The rhomboids are a group of muscles that run between the shoulder blade and the spine on each side. Similar to the upper trapezius muscles, they frequently become tight in people who spend long hours at the computer or in a seated posture. Excessive activation of these muscles in repetitive lifting movements is also responsible for an increase in tension in this area. Assessment by a health professional is recommended if you are experiencing increased tension in this area to avoid worsening of the condition and further imbalances as a result.
Using the spiky ball as shown in the video above can help to give relief of rhomboid tightness, and may help to keep painful symptoms at bay until a longer term solution can be found if necessary.
