Using a stick to perform passive shoulder rotation allows one to 'recenter' the joint and eliminate joint cracking or discomfort.

The idea that one can physically 'recenter' or realign a bone with such a light movement relies on a metaphorical rather than anatomical understanding of the shoulder. In reality, cracking (crepitus) is often due to cavitation (gas bubbles) or a tendon passing over a bony structure, rather than a structural misalignment. Physical therapy literature (observational studies and clinical reviews) shows that gentle mobility exercises, like the one proposed, can effectively relieve discomfort by improving joint lubrication and reducing muscle tension. However, the claim that the bone was 'out of alignment' and has been 'put back in place' is exaggerated: it is more a matter of improved flexibility and local proprioception. This exercise is a classic passive mobilization technique that remains safe and relevant for mobility, even if the mechanistic explanation provided is simplified.
