What happens when a foot, ankle, knee, spine, or arm still functions, but pain, weakness, deformity, injury, or poor joint control makes movement difficult?
That is where orthotics enter rehabilitation care. For anyone asking what an orthotic is, an orthotic is an external device that supports, aligns, protects, positions, or controls an existing part of the body. It does not replace a missing limb. Instead, it helps the body use the limb or joint in a safer and more functional way.
Some orthotic devices look simple. A foot insert may redistribute pressure inside a shoe. Others involve several joints and extend from the foot to the thigh or hip. A spinal brace serves another purpose altogether. The device, therefore, should follow the clinical need.
At KARE, we approach orthotics through assessment, device selection, fitting, user education, rehabilitation, and follow-up. We provide custom and prefabricated solutions for the foot, ankle, knee, hip, spine, upper limb, fracture care, paediatric requirements, diabetic foot care, and other mobility needs.
What Is an Orthotic and What Does It Do?
People often use the words orthotic, orthosis, brace, support, and splint for similar products. In clinical care, an orthosis refers to an external device designed to change how a body segment functions.
An orthotic may hold a joint in a selected position. It may guide movement instead of stopping it. Some designs redistribute pressure. Others compensate for muscle weakness, protect injured tissue, prevent unwanted joint motion, or assist alignment during walking. This distinction separates clinical orthotics from ordinary cushioning products.
A soft shoe insert bought for general comfort does not automatically perform the same job as a prescribed foot orthosis. In the same way, an elastic knee sleeve cannot provide the same movement control as a brace with hinges, straps, and defined range settings. For this reason, we start with the person rather than the product.
During an orthotic assessment, we may examine muscle power, joint movement, limb alignment, skin condition, deformity, pain, footwear, gait, occupation, home environment, and the activities the user wants to perform.
For younger users, our paediatric orthosis range covers support options for the foot, ankle, knee, hip, spine, and upper limb as children grow.
How Do Orthotic Devices Work for Mobility and Joint Support?
Orthotic devices influence the forces acting on a joint or body segment. Take foot drop as an example. A person may struggle to lift the front of the foot during the swing phase of walking. The toes can drag against the ground. An ankle-foot orthosis can assist foot position and ankle control so the person can move the leg through the step with greater control.
A foot orthosis deals with a different problem. If one area under the foot receives excessive pressure, we may design the insert to spread the load across other areas.
A knee brace might restrict one movement but allow another. A spinal orthosis may restrict movement across selected spinal segments while supporting the trunk. These situations involve different problems and force requirements, so the appropriate brace will also vary. That is why buying a brace by diagnosis alone often gives poor results.
Orthosis vs Prosthesis: What Is the Difference?
The difference between orthosis vs prosthesis starts with one basic question: does the body part still exist?
| Feature | Orthosis | Prosthesis |
| Primary purpose | Supports or controls an existing body part | Replaces a missing body part |
| Typical goals | Alignment, protection, pressure control, joint stability, movement assistance | Replace lost limb function and support daily activity |
| Examples | AFO, KAFO, spinal brace, wrist orthosis, foot orthotics | Prosthetic leg, hand, foot, or arm |
| Clinical focus | Position, movement, pressure, fit, function | Socket, suspension, alignment, components, function |
A person may also require both.
Someone using a prosthetic limb on one side could need an orthosis on another body segment because of weakness, joint changes, or another condition.
If you are unsure where the two forms of care differ, our guide to prosthetics and orthotics and their key differences explains when a prosthesis replaces a missing body part and when an orthosis supports one that remains.
What Are the Main Types of Orthotics?
The term types of orthotics covers devices for almost every major region of the body. Clinicians usually classify them according to the joints or body areas they support.
Foot Orthotics
Foot orthotics fit inside footwear. They can redistribute pressure, support foot posture, alter loading patterns, or protect vulnerable areas.
Clinicians may recommend them for selected cases involving:
- flat foot
- plantar fascia symptoms
- arch problems
- pressure points
- diabetic foot risk
- foot alignment problems
- lower-limb loading issues
Not every insert performs the same job.
A functional orthosis may focus on how the foot moves. An accommodative design may concentrate more on pressure relief and protection.
Diabetic foot care deserves particular attention here. The national ICMR-INDIAB study included more than 113,000 participants across India and reported a weighted diabetes prevalence of 11.4%, while prediabetes prevalence reached 15.3%. Diabetes does not mean every person needs an orthosis, but the scale of the condition shows why foot assessment, pressure management, appropriate footwear, and early review remain important parts of lower-limb care.
For people with diabetic foot risk, pressure distribution and footwear fit require particular care. We provide prefabricated, customised, and digitised foot orthosis options, including diabetic and functional designs.
People who need more specialised pressure management can also explore our foot care and diabetic solutions, including footwear and orthotic options designed around different clinical requirements.
Ankle Foot Orthosis
An ankle-foot orthosis, commonly shortened to AFO, covers the foot and extends up the lower leg. We may use an AFO to control ankle position, assist a weak movement, reduce unwanted motion, improve foot clearance, or support medio-lateral stability. AFO designs vary considerably.
Some use a rigid shell. Others allow selected ankle movement through mechanical joints or flexible materials. We provide articulated AFO options using different ankle-joint systems where the prescription calls for selected movement control.
If foot drop, ankle weakness, or movement control is the main concern, our ankle-foot orthosis options show the different joint and support systems that may be considered after assessment.
Clinicians may consider AFOs for foot drop and selected conditions following stroke, spinal cord injury, cerebral palsy, muscular disorders, neurological disease, ankle instability, surgery, or injury. The diagnosis does not select the brace by itself. Muscle strength, range of movement, joint stability, gait pattern, and rehabilitation goals still influence the final prescription.
Knee Ankle Foot Orthosis
A knee ankle foot orthosis, or KAFO, extends from the foot across the ankle and knee. A KAFO becomes relevant when an AFO cannot provide enough control because weakness or instability also affects the knee.
This type of orthotic brace for leg support may contain mechanical knee joints, locking systems, release mechanisms, ankle controls, straps, and rigid structural sections. Selecting those parts requires careful work.
We examine knee stability, hip strength, ankle control, contractures, limb alignment, hand function, walking ability, body weight, and how the user will operate the brace during daily activity. Our KAFO options include different knee and ankle joint mechanisms because one locking or movement system does not suit every user.
For users who need support across both the knee and ankle, our KAFO range provides a closer look at available knee-joint, ankle-joint, and release mechanisms.
Hip Knee Ankle Foot Orthosis
A hip knee ankle foot orthosis, or HKAFO, extends the bracing system to the hip. Clinicians may consider this level of support when weakness or poor control affects several lower-limb joints.
Some HKAFO designs use reciprocal mechanisms that link movement between the hips. Others use different hip-joint arrangements according to the user’s physical capacity. Because these devices influence the whole lower limb, we assess more than one weak joint. Trunk control, upper-body strength, balance, hip movement, endurance, transfers, and the person’s daily environment can all affect whether a particular design remains suitable.
Where support needs extend through the hip, knee, ankle, and foot, our HKAFO solutions explain the types of multi-joint systems available for selected users.
Knee Orthotics
Knee orthotic braces cover a wide range of needs. Some provide ligament support. Others limit flexion or extension after injury or surgery. Certain designs use hinges that allow the permitted range of motion to be set. A knee brace may also provide compression and mechanical stability.
Fit remains important here. If the brace slips during walking, the hinge no longer aligns well with the knee. If straps produce excessive pressure, the user may struggle to continue wearing it.
The design must therefore match both the condition and the activity for which the brace is prescribed.
Spinal Orthotics
Spinal orthotics support or restrict movement across selected parts of the spine. Common categories include lumbar sacral orthoses and thoracic lumbar sacral orthoses. Clinicians may prescribe spinal braces during treatment for selected fractures, after surgery, for spinal instability, or as part of treatment for spinal deformities such as scoliosis.
We provide custom spinal orthoses, including LSO and TLSO designs for different spinal regions and clinical requirements. The amount of restriction required varies. More restriction is not automatically better. The prescribed device needs to control the required area while allowing the user to perform the activities permitted under the treatment plan.
For conditions where the spine requires more structured support, our spinal orthosis range includes LSO and TLSO options for different spinal regions and treatment requirements.
Upper Limb Orthotics
Upper limb orthotics include devices for the fingers, hand, wrist, elbow, and combinations of these areas.
Clinicians may prescribe them for:
- muscle weakness
- contracture management
- neurological conditions
- tendon problems
- wrist injuries
- post-fracture management
- post-operative positioning
- selected hand-function rehabilitation
Some braces hold the limb in one position. Other designs allow or assist selected movement.
We provide static and dynamic wrist, hand, and elbow orthoses according to the function required from the device.
Fracture and Trauma Bracing
Fracture orthoses protect healing bone and help control alignment during selected stages of recovery. The brace design changes with the location of the fracture.
A humeral fracture requires a different structure from a tibial fracture. Forearm, femoral, elbow, and wrist injuries create separate mechanical demands.
We provide rigid and semi-rigid fracture and trauma bracing for selected upper- and lower-limb injuries and post-cast rehabilitation.
Custom Orthotics vs Prefabricated Orthotics: Which Is Right for You?
One of the most common questions involves custom vs prefabricated orthotics. A prefabricated orthosis starts with a standard size or design. We then modify and fit it according to the user’s body measurements and treatment requirements.
A custom orthotic starts with individual measurements, casting, moulding, scanning, or another form of anatomical capture. We then design the device around that particular user. Neither option automatically suits every person.
Prefabricated braces can work well for some short-term conditions or less complex requirements. Custom devices become more relevant when the user needs more precise alignment, unusual sizing, pressure distribution, long-term bracing, deformity management, or control across several joints.
We fabricate our custom orthoses for individual users and modify prefabricated orthoses where required rather than treating the original factory fit as the final fit. If you are deciding between a ready-made brace and a customised device, our guide on choosing the best orthotics in India can help you compare the options around fit, function, and daily use.
Which Conditions May Require Orthotic Treatment?
Orthotic treatment can form part of care for musculoskeletal, neurological, congenital, traumatic, post-operative, and pressure-related conditions.
We do not prescribe a brace because of a diagnostic label alone. The prescription should address the functional problem created by that condition. For example, two people recovering from a stroke may walk very differently. One may need firm ankle control because the foot collapses during stance. Another may mainly struggle with toe clearance. Giving both users the same AFO may not solve either problem well.
Orthotic care may address foot drop, ankle instability, knee weakness, flat foot, spinal deformity, contractures, post-fracture protection, post-operative movement restriction, diabetic foot pressure, limb-position problems, and several neurological conditions.
Children may also require orthoses where muscle weakness, alignment, developmental conditions, or growth affect mobility.
What Are the Benefits of Orthotics?
The benefits of orthotics depend on the job the device needs to perform. A well-selected orthosis may assist joint stability, gait support, pressure relief, limb alignment, injury protection, posture correction, or controlled movement. But orthotics do not work by making every weak body part stronger. They change the mechanical environment.
An AFO may compensate for weak dorsiflexion. A foot orthosis may redistribute pressure rather than treat the underlying medical condition. A spinal brace may limit selected movement while the treatment team manages the actual spinal problem. This distinction affects expectations.
The brace should have a defined clinical purpose. The user and clinical team should know what movement, load, position, pressure point, or activity the device is intended to change. To see how these devices may fit into everyday walking and activity, our guide on how orthotics support comfort and mobility looks more closely at their practical role.
What Happens During the Orthotic Fitting Process?
A good orthotic fitting process starts before we fabricate or order the brace.
Clinical Assessment
We first review the medical history, diagnosis, surgery, previous bracing, pain, falls, footwear, work demands, home environment, and daily activities. The treatment goal needs definition at this stage.
Does the person need safer foot clearance? Knee stability? Pressure redistribution? Fracture protection? Wrist positioning? Those goals guide the decisions that follow.
Joint, Muscle, Skin, and Alignment Assessment
We examine joint range, muscle power, deformity, limb position, swelling, skin condition, sensation, and areas that cannot tolerate pressure.
For a lower-limb orthosis, our assessment does not stop at the area where symptoms appear.
Foot position can affect the knee. Ankle restriction can alter gait. Hip weakness can change how a KAFO performs.
Gait and Functional Assessment
Walking often reveals issues that a static examination misses. We may examine foot clearance, knee position, step length, loading, trunk movement, balance, turning, and how the person manages different surfaces.
For upper limb orthotics, the examination changes. We may assess reach, grip, joint position, muscle control, and task performance.
Measurement, Casting, or Digital Capture
Custom devices require accurate anatomical information. We may use measurements, casting, moulding, or digital technology depending on the device and the clinical requirement.
We also use CAD/CAM and selected advanced fabrication technologies where they suit the orthotic prescription.
Design and Fabrication
We then select materials, joints, straps, trim lines, padding, stiffness, corrective forces, and areas requiring pressure relief. Small design changes can alter performance.
A trim line that allows more ankle movement may help one user and reduce required control for another. A knee joint positioned poorly can affect the mechanics of an entire KAFO. Design needs to follow function.
Trial Fitting
During brace fitting, we check pressure, alignment, straps, joint position, skin contact, range of movement, and function. Lower-limb users may walk with the orthosis during this stage.
This allows us to assess what the brace does once body weight and movement enter the equation. Adjustments made here can change comfort, pressure, alignment, and movement control.
Training and Follow-Up
Delivery does not finish the process. Users need instructions covering wear time, fastening, skin checks, footwear, cleaning, activity, and signs that require clinical review.
Physiotherapy may accompany the orthosis when the user needs gait training, balance work, strengthening, stretching, or task-based rehabilitation.
Our orthotists evaluate, measure, design, fabricate, fit, adjust, train, and conduct follow-up for foot orthoses, braces, custom footwear, and more complex mobility support devices. Where required, we coordinate orthotic care with the wider rehabilitation programme.
How to Choose the Right Orthotic Brace
People searching how to choose an orthotic brace often compare price or brand first. That order can create problems. Start with the body segment and the movement that needs correction, assistance, restriction, or protection.
Before selecting any brace, consider:
- Which joint or body area requires support?
- What exact movement needs control?
- Will the user wear the device for walking, work, sport, sleep, or recovery?
- Does the user have skin sensitivity or reduced sensation?
- Does swelling change during the day?
- Can regular footwear accommodate the orthosis?
- Can the user manage straps, buckles, or joint-release mechanisms?
- Will rehabilitation change the required level of support?
- Does the case require custom fabrication?
- Who will review the brace after fitting?
This approach makes orthotic support for mobility more precise. It also avoids treating every brace within the same category as interchangeable.
Why Does Rehabilitation Continue After Orthotic Fitting?
An orthosis changes how the body moves or carries load. The user may need training to work with that change.
An AFO can alter foot clearance and ankle motion. A KAFO changes knee control. A new foot orthosis can shift how pressure travels across the foot. Upper-limb bracing may alter how someone performs grasping or reaching tasks.
The scale of rehabilitation need is substantial. The World Health Organization estimates that about 2.4 billion people globally live with a health condition that could benefit from rehabilitation. WHO also reports that in many low- and middle-income countries, more than 50% of people do not receive the rehabilitation they require.
For this reason, mobility rehabilitation may include gait training, balance exercises, strengthening, stretching, task training, footwear work, and home practice. We treat orthosis as one component within that programme when broader rehabilitation is required.
The device cannot replace every element of therapy, and therapy cannot correct a poorly selected or poorly fitted brace. Both parts need to support the same functional goal.
How Should Orthotic Devices Be Cared For?
Brace care affects both the device and the skin beneath it. We advise users to inspect the skin after wearing a new orthosis. Persistent redness, blistering, broken skin, swelling, numbness, or new pain requires review.
People with reduced foot or limb sensation need extra caution because tissue damage may develop before pain provides a warning.
Cleaning depends on the brace material. Heat can distort some thermoplastic devices, so users should follow the care instructions provided during fitting. Straps, padding, joints, liners, screws, and shell sections also need periodic checks.
Foot orthotics require suitable footwear. A well-made orthosis cannot perform as intended if the shoe compresses it, allows excessive movement, or lacks enough internal depth. If you want a simple routine for cleaning, checking, and protecting a brace between appointments, our guide to caring for orthotic devices covers the practical steps in more detail.
When Does an Orthotic Need Review or Replacement?
No single replacement schedule works for every orthosis. Children require regular review because growth changes limb dimensions and joint position.
Adults may need reassessment after weight changes, surgery, worsening weakness, changes in muscle tone, altered gait, new pain, or changes in activity. Wear also affects the device itself.
Cracked shells, loose joints, worn straps, compressed padding, poor fastening, persistent rubbing, or loss of movement control should prompt a review.
Users should avoid cutting, heating, bending, or adding large amounts of home padding to correct fit problems. Those changes can move pressure to another area or alter the mechanical action of the brace.
How We Provide Orthotic Care at KARE
We provide orthotic supports across the foot, ankle, knee, hip, spine, upper limb, trauma, diabetic foot, paediatric care, and other complex mobility requirements.
Our process begins with a one-to-one clinical consultation and can progress through evaluation, recommendation, fabrication, fitting, education, rehabilitation, and follow-up. We provide custom and prefabricated options because different users require different levels of control.
For custom orthoses, we build the device around the individual’s anatomy and treatment plan. For prefabricated options, we can modify and fit the brace according to the user rather than treating a standard size as the completed clinical solution.
Our orthotic range includes AFOs, KAFOs, HKAFOs, foot orthoses, spinal orthoses, wrist-hand-elbow devices, fracture braces, knee braces, and related rehabilitation devices.
We can also use CAD/CAM and selected fabrication technologies when they suit the prescription. The device comes after the assessment. That order remains central to our approach.
Conclusion: Choosing the Right Orthotic Starts With the Job It Must Do
The question of what an orthotic is has a simple definition, but selecting one requires much more than choosing a brace from a category.
A brace may help control an unstable knee. Another may lift the foot during walking. Foot orthotics may redistribute pressure. A spinal brace may restrict selected movement. An upper-limb orthosis may protect a joint or assist positioning. Those tasks require different materials, joints, shapes, trim lines, pressure areas, and fitting methods.
At KARE, we connect clinical assessment with device design, the orthotic fitting process, education, rehabilitation, and follow-up. We do not start with a generic brace and then try to make the person fit around it. We start with the body, function, daily requirements, and treatment objective, then select or design the orthosis that can perform that job.

Frequently Asked Questions
What is an orthotic in simple terms?
An orthotic is an external brace or support that assists, protects, aligns, positions, or controls an existing body part.
Are orthotics only for feet?
No. Orthotics can support the feet, ankles, knees, hips, spine, arms, elbows, wrists, hands, and other body areas.
What is the difference between an AFO and a KAFO?
An AFO controls the ankle and foot. A KAFO extends above the knee to support the knee, ankle, and foot.
Can orthotics help with pain?
They may reduce pain in selected cases by changing load, restricting painful movement, supporting alignment, or protecting injured structures.
Are custom orthotics better than ready-made braces?
Not in every case. Custom orthotics suit complex fitting or control needs, while fitted prefabricated braces can suit simpler requirements.
How long does an orthotic last?
Device life depends on material, wear, body changes, growth, activity, mechanical components, and changes in the person’s condition.
Who should fit orthotic braces?
An orthotist has specialist training in assessing, designing, fitting, and reviewing orthoses for different parts of the body.
Can someone wear a prosthesis and an orthosis?
Yes. A prosthesis can replace one missing body segment while an orthosis supports another existing body part.
Does an orthotic require rehabilitation?
Many users benefit from rehabilitation when the brace changes gait, balance, joint control, posture, or upper-limb function.
