Conventional walking aids show major shortcomings

The correct application of a walker is the most important prerequisite for a quick and successful therapy. However, the patients often do not have sufficient information about the use of orthopedic devices.

So it was a central question of this project to improve the dialogue between therapist and patient in order to accelerate the rehabilitation process or to make it more effective.

WERKSDESIGN has studied conventional walking aids as part of a field study: Handles cause an excessive bending of the wrists, small contact surface on the handle produces selective pressure peaks (numbness).

During the displacement of the body weight a feeling of instability occurs because the forearm follows the walker only limited.

Each year 1.25 million sportspersons get hurt so badly that they need medical treatment and possibly surgery is required. 60% of these cases relate to the moving body parts.

In order to prevent the loss of stability during displacement of the body weight a parallelogram system is integrated directly below the handle. If the patient is leaning on the crutch, the armrest automatically approaches the forearm. In addition, a spring effect is achieved with the patented mechanics.

This smart synchronous movement of the crutch favorise the movement pattern and strengthens the sense of security of the patients. Supportive effects are the ergonomic design of the handle and a flexible stand.

In the forearm support a sensor is integrated which detects the supporting forces, movements and the occuring accelerations. The load values are displayed in the e-crutch app and are compared with those values recommended by the orthopedist.

The chat function allows a contemporary, easy consultation between the therapist and the patient. Push messages to the patient increase the motivation of the user in complying with the treatment plan and act as a reward.
