Which area should be avoided when performing deep tissue work?

The posterior clavicle is an area that should be avoided during deep tissue work due to its proximity to sensitive structures and the potential risk for injury. This region is not only closely associated with important muscles, such as those involved in shoulder movement, but it also lies near vital nerves and blood vessels. Applying deep pressure in this area can lead to discomfort or injury, as it can impact muscle function and cause pain in surrounding areas.

In contrast, the other areas listed, such as the forearm, lower back, and shoulders, generally allow for more safe and effective deep tissue manipulation when done with proper technique. Each of these regions can benefit from deep tissue work and are typically less problematic in terms of anatomical risk. Therefore, focusing on avoiding work on the posterior clavicle aligns with the principles of safe massage practices, ensuring the client's safety and comfort during the treatment.
