness and all the straps have been tightened equally. 9. At this point, the patient should be securely buckled and attached to the unit. 10. For the seated patient, raise the yoke until the patient is in a standing position. Retighten each strap as necessary. 11. Standing beside the patient, slowly roll the unit forward toward the front of the treadmill. This position will allow you to both roll the unit and assist the patient with stepping forward onto the treadmill walking surface. 12. When the patient steps up on the treadmill, quickly re-tighten all four straps as necessary to increase the support provided by the unit. 13. Continue to roll the unit over the treadmill as far forward as possible, while the patient walks. 14. Once the unit is at the front of the treadmill, lock the caster brakes. 15. Double check to see that the unit is locked into place and that the patient is in the center of the treadmill walking surface. 16. Adjust the handlebar to the appropriate height. 17. To exit the unit, reverse the process.

Over Ground 1. Alternatively, lower the yoke so that it is approximately 5 inches above the patient’s head when sitting. 2. The patient should either be seated in a wheelchair, on a chair, or standing on the ground with the aid of an assistive device. 3. Position the unit over the patient. 4. Lock the caster brakes. 5. Loosen the straps and connect the appropriate straps to the harness being sure to connect the front straps with the front buckles and the back straps with the back straps. 6. Stand the patient up. (The patient may hold onto the adjustable handlebar.) 7. Tighten all four straps until the patient is standing in the proper upright posture. 8. Make any postural adjustments by tightening or loosening the appropriate strap. 9. Adjust the handlebar to the appropriate height. 10. As the patient begins to move over ground, several options are possible depending on treatment goals and the patient’s ability: 11. Push the unit matching the patient’s rate of walking. 12. Push the unit faster to increase the patient’s rate of walking. 13. Allow the patient to push the unit with or without assistance. 14. Allow the patient to walk forward, backward, or laterally. 15. Adjust the yoke height so that it is approximately 5 inches above the patient’s head when standing. NOTE: THE CASTER BRAKES SHOULD BE LOCKED WHENEVER THE UNIT IS STATIONARY. RELEASE THE CASTER BRAKES ONLY FOR MOVEMENT OF THE UNIT.
