Human Performance and Biodynamics Lab

Clinical Gait Analysis

Quantitative motion analysis is useful in identifying the underlying causes for movement abnormalities in pathologic patient groups such as in patients with knee osteoarthritis or cerebral palsy. This analysis will be used to create dynamic computer models of how patients move.  From these models, the lab team will be able to measure complex movement patterns that are not easily detected through simple visual inspection.Dora

Our Team Approach

Orthopaedic surgeons, physical therapists, biomedical engineers, and medical students are all involved in the Human Performance and Biodynamics Lab. As a result of these collaborations, we are positioned to solve challenging problems that are often multi-disciplinary in nature. To ensure families become involved, our team thoroughly explains the process of motion analysis and its effect on treatment outcomes. The Human Performance and Biodynamics Lab take referrals from various sources for clinical gait analysis, clinical balance and proprioceptive testing, including the WSSU Community Care Clinic, which provides clinical services for the surrounding underserved community.

What to Expect at the HP&B Lab

A typical visit will take approximately 1.5 to 2.5 hours to complete. Patients will undergo a variety of testing in the lab which will include:

  • Clinical Examination- A physical therapist will examine the patient and test muscle strength and range of motion of the hips, knees, and ankles.
  • GaitRite Analysis- Patients will be asked to walk across a carpet walkway while being video taped with a camcorder.
  • 3D Motion Analysis- Reflective markers will be placed on the patients' skin so that high speed cameras can follow the movement of the patient.
  • EMG recordings- Sensors will be placed on the patients' skin over specific muscles to record the electrical activity for each muscle.

DoraWhat to Bring for your Visit

Most patients that come in for motion analysis will wear a bathing suit or other tight fitting clothing which allows the therapists to record the patients' movements without baggy clothing obstructing the hips, knees, or ankles. Patients that walk with the help of an assistive device - braces, crutches, walkers, etc. - should bring them to their session so that a complete assessment can be made of the patient's case. These assessments will include video recordings made of the patient walking with and without the assistive device.
