Underarmsstöd

Underarmsstöd, or underarm support, refers to a device or feature intended to support the forearm and underside of the upper arm. It can be integrated into chairs, workstations, or prosthetic and orthotic devices, or exist as a separate pad or cushion placed under the arm. The goal is to distribute weight, reduce muscular effort in the shoulder and neck, improve alignment of the elbow and wrist, and prevent pressure points.

Common forms include fixed or adjustable pads attached to chair armrests or desk surfaces; underarm cushions built into wheelchair seating or office chairs; orthotic components that cradle the forearm for injury rehabilitation; and prosthetic attachments that stabilize the residual limb. They may be made from foam, gel, silicone, or microfiber and covered with fabric for comfort. Materials and attachments vary from simple straps to rigid brackets.

Uses span ergonomic work environments to medical rehabilitation. In office settings, underarmsstöd can lessen forearm strain during typing and mouse use, while in rehabilitation they support the arm during healing from shoulder, elbow, or wrist injuries. In mobility aids or prosthetics they stabilize the limb and distribute loads to reduce fatigue.

Key design considerations include comfort, fit, adjustability, hygiene, and the risk of creating new pressure points or restricting circulation. Proper setup aligns the forearm with the elbow and wrist, so the elbow is near a 90-degree angle and the forearm rests neutrally.

Overall, underarmsstöd is a versatile concept in ergonomics and assistive devices aimed at reducing upper limb strain and supporting posture, with applications across work, clinical, and mobility contexts.
