Advantages - Ariel Performance Analysis System
General
APAS demonstrates significant advantages over other common approaches to
movement systems:
| First, except for specific applications requiring EMG or kinetic (force
platform) data, it is non-invasive. No wires, sensors, or markers need be
attached to the subject. |
| Second, it is portable and rarely requires any modification of the
performing environment. Cameras can be transported to the site and
positioned so as not to interfere with the subject. |
| Third, the scale and accuracy of measurement can be set to the levels
required for the activity being performed. Video equipment technology
currently available is sufficiently adequate for most applications requiring
accurate motion analysis and is normally the least expensive option,
particularly when two or more cameras are needed. |
Video-based
The ability to record the activity as a picture has a number of advantages:
| It allows the scientist to make intellectual decisions regarding the joint
center at each frame rather than using markers attached at the skin's
surface.
| Subsequent quantification would be possible since the video can be
re-examined at any time.
| Stick figure results can be overlapped with the video pictures for
effective result presentations. |

Areas of interest
Applications of the APAS usage include many areas of interest.
| Sport or athletic applications have included volleyball, soccer, American
football, tennis, track and field events, horse racing and jumping, and
golf.
| Medical research is using the APAS to quantify movement in Parkinson
patients with and without drugs and before and after surgical procedures.
| Job quantification
| task improvement,
| post-injury assessment
| employment evaluations
| risk assessment,
| worker's compensation
| disability evaluations
| ergonomic evaluations of job tasks
| job standardization can be useful in the workplace.
| Industrial applications include product design, analysis, and improvement
as well as such things as manufacturing hardware performances such as piston
movement accuracy.
| Artistic endeavors, such as playing the violin, the harp, and the piano,
have been examined biomechanically by APAS applications.
| Mammalian research has examined thoroughbred race horse performance,
feline locomotion, and monkey jumping performance.
| Forensic analysis have included injuries sustained in football,
gymnastics, horse racing, and running shoes.
| Space Research have included number of research studies at NASA.
| Rehabilitative usage include pre- and post-hip replacement functioning,
gait analysis, and comparisons of bilateral functions. |
