Clinical Set-up for Postural Management
This webpage give details of the clinical set up of the Mygo seat. It is really important that the clinical setup of the product should only be completed by a technically and clinically competent person who has been trained in the use of the product. These settings are fundamental to the postural care of the child and if changes are made by someone other than the child’s therapist or a Leckey employee, the seat may no longer be set up in the best way for the child.
Leckey recommend a written record is maintained of all clinical setups for this product.
Set the backrest height, seat depth and footplate height before placing the child in the seat. These can be fine tuned when the child is in the seat.
Pelvic Harness (Size 1 or Size 2)
To adjust the depth of the pelvic harness, move the snap fastener to either position (B or C). Adjust the support straps to the required length. Ensure the buckle connects securely in the middle (D). If using the seat outdoors and your child is wearing a coat, position the pelvic harness under the coat.
Always attach the pelvic harness or Pelvic Cradle first before making any other adjustments.
Pelvic Cradle (Size 2 only)
The Pelvic Cradle should be flat and open when the user is placed into the Mygo Seating System. All four side and back buckles should be already attached to the seat. First fasten the buckle (A) at the front of the Pelvic Cradle. Then fasten the Velcro (B) at the sides to fit the Pelvic Cradle to the user. Then adjust the front and rear straps (C) and (D) to secure to position the user’s pelvis.
Always attach the pelvic harness or Pelvic Cradle first before making any other adjustments.
Hip Laterals (with Pelvic Cradle only)
To set the width of the hip guides loosen the Allen bolts (A), adjust to the desired width and retighten.
The backrest depth is adjusted by depressing the popper then sliding the back support tube to the desired position. This is very important as it will ensure the seat will fit the child, both when they are upright and in a recline position. There are three settings where the popper can be located. We recommend that you measure the child’s upper leg length to define the required seat depth (SD). To do this measure from the child’s lower back to the back of their knee. Then set the backrest to position A, B or C based on the table below.
Size 1 (SD)
Size 2 (SD)
This backrest depth should not be adjusted while the child is in the seating system.
The overall height of the backrest can be adjusted by loosening the two socket cap bolts, then positioning to the required shoulder height of the user. Once in position the socket cap bolts should be retightened securely. The height can be fine tuned when the user is in the seat.
Use caution when adjusting to minimum setting as fingers could become trapped between moving and static parts.
The backrest can be angled by loosening the bolt (A). Select the position you require then retighten the bolt securely. Always ensure the back angle is secure to maintain the desired posture for the child. The backrest angle can be adjusted with the child in the seat, but always support the backrest with one hand.
Always make sure the bolt is secure as this could cause injury to the child or carer.
There are two angle indicator strips on either side of the back adjuster. We have supplied angle location markers (shown below) on a card. These can be applied to the clear strip on the adjuster tube to indicate the desired positions for various activities such as rest, feeding, play. The angle indicator strip indicates the angle from the seat cushion to the backrest.
The black and yellow hazard strip on the inner tube indicates the maximum forward or prone position the backrest can be adjusted to.
Adjusting the dynamic backrest
To achieve the required amount of dynamic movement loosen the handle (a), slide to the required position and retighten securely. To return the backrest to a static position, loosen the handle (a), slide the backrest strut to the bottom, retighten the handle.
To angle adjust the backrest where a dynamic backrest has been fitted, you use the handle at the base of the backrest. Pull the locking pin (a) twist and unlock. Lift up the handle (b) and adjust the backrest. Pull the locking pin (c). Ensure that the locking pin in secure.
The range of the backrest angle nd the range if dynamic movement are a maximum of 30 ̊, i.e. if the backrest is upright, a full 30 ̊ is available on the dynamic system. If the backrest angle is at 10 ̊then only 20 ̊of movement is available with the dynamic backrest and so on.
Adjusting the upper leg supports
The upper leg supports will be set at the minimum position on arrival. Set the depth before placing the child in the seat. Fine adjustment is possible afterwards but is restricted by the user’s weight. To achieve the correct position measure the length from the child’s lower back to the back of their knee.
For Size 1 adjust the supports to the desired position using the locking lever (A) underneath the seat base. To adjust, press the locking button and release. Keep the supports pointing straight forward at this time unless wind sweeping or adduction, abduction must be accommodated, in which case set the angle accordingly using the
locking lever again. The supports can be readjusted once the child has been placed in the chair.
For Size 2, loosen the locking levers under the seat and slide leg support to required position. Keep the supports pointing straight forward at this time unless wind sweeping or adduction, abduction must be accommodated, in which case set the angle accordingly. Retighten bolt. To increase the angle further, remove bolt and move leg
angle to wider setting. Insert bolt into second slot (B) and tighten.
Upper leg guide lateral supports
To adjust the width of the knee supports on Size 1, loosen the bolts (A) on the underside of the leg support. Set to the desired width and retighten. To adjust the width or angle or angle on the lateral supports on Size 2, loosen the bolts (B) from above, move the guides and retighten the bolts.
To set the height of the footplate loosen the bolt (A) on the front of the calf support tube and slide the footplate to the required height and retighten the bolt. To set the correct height of the footplate measure the distance from the back of the child’s knee to the bottom of their heel.
You may have to adjust the angle to achieve the required foot position. To adjust the angle loosen the bolt (B) with the multi-tool, set to the desired angle and retighten. There is a safety popper to indicate maximum safe extension. This can be set with the child in the seat.
Always check the footplate is secure to prevent the user sliding forward and down in the seat which could pose a choking hazard if a chest or trunk harness is attached.
Footplate angle adjustment
To set the angle to accommodate plantarflexion or dorsiflexion, simply loosen or tighten the hand knob (A) to select the angle you require. The footplates can simply flip up to aid transfer.
Flexible sacral support
The flexible sacral support is used in conjunction with the pelvic positioning harness or Pelvic Cradle. To adjust the height, depth and angle, loosen the bolts on either side with the multi-tool provided. Adjust the support to the correct angle then retighten the bolts. The support will flex back and forward to assist the child into the preferred posture.
Always use caution to ensure fingers do not become trapped when adjusting the sacral support.
Loosen the socket cap (A) to adjust the width, height and angle of the lateral supports and retighten when you have achieved the desired position. To move flip away laterals, use knob B.
To change the width of the chest harness. Lift the front cover, adjust the Velcro straps to the desired width and replace the cover.
When the child is out of the seating system the trunk harness will be open but remain attached by two side clips (A) on one side and one pelvic harness clip (B). When placing the child in the seating system bring the trunk harness across the front and attach by connecting the clips into the buckles on the other side (C). Connect the remaining straps into the pelvic harness or Pelvic Cradle by feeding them through the loop (D) and snapping into place. Then connect the shoulder straps (E) into the clips at the top. If your child is wearing outdoor clothing,
the side straps can be opened by releasing the snap fasteners. The pelvic harness connecting strap can be released by moving the strap to the lower snap fastener position. All the connecting straps are adjustable by lifting the cover, adjusting to the desired length and replacing the cover.
Check the laterals and harnesses regularly to ensure they have not become loose as without appropriate trunk support the child may be at risk of slipping into a position they cannot recover from. This could present a choking hazard.
Adjusting the knee pads
The kneepads can be used as a limiter to help prevent the child from sliding forward in the seat. It can also be used above the knee to prevent the child from raising their foot. To adjust the knee pads lift the front cover adjust the Velcro straps to the desired length and reposition in place. To remove unclip the snap fastener on one side.
To position the sandals simply loosen the knob (A) under the footplate, select the position you require and re-fasten the knob. To position the user’s feet in the sandals secure the Velcro ankle and toe straps provided. If sandals are not required Velcro straps are provided for foot positioning.
Shoulder Support Laterals (Size 2 only)
To adjust the angle of the shoulder support laterals, loosen screw A, move laterals to required angle and retighten.
Contoured head support
To adjust the height, depth and angle of the contoured headrest, loosen the hand knobs (A) and when set to the desired position retighten the knobs. Do not remove the headrest while the user is in the seat.
Never use the headrest to force the position of the user’s head.
Always use caution to ensure fingers do not become trapped when adjusting the headrest.
Flat headrest with lateral supports
To adjust the height, depth and angle of the flat headrest, adjust using the hand levers (A), as shown on the contoured head support. To adjust the width of the laterals loosen plastic knob (B), slide to desired position and tighten securely.
To adjust the height of the armrest loosen the hand knob (B), set to the desired height and retighten. To adjust the angle, rotate ratchet handle (A) until the desired position has been achieved. To remove the armrest completely, loosen ratchet handle (C), press popper (D) and lift the armrest.
Always use caution as fingers could become trapped in the slot when adjusting the height.
The height and angle of the tray are set by adjusting the armrests as detailed above. To remove or adjust the depth of the tray loosen the knobs (A) under the armrest, set to the desired position and re-tighten securely.
Always use caution to ensure the child’s hands or arms do not become trapped when inserting the tray.
Never use the tray to steer or push the chair.
Do not place objects, hotter than 40 degrees Celsius on the tray.
Please note that the tray is for the use of the user only. Do not lean or place objects on the tray, greater than 8kgs (17.6lbs).
