The Ariel Computerized Exercise System (CES), invented by Dr. Gideon Ariel, heralds a new era in physical rehabilitation, research, and conditioning. Ariel CES is the only system available that automatically monitors, controls, and modifies resistance and velocity while the person is exercising. It does this safely and efficiently, constantly adjusting itself to accommodate each person’s unique capabilities or limitations. Ariel CES also provides extensive and accurate measurements of movement, strength, and endurance with the capability for storage and subsequent comparison and analysis of the individual’s performance.

The Intelligent System

That’s why we call it the “Intelligent System” for rehabilitation and fitness. Ariel CES senses and responds directly to an individual’s performance in real time. In other words, the computer is able to control your movement and adjusts to your effort while you exercise. Not only does the Ariel CES sense and respond to specific motions. it also interacts with the individual, providing immediate visual and audio feed back during exercise.

At the heart of Ariel CES’s “intelligence” is a state of the art microcomputer system. The computer and its unique software assume the responsibility for controlling the precise force level. speed of movement. and temporal sequence to achieve a specific pattern of exercise. Unlike other systems, Ariel CES has the ability to adjust and modify its assignment throughout the entire exercise session.

The monitor,rovides complete performance

information on a continuous basis during

exercise. Running totals of work. repetitions.

and elapsed time are maintained.

The “user-friendly” screen instructions permit anyone to operate the system, even individuals who have never used a computer.

The average curve plot (solid graph) shows the

average exercise values measured for both the

up and down strokes. Optional comparisons to

previous performance (red line). or to an

“ideal” performance goal (green line l.

may also be included.

Flexibility of Use and


Key to the Ariel Computerized Exercise System is the flexibility it offers. Isotonic. isokinetie, or isometric exercise, or any combination of these exercise modes can be performed. In addition, the Ariel CES can control and measure velocity, resistance, power, work output, fatigue level, duration of exercise, or combinations of all five.

Another major value of the Ariel CES is its ability to run manual and preprogrammed sequences of exercises as well as customized individual exercise sequences. A physical therapist can follow prescribed testing or training protocols for patients or can

create and program unique procedures for specifically desired routines.

In fact, Ariel Computerized Exercise System encourages innovation and creativity… because the Ariel CES can adjust the speed or the resistance of an exercise throughout its range of motion … because the Ariel CES allows the application of an isometric contraction at a selected point within a movement … because the Ariel CES response can be controlled throughout the entire range of motion…the possibilities are endless.

Rehabilitation statistics report, in numerical format, the average measured values for a number of parameters of exercise and motk)n.

The Ariel CES is comprised of these basic components: The Multi-Function Exercise Station The Arm. Leg. Back Exercise Station The Computer Console The Monitor

The System Software The Printer (Optional)


What the CES Can Do

For the operator the Ariel Computerized Exercise System performs many critical functions. including the ability to:

*Rehabilitate and condition

� Measure and diagnose

� Record and evaluate results

*Control and monitor velocity in

each direction independently *Control and monitor resistance

in each direction independently

� Program the pyramiding of re

sistance or speed in each direction

� Program the range of motion in

� each direction

*Accommodate resistance until the individual reaches a prescribed level of fatigue during endurance training

� Display performance goal target as an incentive during exercise

� Store and retrieve performance data

� Compare current and previous performance data in color graph, chart or tabular form

� Generate performance profile of average and maximum exercise resuits for each repetition and for both up and down directions

� Illustrate in graphic format the force, work, power, and fatigue in relation to time, bar position, and lifting pace

� Calibrate dynamically force and velocity through the entire range of motion and verify results

The ARIEL PERFORMANCE ANALYSIS SYSTEM represents the latest enhancement to the proprietary biomechanical analysis system developed through more than a decade of research, software engineering, and hardware development/integration by Computerized Biomechanical Analysis (CBA) Inc., the acknowledged world leader in human performance analysis.

Now, for the first time, this, proprietary system is being made available to professionals in the fields of biomechanics, sports medicine, athletics, rehabilitation, forensics, and basic research. Over the course of years and through literally hundreds of analyses, this system has proven successful in the following areas of application:

� ATHLETIC PERFORMANCE – analysis of technique, performance limits and analysis of potential, injury and rehabilitation analysis, comparative analysis to world class and “elite” athlete performance. Analysis of “non-human” athletes such as race horses and dogs for selection and training.

� EQUIPMENT PERFORMANCE – analysis of the following types of equipment under “actual use” conditions: shoes, gymnastic equipment, tennis rackets, golf clubs, bicycles, strollers, prosthetic devices, protective pads and helmets, and various types of exercise equipment.

� FORENSIC BIOMECHANICS – determination of causes of injury through analysis of forces resulting from impact, falls, or being struck by objects. Determination of potential for injury from various types of activity and through the use and misuse of various equipment. Quantification of extent of injury, loss of use, or degree of recovery for individuals in relation to liability/compensation issues.

� COACHING AND PROFESSIONAL SPORTS – assessment of individual performance level and technique. Measurement of progress over time or through variations in technique. Evaluation of performance loss due to injury, and determination of extent of recovery and “fitness to compete”. Talent recognition and evaluation of potential performance. Team formation analysis.

� MEDICINE AND PHYSICAL THERAPY – evaluation of extent and

r type of motor dysfunction and/or injury. Monitor progress in program of rehabilitation. Quantify loss of use for workman’s compensation or insurance claims. Analyze effectiveness of prosthesis and isolate problems encountered in use of prosthetic devices.
