An amputation, paralysis, an accident or a stroke can all cause their own deviations in gait patterns. A gait analysis can help researchers and therapists to understand why a person walks in a certain way and help to determine which treatment will be the most effective for that specific person.

RRD has its own specialised movement lab where, with the help of equipment such as 3D infrared cameras, EMG equipment and force plates, we can make measurements for the purpose of scientific research or clinical decisions.

Ambulant measurement method
In addition, we have developed an ambulant measurement method that we can take to any desired location to register and analyse the movements of people during daily activities. With the help of accelerometers, gyroscopes, magnetometers, EMG, advanced algorithms and data fusion, we determine the movements of limbs and the forces that are generated on the body during the movement.

New research area
With this approach, we can produce movement data from gait patterns with the same precision as in our movement lab while being on-site. Furthermore, we will expand this ambulant measurement method with data about the forces under the soles, and we will use it in a wider variety of populations. With ambulant sensors, we are opening up a new research area in the field of biomechanics and motor control and we are obtaining new knowledge about deviant behaviour of the motor system during everyday activities, both simple and complex.

Target groups
We have a considerable amount of experience with post-stroke patients, people with amputations and children with spastic muscles due to brain disorders. Furthermore, we are increasingly focusing on other groups such as athletes or frail elderly people. In the last group, we are mainly studying balance in the context of preventing falls.



In the SMOVE project (Interreg), Dutch and German partners are developing a system for assessing and monitoring movements in patients with (neuro)motor disabilities. The system can measure the quality and quantity of movements, together with muscle activity. We focus on three specific target groups: patients after a stroke, after a hip or knee replacement and patients with Parkinson’s disease. The system enables patients to undergo (part of) their treatment at home. As a result, their movements can be better monitored, caregivers can evaluate these movements and less clinical treatment is necessary.

SensoRun – Injury prevention among runners

RRD has performed the first continuous 3D measurements of runners throughout a marathon. Based on these measurements, we develop a system that will give real-time feedback about changes in the running technique as a consequence of fatigue. Aim is to prevent injuries to recover faster.

XoSoft – ‘High-tech trousers’ for mobility and balance support

RRD, Saxion and others are developing a ‘soft exo-skeleton’ (Horizon 2020). This ‘high-tech trousers’ actively supports the musculature of elderly people during walking and in keeping balance. The purpose of XoSoft is to provide elongated independent living at home and at work.
