The Role of Orthotics in Improving Mobility After Stroke
Stroke can have a significant impact on a person’s mobility. Changes in muscle strength, coordination, balance, muscle tone, and movement control may make standing and walking more difficult. Some stroke survivors experience problems such as foot drop, ankle instability, or difficulty controlling the position of the foot during walking.
Orthotics can play an important role in supporting mobility during stroke rehabilitation. An orthosis is a device designed to support, align, protect, or assist a specific part of the body. For stroke survivors, orthotic treatment commonly focuses on the lower limb, particularly the foot and ankle.
When appropriately prescribed and fitted, an orthosis can provide mechanical support while a person continues working on strength, balance, coordination, and functional movement. Orthotic treatment is generally one part of a broader rehabilitation programme and should be tailored to the individual’s needs and goals.
What Are Orthotics?
Orthotics refers to the assessment and use of orthoses to support movement and physical function. An orthosis can help influence the position or movement of a body part, depending on its design.
Following a stroke, an orthosis may be considered when weakness, altered muscle tone, reduced motor control, or changes in joint positioning affect mobility. The device can provide external support that complements active rehabilitation.
The Role of an Orthotist
An orthotist is a healthcare professional who assesses physical movement and prescribes, designs, fits, and reviews orthoses. During an assessment, an orthotist may consider muscle strength, range of motion, balance, walking pattern, muscle tone, footwear, lifestyle, and rehabilitation goals.
This individualised approach helps determine whether orthotic treatment is appropriate and which type of device may provide suitable support.
How Stroke Can Affect Mobility
Stroke can affect the areas of the brain responsible for movement and coordination. Depending on the location and severity of the stroke, a person may experience weakness or reduced control on one side of the body.
Walking may become slower, less stable, or more physically demanding. Some people may have difficulty lifting the front of the foot, controlling the ankle, or placing the foot correctly during each step.
Common Mobility Challenges After Stroke
The Role of Orthotics in Improving Mobility After Stroke
Mobility difficulties following stroke may include:
Foot drop
Ankle weakness or instability
Difficulty clearing the foot during walking
Changes in lower-limb alignment
Altered muscle tone
Reduced coordination
Changes in walking speed or efficiency
The presence and severity of these difficulties vary between individuals.
The Role of Ankle-Foot Orthoses
An ankle-foot orthosis, commonly known as an AFO, is one of the most frequently used orthotic devices for people experiencing lower-limb difficulties after stroke.
An AFO supports the foot and ankle and can influence their position during standing and walking. Different AFO designs offer different levels of flexibility and control.
Supporting Foot Position
An AFO may help maintain the foot and ankle in a more functional position during walking. This can be particularly useful for people who have difficulty controlling their foot because of weakness or reduced motor control.
The exact effect depends on the design of the orthosis and the individual’s physical presentation.
Managing Foot Drop
Foot drop is a common mobility problem following stroke. It occurs when a person has difficulty lifting the front part of the foot while walking.
Without sufficient foot clearance, the toes may catch on the ground as the leg moves forward. This can alter the person’s walking pattern and may contribute to trips or balance difficulties.
Improving Foot Clearance
An appropriately selected AFO can help support the foot in a position that improves clearance during the swing phase of walking. This may allow the leg to move forward with greater control.
An AFO does not restore neurological function, but it can provide mechanical assistance while the person continues rehabilitation to improve active movement.
Supporting Ankle Stability
Ankle instability can make weight-bearing and walking more difficult after stroke. A person may struggle to maintain the foot in a stable position when standing or taking a step.
An orthosis can provide external support around the ankle and help limit unwanted movement, depending on its design.
Supporting Weight-Bearing
A more controlled foot and ankle position can provide a stable base during weight-bearing. This may help some individuals practise standing and walking activities more effectively as part of rehabilitation.
The appropriate amount of support is different for each person. Excessive restriction may not be suitable for everyone, which is why assessment and professional fitting are important.
Orthotics and Gait Rehabilitation
Gait refers to the way a person walks. After stroke, gait may change because of weakness, altered muscle tone, reduced coordination, balance problems, or compensatory movement patterns.
Orthotic treatment can help influence certain aspects of gait by controlling foot and ankle movement.
Working Alongside Physiotherapy
Orthotic treatment is often used alongside physiotherapy. Physiotherapists may work on strength, balance, coordination, walking practice, and functional mobility.
An orthosis can provide physical support during these activities. This may allow the person to practise movement with improved foot and ankle positioning while continuing to develop active control.
Choosing the Right Orthosis
There is no single orthosis that works for every stroke survivor. The appropriate device depends on the person’s physical presentation and functional requirements.
An orthotist may consider muscle strength, joint range of motion, muscle tone, balance, walking ability, footwear, and daily activities when selecting an orthosis.
Custom and Prefabricated Options
Some orthoses are manufactured in standard sizes, while others are custom-made for an individual’s anatomy and functional needs.
A prefabricated device may be appropriate when a standard design provides the required level of support. A custom orthosis may be considered when more specific alignment, pressure distribution, or movement control is required.
Comfort and Fit Are Important
For an orthosis to be useful in everyday life, it needs to be comfortable and appropriately fitted. Poor fit can contribute to pressure, rubbing, discomfort, or skin irritation.
Stroke survivors should follow the wearing instructions provided by their healthcare professional and monitor their skin regularly, particularly when using a new device.
Footwear and Orthotic Use
Footwear needs to accommodate the orthosis appropriately. Shoes that are too narrow or do not provide sufficient space may make the device uncomfortable or difficult to use.
An orthotist can provide advice about suitable footwear and assess the orthosis with the shoes the person commonly wears.
Monitoring Orthotic Treatment
Stroke recovery can involve changes in physical function over time. Improvements in strength, balance, and motor control may change a person’s orthotic requirements.
Regular reviews can help determine whether the device continues to provide appropriate support.
When an Orthosis May Need Adjustment
Changes in walking ability, persistent discomfort, skin irritation, difficulty putting on the device, or changes in physical function may indicate that an orthotic review is appropriate.
The orthotist can assess the device and determine whether modifications, adjustments, or a different design may be required.
Supporting Independence Through Mobility
Mobility is closely connected with independence and participation in everyday life. Being able to move safely around the home, attend appointments, participate in rehabilitation, and engage in community activities can be important goals following stroke.
An orthosis may provide support that helps a person participate in these activities while continuing to work on their rehabilitation goals.
Orthotics as Part of a Personalised Approach
The purpose of orthotic treatment should be based on the individual’s needs rather than a standard approach. One person may require an orthosis primarily for foot drop, while another may need greater ankle stability or support with lower-limb alignment.
A personalised assessment helps ensure that treatment addresses the person’s specific challenges.
Conclusion
Orthotics can play a valuable role in supporting mobility after stroke. For people experiencing foot drop, ankle weakness, instability, or difficulty controlling foot position, an appropriately selected orthosis may provide mechanical support during standing and walking.
Orthotic treatment is not a replacement for stroke rehabilitation. Instead, it can complement physiotherapy and other rehabilitation strategies by supporting the foot and ankle while the individual works toward improved strength, balance, coordination, and functional mobility.
Because every stroke survivor has different needs, professional assessment is essential when considering an orthosis. Ongoing review can also ensure that the device remains comfortable, functional, and appropriate as recovery progresses.
With personalised orthotic care and a coordinated rehabilitation approach, stroke survivors can receive the physical support they need to work toward greater mobility and independence in everyday life.
