RPE Movement analysis lab

The Department of Rehabilitation and Prevention Engineering runs its own movement laboratory which is equipped with a modern and technically high-end VICON movement analysis system. Particular biomechanical models developed by the RPE enable the analysis of upper extremity movements as well as the analysis of gait. The goal is, to support the doctor in his decision-making regarding therapy for movement-impaired patients through the use of objective analytical procedures and thereby to optimize the therapy and improve the ability to adapt to a patient’s individual needs.

Clinical Gait Analysis

Marker arrangement for gait analysis Marker arrangement for clinical gait analysis

Since the traditional observation of human gait in regular clinical practice is often insufficient, researchers in the Department of Rehabilitation and Prevention Engineering have focused on gait analysis based on optoelectronic tracking systems. During this analysis light-reflecting markers are attached to the lower extremities. The three-dimensional movement trajectory of these markers is subsequently recorded by high-resolution cameras. Combining this information with a biomechanical model recording is made of the joint movements occurring during walking. By means of the measurement data obtained one gains objective results which are useful for comparison. These allow statements to be made regarding a standard gait sequence and the recognition of deviations from the standard. Thus the data obtained can be used for the successful monitoring of traditional therapeutic measures and operations. Furthermore the data can also contribute to the design of individual, medical aids e.g. orthoses.

 

Capture of upper extreities movements

Movement disorders and function movement limitation cause pain and disable. Once the upper extremities are affected the performance of daily activities is often hardly possible or severely impaired. To enable the analysis of upper extremity movements, a biomechanical model has been developed in the Department for Rehabilitation and Prevention Engineering and used for the objective and quantitative analysis of movement in the upper extremities. For the recording of the kinematics of the upper extremity, a triplet consisting of three light reflecting markers is attached to the hand, forearm, upper arm; and torso. Joint centers and joint coordinate systems of clavicular joint, shoulder, elbow and wrist are determined during a static trail. By means of this measurement procedure the three-dimensional joint position can be determined, which gives the clinician important information about movement quality and supports the introduction of suitable therapeutic measures.
