10m Incremental Shuttle Walk Test (ISWT)

The 10m Incremental Shuttle Walk Test (ISWT) is an effective aerobic fitness test specifically designed to assess the functional capacity of individuals with Chronic Obstructive Pulmonary Disease (COPD). This modified version of the widely known 20m beep test is also applicable to children with cerebral palsy (CP) and other modified beep tests. By understanding the details and benefits of the 10m ISWT, you can gain valuable insights into its purpose and implementation.

Test Overview and Equipment

The 10m ISWT requires a flat, non-slip surface, marking cones, measuring tape, a pre-recorded CD or MP3 audio file (which can be conveniently created using the team beep test software), and recording sheets. Before the test commences, it is crucial to explain the procedures to the subject, perform a screening of health risks, and obtain informed consent. Additionally, basic information such as age, height, body weight, gender, and test conditions should be recorded. The course should be accurately measured and marked out using cones, ensuring that the distance between the cones is 9 meters.

Test Procedure

During the 10m ISWT, patients walk a path around the two cones, ensuring that the distance covered is approximately 10 meters. As the test progresses, the walking pace incrementally increases each minute. The test concludes when the subject is no longer able to maintain the required pace in time with the recording. With 12 levels of speed ranging from 0.50 m/s to 2.37 m/s, the test measures the total distance walked in meters. It is important to note that no encouragement is provided during the test.

Target Population and Benefits

Although initially designed for patients with pulmonary disease, the 10m ISWT can be utilized for a wide range of patients with various levels of disability severity. This versatility makes it a valuable tool in assessing functional capacity. Furthermore, the test’s simplicity and minimal equipment requirements make it accessible and practical for implementation in various settings.

Considerations and Scoring

As with all beep-type tests, the score achieved in the 10m ISWT can be influenced by factors such as practice and motivation levels, and scoring can be subjective. It is important to consider these potential limitations when interpreting the results.
