MyoStep Soft Exoskeleton
Target Users: Parents, caregivers, healthcare professionals, physical therapists, and pediatric specialists working with children who have cerebral palsy or motor impairments.
What is the MyoStep Soft Exoskeleton?
The MyoStep Soft Exoskeleton is an advanced pediatric mobility device designed to help children with cerebral palsy and other motor impairments walk more easily and safely. Unlike traditional rigid exoskeletons, MyoStep uses smart materials, artificial muscles, and flexible fabrics to provide lightweight, comfortable support that adapts to a child's movements.
This innovative device was developed through collaboration between the University of Houston BRAIN Center and TIRR Memorial Hermann. It represents a significant advancement in pediatric assistive technology by addressing common limitations of conventional mobility aids such as excessive weight, rigidity, and inability to accommodate growth.

How to Use: Step-by-Step User Guide
Before First Use
1Medical Assessment: Child must be evaluated by a pediatric physical medicine specialist or orthopedic surgeon to determine suitability for the device.
2Custom Fitting: Device should be professionally fitted by trained orthotist or therapist. Proper measurements include body dimensions, joint ranges of motion, and specific mobility limitations.
3Training Session: Parents, caregivers, and child should receive comprehensive training on device operation, donning and doffing procedures, and safety features.
Putting On the Device (Donning)
1Prepare the Child: Ensure child is wearing appropriate thin, comfortable clothing underneath. Check skin for any irritations, cuts, or pressure points.
2Position the Base: Place the child in a seated position. Start with the lower components and work upward, securing straps and buckles as instructed during training.
3Adjust for Comfort: Check all contact points for proper fit. The device should feel snug but not tight or restrictive. Ensure no bunching or pinching of fabric.
4Power On: Activate the device according to manufacturer instructions. Wait for system initialization and sensor calibration to complete.
5Test Movement: Allow child to stand and take a few steps while supervised. Observe for any discomfort, improper alignment, or device malfunction.
During Use
- Begin with short wearing periods of 30-60 minutes, gradually increasing as child adapts
- Supervise child closely during initial use periods
- Monitor skin condition every 15-20 minutes during first uses
- Watch for signs of device overheating or discomfort
- Allow child to communicate any unusual sensations or pain immediately
- Ensure adequate rest breaks between wearing sessions
Removing the Device (Doffing)
1Power Off: Deactivate the device completely before removing.
2Seat the Child: Have child sit in a comfortable, stable position.
3Release Straps: Unfasten all buckles and straps in reverse order of application.
4Gently Remove: Carefully slide device components off, supporting child's limbs as needed.
5Inspect Skin: Check all contact areas for redness, irritation, or pressure marks. Mild temporary redness is normal but should fade within 20-30 minutes.

Frequently Asked Questions
At what age can children start using the MyoStep?
The device is designed for pediatric use, typically for children around 3 years and older, depending on size and motor development. Individual assessment by a healthcare provider determines suitability.
How long should my child wear the device each day?
Start with 30-60 minutes and gradually increase based on tolerance and therapeutic goals. Your healthcare provider will establish a specific wearing schedule. Most children work up to several hours daily.
Can my child sleep in the device?
No. The MyoStep is designed for active use during waking hours. Remove the device during sleep unless specifically instructed otherwise by your physician.
Will the device hurt my child?
When properly fitted and used correctly, the device should not cause pain. Mild initial discomfort during adjustment period is normal, but persistent or severe pain indicates improper fit or use and requires professional evaluation.
How often does the device need adjustment as my child grows?
The MyoStep features adjustable components designed to accommodate growth. Regular follow-up appointments every 3-6 months are recommended, or sooner if device feels tight or child experiences growth spurts.
Is the device waterproof?
No. The MyoStep contains electronic components and should not be exposed to water. Remove before bathing, swimming, or water activities. Keep dry at all times.
What shoes should my child wear with the device?
Your orthotist will recommend appropriate footwear. Generally, well-fitting athletic shoes with good support and non-slip soles work well. Some modifications may be needed depending on device configuration.
Can my child play sports while wearing the device?
Discuss specific activities with your healthcare provider. Some low-impact activities may be appropriate, while high-contact sports may not be safe. The device supports walking and daily activities primarily.
How is the MyoStep different from traditional leg braces?
MyoStep uses smart materials and sensors to actively assist movement, is much lighter, adapts to natural motion patterns, and has a more discreet appearance resembling athletic clothing rather than medical equipment.
What happens if the battery dies during use?
The device has safety features to prevent sudden failure. Monitor battery levels regularly and charge as recommended. If power depletes, the device maintains structural support but active assistance ceases.
Will insurance cover this device?
Coverage varies by insurance provider and region. Work with your healthcare team and insurance coordinator to explore coverage options. The device may be covered as durable medical equipment or assistive technology.
