The deltoid muscle is part of the shoulder – it’s like the “cap” over the top of the shoulder joint that gives it the rounded appearance. The posterior (or “back/rear”) part of the deltoid commonly gets tight with overuse, typically with excessive lifting or activites that involve stabilising the shoulder for long periods, such as carrying kids around shopping centres!

Assessment by a health professional is recommended if you are experiencing tightness in this area, as it may lead to ongoing issues in the shoulder or surrounding areas such as the neck and mid-back.

Using the spiky ball as shown in the video above can help to give relief of deltoid tightness, and may help to keep painful symptoms at bay until a longer term solution can be found if necessary.
