Motion Analysis Lab

The Motion Analysis Lab was established in September 1998 when the Department moved into the newly constructed Health Sciences Building. It currently contains a six-camera 3-dimensional motion analysis system from Motion Analysis Corporation that is synchronized with two-AMTI force plates and an eight-channel EMG unit. Analysis software includes Orthotrak (Motion Analysis Corporation's gait analysis program), Kintrak (Motion Analysis Corporation's generalizable motion analysis program), and Run Technology's EMG analysis software package.

Balance Master
Sensitive cameras are used to track and analyse a patient's motion.

In addition, the laboratory contains Neurocom's Smart Balance Master and Balance Master. Each system has two force plates synchronized to computer software programs for the assessment of postural control deficits. They also provide computerized feedback for specific balance training protocals. The Smart Balance Master contains a mobile visual surround and mobile force plates to differentiate between the visual, proprioceptive/exteroceptive, and vestibular components of postural control.

Finally, the lab has a treadmill and suspended ambulation equipment. A sitting pressure mapping system is currently on order. The department also has a portable 4 channel EMG system and isokinetic testing equipment. Additionally, equipment is available in an adjoining lab to measure energy metabolism.

ProMotion golfing equipment        golf swing

Use of the golf swing as a physical therapy adjunct in individuals with chronic stroke ( Ann R )

The golf swing is being used as an example of a bimanual activity to assess the effects of forced used in the mioderatekly to severely impaired hemiplegic upper extremity. In addition, this activity requires weight shift onto the hemiplegic lower extremity as well as controlled trunk rotation. Changes in postural control are also being examined in this context


Development of postural control for the community ambulatory.

As our population ages, there is an increased demand for ambulation assistive devices. One problem with currently available walkers is the tendency to cause forward trunk flexion. This project is assessing walker design variations that are functional for the community ambulatory and also decrease this tendency towards forward flexion.

Neurologic orthotics research Contact: Ann Karas Reinthal

Ankle foot orthoses used by individuals with cerebral palsy and stroke are being investigated. Systemic variation of a floor reaction AFO is being studied in individuals with CP ambulating with a crouch gait. Also, the lab is assessing various orthotic design features used post stroke.


The entropic analysis of time series following sudden load events and muscle fatigue based on electromyography data between subjects with and without low back pain.

Sudden Load Response Time Test   Sudden Load Response Time Test

Sudden response time test: Muscle response time to a sudden load was measured by dropping a 6.4 Newton weight approximately 1.8 meters onto a load cell mounted in a hand-held tray while the standing subject was blindfolded.
