For this modified test, you will need a specific sit and reach box designed for accurate measurements. Alternatively, you can create a makeshift ruler and box.
Pre-Test Procedures
Before conducting the test, explain the procedures to the participant and ensure they understand the risks involved. Obtain informed consent and record basic information such as age, height, weight, and gender. It is also important to perform a proper warm-up to prepare the body for the test.
Test Procedure
- Remove your shoes and sit on the floor with your back and head against a wall.
- Extend your legs straight ahead with your knees flat against the floor.
- Have someone place the sit and reach box flat against your feet.
- Stretch your arms out towards the box while keeping your back and head against the wall.
- Adjust the sliding ruler on the box so that the zero mark is at your fingertips.
- Place your hands side by side and slowly lean forward as far as possible, keeping your fingertips level with each other and your legs flat.
- Avoid jerking or bouncing to reach further.
- Hold the full reach position for two seconds and record your score.
Scoring and Variations
The score is recorded to the nearest centimeter or half inch as the distance reached. While this modified test accounts for variations in arm, leg, and trunk length, it follows similar scoring procedures as the traditional sit and reach test. Variations of the sit and reach test involve differences in the placement of the zero mark.

Advantages and Disadvantages
One advantage of the modified sit and reach test is its ability to account for variations in arm, leg, and trunk length. This addresses a limitation of the traditional test. However, a disadvantage is the requirement for a measurement box specifically designed for this test, which may not be readily available. Norms and comparisons for this modified test are also less common.
