The Pitfalls of Screen Capture in Spinal Motion Testing


In the realm of medical diagnostics, especially when assessing spinal injuries, the accuracy and reliability of the tools and methods used cannot be overstated. One critical area of concern is the testing for excessive motion to detect damage to spinal support ligaments, which are among the most significant injuries impacting patients today. However, relying on outdated screen capture technology for this purpose is fraught with inaccuracies and risks. 

The Role of Spinal Support Ligaments

Spinal support ligaments play a crucial role in maintaining the stability and function of the spine. Injuries to these ligaments can lead to severe pain, disability, and a range of other health issues, often more impactful than disc herniations. Therefore, accurate detection of ligament damage is vital for appropriate treatment and patient care.

Flaws in Screen Capture Technology

1. Inherent Inaccuracies: Screen capture technology essentially involves taking a digital snapshot of an existing image, such as an X-ray. This process introduces several layers of potential inaccuracies. For instance, when capturing an image from a screen, the calibration required to measure distances or assess motion can be flawed. Placing calibration points manually introduces human error, and the screen capture itself can distort the image quality.

2. Outdated Software: Many of the software programs that rely on screen capture technology are antiquated, some being over a decade old. These programs may not be equipped with the latest advancements in imaging and diagnostic accuracy, making them unsuitable for modern medical testing standards.

3. Error Accumulation: Each step in the screen capture process, from initial image capture to the placement of calibration points, introduces potential errors. When multiple images are compared to assess motion, these errors accumulate, leading to significant inaccuracies in the final analysis.

The Need for Unbiased, Advanced Testing

Given these limitations, it is crucial to use unbiased, independent third-party evaluations performed by medical radiologists with access to the latest imaging technology. Companies like Spinal Kinetics have pioneered the use of advanced AI technology to improve the accuracy and standardization of excessive motion tests. This approach ensures that the testing is performed at the highest professional standards, reducing the risk of diagnostic errors.

Why You Should Avoid Billing for Inaccurate Tests

Using outdated screen capture technology not only jeopardizes patient care but also exposes medical practitioners to legal and ethical issues. Billing for procedures that rely on inaccurate or outdated technology can lead to scrutiny and challenges from experts who understand the limitations of these methods. Therefore, it is advisable to avoid billing for tests performed with screen capture technology and instead invest in the most reliable and advanced testing options available.


Excessive motion testing is indispensable for diagnosing spinal support ligament injuries accurately. Relying on outdated screen capture technology compromises the quality of these tests, potentially leading to misdiagnoses and inadequate patient care. By choosing advanced technology and independent third-party evaluations, medical professionals can ensure they provide the best possible care for their patients, reflecting the true extent of spinal damage and facilitating appropriate treatment plans. Always opt for the best and most current technology to uphold the standards of medical diagnostics and patient care.
