The lateral side-bending flexibility test is a simple measure of trunk flexibility. The test measures the average range of movement in lateral flexion of the thoracic and lumbar spine and pelvis. Participants have to bend laterally as far as possible to each side from the standing position.
purpose: measure the lateral flexion of the thoracic and lumbar spine and pelvis
equipment required: tape for marking the ground, ruler or tape measure.
pre-test: Explain the test procedures to the subject. Perform screening of health risks and obtain informed consent. Prepare forms and record basic information such as age, height, body weight, gender, test conditions. Measure and mark out the test area. Perform an appropriate warm-up. See more details of pre-test procedures.
procedure: Subject stands upright against a wall on two parallel lines at right angles to the wall and 15 cm apart. The arms are held straight against the sides of the body. The level of the middle finger on each side is marked with a horizontal line on the side of the thigh. The subject is then asked to slowly bend sideways as far as possible while maintaining contact between their back and the wall. Two attempts each side is performed. The distance between the first and last position of the middle finger is recorded.
scoring: Record the best measurement for the left and right sides.
advantages: this is a simple and quick test to perform, and it is possible for participants to self-administer the test.
