How is the back scratch test performed?

The back scratch test is a flexibility assessment specifically designed to measure the range of motion in the shoulder joints, particularly for older adults. This test simulates actions that require upper-body reach and mobility, which are important for daily activities.

In this test, one hand reaches over the shoulder, while the other hand reaches under the elbow. The objective is to see how close the fingers can come together or whether they can touch, indicating flexibility and shoulder range of motion. This method effectively assesses the ability to perform actions that require reaching behind the back, which can be commonly seen in tasks like putting on a shirt or fastening a bra.

The other options do not accurately describe the technique used in the back scratch test. Stretching arms out straight would not involve the necessary shoulder and arm positioning to assess flexibility in that manner. Reaching from opposite sides does not replicate the specific movements needed for this test. Holding weights while performing a stretch does not accurately reflect the purpose of measuring flexibility but rather adds resistance that could interfere with the assessment.
