Running prostheses and returning to movement

An overview of how prosthetic foot structures for running and sports work, their areas of use and the factors that are assessed.

What is a running prosthesis?

A running prosthesis is a sports-oriented prosthetic foot structure designed for dynamic activities such as running and jumping. It is usually made in the form of a flexible carbon-fiber spring and aims to contribute to forward propulsion by returning a large part of the energy stored during the step.

Unlike prosthetic feet designed for daily use, running prostheses may not include a heel section and are shaped for the rhythmic running stride rather than for walking.

Whether a running prosthesis is suitable for a person is determined by assessing activity level, residual limb structure and sports goals together. The fitting is planned solely in line with a specialist physician's assessment and prescription/medical report.

How does a running blade work?

When the foot contacts the ground, the carbon-fiber spring bends and stores energy; in the take-off phase of the stride, it returns part of this energy and supports the running movement. This behavior is intended to contribute to the fluidity and efficiency of running.

The stiffness and curve of the spring differ according to the person's weight, height and targeted activity level. The suitable structure is determined through a joint assessment by the physician and the prosthetic technician.

  • Spring stiffness that varies according to the person's weight
  • A curved structure shaped according to activity level

Overview of sports-oriented foot types

The grouping below offers a general overview by intended use; it focuses on function, not on brand or model. The choice suitable for the person is made through assessment.

Sprint- and speed-oriented springs

Spring structures intended for a high pace over short distances, with an emphasis on energy return.

Endurance and everyday running

Structures designed for longer-distance running at a steady pace and for active pursuits are considered in this group.

Sports knee structures

For above-knee use, special-purpose knee structures intended to support swing and stance during dynamic activities may be considered.

Assessment by surface and type of running

The behavior of a running prosthesis may be experienced differently depending on the surface run on and the type of activity. Surfaces such as a track, asphalt and natural terrain can create different needs for balance and adaptation.

The surfaces on which the person will run and the types of activity they will do are taken into account when planning the suitable spring structure and alignment.

Balance, strength and safe use

Because running prostheses are used under intense and dynamic loads, correct alignment and regular maintenance are important for safe use. Appropriate initial training helps the person adapt gradually to running with the prosthesis.

When the exercise and familiarization process is planned under a physiotherapist's guidance, the aim is to support both the sense of confidence and the quality of movement. This process varies from person to person.

Technical factors that determine suitability

The headings below are for information purposes. Individual values and suitability are determined through measurement and the physician's assessment.

The person's weight

The stiffness category of the spring and the durability requirement are assessed together with the person's weight.

Activity level

The targeted running intensity and frequency play a role in determining the suitable spring structure.

Spring height and alignment

Residual limb length and alignment are adjusted individually for a balanced and efficient running stride.

Residual limb structure

The length and condition of the residual limb are assessed together with socket and connection options.

Process

The running prosthesis assessment process

1

Physician's Assessment

The fitting begins with a specialist physician's assessment and a prescription/medical report; sports goals are reviewed.

2

Measurement and Planning

Activity level, residual limb structure and the targeted activity are assessed; the suitable structure and the service plan are determined.

3

Trial and Fit

A spring trial and alignment are carried out; settings are adapted to the individual.

4

Training and Follow-up

Training is given for gradual adaptation to running with the prosthesis; follow-up is provided for check-ups and, when necessary, readjustment.

Frequently asked questions

Can I also use a running prosthesis in daily life?

Running prostheses are designed for running and sports; a separate prosthetic foot is usually used for everyday walking. The scope of use is planned by the physician and technician during the assessment.

How long does it take to adapt to a running prosthesis?

The adaptation process varies from person to person and progresses gradually. Regular practice under a physiotherapist's guidance is intended to support movement quality and confidence.

Who is a running prosthesis suitable for?

Suitability is determined by assessing activity level, residual limb structure, general health and sports goals together. The decision is made solely on the basis of a specialist physician's assessment.
