Human Performance Lab


One of the core research laboratories at the CARE is the “Human Performance Laboratory”, which hosts various state of the art teaching and research tools and equipment used for the advanced understanding of human movement and injury prevention. From studying gait and athletic events, reaching and preparing for an object for manipulation to respiration and subtle facial movements during speech, the “Human Performance laboratory” is equipped for our faculty and students to make breakthroughs and discoveries that will improve patient rehabilitation therapies. The main equipment and their possible uses of the “Human Performance Laboratory” are the following:

  • Qualisys 3-D motion capture analysis of joint motion and acceleration.
  • Force platform monitor of ground reaction forces for calculation and analysis of joint movements.
  • Accelerator sensor gloves for the evaluation of reaction forces from the upper extremities.
  • Eye tracking system for measuring a point of gaze and a motion of an eye relative to head.

An example of a study in the Human Performance Lab is used by Dr. Inae Gadotti, assistant professor of the Physical Therapy Department. Her study focuses on the eye and head movements of people with chronic neck pain suffered from car accident-related whiplash. The participants head movements are captured with 4-Camera Qualisys motion analysis system (QTM-Qualisys Track Manager, Version 2.5; Qualisys Inc.; Gothenburg Sweden), and the ASL mobile eye XG tracking system (Applied Science laboratory, Bedford MA, USA) is used to capture eye movement relative to head. Surface electromyography is also being used to detect muscle activity of Sternocleidomastoid muscle bilaterally during the head and eye movement. These multi-modal bio-signals provide innovative information to understand rehabilitation therapy. In addition, Dr. Kinsuk Matira & Dr. HaeYean Park of the Occupational Therapy Department are also studying how non-conscious memory can be utilized to facilitate upper extremity functional rehabilitation in stroke patients utilizing novel paradigm called “Repetition Priming”.
 To identify the effect of “Repetition prime” from motion data which are measured from 9-Camera QTM system. The study focused on the brain training using “repetition prime” toward utilization of occupational therapy for stroke patients. If the neural signal associated with repeated prime training is also acquired, it will add another qualitative metric to determine the effectiveness of the rehabilitation regime. Thus, comprehensive bio-signal measurement is imperative for an effective rehabilitation regime of an individual with disabilities.
