Orthoses, Splints, and Standing Programs in Duchenne
Orthoses, night splints, and standing programs help manage contractures and posture in Duchenne. What each does, when they are used, and how they fit into care.
Orthoses, splints, and standing programs are pieces of equipment and routines used to keep joints mobile, support posture, and slow the tightening of muscles in Duchenne muscular dystrophy. They work alongside physiotherapy rather than replacing it, and they become more important as muscles weaken and the risk of contractures rises. Used consistently, they help preserve comfort, position, and function.
This post explains the main types and what they do. The specific devices and routine for any child are prescribed by the care team.
Why contractures happen, and why these tools help
As Duchenne weakens muscles, the balance of pull across a joint changes, and muscles and tendons can shorten over time. This tightening, called a contracture, reduces the range of movement at the ankles, knees, hips, and later the elbows and wrists.
Stretching, orthoses, and standing all aim to counter that tightening by keeping joints in a good position. Rehabilitation, including stretching and orthotic management, is part of standard Duchenne care.

Ankle-foot orthoses and night splints
The most common orthoses in Duchenne are ankle-foot orthoses, often called AFOs. Worn most often at night while walking is still possible, they hold the ankle in a neutral position to slow tightening of the calf and Achilles tendon.
Night splints are usually better tolerated than daytime ones while a child is still walking, because daytime AFOs can interfere with the way a child compensates to stay on their feet. The timing is individual and set by the team.
Knee-ankle-foot orthoses
As walking becomes harder, some children use longer braces called knee-ankle-foot orthoses, or KAFOs, which support the knee as well as the ankle. In some cases these can extend assisted standing or walking for a period after unaided walking would otherwise stop.
KAFOs need careful fitting and a child who can tolerate them, so they suit some children and not others.
Standing programs
Once a child spends most of the day sitting, standing programs help. Using a standing frame or a wheelchair with a standing function provides regular weight-bearing, which supports the legs, hips, and spine and may help bone health and comfort. Orthoses and standing are part of rehabilitation management as Duchenne progresses. (Rehabilitation Management of the Patient With Duchenne Muscular Dystrophy, PubMed) For background, see bone health in DMD and losing ambulation in Duchenne.
Regular standing also helps stretch the hips and knees that sitting tends to tighten.
Stretching is still the foundation
Devices work best alongside daily stretching, usually taught by a physiotherapist for families to do at home. Splints and standing extend and support stretching rather than replacing the hands-on routine.
Consistency matters more than intensity. A short daily routine generally beats occasional longer sessions.
Comfort and tolerance come first
Any orthosis or standing routine only helps if it is actually used, so comfort and fit are essential. Skin should be checked for pressure, and a device that causes pain or sores needs review rather than perseverance. For background, see skin and pressure care for wheelchair users with Duchenne.
A device the child can tolerate and use is better than a theoretically ideal one that stays in the cupboard.
What is still uncertain
The best timing and combination of orthoses and standing vary by child, and evidence for exact schedules is limited. What is consistent is that keeping joints mobile and supporting posture, through stretching, splinting, and standing together, is a core part of rehabilitation in Duchenne.
