A strap used in an orthosis or rehabilitation product has to combine support with adjustability and user comfort. The correct construction depends on the body area, required movement, contact pressure, fastening method and how often the product is fitted and removed.
Start with the clinical function of the component
Lécuyer’s medical page describes rigid, elastic and hook-and-loop straps for orthoses, exoskeletons and other support or rehabilitation applications. The textile may stabilise, position, close, adjust or distribute pressure. These functions should be defined before the material is selected.
Rigid, elastic or hook-and-loop: choose by movement and adjustment
| Construction type | Typical design objective |
|---|---|
| Rigid strap | Stable positioning and controlled support where elongation is not desired |
| Elastic strap | Controlled accommodation of movement or pressure changes |
| Hook-and-loop compatible strap | Frequent adjustment, opening and refitting |
| Hybrid / assembled solution | Combination of support, adjustment and hardware integration |
Comfort is a technical requirement
Width, edge feel, surface texture, flexibility and local pressure all influence tolerance during wear. A strap that is mechanically adequate but creates pressure points or is difficult to adjust can reduce the usability of the final product.
Specify elasticity with measurable behaviour
“Elastic” can describe very different products. The target elongation, recovery and force at a defined extension should be agreed so that the strap provides repeatable support rather than uncontrolled stretch.
Consider repeated opening, closing and cleaning
Orthotic and rehabilitation products may be fitted and removed frequently. Fastening performance, edge wear, stitch integrity and behaviour after the intended cleaning process should be considered during development.
Integrate hardware and anchoring points
Lécuyer states that it can assemble rivets, eyelets, handles and other plastic or metal components. These interfaces should be positioned to avoid local discomfort and validated for the loads generated in use.
Prototype on the real device geometry
The most useful prototype is installed on the actual orthosis, exoskeleton or support structure. This confirms routing, adjustment range, pressure distribution, user handling and interference with joints or other components.
Define responsibilities for the final medical product
A custom textile component can support the performance of a medical or orthotic product, but the manufacturer of the final device remains responsible for its design, risk management and applicable regulatory requirements. Component specifications should therefore be linked to the final product’s technical file and validation plan.
From textile component to usable support system
For medical strap applications, the best specification connects mechanical support, adjustability, comfort, assembly and the way healthcare professionals or patients will actually use the product.
Frequently asked questions
What is the difference between rigid and elastic medical straps?
Rigid straps are used where dimensional stability and controlled positioning are required, while elastic straps allow defined extension and recovery where movement or pressure accommodation is needed.
Why does strap width matter in an orthosis?
Width influences pressure distribution, comfort, routing and compatibility with the device geometry.
Can hook-and-loop systems be integrated into custom straps?
Yes. Lécuyer states that its medical solutions can be compatible with removable or hook-and-loop support systems, subject to project requirements.
Who is responsible for regulatory compliance of the final medical device?
The manufacturer placing the finished device on the market is responsible for the applicable regulatory obligations, risk management and validation of the complete product.
