The Biering Sorensen Test: A Powerful Tool for Assessing Spinal Endurance and Building Spinal Strength
In the realm of Physiotherapy and strength training, having a strong and resilient spine is crucial. The Biering Sorensen test, named after the researchers who developed it, is a widely recognised assessment tool used to evaluate spinal endurance. Beyond being a test, it can also be utilised as an effective exercise to improve spinal strength and endurance. In this blog post, we will delve into the details of the Biering Sorensen test, its purpose, and how it can be integrated into a comprehensive exercise routine.
Understanding the Biering Sorensen Test:
The Biering Sorensen test is a simple yet demanding procedure designed to evaluate an individual's endurance in the muscles of the lower back and the surrounding core area. It involves assuming a horizontal position, with the upper body and legs unsupported and parallel to the ground. The test measures the amount of time a person can maintain this position, known as the "trunk extensor endurance time."
Purpose of the Biering Sorensen Test:
The main objective of the Biering Sorensen test is to assess the endurance capacity of the back extensor muscles. It helps identify any weaknesses or imbalances in the core region, which can contribute to lower back pain, and functional limitations. The test provides valuable information for designing targeted exercise programs aimed at improving spinal endurance and preventing back injuries.
Performing the Biering Sorensen Test:
To conduct the Biering Sorensen test, follow these steps:
1. Lie face down on a padded surface with the hips and legs secured.
2. Position the upper body parallel to the floor, with the arms crossed over the chest or placed behind the head.
3. Lift the chest and maintain a neutral spine position, with the neck in line with the rest of the spine.
4. Hold this position for as long as possible, without sagging or lifting the legs.
It's important to note that the Biering Sorensen test should be performed under the guidance of a qualified professional to ensure correct form and prevent injury.
Benefits of the Biering Sorensen Test as an Exercise:
Beyond its role as an assessment tool, the Biering Sorensen test can also be utilised as an exercise to strengthen the core and improve spinal endurance. By incorporating it into a regular workout routine, individuals can experience the following benefits:
1. Core Strength: The Biering Sorensen exercise specifically targets the muscles of the lower back and the core, including the erector spinae, glutes, and abdominal muscles. Performing this exercise regularly can enhance core strength, and endurance.
2. Spinal Endurance: By challenging the back extensor muscles to maintain an isometric contraction for an extended period, the Biering Sorensen exercise improves spinal endurance. This increased endurance translates into better support and protection for the spine during daily activities and athletic endeavors. A hold time of less than 1 minute has a higher likelihood of a recurrence of low back pain, whereas a hold time of over 3minutes significantly reduced the likelihood of a recurrence of low back pain. Interestingly, females perform better than males in this test, with the reason for this not being understood as yet, and older females better than younger females.
3. Injury Prevention: Weaknesses in this region can contribute to a higher risk of developing lower back pain and injuries. By strengthening the muscles responsible for maintaining proper spinal alignment, the Biering Sorensen exercise can reduce the likelihood of such injuries and promote long-term spinal health.
4. Functional Fitness: Strong core muscles are essential for performing various functional movements, from lifting heavy objects to maintaining balance during dynamic activities. The Biering Sorensen exercise helps develop the core strength necessary for optimal performance in everyday tasks and sports.
The Biering Sorensen test serves as a valuable assessment tool for evaluating spinal endurance, identifying weaknesses, and designing targeted exercise programs. It not only provides insights into an individual's core strength but can also be utilised as an effective exercise to improve spinal endurance and prevent back injuries. By incorporating the Biering Sorensen exercise into a well-rounded fitness routine, individuals can enhance core strength, promote spinal health, and enjoy the benefits of a strong and resilient back. Remember, it's always advisable to consult with a qualified professional before attempting any new exercise regimen.
