What does the concept of loss of joint play hypothesize?

The concept of loss of joint play specifically hypothesizes that the facet joints of affected segments demonstrate a loss of joint play. This idea is rooted in the understanding that proper joint function is dependent on the ability of joints to move freely and demonstrate flexibility. When there is a loss of joint play, it indicates that the normal range of motion and arthrokinematics—the small, involuntary movements within the joint—are compromised. This restriction can contribute to a variety of musculoskeletal issues, leading to pain and dysfunction in the affected areas.

This concept emphasizes the importance of not only assessing the alignment of joints but also evaluating their ability to move smoothly and without restriction. Recognizing the loss of joint play helps chiropractors identify areas in need of adjustment and intervention to restore proper joint function and facilitate overall biomechanics in the body.
