  • Protocols can be setup to end by: reps, time or worklink protocols for all modes for automated multi-mode operation through all phases of rehab.
  • Pathology specific linked protocols for a complete rehab session of passive, ranging through to strengthening.


Reports

  • Six unique report formats – Print or PDF

- Exercise Summary Report – a graphical representation of the patient's status, progress and outcome over time. Plot Strength, Pain, ROM, and other user definable measures from the patient's test and rehab history.
- Graphical Evaluation
- General Evaluation
- Comprehensive Evaluation
- Progress reports
- Narrative cover letter
- Isomap

  • Graphical Evaluation is a simple report that uses color graphics to depict comparisons of peak torque between involved and uninvolved muscle groups, as well as to population normative values Report provides ability to type specific comments; a legend facilitates understanding.
  • General Evaluation includes the most commonly requested numeric data to accompany color graphic data depiction. Ability to comment is also available, as is the legend.
  • Comprehensive Evaluation provides data for 19 parameters in addition to a torque curve for each set.
  • Narrative cover letter is a form letter where the user can select certain phrases to describe the patient's performance and rehab status.
  • Progress Reports are available in the graphic, general and comprehensive report format progress report compares performance on one date with another.
  • Isomap reports provide data from a three-speed bilateral report.
  • The Isomap report illustrates using color intensity where the patient is having difficulty in relation to ROM, speed and contraction.


Database Manager

  • The enhanced Data Export Utility allows users to download all patient test data at one time, including both calculated and raw data.  Choose from .csv or .txt file formats for calculated data.  Raw data is exported as a .txt file, compatible with popular third party research programs, such as MatLab, LabView or BioPac.
  • The Rehab Exported Data Parser facilitates the process of working with exported data. The Data Parser, in the form of an Excel macro, has preformatted header files making it simple to convert .csv files into a report format.
  • Enhanced patient Database sorting – simply search by entering a name, portion of a name or initial.
  • Includes the ability to setup unique patient databases so that patient's /test subject can be separated. A popular feature when a System 4 is used in research.

 

Normative Data

The System 4 includes normative data values for peak torque to body weight ratios, as well as agonist to antagonist rations for most commonly referenced joints and protocols.

Expanded and updated isokinetic normative data is available for multiple joints including knee, ankle, hip, shoulder, elbow, and wrist from pediatric to adult, ages 5-83.

Advanced Applications
  • EMG Analog Interface Software
    Through the remote access port is an output of analog signals of velocity, torque and position data in real-time directly from the motor control Digital Signal Processor (DSP). In addition to the real-time data, a synchronization pulse is issued whenever the real-time data is updated. The synchronization pulse can be used by the monitoring equipment to know when the real-time data output has changed. Output Frequency, or update rate up to 2000 Hz. Four scaling values allow for optimal signal resolution.
  • Researcher's Tool Kit (optional)
    The System 4 Researcher's Tool Kit is a proprietary software package that provides the advanced user with customized motor control, movement tracking and data analysis.

- Front Panel Control Emulation - full set of controls as available on the front panel, with the addition of finer adjustments such as setting speed to any increment of 1 deg/sec, and setting torque to any increment of 1 ft-lb.

- Additional Control - for data monitoring and system controls, only previously used by the System 4 application.

- Remote Access Port Control - for the analog signal output, defines the scaling of velocity, torque, and position. In addition, the update frequency rate can be specified, along with the output mode, for example, the mode can be set to output the analog signals only when the System 4 is in an active state (START, not in Hold or Idle).

- Data Download for Motion Control - a user provided data file of positional data can be downloaded to System 4, and executed to follow a custom pattern of motion Tools such as MATLAB (from The MathWorks), MathCad (from MathSoft) or Prism (from GraphPad Software) can be used to generate these pattern files.
