BPMphysio Free-Form Module – Simple Assessment of Complex Goniometry

Free-Form detailAssessing complex goniometry, 3D movement of the human body, can be extremely difficult to understand and very expensive. Conventional tests tend to rely on 2 dimensional methods using simple tools or video analysis, neither of which is particularly useful in terms of accuracy or practicality. Using our expertise in digital motion analysis, the BPMphysio Free-Form Module has been developed to provide clinicians with a cost effective, easy way to collect 3D information.

The patented Free-Form Module provides the clinician and patient with live visual feedback as to the three-dimensional range of movement of the key joints in the human body: neck, shoulder, hip, wrist and ankle. There is a further category which gives the user freedom to plot the complete movement envelope of anything they think is of interest. Results are presented in a specifically-designed visual format which enables the user to clearly see how the range of motion has altered over time.

The Free-Form Module is being used by orthopaedic surgeons around the world. It is also being used in areas as diverse as determining whiplash injuries and to measure the effectiveness of ankle and wrist strapping in sport.  To see a worked example of the Free-Form Module, please click here.

The BPMphysio Free-Form Module delivers the following key features and benefits:

–  Displays complete 3D range of movement of key joints

–  Quick, complex goniometry capturing points for investigation

–  Live, animated polar plot graphical representation

–  Instant, objective key joint performance & historical analysis

–  Cost effective solution

Cost-effectively enabling the accurate, repeatable and recorded measurement of 3D movement promises to make assessing complex goniometry much simpler and cheaper for surgeons and their teams. This not only makes it easier to understand what a particular joint is doing, but it also supports the growing move to outcome-based assessment and funding. Ultimately, therefore, it benefits patients, surgeons and the wider health service alike.

The Free-Form Module is available as an upgrade to any existing BPMphysio kit, Standard or Premium version, for more information please click here.

  1. Title and test name

  2. Results table with current and selected sessions showing the maximum displacement angles for up, down, forward, back and rotation, or for the selected rotation circle (see 4). The comparison session can be selected from the Patient History screen or by selecting a session from the previous comparative data information box (marked 6). Note: the test area must be exited back to the Main Menu for a session to be saved

  3. Polar plot graphical representation of the patient moving indicated by the solid blue area. The dotted black circles indicate 30⁰ increments in angle and the straight dotted white lines indicate increments of 15⁰. The polar plot of the selected session for comparison purposes, appears as a solid red line.

  4. Selected rotation circle: The details of any specific data point on the polar plot can be selected by pressing or clicking the small dotted circle at the point of interest. The appearance of the selected circle will change upon selection to become white and the data for this point will appear in the Current column in the results table. If a comparative session has been selected, the data for the corresponding point will appear in the Selected column. To deselect the rotation circle, press anywhere in the gold-coloured area outside the plot area.

  5. Comment field can be edited to enter comments about the session (up to 300 characters). Initially this field holds a description of how the sensor is to be positioned on the patient and the starting point for the test.

  6. Previous comparative data information showing all the previous sessions during which this patient has performed the test. A data set for comparison can be selected by pressing or clicking on the relevant date in the box. Where data is for both upper or lower limbs, an R or L will appear next to the session date to indicate the side to which it relates.

  7. Patient information

  8. Control buttons, including patient orientation. Using the arrow buttons, the orientation of the patient can be switched between vertical and horizontal.
