What is Jones Reach?

Jones Reach is a term used to describe the maximum distance that a person can reach overhead with their dominant arm while standing upright. It is primarily used in the field of ergonomics to assess a person's ability to perform tasks that require overhead reaching, such as working on high shelves or operating machinery.

Measuring Jones Reach involves standing with the feet shoulder-width apart, the back straight, and the shoulders relaxed. The dominant arm is then extended overhead, with the elbow fully extended and the fingers pointing forward. The distance from the shoulder joint to the tip of the middle finger is measured and recorded as the Jones Reach.

Jones Reach is an important measurement for ergonomists because it can help to identify potential risks for musculoskeletal disorders (MSDs). Individuals with shorter Jones Reach measurements may be more likely to experience discomfort or pain when performing overhead tasks, as they may have to overextend their reach to complete the task.

To improve Jones Reach, individuals can perform regular stretching exercises that target the muscles of the shoulder, back, and arms. These exercises can help to increase flexibility and range of motion, which can lead to improved Jones Reach measurements.

Overall, Jones Reach is a valuable measurement for ergonomists and individuals who want to improve their overall health and well-being.
