The Gait Lab works primarily with patients who have neurological conditions that affect their ability to walk or maintain postural stability. In addition to analyzing patients with neurological problems, we have worked with amputees completing a variety of activities of normal daily living in the Gait Lab to help in designing a prosthetic knee device.
We can perform data analysis on gait and posture by using a variety of high-tech equipment and software available in our lab. Examples of data analysis include measuring joint angles or ground reaction/joint forces for an entire gait cycle, or the duration of a desired activity, and calculating the center of pressure or postural sway of a patient while standing still over a period of time.
Recent Studies performed in the Gait Lab:
- Normal Pressure Hydrocephalus Study – gait analysis, instrumented treadmill, center of pressure force plate, accelerometer
- Multiple Sclerosis (MS) Study – gait analysis
- Hip Flexion Assist Orthosis Study with MS patients
- Cerebral Palsy patients – gait analysis
- Third Frontier Prosthetic Knee Project – gait analysis, activities of daily living
- Parkinson’s DBS Research – center of pressure force plate
- Throw Right – baseball pitching biomechanical analysis
- Golf Study – golf swing biomechanical analysis and EMG
- NASA Instrumented Harness Study – instrumented treadmill
- Exotendon Research Study – gait analysis, instrumented treadmill, and EMG
- Total Knee Arthroplasty Study – gait analysis, activities of daily living
- Motion capture data for various activities (gait, activities of daily living, etc.)
- Temporal and Spatial Data for gait analysis – cadence, velocity, step/stride length, step width, etc.
- Kinematic Data – various joint angles (focus on lower extremity)
- Kinetic Data – joint forces, moments, and powers in addition to ground reaction forces (focus on lower extremity)
- The Kistler Force Plate can provide a postural stability assessment and calculate the path of the center of pressure while standing still for a length of time.
- The instrumented treadmill provides ground reaction forces for both feet simultaneously in X-, Y-, and Z-directions for a continuous walk at various speeds
- Typical gait analysis lasts approximately one hour per patient and data analysis usually can be completed within a week after data collection (usually a couple days)
- Motion Capture System
- 8 infrared Eagle Digital RealTime System (Motion Analysis Corporation) cameras mounted on the walls to collect motion capture data.
- EVaRT and Cortex software : Under a single software environment we can set up, calibrate, capture motion in real-time, capture motion for post processing, edit and save data in the format of your choice.
- OrthoTrak software : OrthoTrak is a fully automated, three-dimensional, clinical gait measurement, evaluation and database management system. OrthoTrak allows the clinician to easily record the patient's physical measurement data with the gait report, and quickly compile technical data into simple, easy to read, charts and graphs.
- Adhere reflective markers to the body at specific anatomical locations and record various motions in the center of the lab (gait, activities of daily living, sports, etc).
- AMTI Force Plates: We have two small force plates and one large force plate in the ground to provide kinetic data to go along with the kinematic data we get from just the markers when collecting with the Motion Analysis software.
- Kistler Force Plate: Another force plate we use in the lab for measuring center of pressure and postural stability. Collect and analyze data with BioWare software.
- Head Accelerometer: We may also combine a head accelerometer test while performing the postural stability analysis on the Kistler force plate. Sampling rate for the accelerometer set at 93 samples/sec. Data analysis completed using MATLAB software.
- Instrumented Treadmill: A dual-belt dynamometric treadmill for the continuous dynamic measurement on each leg, and recording of the 3 spatial components (3D) of the ground reaction forces while walking.
