Motion Analysis Lab



The Motion Analysis Lab researchers focus their work on three main activities:

1. Developing techniques for investigating the relationship between the mechanics of movement and the characteristics of the EMG data

2. Implementing methods for studying the neural control and biomechanics of posture.

3. Developing algorithms for ambulatory monitoring of movement disorders in patients with Parkinson’s disease.

The lab is equipped with a four-camera motion analysis system (Elite, BTS, Milan, Italy), a permanently installed force platform and two portable platforms (Kistler Instrumente AG Winterthur, Switzerland), and EMG equipment. One of the platforms is installed on a moveable platform that is controlled by servo-motors designed to study the effects of mechanical perturbations on postural control. Past work of the researchers in this lab included a) documentation of the association between changes of the mechanics of movement during the accomplishment of repetitive tasks (i.e., lifting and knee flexion/extension movements) and muscle fatigue; b) development and testing of vestibular prostheses for patients with neurovestibular disorders; and c) developing a test battery for studying the effects of microgravity on postural control. Current studies in the laboratory include the collection of wearable sensor data in patients with Parkinson’s disease to develop algorithms for ambulatory tracking of motor outcomes.
